Idea to Reality: With the increasing demand for fishmeal in fish feeds causing increases in prices AURI client NutriVance wanted to explore alternative feed ingredients for use in aquaculture feeds to replace fishmeal and reduce the cost of fish production.

AURI’s Role: AURI assisted NutriVance in planning and executing feeding trials for this new, innovative product.

Outcomes: Results of this study demonstrate that NutriVance can be used to replace up to 25% of soybean meal and soy protein concentrate in a practical diet for rainbow trout juveniles without sacrificing growth performance, feed utilization and nutrient retention. Additionally, the study showed NutriVance removes anti-nutritional factors, reduces feed cost and improves uniform growth.
