Bass Harvest…..it never stops

The pond being electrofishing today has a common problem that not many property owners think about but something we see often. The lake was stocked a few years back and everything was great. Owners get caught up in the excitement of seeing bass, bluegill, shell cracker, and shad going into the pond. The real work starts a few months later. Among a new lake owners duties is bass harvest. The initial bass that are stocked in a new pond will be the best class ever.

These are the original bass fingerlings. They are eight years old at this point. When a fishery reaches this point it’s important that the following year classes are managed very strictly. Failure to do so will result in lots of stunted bass that typically range in sizes of 8-12″. People are often blinded by catching lots of big bass while the runts’ numbers keep growing. Electrofishing opens eyes to the problem brewing underwater.

If you own a lake less than ten years old your best bet is to harvest bass aggressively and add habitat. Shoreline trees are a great start as the are usually small and will fall directly into the water. Digest these two tips then make them happen on your home water.

 

Lake Liming for New Lakes

georgia pond construction

New lakes are a beautiful thing. They are ripe for the imagination. Property owners can make humps and points to bounce a football jig off or sticking tree tops mid-lake that will one day result in a bass crushing a top water plug. However, till that point we have to do the small things that make those big dreams possible. One of the small things that results in big dividends is lake liming. Proper alkalinity also fertilization programs to be effective. Fertilized lakes can hold 300-400 lbs per acre of fish while unfertilized lakes hold 40-100 lbs per acre. Lime is a composed of basic compounds so it keeps pH cycle much more stable. Stability is king in nature.

Break in the Rain

Anyone living in the Southeast is probably wondering if our temperate deciduous forests is slowly becoming a rain forest with the amount of rain we are battling. After a few dry days we tip toed the lime barge across the virgin ground.

Georgia Lake Construction
New lakes in the North Georgia mountains are prime candidates for liming. There are a few veins of good soil in North Georgia but for the most part the soil is poor.
Georgia Lake Construction
Lots of standing timber and brush can compound water quality issues. We are big fans of adding dense cover for bluegill and offshore cover for bass when lakes are being constructed. However, there is too much of a good thing. Leaving too much brush can release tannic acid. High levels of tannic acid decrease oxygen levels.
georgia pond management
Fish will soon be stocked so Melissa is checking the water quality as a bench mark.

Today’s lake only needed fifty tons so it was a quick job. The tonnage was a little overkill but liming at high rates will last longer. Other companies will suggest one or two tons to the acre. It will appear cheaper at first. However the catch is it needs to be done every year so the company makes more money on application fees. At our tonnage rates we lime lakes every three to five years.

Summer

As we head into the summer this is the time we lime the bulk of our lakes. We also lime in the winter. We are booking up quickly for the month of June and July so get in contact the office if you would like your lake limed.

 

South Alabama Aeration Installation for Cyanobacteria Prevention

vertex lake aeration

With cyanobacteria becoming more and more wide spread we are taking preventive steps for our clients. Lake aeration is a great way to keep water from becoming stagnant.

Why is Cyanobacteria Bad?

Cyanobacteria grows in stagnate and nutrient-rich waters. Cyanobacteria produce toxins that affect people and pets.  The most common and serious health effects are caused by drinking water containing the toxins or by ingestion during swimming or playing in contaminated water. Not all Cyanobacteria produce toxins but many do. Lakes near heavy agriculture are more vulnerable due to the amount of fertilizers used. South Florida has been the hot spot in the last few years with poor water management, heavy organic loading from agriculture, and development. With few treatment options prevention is the best treatment.

Installation

With days of rain in Georgia is was exciting to be installing a lake aeration system under sunshine and not worrying about getting a truck buried in mud. Today’s installation had two cabinets and twelve total bottom diffused aeration stations. With the heat of a Southern Alabama summer the lake owner wanted to protect his investment from Cyanobacteria and fish kills. He plans to push this fishery to the max with future lime application, fertilization program, and heavy fish stocking.

Located near Mobile, Alabama the lake had great Southern charm with plenty of live oaks.
This is a sample of what the bottom diffused stations look like. The black membrane has tiny holes in it that produce fine bubbles. The fine bubbles are what break up the layers that form in lakes.

The bottom diffused stations are easy to install. Vertex are so simple they don’t even require hose clamps or Teflon tape.

We always bury the lines so the landscapers don’t hit the lines and it also looks more aesthetic.

