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?

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.

When is the best time to stock fish in my pond? | Pond & Lake Q&A

When is the best time to stock fish in my pond?

When is the best time to stock fish in my pond?
Jan – Raleigh, NC

Pond owners looking to replenish their fish populations this season should grab their buckets and nets; spring is here and it is the perfect time to stock your pond with new game fish.

Spring and fall are the best times to add new fish to your pond as the temperatures are not as harsh making it easier for you to transport your newcomers and acclimate them to their new home. You can still introduce fish into your pond during the summer months but you will want to take extra precautions to make sure you can quickly transport the fish to your pond and take a little extra time during the acclimation process.

Deciding how many fish to add to your pond will predominately depend on the surface area of the water body. You can take a look at a few examples of stocking rates on our website. You will want to stick to a ratio of 3 prey fish (sunfish, bluegill, or perch) to 1 predator fish (bass) when choosing species to promote a healthy and balance fish population. Click over to our Fish Stocking Blog for some more information.

You can purchase fish from your local fish hatchery or catch and transport fish from a friend’s pond. Wherever the source, inspect the fish for signs of illness or disease before adding them to your pond. Our local customers can take advantage of The Pond Guy semi-annual Fish Day which takes place on the 7th of May. Fish day is a great opportunity to meet with other pond owners, speak with the friendly and knowledgeable The Pond Guy staff, and browse our wide selection of pond products from Pond Dye to 24’ Windmills. Customers can place orders online or over the phone until May 7th which will be available for payment and pick-up on the 8th between 11 a.m. and 1 p.m. There will be a wide selection of both predator and prey fish available for purchase including Hybrid Bluegill, Perch, Catfish and Bass. Walk-ins are welcome but selection will be limited by availability.

Make sure there is adequate habitat for your smaller fish to hide, grow and reproduce. Weeds, grasses and other debris already in your pond will provide some cover but you can introduce man made habitats to protect your fish without dealing with weeds and plants. Check out our Fish Habitat blog for some more insight into creating comfortable living spaces for your fish.

Which Fish?

So you’ve seen some fish swimming beneath the surface of your pond. Maybe they’ve even taken a nibble or two at your toes while you are swimming. Regardless of how you use your pond you would still probably like to know what types of fish are swimming beneath the surface. For all of you curious pond guys and gals out there who want to be better acquainted with their fish we present to you a blog on getting to know your fish. While there are many fish in the sea, there tends to be a slightly small selection in your pond. Let’s review the characteristics of some of the most common:

Bluegill

Bluegill / Hybrid Bluegill – Bluegill are one of the most common types of game fish introduced into lakes and backyard ponds. The body of a Bluegill is deep, robust, and cichlid-like. The mouth is small and the front of the dorsal fin is spiny. Bluegill are typically olive-green in color with five to seven dark vertical bands which fade as they approach the middle of the fish. Their belly is a creamy color and the pectoral and pelvic fins are often pigmented with white. There is a black opercular spot just behind the top of the gill and another on the back of the dorsal fin. The typical Bluegill will grow to a maximum of 10” in length and weigh in at around 1 pound, the largest caught weighing just under 5 pounds. Bluegill are a relatively hardy fish that thrive in water temperatures ranging from 39 to 72 degrees, feeding off of vegetation, insects and worms. Bluegill will spawn in water temperatures between 67 to 80 degrees in saucer shaped nests located in the sandy or gravel covered shallow areas of water. While people enjoy fishing and eating Bluegill they are also great food source for larger predator fish like Bass.

Bass

Bass – The Largemouth Bass is considered to be one of the most prized game fish in North America. Largemouth Bass are similar to the spotted bass and small-mouth bass but can be distinguished by the deep curvature of its dorsal fin and an upper jaw that extends past its eye. They are a rather slender and streamlined fish with colors that range from dark green on top, silvery green to yellow flanks, to a yellowish-white belly. Their sides are commonly accented with a dark and irregular strip. The average Bass will grow to around 16” in length and weigh in at or below 10 pounds with the worlds largest weighing a little over 22 pounds. Largemouth Bass are best suited for temperate or warmer water flourishing in temperatures around 80 degrees. Though tolerant of turbid water, Largemouth Bass favor clear water, sandy shallows, and abundant rooted aquatic weeds or slow moving rivers and streams with soft bottoms. Many species of pondweeds, water lilies, coontail, elodea, cattails, and bulrushes provide excellent cover. It has a widely varied diet that emphasizes on bluegill, minnows and other small fish as well as frogs and smaller animals like birds or young muskrats. Its predatory nature helps to keep bluegill from overpopulating. Bass spawn in early May and into June in firm sandy areas 2’ to 6’ deep when water temps are in the 60 degree range.

