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.
