Vegetable based fish feed changes protein expression in muscle of rainbow trout (Oncorhynchus mykiss)

Abstract

Feed production for aquaculture of carnivore fish species relies heavily on protein and lipid from the limited resources of wild fish and other sea living organisms. Thus the development of alternative feeds replacing fish meal and oil with alternatives of e.g. vegetable origin is important for a sustainable production of fish from aquaculture (Glencross et al. 2007). Such a change in feed ingredients will affect the metabolic pathways in fish and during the last years genomic and proteomic techniques have contributed in obtaining a better understanding of the involved mechanisms (Panserat & Kaushik 2010; Martin et al. 2003; Vilhelmsson et al. 2004). A consequence of fish meal and fish oil replacement in the feed may also be a change of eating quality (Johnsen et al. 2011; Lesiow et al. 2009).KeywordsRainbow TroutPartial Less SquarePartial Less Square RegressionFish MealWild FishThese keywords were added by machine and not by the authors.
