Hope I don't change the subject on this thread. But I really like the idea of adding rainbow trout during the cold months for two reasons! Trout are great for the plate during colder water temps that support them. Second, Just like the shad and tilapia that die off and make for easy pickings for predators in the winter when water temps drop. Any left over Trout make for easy pickings (high in protein to grow giant bass) during the warmest months. Just my $.02 Plus with supplemental feeding the trout can grow pretty big in a year, from what I've learned from the experts on this site.
