No set methionine requirement for Pacific white shrimp is a major constraint to feed manufacturers accepting soy-based feed formulations. The objective of this research was to support a concerted effort to evaluate the efficacy of several amino acid supplements and attempt to quantify the methionine requirement. Shrimp are semi-continuous feeders and digest foodstuffs very quickly. There is no synchronous absorption of supplemented amino acids based on both absorption and clearance patterns of amino acids. Growth trials were conducted to evaluate the growth response to various methionine sources using a range of supplements.
