About 50 sterile grass carp with trackers were added to Candlewood Lake Wednesday morning, making it the first program of its kind in Connecticut. Each carp has a transmitter that was surgically inserted into the fish?'s stomach and an antenna several inches long coming out of its side. Using a unique radio frequency, scientists can track each fish to see how it moves throughout the lake and what factors contribute to these movements, including proximity to the Eurasian watermilfoil.