Perch

Perch – While they don’t grow large enough to be considered a prize game fish, the Yellow Perch is most sought after for its excellent table fare. Yellow Perch have bright yellow or yellow/green oval shaped bodies with a back ranging from a bright green to a golden brown. They are accented by seven dark, tapering, vertical bars, running from their back down to their grayish belly. Yellow Perch range from 6 to 12 inches in length and weigh in between 6 to 16 ounces with the largest catch weighing 4 pounds 3 ounces. Perch prefer cool clear water and should be stocked in lakes where the water temperatures remain below 80 degrees year-round. Yellow perch feed on zooplankton, insects, snails, and other small fish and are considered a prey fish rather than a predator. Yellow Perch become sexually mature at 5 to 7 inches and spawn in the early Spring when the water temperatures are between 45 to 55 degrees. The yellow perch makes an excellent forage fish for cool-water predators such as walleye, smallmouth bass, and northern pike.

Catfish

Catfish – Channel Catfish are growing in popularity among sport fishermen due to its large size, hard fighting ability, and tasty flesh. Catfish are characterized by scale-less skin and barbells, better known as whiskers, about their mouth. Channel Catfish can be distinguished from other catfish by the presence of dark spots on its body and a deeply forked tail. Channel Catfish have awesome growth potential reaching lengths of 4 feet, the world record catch in South Carolina weighing in at 58 pounds. Channel Catfish prefer clear slow moving water but can also tolerate muddy water. Channel Catfish are scavengers and will eat just about anything it can find including live fish and game fish food. They are sensitive to light and will typically reside at the bottom of ponds and lakes. Channel Catfish usually become sexually mature when they reach at least 11” but do not generally reproduce in ponds due to the absence of an adequate spawning structure. A suitable structure can be installed by placing buckets or drain tile in depths of 3 to 4 feet of water along the pond bottom. They tend to spawn from May to July when water temperatures reach 75 degrees.

Walleye

Walleye – One of the most popular game fish in North America, the Walleye is second only to the Largemouth Bass. While it is not the most spectacular fighter, Walleye are quite tasty on the table. Walleye sport an elongated torpedo shaped body with highly variable coloring. Their bodies can range from olive green to brown to yellowish gold often marked with brassy flecks. They have no distinct markings or bars but instead an overall mottling of brown or black and a white belly. Walleye grow to be anywhere from 13” to 25” in length and weigh in between 13 and 22 pounds. The maximum recorded Walleye measured 42 inches in length and weighed 25 pounds. Walleye are considered a cool water fish preferring warmer water than Trout but cooler water than Bass and Bluegill. They enjoy water bodies with sand or gravel bottoms near vegetation though they don’t reside within it. Walleye have a special reflective layer of pigment in their eyes to help increase visibility in their favored dark and turbid waters. Yellow Perch, Whitefish and minnows are the food of choice for Walleye but they will also eat insects, frogs and small mammals. Walleye will spawn in early Spring when water temperatures are around 42 to 50 degrees. They tend to choose locations with rocky or gravel coated substrate in 1’ to 6’ depths where moving water is present. Neither parent cares for their eggs in any way.

Crappie

Crappie – Another popular sunfish behind the Bluegill, the Crappie is considered an excellent game fish when taken on light tackle and its flaky white flesh is considered very tasty. Crappie are similar in body shape to other sunfish but can be differentiated by connected dorsal fins that lack a notch and contain seven or eight spines. They also have a large anal fin consisting of 6 spines that is nearly as large as their dorsal fin. Their bodies range from dark olive or brown to a metallic green with a silver or blue cast with black mottling throughout. Crappie grow close to a foot in length and can weigh between 2 to 4 pounds. The largest Crappie caught weighed in at just over 5 pounds. Crappie prefer clear water with plenty of aquatic vegetation and mucky or sandy bottoms. They are highly intolerant of turbid water. Crappie eat insects and their larva as a primary food source but will also eat small fish and minnows as well. Like Bluegill, Crappie nest in sandy areas or places with fine gravel in depths of 3 to 8 feet of water. They typically spawn in May to June when water temperatures are within the 58 to 64 degree range.

Trout

Trout – One of the largest of the freshwater fish, it is endowed with a flesh of superb eating quality and is eagerly sought by commercial, sport, and subsistence fishermen. Trout typically grow to be around 27” in length and weight between 3 to 9 pounds but are known to grow to lengths exceeding 4’ and weigh over 100 pounds. The largest on record weighs 102 pounds and measures 49.6 inches in length. Lake Trout are the least colorful of all Trout with a light green, grey, brown or blackish torpedo shaped body covered with irregular lighter colored spots. Lake Trout sport a deeply forked tail and reddish-orange pectoral, pelvic and anal fins. Lake Trout are truly a cold water fish preferring water temperatures around 50 degrees. Most anglers fish for Trout in the cooler early seasons via fly or spin fishing and have to resort to long lines and heavy lures in the warmer months as the fish retreat to cooler waters. Lake Trout feed mostly off of other fish, insects and small mammals. It takes around eight years for Lake Trout to sexually mature, meaning heavy fishing demand can dramatically deplete the Trout population. They do not build nests or beds by simply scatter eggs among large cobble or boulder substrates in depths of up to 40’ in late autumn.

