All fish farmers always want to be able to supply the right fingerlings to the fish fattening unit. By cooperating on a project run by the University of Göttingen, I have learned how to do this: the spawning season for trout can be influenced by artificial light. It is therefore possible under optimum conditions to strip the same spawning pair up to three times per year. Farmers thus obtain “summer eggs” and are independent of the season and the natural spawning period. With my help, you’ll achieve added profits for your business based on our research.
