A cooperative feeding demonstration was conducted in 2013 by the U.S. Soybean Export Council (USSEC) and Amazon Fish Products S. A. in Ucayali, Peru. The objective of the demonstration was to evaluate the use of two new U.S. soybean products, Schillinger Genetics SG-3010 soybean meal and TechMix NutrivanceTM soy protein concentrate (SPC), to partially replace fishmeal in the diet for paiche Arapaima gigas. Both of these U.S. soy products have a high protein (>55%) and low oligosaccharide content with minimal soy anti-nutritional factors. Results of the feeding demonstration showed that SG-3010 soybean meal at an inclusion rate up to 41.9% and NutrivanceTM SPC at an inclusion rate up to 36.5% in the diet for paiche yielded fish production equivalent to that obtained with fishmeal-based commercial diets. Results indicate that both soy ingredients offer feed formulation options for the paiche industry in its effort to reduce dependence on fishmeal.
