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

fish) Data variable
Advisories issued for some fall-stocked fish

5 samples of 8 fish, proportioned, 45 total,
random 1 hatchery at 1 meal/week 1 hatchery
at 1 meal/month (same one as in 1998)
