This link has some controversial statements about numbers of HSB per acre and weight gain per pound of food.
http://www.vet.upenn.edu/schoolresources/communications/publications/bellwether/44/fishfarm.html They say:
The studies at New Bolton Center and in Philadelphia should tell. One thing the researchers do know, compared to chicken, fish are more efficient in converting feed into market weight. It takes a 0.97 lbs. of fish food to yield one pound of fish. Theoretically a farmer could raise 4,000 fish per acre of pond and could earn between $6,000-$10,000 if all goes well. If the cost of closed system fish farming can be brought down, a producer then could look at a similar profit.
I could find no followup even though this was written in the winter 1999
This is the magazine archive links
http://www.vet.upenn.edu/bellwether/archives.shtml Has anyone ever heard of numbers like 4000 hsb per acre and 1# weight gain per .97 pound of food?
