Sounds similar to some of the trout growout programs that are going on in our area. Lots of fish and little tank (compartively speaking), lots of them I've seen end up with issues. I haven't jumped on board at this point, as I don't have the time or student interest.
Lots of fish is right! I end up doing different experiments on most the eggs testing teratogens and toxins. I still usually end up with more than I want and keep the tank from getting overcrowded by feeding the aelvin to other fish until I have a good balance. The rest get stocked locally and keep my annal ice fishing tourney for Kokanee up an running. I want to raise arctic grayling but still waiting on permits.
