Cleveland (AP) -- An unusual fishing technique is demonstrating the improved quality of Cleveland's Cuyahoga River, which spurred an environmental movement after it caught fire 40 years ago.
The technique called electrofishing sends a shock through the water that briefly stuns fish, which are caught in nets, examined and returned to the river alive.
An outing last month found some two dozen species and no deformed or abnormal fish, a departure from the 1980s.
Cleveland's sewerage agency, which monitors river quality, counted more than 60 fish species in the river last year.
Officials attribute the rising fish numbers to better sewage treatment and reduced industrial pollution in the Lake Erie tributary.
