Photo-period technology, increases trout production

In Mexico, the National Fisheries Institute (INAPESCA) has developed a technology that allows the reproduction of trout eggs aquaculture through out the year. Photo period is the alteration of light duration. By altering the length of time of an applied artificial light you can cue the breeding instinct to start by making the trout think it is Summer or stop it by making him think its Winter.
