Abstract

Atlantic cod (Gadus morhua) is an emerging species for cold-water aquaculture in Europe. Currently, diets for cod are largely based upon fish meal and fish oil. The use of alternative feed ingredients is however expected and highly relevant. In this study we have been investigating how pre-slaughter starvation affect muscle quality attributes, measured as muscle pH, water-holding capacity (WHC) and shear force, of farmed Atlantic cod that have been fed diets containing vegetable proteins. One group of fish was starved for two weeks prior to slaughter and the other group was starved for three weeks. The starvation time influenced significantly the attributes muscle pH, WHC and shear force, which may indicate that pre-slaughter starvation could be used as a tool for modulating required quality attributes.
