- ... To determine the effects of feed processing method (extrusion or expansion followed by compression pelleting) on feed physicochemical characteristics, fecal stability, water quality, and growth performance in rainbow trout, three types of feed pellets (expanded sinking [EpS], extruded sinking [ExS], extruded floating [ExF]) were prepared, analyzed, and fed to juvenile rainbow trout (initial weight ...

- ... The level of the essential amino acid lysine is of concern in trout feed. The objective of this study was to investigate the response of different families of fish to lysine-deficient (LD) versus lysine-adequate (LA) soy protein-containing diets. For each treatment combination, there were 5 replicates. As expected, feed efficiency (P<0.0001) and thermal growth coefficient (TGC, P<0.0001) were impr ...

- ... Replacement of fish meal with plant products in aquafeeds results in the elimination of dietary compounds which may be important for optimal growth and physiology. A study was conducted to determine if supplementation with macrominerals and/or inositol would improve performance of rainbow trout (Oncorhynchus mykiss) fed a plant-based diet. Four iso-caloric and iso-nitrogenous diets (40 g kg)1 prot ...
