Yellow Perch For Aquaponics

As the aquaponics industry continues to grow, it is important that we have a good understanding of the fish species. Not only the most common fish species such as Tilapia, Trout and Catfish but also the lesser known ones. The yellow perch (Perca flavescens) is a medium-sized fish native to North America. It has been successfully cultured in ponds and cages and there has been an increasing interest in its culture in recirculating aquaculture systems (RAS).

Introduction

Aquaponics is the cultivation of fish and vegetables in a recirculating system. The fish are kept in an aquarium, where they produce waste that is later used as fertilizer for the plants. This system can be used for both commercial and residential purposes, although it’s more common for hobbyists to set up their own small-scale systems at home.

The yellow perch (Perca flavescens) is a freshwater sport fish native to North America. It’s a popular choice among anglers due to its abundance and large size: adults can grow up to 20 inches long! They’re found throughout much of Canada and the United States—the only exception being the southeastern states where they have been introduced as an invasive species.

Pond selection

Pond selection is an important consideration when building your aquaponics system. You want to make sure that the pond is deep enough, long enough, and wide enough to house all of your fish comfortably.

The recommended minimum depth for a pond is 3 feet (1 meter). If you plan to grow fish in the pond then it should be at least 4 feet deep. This depth will allow for adequate filtration of ammonia from waste produced by the fish as well as provide enough water volume for proper oxygenation of water in colder months when dissolved oxygen levels are low due to lower temperatures (DO levels drop as temperature decreases).

Ponds also need ample surface area so that they can have good circulation of air throughout the body of water. The surface area needed depends on how many types of plants you grow; however, for ease of management we recommend keeping your aquaponics system below 1000 cubic meters/acre or 10% of your total available land area if gardening space isn’t limiting factor.

Pond preparation and spawning

You can prepare the pond in a variety of ways, but the most common method involves placing a layer of clay around the bottom and covering it with plastic mesh. The mesh will allow water to flow through but prevent any fish from escaping. You can also use PVC piping as an alternative to clay if you don’t have access to it.

Once your pond is ready for spawning, fill it with water and add some wheat bran (or other grain) so that the fish have something soft to lay their eggs on. In addition, make sure there are plenty of places for small fry to hide from predators like raccoons or ducks — these may include rocks or logs placed along one side of the pond near where you intend for eggs to be deposited by females. Once all this is done, wait until springtime when breeding season begins!

Once spawning occurs and eggs are falling off into your tank’s water column, use nets provided by manufacturers’ instructions—or whatever works best within your budget—to harvest them away from predators like bacteria which could kill off young fry before they reach maturity if left unchecked.”

Egg harvesting and incubation

Harvesting the eggs is the first step in creating new fish. We have found that a net can be used to catch the fish and then we remove them from their nest. This will result in the most productive harvest of eggs.

We incubated some of these eggs and found that they should be kept at a temperature around 70F (21C) for optimal results.

Larvae rearing and nursery

The larvae rearing and nursery is essential to the success of your aquaponics system. It is here that you can expect the egg casings to hatch, creating an environment where they will grow into fish. The size of the larvae rearing and nursery should be determined by several factors including:

• The number of fish you plan on raising in your system
• The amount of room available in your greenhouse or garden area
• How many times per year you intend to grow out new batches (if at all)

Fingering and stocking

Fingering and Stocking

If you’re thinking about keeping yellow perch in your aquaponics system, here are some things to consider:

• Initial stocking density is 10 fingerlings (3 g) per square foot of grow bed surface area.
• The growth rate is 30-40% of final weight per month at 70-74 degrees Fahrenheit.
• Final stocking density is one fingerling (0.5 g) for every two square feet of grow bed surface area.

Yellow Perch can be raised in aquaponic systems

Yellow Perch are a popular choice for aquaponics because they are hardy fish that can adapt to a variety of conditions. They are tolerant to extreme temperatures, which makes them more resistant to disease than other species. In addition, they grow quickly and can reach an average size of 3 pounds (1.4 kg) within just two years.

The yellow perch is native to the St Lawrence River system in Canada, but has spread across North America over time due to stocking programs in lakes and ponds across the continent.

There are many species of fish that can be raised in aquaponic systems. Yellow Perch is one such species. If you are considering an aquaponic system, the information covered in this article can help you make a decision on whether or not Yellow Perch is right for your system.
