You may also face difficulties getting the fish to survive well depending on where you live and the climate you keep. I’ll go over each fish below and discuss why they may or may not be a good choice for your aquaponics system.

Goldfish

Goldfish

You may not think of a small goldfish as a vital element to an aquaponics system. But it’s actually one of the best fish for small aquaponics systems. You won’t be able to harvest the goldfish for food but they do well in small environment such as aqariums sold in department stores. Overfeeding goldfish will increase their waste which can boost the entire system as well.


Tilapia

Tilapia

Another type of fish that is best for small aquaponics systems is the Tilapia. Tilapia have been farmed for thousands of years. And they remain one of the best fish to use in an aquaponics system. It’s easy to breed, fast growing, and can withstand harsh living conditions. If you’re starting out with an aquaponics system using tilapia may be your best bet. They will require a bit more space however which may be a problem for micro systems.


Trout

Trout

For people who live in cooler climates trout may be a good choice for your fish. They can survive and thrive in 10 to 20 degrees Celcius water and have a very fast grow rate. Trout also have very high food conversion ratios as well. They are carnivorous so placing them with smaller fish likely means you’ll end up losing the smaller fish. Trout may not be the best choice for smaller aquaponics systems.


Carp

Carp

Although once a popular type of fish used in aquaponics systems the demand for carp has declined over the past few years. They are edible and have good survival rates in a host of different conditions but may be lower uses because of taste. Goldfish are actually a breed of carp although not edible.


Catfish

Catfish

Another one of the best fish for small aquaponics is the catfish. Although catfish don’t have scales they are edible and taste good. They are found on every continent in the world except Antartica. They have been farmed for many years and are fast growing and have an awesome food conversion ratio. For starting off they can do well in smaller environments. But you’ll want a larger system as time goes on for using catfish in your system.


Using Other Animals in Your Aquaponics System

There are other species that you can include in your aquaponic system as well. And they may be a better choice for micro systems. In fact, the best fish for small aquaponics may surprise you.
