Any experience with 350 or 500 gallon tank fish farming as a hobby?

Question

Perhaps a school could do this for enough food for a fundraiser. My wife's school has a small aquarium, but after many jokes on eating the contents...hmmm gets a person thinkin'

Answer 1

Not yet, though we are serriously concidering it.  We have a large pond (about 1/4 of an acre) which is stocked with fish.  I'm hoping Mike will answer this question, because he has awsome links to auqaculture sites.

Answer 2

Don't know about something that small, but commercial salt-water fish farming is going on at locations entirely separated from the sea. The filtration process to remove fish wastes is extremely complicated, uses enzymes in addition to physical filtration. A unit designed to produce 80 tons of fish per year is running near me in Korea, fully a mile from the sea (they trucked in sea water to get started). They hope to sell several species of fish to the Japanese market. Seaweed is in there, too, I think, though it's not for selling. The owner said he feels sure the project could be scaled down to about a quarter the size of this project, to fit into the model of family business. He said a husband-wife team could maintain a small facility.

Answer 3

It is quite profitable and rather easy to do.  Here is a link with more information about how to do it and purchasing:

As you can see, it is currently out of stock.  Given the popularity, no surprise there!

Good luck!

Answer 4

I'm 55 and their must be some kinda money to be made because I've over the years heard a lot of people consider doing fish farming on the scale you have suggested.
