Alternative Proteins for Trout Feeds

The Western Regional Aquaculture Center (WRAC) offers a

new publication, “Evaluating Ingredients for Aquafeeds:

Alternative Proteins for Trout Feeds.”

 

With the rapid rise in feed ingredient costs and the finite source of and growing demand for fish meal, alternative ingredients are necessary to minimize feed costs.

 

Collaborators from the western region examine alternative trout feeds in the technical report.

Based on the WRAC-funded project: “Cost-effective, alternative protein diets for rainbow trout that support optimal growth, health and product quality” with the objective to identify commercially available alternative ingredient combinations that meet the production needs of rainbow trout.

 

Evaluating Ingredients for Aquafeeds: Alternative Proteins for Trout Feeds

This technical report describes the evaluation of two experimental feeds with alternative ingredients and one commercial control feed during a production trial at a commercial trout facility in Idaho. In addition to the usual production metrics measured, product quality was evaluated using taste test panels, and a basic cost comparison analysis was conducted.

Feed costs account for a significant portion of operating expenses for trout producers, ranging from 40 to 60% of operating expenses. Producers therefore have a strong incentive to optimize feed efficiency.

This research and extension project was supported by Western Regional Aquaculture Center grant numbers 2006-38500-17048 and 2010-38500-21758 from the United States Department of Agriculture National Institute of Food and Agriculture.
