How Do I Balance My Fish Population?

How Do I Balance My Fish Population?

Diana – Aurora, OR

A balanced fish population is key for creating a healthy, thriving ecosystem. Getting a handle on your current pond inhabitants is a great 1st step to achieving balance.

Start by sampling the current fish population using a fish live trap or fishing pole to catch and record the number, size & species of fish in your pond. You may notice, for example, that you are catching a large number of small predator fish like bass but very few prey fish like bluegill, perch or sunfish. This could signal an unbalanced ratio of predator fish to prey fish.

After analyzing your catch, determine the types of fish that are needed to rebalance the population. The ideal stocking ratio is 3 prey fish to each predator. If you are experiencing an abundance of small predators then stock up on prey fish or vice versa if you are catching an excessive amount of small prey fish. As your pond begins to balance you should notice an overall increase in the size and health of your fish along with an even yield of both predators & prey when trapping or fishing.

It is important to provide adequate habitat for young fish to develop and grow before being consumed by larger established fish populations. Fish Attractor Spheres are an ideal addition to any pond with fish. Smaller fish can hide in the narrower spaces closer to the sphere, large fish can navigate only the outermost regions of the attractor and minnows can hide within the open holes at the end of each pvc “arm”.

When adding your new fish to the pond, try to introduce feeder minnows at one side to preoccupy predator fish while your new fish are being added at the other end of the pond. This will give them more time to acclimate to the pond and find a place to hide. Feeder minnows can be added each season as they reproduce quickly and provide a naturally replenishing food source for your large fish.

What Is A Hybrid Bluegill? Should I Put Them In My Pond? | Ponds & Lakes Q&A

What Is A Hybrid Bluegill? Should I Put Them In My Pond? What Is A Hybrid Bluegill? Should I Put Them In My Pond?

Stocking up on fish for your pond can be fun and exciting, but if you’re thinking of adding bluegill, knowing some of the key differences between hybrid and regular bluegill will help you maintain a balanced pond.

Regular bluegill can grow to be anywhere between six and ten inches, and are olive green with an orange underbelly. They have uniform blue-black markings on the gills and fins, hence the name bluegill. The issue with regular bluegill is they reproduce quickly and can take over a pond very fast if there is not a suitable predator fish population keeping them in check. We recommend stocking your pond with hybrid bluegill to help prevent overpopulation.

Hybrid bluegill are a cross between male bluegill and female sunfish, which result in an 80%-90% of the population being reproduced male. This slows down fast reproduction by keeping the female population to a minimum. Do to their hybrid nature, they can also be slightly larger and have a bit more coloration to them than regular bluegill.

Whenever stocking any type of bluegill, keeping the population in check is key. To do this you must have the correct ratio of predator fish such as bass or walleye. We recommend a 3 to 1 ratio between prey and predator. This means for every 3 prey, you need one predator. For example, if you stock 150 bluegill you will want approximately 50 bass.

When stocking your pond with bluegill, use hybrid bluegill. They are still great for fishing and with these fish attractors, you’ll have plenty of action!

Do I really need to feed my fish? – Pond & Lake Q & A

Do I really need to feed my fish?

Do I really need to feed my fish? Joe – Little Rock, AR

Come And Get It
Those of us pond guys and gals that own large farm ponds have been feeding our fish for ages. Over the years, some of us have pondered, “Do I really have to feed my fish?”

“Fish” Food Versus Fish Food
There are two ways to keep your fish well fed: properly stock your pond or use fish food. We suggest both.

Properly Stocking:
To properly balance your pond, you should stock the water body with 3 prey fish, like Perch or Bluegill, for every 1 predator fish, such as Bass. This will ensure that your predator fish will have a bountiful selection of prey, while still giving the prey fish a sporting chance to mature and reproduce. If you stock too many prey fish, you will experience a very small number of big predators and a ton of tiny pan prey fish. If you stock too many predators, you will end up with very small predators and only a few big prey. When your pond is properly stocked, your fish population tends to keep itself in check. We suggest starting out with 300 bluegills and 100 bass per acre. You can add some feeder minnows into the pond to provide a nice snack that will be able to replenish itself. However, it is not uncommon for the fish in your pond to make short work of the feeder minnows you add to the pond.

Fish Food Pellets:
So you feel your fish should have a little more selection than their regular diet of … well … each other? You can control what your fish are eating by feeding them quality fish food like Game Fish Grower. Foods that are high in protein and low in filler promote rapid fish growth and optimum overall size. Pellet feeding also provides an opportunity to turn feeding your fish into an opportunity to have some fun. Pellet training your fish takes some patience and persistence, and while it can be trying at times, it is truly enjoyable once you get it right. Try to establish a daily routine feeding time and place so your fish will begin to expect your pond side presence. Start by throwing some pellets in the water from a distance, waiting for the fish to venture to the water surface to take the food. Repeat this process until your fish willingly greet you at feeding time. As time progresses, you can close the distance between you and the pond’s edge. Avoid making sudden movements, as this will scare the fish and they will be more hesitant to approach you at feeding time. You can then begin placing your hand into the pond with a fist full of food, opening your hand slowly to release the pellets which will float to the surface. You may not have any takers the first few days you try this, but if you are patient, they will eventually figure out where this food is coming from. As they grow more comfortable to your hand being in the pond, they will start eating from it. If you do not have the time or desire to feed your fish by hand, you can place a feeder, like the a directional feeder, at the pond’s edge to release food at programmed intervals.

What’s On The Menu?
While your fish always eat the food you throw in the pond like they haven’t eaten in years, the truth is, if your pond is stocked properly, they really don’t need any outside assistance. On top of having other fish in the pond to eat, they will also eat bugs from the surface of the pond, leaches at the bottom, and basically anything else they can find in the water. Try to catch some of the fish in your pond each season and record how many of each type you are pulling out of the pond while inspecting them for healthy color, weight, and size. Occasionally checking up on your fish will decrease the frequency and severity of population issues, while making your pond an enjoyable addition to your home with fun activities for the entire family.
