I suppose that is a good question. I am focusing on species that are very hardy, can handle low DO, high dissolved solids. The idea is to use a basic farm pond as sort of a nursery from which i can harvest fingerlings/advanced fingerlings for my experiments with closed system biofloc grow out. I have grown tiliapia, shrimp, and crawfish but want to focus on local species that can over winter naturally here. I am also going to be growing brown bullhead. Basically if everyone else is trying to get rid of it. Lol. I was unsuccesful with channel catfish with biofloc, but it is common overseas with some of their catfish so hoping the Warmouth and Brown bullhead will work here. Unsure how it will all work out, haven't found much info on temperate biofloc. Indoor production is very controlled but trying to keep 90 degrees 365 per year is not practical for homestead sized production.
