An initial investigation into the inclusion of high protein distillers dried grain with solubles (HPDDG) in juvenile rainbow trout Oncorhynchus mykiss diets was conducted during a 36-day feeding trial. Four experimental diets containing either 10% or 20% HPDDG with supplemental amino acids, and either with or without phytase, were compared to a fish-meal-based, non-HPDDG, diet. There was no significant difference among any of the diets in total weight gain, percent weight gain, feed conversion ratio, or percent mortality. There was also no significant difference in length, weight, condition factor, hepatosomatic index, viscerosomatic index, or any fish health parameter in fishes …

Flavobacterium psychrophilum is a ubiquitous bacterium in the aquatic environment, particularly in freshwater [1]. As the etiological agent of bacterial coldwater disease, it is a serious fish pathogen causing substantial economic losses and rearing difficulties to both commercial and conservation aquaculture [2]. This review paper describes the epidemiology, clinical signs, prevention, and treatment of the fish diseases attributed to this pathogen, which are similar despite the different geographic labels. In addition, the basic biology of F. psychrophilum and the techniques required for successful bacterial culture, isolation, and identification are discussed.
