Abstract

This 125-day experiment evaluated the growth of adult rainbow trout (Oncorhynchus mykiss) fed one of three isonitrogenous and isocaloric diets (46% protein, 16% lipid). Fish meal was the primary pr...

Highlights

  • Plant-based proteins, such as soybeans (Glycine max), have been extensively researched as alternatives to dietary fish meal (Gatlin III et al, 2007; Li & Robinson, 2015; Nordrum, Bakke-McKellep, Krogdahl, & Buddington, 2000)

  • This study showed that bioprocessed soybean meal can replace almost all of the fish meal in the diet of rainbow trout

  • Feed was analyzed according to Association of Official Analytical Chemists (AOAC) (2009) method 2001.11 for protein, 2003.5 for crude lipid, and American Association of Cereal Chemists (AACC) (2000) method 08–03 for ash content

Summary

Introduction

Plant-based proteins, such as soybeans (Glycine max), have been extensively researched as alternatives to dietary fish meal (Gatlin III et al, 2007; Li & Robinson, 2015; Nordrum, Bakke-McKellep, Krogdahl, & Buddington, 2000). Alternative protein sources are needed due to the exponential growth of aquaculture without a corresponding increase in sources of fish meal, which is primarily made from small. Voorhees is a research biologist with the South Dakota Department of Game, Fish and Parks. She conducts aquaculture and fisheries research on numerous trout and salmon species. Barnes is the manager at McNenny State Fish Hatchery in South Dakota. He has a has a wide variety of research interests
