PCBs IN HATCHERY TROUT 1998 – Tissue samples collected from four PFBC hatcheries (1 composite of 5 fish) Concern that some anglers and their families were eating large amounts of stocked trout Some reported catching and keeping 100 or more stocked trout Data showed variable concentrations of PCB 3 samples were not of concern 1 warranted a 1 meal/month advisory
