A cooperative feeding demonstration was conducted in 2013 between USSEC and Titikaka Trout Co. in Lake Titicaca, Puno, Peru. The objective of the demonstration was to show the feasibility of using a U.S. manufactured soy protein concentrate (NutrivanceTM) to replace fishmeal in the diet for cage cultured rainbow trout Oncorhynchus mykiss. NutrivanceTM is a feed grade soy protein concentrate (SPC) with high protein and low oligosaccharide content and minimal soy anti-nutritional factors. Rainbow trout performance was compared with a NutrivanceTM SPC diet and a fishmeal based diet. Results yielded similar trout performance with the two diets. The demonstration confirmed that SPC can partially replace fishmeal in the diet for rainbow trout, and that NutrivanceTM SPC is an acceptable ingredient for use in trout diets, thereby providing an alternative to fishmeal for the Peruvian trout farming industry.
