I saved my Christmas tree. Can I use it for a fish habitat in my pond? | Ponds & Lakes Q&A

I saved my Christmas tree. Can I use it for a fish habitat in my pond?

Q: I saved my Christmas tree. Can I use it for a fish habitat in my pond?

Peter – Cedar Rapids, IA

A: Great question! Sure, after the holidays have come and gone, it makes complete sense to use your dried-up Christmas tree as a fish habitat. You’re benefitting the environment by repurposing the tree rather than sending it to the dump, and you’re saving money by providing your fish a free all-natural habitat.

Plus, your finned friends will love it. Though they probably won’t pile presents under a submerged Christmas tree, your fish can use it as a cozy place to hide from predators and a safe and effective spawning zone.

There are some drawbacks, however, to tossing a spent holiday tree in your lake or pond.

Because it is an organic object, a tree’s trunk, limbs and needles will break down and decompose over a long period of time. This all-natural process will contribute to the nutrient load in your lake’s water—and that means an increase in algae and weed growth.

Not only that, but the tree’s tight interwoven branches make a great hiding place from your fish hook, which means you’ll have a harder time catching them for dinner!

So rather than throw your Christmas tree into your lake or pond, you should use it as firewood to fuel a lakeside bonfire instead. And if you really want to give your fish a new habitat for Christmas, invest in one that befits the fish while keeping the pond clean, such as the Porcupine® Fish Attractor Spheres. When you outfit these 6-inch-diameter units with 26 lengths of ½-inch PVC pipe, they become ideal habitats that are effective without impeding fish catches or adding algae-loving nutrients to your water.

How Can I Keep My Pond & Fish Healthy With All Of This Hot Weather? | Ponds & Lakes Q&A

Q: How can I keep my pond & fish healthy with all of this hot weather?

Cheryl – Cheshire, OH

A: If you’re feeling the heat, there’s a good chance the game fish in your pond are feeling it, too. Not only will they sense the temperature increase in the water, but they’ll also be affected by a decreased amount of dissolved oxygen in their environment.

So what can you do to keep the fish in your lake or pond cool and comfortable? Check out these four expert-recommended tips:

1. Provide a Cool Habitat: Like humans and other land-dwellers, fish like a place to hide to get out of the sun. They’ll slip under the shade of plants, swim inside logs and take advantage of spots like the Porcupine® Fish Attractor Spheres, which encourage plant growth and give them a place to feel safe, shaded and protected.

2. Keep the Water Moving: When the water moves and circulates with an aeration system like an Airmax® Shallow Water Aeration System or an above-surface fountain like a Kasco Decorative Fountain, it allows for greater gas exchange at the water’s surface, expelling dangerous ammonia and taking in healthy oxygen. This provides more “breathable” space for your fish to swim deeper in the pond – where it’s cooler.

3. Rake Out Dead Debris: To cut back on the dangerous gasses being produced in your lake or pond, remove dead debris and decomposing plant matter with a Weed Cutter and Rake. Less debris in your lake means less gas is being produced.

4. Be Cautious of Water Treatments: Dead or dying organic materials can reduce oxygen levels quickly, so be cautious when using algaecides or herbicides to treat algae and other weeds. Rather than dosing your entire pond or lake, treat one section at a time, waiting a week or two before treating another area. This allows the fish to remain in the unaffected areas.

With a little planning and a some regular maintenance, you can keep your recreational pond or lake healthy no matter the temperatures. Your fish will thank you for it!

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?

Richard – Sheridan, IL

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!

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

Should I put catfish in my pond?
Steven – Middlebrook, VA

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.
