AbstractEleven batches of European hake, Merluccius merluccius, caught in waters off Scotland, were analysed. The following mean values were obtained: water 79.04%, total nitrogen 2.96%, ash 1.31%, lipid 2.24%, non‐protein nitrogen 0.304%. There was a small effect of season on these values. The length/weight relationship, the condition factor, and the yields of various parts of the fish were also determined.
