Our project with Bassmaster: Will Lake Y become a bass fishing heaven?

By Lochow Ranch

Turning an average, underperforming lake into bass fishing heaven requires some thought, planning and know-how.

Getting those details right is the goal of our new project with Bassmaster, “The Lake Y Project.”

The resulting project is a complete video series, which just aired its first episode at: https://www.bassmaster.com/lakey

The series examines how we tackle Lake Y, an anonymous 56-acre creek-fed lake in Alabama. Bassmaster says Lake Y “could well represent the majority of small lakes and ponds scattered throughout the country.”

In Episode 1, James Hall, editor-in-chief of Bassmaster Magazine, introduces the project with our president, John Jones.

John first studied Lake Y in the spring and did a walkabout, identifying problems and opportunities.

Overall, John says “there are a lot of chances to grow a lot of fish,” but Lake Y also has a lot of problems that need to be addressed.

“Left unmanaged, small fisheries, say from 3 to 100 acres, can get out of balance a lot faster than you would imagine,” Bassmaster explains in its series description.

“Bass can become scarce from predation of other critters, or worse, overpopulate a lake and stunt. Non-desirable species (at least to hardcore bass anglers), like catfish, gar and carp, can create such a biomass in limited space that largemouth simply cannot thrive. Cover and structure can deteriorate, vegetation can choke out open water and water quality can become unbearable for fish in a matter of a few years.”

In the video, John advises that Lake Y owners start an improvement strategy with satellite photos identifying other water body influences and an examination of the lake’s history: when it was built, watershed influences and management approaches. He identified Lake Y as being off color and in a shallow ravine with a small dam.

A lot of people find a great dam site, John explains, but they don’t put money into deepening the lake, which could have cost 10 times as much. But that doesn’t have to be a hindrance, he adds.

His visual assessment also included evidence of otters, and identified issues surrounding the lake’s number and condition of boats, fish feeders and spillway.

It’s a beautiful lake, John says, but multi-owner lakes (as this one appears to be) have to be handled very differently, and multiple ownership could be a help or a hindrance with different priorities. Among many other observations, he also notes the creek could present some challenges with species diversity, and managers should probably come up with a catfish control program.

John notes, “You don’t have to spend a lot of money to have a great lake, but money speeds things up.” He says he asks customers to give him a budget or a timetable for goals. Now that the visual assessment is complete, the next Lake Y episode will focus on its electrofishing survey.

Electrofishing uses an electric current to briefly stun the fish population. This then allows for an accurate assessment of species, size, relative abundance and growth rates of a lake’s fish.

It’s an excellent tool for correcting an out-of-balance pond. Stunted fish or unwanted species can be easily and quickly removed as part of the service. And the survey acts as the reference point for a long-term pond management plan and provides clues for corrective stocking and harvest recommendations.

“In the end, we hope to inspire you to not settle for unimpressive or average fishing, because you can do something about it,” Bassmaster says.

Follow us on Instagram, Facebook or Twitter to see the progress in Lake Y in coming weeks.

Fish Kills: What to watch out for as summer heats up

By Lochow Ranch

Summer is officially here, and all lakes and ponds are at an increased risk of a fish kill.

While they are not necessarily common or completely preventable, it is good to be advised on what can happen and what to look for because lately we’ve had a sharp increase in fish kill calls.

By far, the overall most common cause of fish kills is lack of oxygen and summer is the deadliest season.

During the summertime as air temperature and length of day increases, most lakes (if not fed by a well) begin their annual drop in water level.

Surface water becomes super-heated during the day and since water density decreases as temperature increases, stratification or separation between water masses at a thermocline occurs.

pond management texas arkansas louisiana oklahoma

That is the cold water you feel at six or so feet deep. Little to no mixing occurs below the thermocline, which results in the water below the thermocline becoming anoxic or depleted of oxygen.

Depending on the surface area to volume ratio of your lake, this stratification is currently occurring to some degree, except in lakes that have appropriately sized subsurface aeration systems.

These conditions put lakes at an increased risk of a fish kill.

Other anoxic conditions can occur when weather changes drastically, for example during big rain events or very windy days lakes can experience a turnover. This normally happens because high amounts of rain can super-cool surface water causing it to sink, which causes the anoxic bottom water to come to the surface.

