Research Project:
DEVELOPMENT OF PLANT-BASED FEEDS FOR TROUT
Location: Aberdeen, Idaho
Project Number: 5366-21310-003-02
Project Type:
Specific Cooperative Agreement
Start Date: Sep 30, 2004
End Date: Jun 30, 2009
Objective:
The objective of this research is to develop and test plant-based trout feeds that reduce or eliminate the use of fish meal and fish oil, while maintaining superior fish performance.
Approach:
Potential alternate ingredients will be selected based upon nutrient and anti-nutrient profiles. Special emphasis will be selected based upon barley and oat cultivars, but any ingredient that has favorable profiles will be considered. Some marine oils and proteins maybe evaluated at low inclusion levels to enhance feed palatability and the final product fatty acid profile. Practical feed formulations, based on plant-derived will be used to evaluat vitamin premix formulations, and all feeds will be produced using manufacturing technology appropriate for that particular type of feed. Feeds for rapidly growing juvenile fish will be produced using cooking extrusion. Traditional methods, including growth performance and tissue saturation levels, will be used to determine optimal levels of micro-nutrients along with the development and evaluation of molecular expression assays. Documents SCA with U of Idaho-Hagerman.
