Report: Native fish species decline at Lake Tahoe  — Native fish
species have sharply declined at Lake Tahoe over the last 60
years, according to a report by a team of scientists headed by a
University of Nevada, Reno researcher.  The study found that 58
percent of 26 historic sample sites around the lake showed a
decline of native species or no native species at all.
Researchers attribute the decline to the introduction of
nonnative fish species and multiple stressors such as algae
growth and habitat alterations in the "nearshore" zone where
fish spawn and develop into adulthood.  "The numbers are
alarming ... The bad news is the decline in native species and
the proliferation of nonnative fish species," said UNR
limnologist Sudeep Chandra, who headed the research team.  In
its report, the team is calling on the Tahoe Regional Planning
Agency to establish and implement a management plan to protect
the nearshore zone habitat for native fish - an area heavily
affected by human disturbances.  Chandra wants the