The combination of sharp changes in temperature and low oxygen levels can cause a fish kill. Small deep lakes with large watersheds have the highest risk of a turnover-related fish kill.

Some other causes of fish kills are:

  • very dense plankton blooms or green water
  • blue-green algae blooms, which produce toxins
  • weed decay, which uses oxygen
  • excessively dense weed growth, which consumes too much oxygen overnight

Lakes that have dense phytoplankton blooms are also at risk of a fish kill. If the phytoplankton biomass exceeds a critical level there can be a simultaneous rapid die off. The resulting bacterial oxygen usage from the decomposition of algal cells can reduce oxygen levels low enough to kill fish.

Extended periods of overcast skies and increased turbidity from rain events can also cause a rapid die off of phytoplankton.

All lakes, including those with subsurface aeration, are at risk of this type of fish kill. Closely monitoring water color and taking visibility readings using a Secchi disk can help with management decisions.  Assessing summer kill causes and weed control are among the most vital management duties.

Certain corrective measures can be taken to reduce phytoplankton density but must be done so proactively.

As always, please let us know if you notice something “off” with your lake, especially during these hot still days.

Ready for the season? Get those fish stocking orders in soon

By Lochow Ranch

You might already be picturing your trophy bass Instagram snaps. But before that happens, it’s time to get your stocking plans set for the season and address any issues with your pond or lake’s inhabitants.

Springtime is a great time to assess your pond’s fish populations to ensure you’ll have decades of good fishing ahead.

As waters start to warm as we head into summer, we recommend moving forward with spring stocking orders in the next couple of weeks. That’s especially true for supplemental forage or Florida Bass fingerlings.

Balancing prey to predators for strong growth rates requires expert analysis of your pond management and fish stocking needs.

Our team of pond stocking technicians, biologists and other professionals at Lochow Ranch Pond and Lake Management can help you plan the perfect mix for your particular conditions and goals for your lake.

Fish stocking has been practiced for hundreds of years, and a lot of thought should be put into selecting types of fish, as well as whether to introduce non-native species.

What fish will work best in your pond or lake involves many variables, including its size, your goals, and other factors. Very small ponds under one acre have special considerations, and so do very large lakes of many acres. They must be stocked and managed in different ways and present distinct challenges.

A fish population analysis through electrofishing or gill netting will determine which species need to be stocked to bring your lake to its true trophy-growing potential.

Our experts create a recommended fish stocking plan that takes into account your lake size, location, health and condition as well as your desires. Lochow offers all of the region’s most popular species of fish, such as basstroutsunfishcatfishforage fish and many other species.

If you are noticing nuisance vegetation growing, this is also the right time to schedule treatments, and we offer a complete range of traditional options and natural biological alternatives based on your needs, desires and our years of expertise in dealing with similar bodies of water around Arkansas, Oklahoma, Louisiana and Texas.

Whether you want a lake completely free of weeds, or perhaps a 25 percent vegetation coverage to promote fish growth, our comprehensive vegetation control programs offer affordable and effective solutions to vegetation control and management issues that threaten the health of your pond, its fish and the desirable plant life in it.

For landowners who want to create their own fishery experience, we provide a complete, unmatched expert menu, from construction with an initial fish stocking plan to long-term pond management.

Fishery tips: Prepping your fishing lake for a great season

By Lochow Ranch

Fishery management experts know that year-round pond and lake maintenance is key to keeping your favorite fishing pond healthy and productive.

The leading reasons the equilibrium in your lake could be off include over- and under-harvesting of predator fish, introduction of undesirable fish species, and summer kills, as well as excessive weeds, poor water quality and lack of fertilization.

Qualified experts like those at Lochow Ranch Pond & Lake Management can help turn around a failing fishery or enhance a stable one by addressing these various issues in an annual plan that tracks progress and addresses needs.

Otherwise, Texas A&M AgriLife Extension Service warns that Texas farm ponds aren’t managed at their highest potential for fish production.

Lochow Ranch can assess fishery populations using nets or shocking equipment and use state-of-the-art equipment to collect data and determine the precise program for getting your body of water back on track.

Surveying Your Pond’s Population

Electrofishing Arkansas Louisiana Texas Oklahoma

An excellent way to begin is with an electrofishing survey, which is a primary tool for correcting an out-of-balance pond.

