Feeding experiments were conducted to evaluate the growth performance, feed conversion efficiency, total food intake and heavy metal accumulation (Cd and Cu) in fingerling rockfish, Sebastes schlegeli, fed extruded pellets containing commercial diets supplemented with 0% (control) to 30% Squid Liver Pellet (SLP) for eight weeks. Growth performance did not differ significantly in any of the experimental groups, but total food intake increased in response to increased SLP content. Findings also suggested that diets supplemented with SLP promoted fish feeding. However, accumulation of Cd and Cu in the liver of fish was more apparent in experimental groups fed diets containing 20 or 30% SLP. These findings indicate that SLP should only be applied at levels of up to 10% in the diets of fingerling rockfish.