The last thing to do is deploy the units. Vertex creates a detailed map for us. The unites are all placed in specific areas based on depth.

After a few thousand meters of tubing the team successfully installed all the units. The lake owner was very pleased knowing his investment is being protected. If you would like to protect your investment give the office a call. Don’t let a family member get sick be the reason you get your lake worked on.

 

 

Mid-April Electrofishing Recap

The electrofishing team has been bouncing around middle and south Georgia for the first part of April. The team has been tackling many diverse fisheries from lakes less than two years old while others have run their course and need to be drained.

Georgia electrofishing
The weather was erratic at best. The weather fluctuated between down pours and gorgeous early spring skies.

Post-Spawn Conditions

The spawn was very flat this year. There wasn’t much of a buildup. With the amount of rain and unusual temperatures the bass spawned when the conditions were right. Many of the fish we shocked had fresh sores and flat bellies indicating the spawn has already happened. Some lakes had schools of bass fry with males guarding the school.

Georgia Electrofishing
A few pounds in the bass world makes a load of difference.
Georgia Electrofishing
Even after spawning this fish is still in great shape. Her relative weight was well over 100%.
Georgia Electrofishing
The crappie were moving up to spawn as well. This crappie was about 1.5 lbs. Crappie spawn before bass hence why their numbers can get out of control but, it seemed like this year the bass and crappie were spawning side by side.

Seasonal Growth

This time of year we get lots of calls about algae growth. With the warming water algae is starting to grow again. There are some species of algae that grow in specific temperatures but die in warmer or colder temperatures.

Growth this sever needs to be chemically treated.

Launching our shock boat in lakes with aquatic vegetation can be tricky. It’s critical that we clean our trailer so we don’t transfer vegetation from each lake.

When algae is this thick it makes fishing almost impossible. A topwater frog is about the only thing that works in when filamentous algae is this thick.

Wrapping the Week Up

With a long week week of electrofishing coming to an end the team saved the best lakes for last.

Georgia Electrofishing
These bass are small but they are what all sizes of bass should look like. We always tel people healthy bass should look like footballs. Often times when electrofishing we shock bass that look more like torpedoes which indicates unhealthy bass.
Georgia Electrofishing
We are always telling people to diversify their forage base. Bass evenly eating four different forages allows no one forage base to get depleted. This particular client has low bass numbers so a small amount of goldfish survived. This particular lake had great numbers of shad. The property owner was adamant about stocking another load of shad but electrofishing revealed he had plenty.

Bass harvest is a great tool to ensure fisheries remain in balance. With this lake being a quality bass fishery we only released bass that had relative weights greater than 95%. At the end of the day almost 70 lbs of bass were harvested.

After four days of electrofishing and being on the road the team heading back to Ball Ground. Electrofishing is all fun till the boat is hooked up and pointed home. The real work starts now with report writing. We are booked out till mid-May so if you have any interest in getting your lake shocked now is the time to get in contact with us.

 

Start of 2019 Electrofishing Season

Georgia Pond Management

The Start of 2019

With water temperatures creeping up to the magical 60 degree mark, the shock team has been on the move. The electrofishing team was recently in Cartersville, Georgia.  The client being serviced has an unconventional goal of wanting to grow large Redear sunfish. Redear sunfish feed primarily on mussels so they become very large but the growth takes a while. As of now, no fish food company has figured out a food that Redear will consume.

Texas Hunter Fish Feeder
The lake has a small creek that runs close by. The creek is a tributary to a major creek in the Cartersville area so it floods easy. All fish feeders are built up to keep them dry.

The Shock

The fish are staging in preparation for the spawn. All winter they have been in deep water seeking shelter from the weather. People ask us why we don’t perform lake audits year around and the reason comes back to the fish. In the winter and summer, fish seek deep water. Deep water is more stable than shallow water. Our electrofishing equipment has an effective range of 4-6ft so our catch rates wouldn’t be high. Summer time water temps can be stressful to fish while they are in the lake so shocking fish in the heat of the summer can be deadly.

gizzard shad in a pond.
With low bass density and a pond full of gizzard shad, it’s no wonder this pond produces huge bass. The gizzard shad are in the 6-11″ range which makes them perfect forage. We did remove some larger ones since they were too large even for the biggest bass. Gizzard shad in a pond environment get a bad rap. Many biologists cite gizzard shad lock up as a major issue since it can negatively effect juvenile recruitment. The reward of stocking gizzard shad is trophy bass. Threadfin shad, bluegill, and other forage are great, but to get to trophy status, bass need large forage. Certain states are known for growing big bass while others aren’t. Florida has golden shiners that exceed 8″, Texas has tilapia, and California has rainbow trout.