These surveys accurately assess current forage and sport fish populations and quantify wintertime Cormorant or otter damage. Fish populations also are sampled to determine species, size, relative abundance and growth rates. Click here to learn more.

Planning Pond Stocking

pond stocking services

Pond stocking is another important consideration when you want to maximize the potential for your fishery.

What kinds of fish will work best in your pond involves many variables, including your own goals for your pond or lake. For example, you need to carefully assess the impact of introducing non-native species into your pond. It’s important to be aware of the fish types that can live together in harmony so your pond can sustain a healthy ecosystem. Learn more by clicking here.

Getting a grip on pond weeds

Aquatic vegetation is the cause of 80 percent of low dissolved oxygen fish kills in Texas. And the issues are complex enough that expert advice is recommended.

As we detailed in a series of recent postings about pond vegetation control, there are a range of vegetation control techniques. Mechanical controls include pruning and cutting back pond weeds. Biological controls include introducing grass carp and tilapia, two types of vegetation-eating fish. Chemical means of vegetation control include herbicides and algaecides.

Click here to learn more about how the experts at Lochow Ranch can plan appropriate vegetation control for your lake or pond.

Fertilizing your fishery

Just as you would fertilize fields to increase crop yields, you should fertilize a pond or lake to provide phytoplankton with adequate nutrients for fish growth.

Proper fertilization increases food availability throughout the food chain and indirectly increases the total amount of fish a pond can support. Ponds should be limed before fertilizer is applied, which is important because it increases pH and alkalinity.

Even without fertilization, this may improve available nutrients which can support a phytoplankton bloom. Click here to learn more.

Adding aeration

In order to avoid problems, pond and lake owners also should be inspecting aeration and fountain maintenance or considering their implementation.

Repairs could address obvious signs of wear or just the cleaning of filters and   screens. Lochow offers a range of aeration systems and fountain systems for   ensuring your pond’s oxygen levels are optimal.

Forage for your fishery: key spring lake management tips

By Lochow Ranch

As our ponds pull out of the winter cold and begin to heat up, our gamefish metabolisms rise, and the spring glut is on.

Forage populations generally take a pretty big hit over the winter. Depending on the lake, the spring glut can have a lasting impact on forage and the predators that consume them.

Forage fish are generally smaller fish or crawfish that are the food source for your larger gamefish, such as bass.

Between diving cormorants and pelicans and continual predation by largemouth bass, peak forage populations of the fall season are heavily depressed and must rebound in order for lakes to maintain peak production.

This week, we’ll take a look at some common forage management issues and how to resolve them as part of your fishery management plan.

Goal-Oriented Management

As with most aspects of fishery management, establishing your fishery’s goals is paramount to determining your overarching pond and lake management strategies.

Is your primary target feed-trained bass? Do you mostly care about hybrid stripers? If so, forage fish may not matter a whole lot for your fish. Sure, healthy forage always benefits gamefish, but fish that consume pelleted feed can pretty easily shift their diet away from forage whenever populations are depressed.

If your target species are trophy Florida Largemouth Bass, native non-feed trained bass, or crappie, forage populations are essential.

Let’s take a look at the main forage species for each target gamefish and see how their populations can be managed for the greatest possible impact.

Target Fisheries

Trophy Florida Largemouth Bass

Trophy bass require good forage availability throughout their lives to achieve the outsized proportions for which they are so prized.

Good trophy management requires regular monitoring and rapid intervention if forage populations crash. Generally, these fisheries will rely primarily on bluegill, shad, and crawfish in that order of importance, with additional forage support from redear sunfish, golden shiners, silversides, and in some cases tilapia.

Having some diversity in your forage species helps to provide food for bass as certain populations experience natural fluctuations.

It is important to have good forage diversity in both species and especially size. To ensure all of your bass have plenty of food, careful and regular analysis of small, medium, large, and jumbo-sized forage should be made to determine if your forage is adequately supporting your lake’s bass.

Early in life, bass consume all sorts of fry (recently hatched fish). As they grow their diets shift to small sunfish and fry. In the next stage of life, threadfin shad can really make a huge difference in pushing bass growth. These fish combine with medium sunfish and medium shiners to supply bass to a couple of pounds in weight.

