Carps are better, they grow fast and you may remove them for sale before it is too cold; in spite of their size.

Cat fishes is second choice, they may tolerate cooler temperatures than carps. They will need greater diet in terms of fats, to survive winter.

Answer 8

gold fish they die so fast the parents will race back to replace it before the kid finds out.

Catfish

Answer 10

Ask a local fish merchant what fish people will pay most for, and narrow it down to those you can grow.

I was fishing off the West coast of N America and south coast of Alaska we sold the bulk of our food to a Japanese packing ship, but would make runs into cities to sell species in local demand to get much higher prices.

It can be economical to feed a low value species to be used as food for a high priced. But demand does change and you need to repeatedly re-test the market demand, change to suit it.

Answer 11

If you live in a warmer climate the fastest growing and most profitable fish is the Tilapia. With a colder winter the Catfish is still the best fish to farm.

Answer 12

A trout farm comes to mind, however I am assuming you mean like tropical fish or ones you raise in a tank. I would say the Bettachris for tropical,  But for smaller freshwater fish, the best bet to make any money is to breed is the Discus.
