Eyewitnesses said it was the biggest fish ever caught at the lake.
The black carp (Mylopharyngodon piceus) is a species of cyprinid fish found in eastern Asia from the Pearl River basin in China to the Amur River. It can be also be found in the tributaries of these rivers in China and eastern Russia, as well as northern Vietnam.
The black carp grows to a length of up to three feet (1m), and over 70 pounds (32kg), generally feeding on snails and mussels.
Black carp, together with bighead, silver, and grass carps, make up the culturally important "four famous domestic fishes" used in polyculture in China for over a thousand years, and known as "Asian carps" in the United States. Black carp are not as widely distributed worldwide as the other three.
In China, black carp are the most highly esteemed and expensive foodfish among the "four domestic fishes" and, partly because of its diet and limited food supply, is the most scarce and expensive in the marketplace.