Till the Redear sunfish get big enough to catch there are still plenty of fish to put a bend in the rod.

With the full moon coming soon, the fish are starting the stage for the spawn. Since the population is small, we tag a large portion of shocked bass. Our previous catches from last years electrofishing survey have grown 2 lbs in a year, which is phenomenal. Well managed lakes with an established bass population average 1 lb of growth per year.

As the weather continues to warm, keep up with the AES shock team this spring. Spring is when the largest bass are shocked.

 

 

Ageing Bass

Ageing a bass is one of the best ways a biologist can gauge the health of a bass. In the Southeast we use the otolithes to determine age. In the North or where there are defined cold and warm seasons scales can be used to determine age. This is a quick guide on how otolithes are retrieved and aged.

Matt will split and sand the otoliths so that he can see through them. They are glued to a microscope slide so Matt can count the rings. This fish is five years old. It weighed 434 grams with a length of 13″. This is extremely poor growth.

Once age has been determined we can now implement strategies to improve the fishery.  Most lakes have never been managed so they are full of old, stunted bass. In most cases the best option is to drain the lake and start over. It is possible to get these bass healthy again but it may be too late. Bass have a lifespan of eight to ten years. If a bass is stunted at six years old then pouring $2,000 of bluegill in the lake is futile. During an electrosurvey we take otolith samples so call us today and get booked.

Fish Stocking Fun for Kids

Fish Stocking, Bluegill

Here at AES we love to introduce children to all aspects of fishery management from stocking of a forage base, to the importance of habitat and the thrill of catching a great fish.  We made a delivery of bluegill to one of clients extra special for the neighborhood kids.

 

The children eagerly awaited as buckets of bluegill were loaded from the truck and then taken to the pond.

Once taken to the pond they all watched intently as the bluegill were released.

Electrofishing Outside of the Southeast

Although the bulk of our business comes from Alabama, Georgia, and South Carolina we are more than capable to survey lakes outside of our home range. With the number of years Greg has been in the pond management industry he has forged a reputation of building the finest fisheries so naturally word has spread. The shock team makes a road trip to Arkansas, Louisiana, and Mississippi in late spring and another trip to Illinois in early summer. Shocking in Florida is an emerging area for us as well. There are many companies in Florida than manage vegetation but few provide fisheries services.

Even if you do not think you’re close to the home office give us a call. Many times we can complete fish population surveys on multiple ponds in an area to reduce the travel cost.

South Florida Exotics

Exotic plants and animals have been an issue in Florida for years. During our past shocking of Lake Parrish near Tampa, Florida we ran into huge schools of tilapia. Often they would be feeding on the surface in schools of over a hundred fish. We knew their numbers were high but our senior biologist found some startling images.

Notice all the holes along the rim of the cove. Those are all tilapia beds.
Prolific Spawners?

Tilapia are illegal to stock in Georgia but there is a lesson for pond owners. When stocking your pond know what you are getting. Purchase from a company or hatchery that has a good reputation in the industry. The guy your buddy met at QuickTrip around 2am my not be the best choice even if the price is right. Georgia DNR tickets are not cheap.

Electrofishing Season Is Here

Started this year’s electrofishing season in Palm City, FL. We had the pleasure of sampling twelve ponds for Piper’s Landing Yacht and Country Club which is an absolutely beautiful place. The fishery in these ponds have been neglected since their conception so the fish we sampled were not quite as beautiful as their surroundings. But now that we have a good data set on the fishery, we will get these ponds turned in the right condition.

Though we did not sample any trophy fish, we did sample a few species that you will probably only see in ponds that are in South Florida.

Also, we did hear some information from Lake Committee that unfortunately is not that uncommon. Many of these ponds were stocked last year with fry to help improve the forage base. Unfortunately these lakes are clear (i.e. not fertile) so when these fry were stocked they had no food to feed on once they used up their yolk sacs. This resulted in no survival of these fry which means a lot of money was wasted. So next time you want to improve your fishery whether it is fish stocking, electrofishing, etc., please make sure you use a reputable biologist.
