Studies on the quatitative requirements of fish are numerous and have employed a range of methods. In the review, dose response dietary lysine requirements are shown to have considerable intraspecies variation that cannot be explained by the particular laboratory variables between experiments (dietary formulation, fish growth rate, statistical model, and response criteria). Alternatively, it is demonstrated that marginal lysine intake in dose-response experiments is utilized for liveweight gain (LG) with an equivalent efficiency (54.1 mg LG/mg lysine intake). Equivalent lysine utilization for LG means the lysine requirements of fish are not dissimilar when expressed relative to LG - and estimated to be 18.5 g lysine/kg LG.