Next your bass will shift to eating large sunfish, threadfin shad, shiners, goldfish, and crawfish. Finally, if all goes well, bass begin to push into the trophy stage where they will continue to consume the latter forage but also begin to take larger meals, which could include jumbo sunfish, gizzard shad, jumbo golden shiners, larger goldfish, trout, and any other large fish they can swallow.

These various forage populations should be supported through supplemental feeding, habitat management, and pond stocking as appropriate.

Non-Feed-Trained Largemouth Bass

Even if you aren’t trying to grow the next world record, home-grown bass fisheries still need adequate forage to develop good populations of healthy fish.

Keep an eye on your forage and develop good populations of fish fry, and small, medium, and large forage.

Most forage is principally helpful in the 1-4” range, with some benefit being had from forage up to 6” in length. In general, forage above 6” in length are too large to serve as much benefit to your average native bass, which generally tops out around 7 pounds in weight.

Threadfin shad are excellent supplemental forage for spring stockings with golden shiners a close second. Golden shiners and goldfish are excellent supplements in the fall.

Once established, bluegill and redear should generally be maintained in perpetuity in well managed fisheries (assuming you don’t have a bunch of hungry cormorants or pelicans land on your lake) and generally won’t need to be restocked.

Crappie

Crappie are notorious for boom and bust reproductive cycles and slow growth.

Care must be taken to help these fish have plenty of food at the right times. Generally, fish fry, silversides, small threadfin shad, small shiners, and small sunfish are paramount to a healthy forage supply.

Large forage will actually remove the food base for these smaller fish, which would depress their numbers and easily result in stunted crappie.

Forage Specific Management

Regardless of your desired outcome, a few key factors must be considered in order for forage to thrive. Let’s take a look at three primary factors, habitat, food, and predation.

Good Habitat

First, habitat must be maintained to provide shelter for some of your forage.

This helps a given lake maintain a breeding population of various forms of forage. Habitat like cover is particularly important for bluegill and redear sunfish. Generally good habitat will involve some beneficial vegetation and some non-living habitat like felled trees or artificial structures. Habitat for open water schooling fish is just going to be that, expanses of open water where they can shelter by schooling together.

Food For Forage

Second, forage food must be plentiful for strong populations.

Sunfish diets can be supplemented with fish food as can that of golden shiners and tilapia. Otherwise, healthy populations of aquatic insects and fish fry are necessary to maintain those populations. Threadfin shad are planktivores and a healthy plankton bloom is essential for these fish to thrive and achieve their potential.

Moderate Predation

While we certainly grow forage to be eaten, we want predation to be commensurate with forage populations.

If the right number of gamefish is maintained, forage numbers will stay high and gamefish will thrive. If predator populations exceed what the forage base can support, forage populations will crash.

Be sure to conduct the necessary annual harvest of predatory fish to ensure that forage populations thrive. It goes without saying that no fishery can sustainably support predation from huge flocks of avian predators without some supplemental stocking from time to time.

Plan Forage For Your Dream Fishery

Forage matters. Know what forage your preferred gamefish need and make sure you have stocked the right species. Make it a regular part of your fishery management and pond stocking plans.

Assess your lake forage on a regular basis and adjust management strategies to promote healthy forage populations.

Adjust the habitat as needed, keep your forage fed, and limit predation as appropriate.

Your lake will thank you with smiles and your fish will thrive.

Love your lake? Let’s learn what lurks there

By Matt Ward

In order to accomplish great things, we have to take an honest look at where we are and decide on where we want to go.

This is no less true of lake and pond management than it is of life.

Knowing how things are in your pond at any point in time is the only way to be sure of what fishery management steps need to be taken and how a fishery is progressing over time.

Maybe you are planning pond stocking, wondering how pond weeds are affecting your fish, thinking about adding bass or trout, or wondering if you need to add forage fish.

electrofishing services for pond management

The right first step is to assess the current fish population in terms of numbers, types and size.

Multiple assessment tools have been developed over time including gill nets, hoop nets, seining, pole and line, and electrofishing.

All of these methods have a place and have been developed to move fishery analysis from the “yarn” to science. Each of the first four methods are generally biased to a specific type or size of fish, making general assessment difficult.

Electrofishing is the closest thing we have to a broad-spectrum fishery analysis tool. Electrofishing is somewhat biased toward shallow water fisheries, but generally offers the most complete analysis of the widest variety of fish in a given pond or lake.

