growths on provo fish

During the fall spawn, the browns are rubbing the mucous layer off of their skin and also nicking their skin up while making their redds. No matter what stress level the browns are at, an intact skin with a good mucous layer is the best defense against saprolegnia. That's why we often see browns in this condition in the fall and early winter and hardly ever at other times of the year.
