Interpretive Summary:

Technical Abstract: We evaluated the use of fish meal derived from a locally abundant, non-native fish species – common carp Cyprinus carpio – with the objective of offsetting the cost of marine fish meal (MFM, ~$1,200/ton) in yellow perch Perca flavescens feed. Biochemical analyses of meals showed that crude protein and essential amino acids were similar between fish meals, but crude lipid was higher in the common carp meal (CCM). Three isocaloric [3.38 ± 0.04 kcal/g (mean ± SE)], isonitrogenous (29.7 ± 0.5%) experimental diets were formulated to contain 50%:0%, 25%:25%, or 0%:50% CCM:MFM. Yellow perch (mean weight = 18.1 ± 0.6) were randomly stocked (n = 7) into 12, 37-L glass aquaria (four replicates) for a 56-d trial. Fish fed 25%:25% CCM:MM exhibited the highest weight gain, while fish fed 50%:0% CCM:MM had statistically higher food conversion and protein efficiency ratios. No statistical differences were observed for relative weight or hepatosomatic indices across treatments. These results indicate that CCM may be used to partially offset the use of a traditional fish meal in yellow perch diets.
