Development and evaluation of starter diets and culture conditions for 3 subspecies of cutthroat trout and Gila trout

Our research is centered on enhancing the propagation and long-term survivability of cutthroat trout (Oncorhynchus clarki subspp.) and Gila trout (O. gilae gilae). Our aim is to empower fish cultivators and feed manufacturers with valuable insights that can be utilized to increase the yield and quality of these species.

Objectives

1. Determine the effect of feed texture and formulation on survival, growth, and quality of cutthroat and Gila trout. 
2. Determine the effect of water temperature on trout growth, survival, and quality when reared under laboratory conditions. 
3. Determine the effect of rearing density on cutthroat trout growth, survival, and quality. 
4. Conduct production-scale evaluations of the best diet × temperature × density combinations identified in the first three objectives. 
5. Develop outreach products to provide fish culturists and feed manufacturers with information on optimal growth temperatures, optimal rearing densities, and diet formulations for inland cutthroat trout subspecies