You may have a harder time finding Trout or Bass in your pond in comparison to Bluegill as they tend to be a bit less social. You can take inventory of the fish in your pond by trying to fish them out or by using a Fish Trap. When stocking or manipulating your fish population be sure to provide adequate habitat for smaller prey fish to hide from predators and grow. You can achieve this by installing Fish Attractor Spheres or by providing aquatic plants. Take a look at our Pond Stocking Blog and Fish Habitat Blog to learn more about predator/prey ratios and implementing habitat.

Where’s The Fish?
Both fishing enthusiasts and pond hobbyists alike can appreciate the presence of a healthy fish population in their pond. While they are fun to catch and entertaining to watch, they also help maintain a balanced backyard ecosystem. As is true with most aspects of your pond, the key to maintaining an enjoyable environment is balance. When stocking your pond, you will want to add a combination of both predator (largemouth bass for example) and prey fish (bluegill or perch). Your predator fish won’t fare too well without prey fish on their menu. If you stock your pond with prey fish only, there will be few factors regulating their population which can lead to an uncomfortably high fish population. When stocking your pond, aim for a 3:1 prey to predator ratio to ensure your predator fish have a reasonable meal selection. Maintaining a clean pond with plenty of aeration will promote a robust and healthy fish selection. Most man-made ponds lack adequate habitats, so make sure you provide options like a Fish Attractor that provides a retreat for the smaller up-and-coming fish.

What’s the best ratio of predator to prey fish to keep the population growth steady? – Pond & Lake Q & A

3 Prey Fish to every 1 Predator Fish.

Pond & Lake Q & A

Q: I’m thinking of stocking my farm pond with fish. What’s the best ratio of predator to prey fish to keep the population growth steady? – Hoyt in Florida

A: When stocking your farm pond with fish, it’s always a good idea to keep in mind the ratio of predator to prey fish. If you’re an angler, you want those trophy fish to grow healthy and strong, and the only way to do that is to provide prey fish, like perch, hybrid bluegill or sunfish, for food.

The rule of thumb that we recommend is 3 prey fish to every 1 predator fish. So for instance, if you toss in 10 large-mouth bass or walleye, you’ll want to include at least 30 perch or bluegill to keep the predator fish healthy and their bellies full. When you first stock your farm pond, however, we recommend you add some fathead minnows to feed the predator fish while the prey fish get established. You may also want to feed the fish with a pellet food, like The Pond Guy® Game Fish Grower Fish Food and use an automated feeder to make feeding easy.

To keep the population of both predator and prey fish healthy, make sure your water is well aerated, too. If you don’t already have an air diffuser or aeration system set up in your pond, now is a good time to add one. When you introduce new fish to a pond or lake, they’ll be adding waste – something that can cause an algae bloom or pH shift and possible a fish kill. An aeration system will decrease toxic gases, increase the amount of dissolved oxygen in the water, and prevent harmful stratification from occurring.

Once your population is established, you can enjoy the many reasons why you wanted to stock your pond in the first place – like fishing! A pond stocked with bass and walleye also keeps the frog and leech populations under control, too.

What’s the best way to acclimate new fish to my pond? – Pond & Lake Q & A

Float for 30 minutes.

Pond & Lake Q & A

Q: What’s the best way to acclimate new fish to my pond? – Lafayette in Maryland

A: So, you’ve been to the fish farm, picked out your fingerlings, brought them home, and now they’re sitting in plastic bags or tubs waiting to dive into your farm pond. Unfortunately, you can’t just pour them in. In order for these little fish to survive and thrive, you’ll want to slowly acclimate them to your pond’s water and its temperature.

Here are some tips to make it easy:

  • Oxygenate: When you pick up your fish, most farms will pack your fish in plastic bags with water and oxygen; the fish will be fine for several hours. But if you transported your fish in barrels, keep in mind that they will quickly run out of oxygen unless supplemented with an air stone or air diffuser, like the PondAir™ 2 Aeration Kit.
  • Float for 30 minutes: The most widely used method of acclimating your fish to the pond is to float the unopened bag in the pond for about a half hour. This allows a gradual change in the water temperature until the water inside is the same as the water outside, at which point you can open the bag and release the fish into the pond.
  • Just add water: If you transported your fish in barrels or containers, use a bucket to add water from the pond to the barrel. This will gradually change the temperature and will provide some additional oxygen for the fish. Check your water temperature with a fish-safe thermometer, and once it has stabilized, pour your fish into the lake.

Remember, take it slow: Patience is critical when acclimating your fish to the pond’s new water temperature. Rapid changes in temperature may weaken the immune systems of your fish and make them prone to infection or – worst case – cause the fish to die immediately.
