Fish Species

It is important to know something about the prefered habitat of the fish you choose to raise in your pond. Species differ in their requirements for feeding, growing, reproducing and surviving. Oxygen or temperature requirements are just two examples. Other species than those described below may be available. Call 1-800-442-6648 for current availability and pricing.

Due to the stress of catching and handling fish, Aquatic Biologists, Inc does not keep a ready supply of fish available for immediate pickup. All fish must be ordered in advance. There is a $100.00 minimum order requirement. Fish availability varies throughout the year. Deposit may be required.

Fathead Minnow

Fathead minnowFathead Minnows are the most important fish in any management program. The Fathead Minnow is a plankton feeder, but it will also feed very actively on mosquito larva and on commercial feed. This fish spawns from the spring until late summer on the underside of nearly any material near the shore. Reproduction can be improved by placing structure in 1 to 3 feet of water. We recommend stocking about 100 - 150 pounds per surface acre in most water bodies. This is our #1 selling fish species.

Hybrid Bluegill

BluegillHybrid bluegills are a poplular choice when the objective is to produce large bluegill or to provide fishing for children or impatient anglers. Hybrid Bluegills are a cross between a male Bluegill and a female Green Sunfish. Hybrid Bluegills are voracious feeder, depending mostly on insects, zooplankton and very small fish. The Hybrid Bluegill accepts commercial feeds readily, but unlike its parent species continues to feed during much colder water temperatures, resulting in faster growth. Because of this, the Hybrid Bluegill will attain a weight of 2 to 3 pounds at maturity. Generally, we recommend 500 Hybrid Bluegill per acre in ponds.

Largemouth Bass

Large Mouth Black BassOne of the most sought after fish by anglers, the Largemouth Bass is very well suited for stocking in most ponds, provided adequate food and structure is available. Largemouth bass prefer quiet, clear waters with abundant vegetation and cover (Iguchi and Matsuura, 2004). More specifically, they prefer shallow water that is usually no deeper than 2.5 meters, but they sometimes occupy deeper regions. Fish, crayfish, frogs, and large insects make up their diet. The Largemouth Bass is commonly used to help control populations of panfish. Normal stocking rates are 25 Largemouth Bass per acre.

Smallmouth Bass

Small Mouth BassSometimes called a "bronzeback" for its brassy brown hue, the smallmouth is one of the strongest fish for its weight. Although this species is very popular with anglers, it is not always the best choice for shallow lakes or ponds. Smallmouth Bass require cool water temperatures for good growth, and normally have a hard time competing for food with the more aggressive Largemouth Bass. Smallmouth Bass prefer gravel or rubble substrate, boulders, some shade and cover, along with deep pools for stream environments along with a strong forage base. If there are no Largemouth Bass, you can usually stock approximately 25 per acre

Rainbow Trout

Rainbow TroutThis is a great fish to stock if you plan on ice fishing. One of the best fish to use when stocking your pond this fish produces an acrobatic show when hooked that is sure to entertain - they can easily leap into the air three or four times their body length. Rainbow Trout should only be stocked in ponds that are consistently below 70°F throughout the year. Sustained temperatures over 72°F will prove fatal. Rainbow Trout are strong feeders, so plan on stocking minnows or feeding 40% protein fish pellets if you do not have a large forage base. Rainbows can live in your pond for about 6 years.
We recommend stocking about 100 per Surface Acre. Rates upwards of 500 Rainbows can be stocked under certain conditions. Ask our biologists how many your pond can support prior to stocking. Brook and Brown trout are also available! Trout are very succeptable to copper algaecide and herbicide treatments.

Walleye

WalleyeThis fish generally prefers large, deep, cool open water areas with rocky shoals and inlet streams. However, if conditions are right, a certain amount can be maintained in smaller lakes and ponds. Walleye are bottom dwellers during daytime hours, so lakes and ponds with stagnant summertime bottom water do not provide good habitat. In addition, they are among the first to die during low oxygen conditions, so pond owners considering stocking Walleye should think of installing an Aeration System (see aeration section). Stocking densities vary greatly. Unlike trout, walleyes will not eat artificial foods. There must be a good supply of natural food (plankton, insect larvae, crayfish or minnows, bass, perch, and to a certain extent Bluegills, so a strong forage base is necessary. Generally, we recommend stocking about 20 - 25 per Surface Acre.

Black Crappie

Black CrappieThe Black Crappie option is the most complicated of pond stocking combinations in small ponds due to their ability to reproduce rapidly and overpopulate. Successful crappie ponds are greater than 5 acres with abundant habitat (brush piles) and numerous small (less than 1 pound) largemouth bass. Many people have had success with Black Crappie, mainly because no spawning occurred. Small crappie eat a variety of food, such as zooplankton, insect larvae, snails, and leech, but adult Black Crappie feed mainly on small fish. If you would like to stock Black Crappie, we recommend about 100-200 per Surface Acre. In order to successfully stock this species the pond most already have a strong predator fishery. This predator fishery must be maintatined.

Yellow Perch

Yellow PerchSome say the yellow perch is he best eating of all fresh water fish, but unfortunately its pond reputation does not match this. Being a very prolific fish with few spawning substrate requirements, perch can cause serious stunting problems in nearly any lake or pond. Yellow perch provides good forage for most predator fish, especially walleye. Yellow Perch consume a wide variety of food items, but fish do not become a major component of their diet until after reaching 7" in size. We recommend stocking 150-300 per Surface Acre in ponds with Walleye as the primary game fish.Northern Pike

Northern Pike

The Northern Pike is one of the largest game fish feeding continuously throughout the day and year. They can eat fish up to 18" long, ducks and even fully-grown Muskrats. Because of their territoriality and heavy feeding, only 2-4 per Surface Acre should be stocked to control other fish populations.

Muskellunge

MuskyMuskies are closely related to Northern Pike preferring large lakes with both deep and shallow basins. Muskellunge can have a positive effect in waters over populated with perch, bass, and to a very limited extent on Bluegill. Stock 1-2 per Surface Acre in suitable waters void of Northern Pike.

 

Notices

In order to stock or contain fish in Wisconsin, you must have an approved WI DNR fish stocking permit or a Type 1 WDATCP Fish Farm License (Exits Site). To renew your current Type 1 Fish Farm License click here.

Health Certificate

Since January 2002, a Fish Health Certificate (FHC) has been required for all fish stocked in Wisconsin, including private ponds. All fish available through ABI have undergone extensive testing to obtain this Health Certificate as required by law. Due to the length of time it takes to get each batch of fish health certified ABI requests all fish stocking orders to be placed 30 days prior to stocking.
