I often get asked what kind of fish should be used in an Aquaponics system. Normally, my answer would depend on the climate the Aquaponics system is based. Lately, I've been modifying my answer because a common problem we all run into: cost.
When I say cost, I don’t just mean the actual dollar price for the fish or fry. We need to look at other factors such as food, energy costs, skill level etc. Jumping into a large Aquaponics system can put a nice dent in our wallets and the feeling of throwing away over one hundred dollars on fish because of a simple mistake can leave even an experienced Aquaponics gardener feeling low.
