Marine Forensics Program: Development of a Biochemical Method to Distinguish Wildfrom Cultured Fish. Final Report

摘要

The study reports the results of a two year cooperative research effort betweenthe National Marine Fisheries Service (NMFS), Charleston Laboratory's Marine Forensics Program, and the South Carolina Wildlife and Marine Resources Department (SCWMRD), to develop a biochemical method to distinguish wild fish from those that were 'farm-reared' (cultured) using the edible portion of the fish as the test material. The research effort was initiated because of concern by SCWMRD that a successful hybrid striped bass aquaculture industry might result in an increase in the illegal sale of wild striped bass and its hybrids from SC waters. Fatty acids from 633 wild fish and 68 cultured fish were analyzed during the two year study. Linoleic acid concentrations (weight percent) averaged 3.3 +
