Abstract: | Shrimp beam trawl has become one of the main operations in the East China Sea. In November 2013, we took out a survey of the catch composition with shrimp beam trawl in the offshore waters of the Zhoushan fishing ground. The catch was sampled randomly in a shrimp beam trawl vessel. With the identification and analysis, the total species of catches were 36 kinds, including 16 kinds of fishes, 10 kinds of shrimps, 9 kinds of crabs and 1 kind of stomatopoda. Based on the result of weight analysis, shrimps accounted for 33.42 %, fishes accounted for 32.85%, crabs accounted for 29.05 %, stomatopoda accounted for 4.69%, Bycatches were mostly fishes and crabs. |
