Overview and Summary
to a study just completed by the NY Department of
Environmental Conservation, declines in small mouth
bass and other warm water species in the eastern
basin of Lake Ontario is due to two factors. The
increase in double crested cormorants and an
decrease in alewives and change in distribution.
The study also found
that Cormorants are feeding on larger bass than
first thought. Greatly increased bass mortality in
the 1995 class has been detected in 1998 as three
year old fish. "If predation is unchecked, we
anticipate two more years of intense predation on
age-4 and age-5 fish will likely remove the
remainder of the 1995 class prior to the time they
become available to eastern basin bass anglers."
