Scientists are tracking 14 fish at Lake Tahoe to study their movements and try to prevent their species from spreading out across the lake and upsetting its delicate ecology.
Large mouth bass and bluegill typically are found in much warmer waters. Researchers believe they were introduced into Lake Tahoe by
people about 15 years ago.
If left unchecked, scientists said they could significantly threaten Tahoe's cold water fishery.
The scientists plan to track the fish through next winter.
If they find they're becoming overbearing in some areas, researchers say they can be electroshocked and removed to try to stem their numbers.
