The results showed that there were many coastal and epibenthile species, dominate fishes and crabs with significant monthly variation in composition, in the by-catch of shrimp beam trawls in waters surrounding Naozhou Island had. The average ratio of by-catch to shrimp was found to be 6.83:1 in weight and 2.5:1 in value, indicating that relatively high percentage of by-catch and less by-catch discards were the main problems in shrimp trawls.

结果表明：硇洲岛周围水域虾拖网副渔获种类多，主要为沿岸性底栖种类，组成结构存在明显的月变化，其中蟹类和鱼类是影响副渔获组成结构和月变化的优势类群；副渔获海上抛弃率很低，兼捕现象严重是现阶段虾拖网的主要问题，副渔获与目标虾类的平均重量比为6.8：1，平均产值比为2.5：1。
