Increasing
predation rates caused post-stocking
survival of brown trout to
decline:
–Walleyes
–Cormorants
–Recovery
of other predators.
THUNDER
BAY STUDY
The leading
hypothesis for the decline was that predation rates had increased on the
stocked trout.Predation increases
were caused by recovery of walleyes and other piscine predators and fish
eating birds.
