The European pikeperch, Sander lucioperca (L.) is a valuable species in aquaculture, and its nutritious meat is highly regarded by consumers. The contents of indispensable dietary amino acids (IDAA) in pikeperch fillets is higher than in other fish species and exceed the adult recommended daily allowance of them. Increasingly, the fish meal and soya protein components of fish feed are being replaced with protein from brewer's yeast, Saccharomyces cerevisiae. The aim of this study was to determine the fatty acid profiles of juvenile pikeperch fed feeds supplemented with yeast extract and to determine the IDAA requirements of this species using the ideal protein method. It was demonstrated that supplementing feed with yeast extract did not have a significant impact on nutrient accumulation in the fish. Pikeperch requirements for exogenous amino acids is similar to that of rainbow trout at 26.2 g 100 g-1protein. Commercial feeds used in pikeperch culture contain sufficient quantities of essential amino acids.