That’s why we are giving away five free electrofishing surveys to lucky Texas pond owners. There is no better way to learn what lurks in your lake.

What is electrofishing?

Electrofishing involves the application of specific current to a given water body with the goal of temporarily stunning fish in order to safely collect them. Sampled fish are netted and analyzed as needed to assess the fishery.

After analysis, fish are safely returned to the water to swim away unharmed. Equipment to conduct this work is quite sophisticated and requires extensive experience to maximize sampling efficiency and minimize risk to fish. Desired current varies in each fishery, just as conductivity of waters varies across the country.

Electrofishing Arkansas Louisiana Texas Oklahoma

Our electrofishing equipment is optimized for scaled fish and involves a gas generator, which is connected to a rheostat that allows us to cycle between DC/AC, various electrical frequencies, and a wide variety of applied voltages.

These settings are combined with a variety of telemetry equipment that allows us to track amp pulls and the load on our generator at any given point in time. In addition to varying settings on the rheostat, we have a variety of different hardware settings we can use to manipulate our anodes and cathode to optimize our equipment to a given water body.

Electrofishing involves applying very powerful current to water and as such involves significant risk. This risk is managed by crew training and safety policies that ensure the safety of our customers and ourselves.

Be sure to pay attention to safety instructions given prior to an electrofishing survey.

What information is collected?

Sampled fish are recorded for species and relative abundance. Next, the relative size distribution of all species is recorded. Specific gamefish are then measured and weighed to determine their relative body condition. This data is recorded and plotted against standards that have been set in scientific literature.

In addition to these direct observations, every decent fishery manager should be making many secondary observations that are critical to developing management strategies.

These include aquatic vegetation, non-living cover, water temperature, clarity, depths, predator signs, and access. All fishery assessments should also include a basic water quality analysis to check for buffering capacity and nutrient loading.

What information is gleaned from this data?

Fisheries managers use this information to understand the general species composition of a particular fishery.

Combining that with relative size data, managers are able to provide a good understanding of the forage availability for various gamefish. Gamefish data allows for an understanding of the size structure of a population and the relative health of gamefish of various sizes.

Ultimately, this data is used to determine the predator-to-prey ratios and general forage availability. In short, we find out what your fish are eating and if they have enough to eat; if you have enough fish in your lake to enjoy the fishing; if you are getting hit by predators; and the list goes on.

This information allows us to figure out what the best fish to stock would be and how many of those fish could be stocked. This kind of analysis can easily save a pond owner many thousands of dollars per acre that could be wasted by stocking “blind.”

When To Shock

The best time to shock a lake is when you need to understand the state of that fishery.

This can really be done most any time of the year with one general exception. Hot weather is hard on fish, so generally we try to avoid shocking most lakes in the heat of summer (but even this rule has exceptions).

In a perfect world, we shock all lakes annually in the fall to understand trends. The fall is preferred because standard fish data is also collected in the fall giving the best possible picture of the state of a given fishery.

That being said, we shock throughout most of the year to assess loss to predation, the strength of a spawn, fish loss due to a flood, and to conduct selective harvest.

There are also specialty shocking events that can serve specific purposes. My favorite is the pre-spawn shock for largemouth bass. Because largemouth bass females peak in weight and move shallow just before the spawn, this is the best time of year to go looking for trophies!

Final Thoughts

Electrofishing is a very safe method for sampling fish by stunning fish for short periods of time while data is collected. Check out our video of the process here.

Note that fish can occasionally be killed by the stress of electrical shock or by getting hit by the electrofishing boat’s propeller, but this loss is very rare.

Efficiency does vary though, and it should be noted that standard professional electrofishing is highly effective on scaled fish that inhabit shallow water and somewhat less effective on deep water denizens such as crappie or scaleless fish such as catfish.

All in all, if you love your lake, schedule an electrofishing survey and find out how to make your fishery shine.

Looking out across the country, you can see countless waterbodies dotting the landscape – ponds and lakes of every size.

Most will have fish, but they’re subject to endless pressures: droughts that constrain fisheries; floods that scatter fish about the countryside; waterfowl gathering calories for migration; fishermen invited or not who ply their lines; or even otters grabbing a meal as they pass through the landscape.

