Are Some Fish Species More Difficult To Keep In Your Pond Than Others? | Ponds & Lakes Q&A

Are Some Fish Species More Difficult To Keep In Your Pond Than Others?

Are Some Fish Species More Difficult To Keep In Your Pond Than Others?

Steve – Delaware, OH

Whether you are an avid fisherman, fish grower or a regular homeowner with a pond, many questions exist in regards to common fish like walleye, tilapia and trout. Depending on your location and pond type, these facts will help everyone get on the same page.

Walleye – Typically raised by avid fisherman and fish growers. They are a great game-fish and are highly palatable. Walleye usually reach an average length of 14 inches and are sensitive to light so they require deeper ponds with murky water or lots of shade. A water temperature of 65-75 degrees is preferabl. A deep water aeration unit helps oxygenate deeper ponds for walleye.

Tilapia – Very popular among fish growers all over the world and are known for their taste and nutritious value. They are generally difficult for homeowners to keep because they tend to dig up the bottom areas of ponds, fight with other fish and also require warmer temperatures to thrive – usually between 75-85 degrees. Tilapia are a fast growing fish, but temperatures below 68 degrees drastically slow their reproduction.

Trout – Trout are popular among anglers and put up a great fight. They are also common among fish growers, but not as popular as tilapia due to their somewhat boney flesh. They prefer clear, cool waters of 50-60 degrees that are highly oxygenated.

How Do I Balance My Fish Population? | Ponds & Lakes Q&A

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!

What Is A Winter Fish Kill & Why Do They Happen? | Ponds & Lakes Q&A

What Is A Winter Fish Kill & Why Do They Happen?I’ve heard the term “winter fish kill.” What is it and why does it happen?

Linda – Stockbridge, MI

A winter fish kill occurs when your pond or lake becomes uninhabitable for aquatic life and a large number of fish pass away. Winter is the most common time for a fish kill because the long, harsh conditions of the season deplete the oxygen content of the water.

Prolonged ice cover on your pond or lake seals off the water from the air and prevents oxygenation of the water. Ice and snow cover also prevent sunlight from reaching your pond plants. Pond plants normally produce extra oxygen for your pond via photosynthesis. Finally, decomposing organic matter in your pond releases toxic gases that can’t escape from under the ice.

Eventually the competition for the limited supply of oxygen in the pond becomes too great. The fish suffocate and a winter fish kill occurs.

The good news is that winter fish kills are preventable. There are many things you can do as a pond and lake owner to maintain proper oxygen levels in your pond. First and foremost, invest in a good Aeration System. Aeration is the process of circulating air through water and it’s critical for overall pond health.  A second option is to add beneficial bacteria products like MuckAway™ or PondClear™ to your pond or lake before the winter season. Beneficial bacteria digest accumulated decomposing organic matter in your pond and convert it to a harmless, odorless gas.

Should I put catfish in my pond? | Ponds & Lakes Q&A

Catfish are some of the most diverse fish on the planet, both in behavior and appearance, and inhabit just about every continent except Antarctica. They live in shallow, freshwater environments, which can make them ideal for pond life here in North America. We generally only recommend channel catfish for ponds since they are the most common, but it will largely depend on your pond type and temperature. Catfish generally prefer warmer water (60-70 degrees Fahrenheit) with little to no currents, and since they are bottom feeders, they are drawn to darker areas.

They are also known to make for good fishing, and in warm environments they can be easy to farm and/or eat, and are very tasty if cooked properly. Fisherman and pond owners alike can use these Porcupine® Fish Attractors to help improve fishing conditions and to provide an adequate habitat for Catfish to spawn and grow. In addition we also recommend using this Game Grower Fish Food to guarantee your fish have food and to increase their overall size.

Catfish have little effect on the predator-prey relationship in freshwater environments comparative to predators like bass or prey like bluegills. They also pose no threat to humans, unless you’re planning on doing any swimming in eastern Europe, where there have been rare instances of large catfish (the 6 foot, 200 pound kind) attacking humans. Their only relative drawback is that they tend to kick up a lot of bottom debris, which can lead to cloudy, murky pond water.

In the end, putting catfish in your pond comes down to personal preference, rather than something that should or should not be done. They are well suited for pond life and will have little (if any) negative impact on the ecosystem already in place. It also doesn’t hurt that they can be pretty good to eat and easy to farm.

Fish are survivors. And when the water starts getting cold, they head for deeper waters, where the chilling effects of winter air are less pronounced. Provided there’s adequate aeration, your fish will likely linger at the bottom throughout the colder months. As a result, they’ll be much less visible – but the odds are extremely good they’re doing just fine.

In order to ensure there’s sufficient oxygen for the winter, some people opt to keep their aeration systems active all year ‘round. At the very least, though, it’s important to maintain a vent hole when – or if – your pond ices over. The vent hole allows harmful decomposition gases to escape, allowing fish to winter safely. And because their metabolism slows during the winter months, a properly vented pond will likely have sufficient oxygen to ensure the survival of your fish until springtime.

Fish, it turns out, are extremely resilient. After wintering in the lower reaches of your pond, your fish will gradually return to the upper levels once water temperatures start to rise. In general, it’s probably a good sign when fish become less visible. If they’re struggling, it’s far more likely you’d see them at the edges of your pond. So while you might miss them, your invisible fish are probably doing just fine.

When water temperatures drop below 40 degrees Fahrenheit, game fish activity slows down significantly – and their appetites slow down too. At that point, they’re capable of finding plenty of food in their habitat, making it unnecessary to continue feeding.

In a chilly winter pond, game fish are perfectly happy to forage for their meals. During the down season, they snack lightly on pond plants and small organisms, gaining sufficient energy to weather the winter until feeding season resumes. Game fish, it seems, never lose their natural ability to find the food they need. They make the most of their senses of smell and sight to track down necessary nutrients, and do their part to keep their pond clean until it reopens in the spring.

But when spring comes, and water temperatures climb above 40 degrees, their appetites return with a vengeance. They’ll be looking to you for sustenance – and nothing gets their mouths watering more effectively than our Game Fish Grower Fish Food. Scientifically balanced to suit the nutritional needs of bass, bluegill, trout and perch, this superfood creates a strong, healthy fish population, and ensures that your stock is in great shape for fishing season.
