If thats the case they could just get fish out of the hatcherys that already exist. When the fish get to the terminal, they could give the tribes as many as they are allowed, then give some to the commercials... no nets needed. That would be way to simple however. What fun would it be if they knew exactly how many hatchery fish they got, and did not kill wild ones as well.. Seems like the best answer to me all around but it is way to logical to ever work.
