TVA is enlisting the help of local anglers to conduct its annual fish survey, which
helps determine the number, age, and general health of black bass in reservoirs
throughout the Tennessee Valley. The 2001 survey is scheduled to begin in
March and last through early June.

The results of the survey, which uses a fish-sampling technique called catch
depletion, are used by state agencies to protect and improve sport fisheries.

Volunteers fish for one hour in selected coves that have been blocked off with a
net. Then TVA biologists use electrofishing equipment to catch, or deplete, the
remaining fish in the cove. In that process an electric current is used to
temporarily stun the fish so they float to the top. They're collected with nets,
counted, weighed, measured, and released unharmed outside the cove. The cove
returns to normal within hours after the net is removed.

To participate, call TVA at 256-386-2729 (Alabama) or 865-632-1721 (Tennessee),
or send an e-mail to tvainfo@tva.gov, attn. Ginger Seeber. Here's the schedule for
this year's survey:
