You need fish for an aquaponics system. Aquaponics is the combination of aquaculture and hydroponics, aqua- and -ponics combined. Without fish you can't feed your plants naturally and you're just doing hydroponics.
Aquaponics is great. You get to grow your own produce and are raising fish at the same time. It's easier than having a traditional fish tank aquarium.
Fish for Aquaponics
Depending on whether you are doing aquaponics indoors or out has a lot to do with what type of fish species you pick. If outside you'll need to take into account your local fish supply and climate. Trout do great in cooler climates, while Barramundi prefers warmer climates.
Ask yourself these questions to determine the best aquaponics fish for you:
- Do you want to eat your fish?
- Do you want to harvest your fish seasonally or year-round?
- What fish is available in your area for you to buy fish stock?
One of the most popular fish used in aquaponics tanks is tilapia. Tilapia for aquaponics are truly ideal. They grow very fast to edible size. Even if the water conditions aren't ideal, this fish will still grow.
Catfish (edible, warm water, omnivore) – Channel catfish are the most aquaponics cultured fish in the United States. They grow quickly and have a good food conversion ratio.
Tilapia (edible, warm water, omnivore) – The second most cultured fish in the world. Tilapia is one of the most popular fish to use in an aquaponics system. They are easy to breed and fast growing. Tilapia taste great and can withstand poor water conditions.
Trout (edible, cool water, carnivore) – Trout grow quickly and taste great. Their food conversion ratio is very good.
