Does the number of fish in the tank affect the growth as they get bigger? I would think it would with high fish densities, but I plan on keeping it to at least ten gallons per pound of fish. If I had more water per pound would I get better growth later on?
My goal is to see how big I can get them in four years on pellets alone.
Thanks for the help this forum is the best!
It's not fish growth you have to worry about with higher fish densities. It's reduced water quality which causes obvious problems. Specifically higher densities reduce oxygen levels and increase ammonia, nitrites, and nitrates. Most fish don't have a problem with nitrates but trout do.
I was told by some experts in growing out salmonids in an RAS, as long as I stay below 0.25 lbs. of trout per gallon I should not have any fin issues. I doubt I'll even get close to 0.25 lbs. per gallon with the trout, as with the price I get for them, I don't need to and to me 0.25 lbs per gallon is a lot of fish.