Sooner or later virtually all water bodies will need to be stocked with fish in order to support healthy fisheries. Whether minimal inputs or high-catch rates are your game, thoughtful stocking is key to lake success and effective fishery management.

Let’s take a look at a handful of the most popular fisheries and discuss how pond stocking can best be employed.

New Lakes

New lakes offer the most opportunities for lake owners.

Careful selection of the timing of introduction, species, and numbers of fish stocked is key to producing the kind of fishery a lake manager wants. A good pond stocking plan should take into account expectations during a drought, the desired fishery outputs, water body physical composition and available cover. A good pond stocking plan should also be preceded by water testing to make sure all is in order.

Trophy Bass

If you are looking for a trophy bass fishery, you will need to introduce forage fish at the right time, helping small forage to peak at the time that you introduce fingerling Florida bass.

Trophy fisheries are relatively low-density fisheries and so a pond stocking plan should be put in place to boost your lake’s carrying capacity if you want consistent catch rates. This should be accomplished with pelleted fish food and/or supplemental forage.

Feed-trained Largemouth

Other popular fishery options include feed-trained largemouth bass, which can provide some of the highest catch rates around.

Well over 100 feed-trained bass can be stocked per acre as long as feeding rates are kept up. This kind of fishery is ideal for casual fishermen, the young, or the young at heart. Feed-trained bass can easily hit weights of 5 pounds or more. While feed-trained bass are fertile, young do not learn to eat fish food so restocking is needed to maintain their populations.

Hybrid Striped Bass

Hybrid striped bass can also be stocked at high rates allowing for exciting fishing.

Hybrids are sterile, but rapidly grow to 5 pounds with some achieving well over 10 pounds in weight. These fish are relatively inexpensive and sold at small sizes that rapidly grow into hard-fighting bruisers.

Contrary to popular belief, hybrids can be stocked in small waters and often offer a tremendous option for small pond owners. Most hybrids live for seven or eight years in the South, achieving much greater ages in the North. Restocking should be planned to maintain populations.

Catfish

A quality catfish pond should almost always be stocked with channel catfish. Blue catfish do grow larger and can be stocked if desired, though these apex predators usually grow so large that only low numbers of fish can be supported in a given pond or lake.

Flathead catfish are even more problematic and tolerate even lower stocking densities. In channel catfish fisheries baitfish are beneficial though their value is secondary to pelleted fish food for feeding the fish.

 

Channel catfish taste excellent and can be stocked in relatively high numbers when supported with supplemental feed. Up to 500 catfish can be stocked per acre. Higher stocking rates should be accompanied with high harvest to keep the fishery healthy.

In the aquaculture industry, channels are normally grown to a couple of pounds before harvest so plans should be made to begin harvest of channel catfish within a year or two of stocking to keep populations in check as the pond ages.

Existing Fisheries

Existing fisheries may require stocking for a variety of reasons.

Put-and-take fisheries with feed-trained bass, hybrids and catfish should be restocked to maintain populations of a finite resource of fish. Forage fish may need to be stocked to recover a population if predator fish populations exceed their food source.

Lakes that recover from droughts often need stockings to recover fish populations that have shrunk with falling water levels. Some situations are simple, but most require an intimate knowledge of the fishery to be correctly selected.

Effective stockings of existing fisheries should generally be preceded by a thorough survey of the fishery. Beware of services that offer to stock large numbers of fish without taking the time to know your fishery.

One stocking you can generally pursue without a prior fishery survey is Rainbow Trout. Rainbow Trout provide an exciting winter fishery when stocked in sufficient densities.

These fish won’t survive long once water temperatures warm in spring, but can provide excellent table fare in the meantime. That being said, trout are predatory fish so do know that trout will generally lower forage populations over the winter, so be sure to provide them with plenty of fish food to minimize forage loss.

The key to getting the most from your body of water is to develop a strategic pond stocking plan as central to your fishery management.

When deciding what fish to stock, make sure that your pond stocking plan is developed by an experienced biologist with a solid reputation. Good biologists will design a pond stocking plan that will help you efficiently pursue your fishing goals for years to come. When you get your stocking plan, ask if the person you hire will provide support as needed after the initial stocking.

Ponds and lakes are dynamic environments that can experience a variety of problems that may require intervention. An ounce of prevention … well, you get the idea ….

The Big Freeze: how did last week’s arctic blast affect Texas ponds and fish?

By Matt Ward

First, let me say that we sincerely hope that all of you are OK after last week’s extreme winter weather. Our thoughts are truly with those who experienced the worst of the power and water outages. If you were among this group we hope that you are on the road to recovery this week.

I have to say it was heartening to see so many coming together to help each other out during the big freeze.

On a related note, we have received a good number of questions from our clients about the effect of cold on ponds and lakes so we hope this brief summary helps to answer most of your questions.

Please drop us a line if you have any other specific concerns or questions we can answer around fishery management or pond management in general.

What about the fish?

As most of you know, fish are cold-blooded (“ectotherms” would be a more scientifically correct term for the science nerds).

This means that during our unusually cold weather, fish body temperatures mirrored the lake temps and as such fish metabolisms slowed to a crawl. In general, most of the fish that live in our waters are accustomed to short periods of cool weather and will have fared the weather just fine.

That being said, there are a few fish that are a bit more cold-sensitive so we do want to keep an eye out for these fish and note any losses.

Threadfin shad

The most cold-sensitive fish we have in our lakes are threadfin shad. Threadfin generally experience at least partial die-offs when water temperatures dip below 45 degrees Fahrenheit.

On top of this, threadfin shad get highly lethargic and even the fish that would have survived the cold will generally get swallowed up by largemouth bass which are much less affected by the low water temps.

With last week’s cold front, we expect that we lost most or all of the threadfin shad in most every small impoundment in the state.

We’ll be monitoring populations in lakes with large amounts of shad, but we don’t expect to find shad left over. Threadfin shad availability will also likely be down this year, so expect supplies to be short as well.

If you want to restock the fish, get your orders in early and know that demand should outstrip supply.

Florida Bass

While far more cold-hearty than threadfin shad, Florida bass are famously more susceptible to cold than their northern counterparts. While cold weather can kill off Florida bass, fishery managers stock Florida bass successfully well north of the Red River.

Losses in Texas should be minor though the farther north you are, the more attention you should pay to your Florida largemouth bass stock. Northern largemouth bass are fully adapted to cold water like we experienced last week, but certain populations like feed-trained bass can be a bit more susceptible to rapidly cooling water temps.

While we expect that threadfin shad are the primary victim of last week’s arctic blast, an electrofishing survey is the best way check for any other significant impacts.

Predators get active during cold

Fish instincts do generally cause fish to go deep during cold weather, providing a small degree of protection from predators. But cold weather also increases the metabolisms of both otters and birds who need to eat more to keep warm.

While your fish may survive the cold just fine, predator consumption will rise and fish losses from predation should be expected. Do what you can to minimize loss, but look for changes in catch rates and be prepared to stock.

Vegetation takes a hit

The one really bright side of last week’s weather is that the cold-snap should provide a welcome reprieve from undesirable early season growth of pond weeds.
Cold water temperatures have likely pushed the growing season back several weeks allowing for a thorough winter kill and forcing pond weeds to grow again from seeds and roots.

Note that marginal vegetation will likely have turned completely brown. But have faith. Most native vegetation is built to survive this kind of weather event and growth will return once temperatures warm. While browned-out growth can be removed for aesthetic purposes, know that removal will likely slow recovery.

Forage fish lose cover

Whenever we lose submersed vegetation, forage fish often lose a majority of their preferred cover.

This cover loss can enable bass to depress forage populations which may not recover for several months or until supplemental stockings are deployed.
These kinds of situations really demonstrate the value of non-living cover which provides stable cover regardless of winter vegetation die-back.

The best way to monitor the impact from winter forage loss is to monitor bass health as the weather warms. If bass remain fat and healthy forage loss is likely not a concern, while thin bass indicate a lack of the same. While all gamefish benefit from robust forage populations, do note that pelleted feed-based fisheries need not be concerned about temporary forage fish depressions as gamefish rely primarily on fish food.

Keep an eye on your fishery

All in all, cold weather certainly impacts fisheries in significant ways. These impacts are generally specific to each fishery and difficult to predict across the board. In general predation will have increased and forage fish populations will have fallen. To keep your fishery developing appropriately you should monitor the fishery and make needed adjustments in a timely manner to keep your fishery developing appropriately.
