１９９９年１１月上旬，对长江黄州江段的鲤鱼进行了相对渔获量、种群结构和体内寄生蠕虫的调查。统计结果表明，鲤鱼只占总渔获量的７％，且９４％为当年的小幼体。鲤鱼的鳃上及消化道内只有三种蠕虫寄生。宿主感染这三种寄生蠕虫的感染率和感染强度均很小。据此提出保护、合理利用这一鱼类资源的几点建议。 In early November 1999, the relative catches, population structure and parasitic worms in the carp of Huangjiang section of the Yangtze River were investigated. The statistical results show that carp accounts for only 7% of the total catch, and 94% of the young hatchery of the year. There are only three types of helminth parasites in the carp’s gills and digestive tract. Host infection of these three parasitic worms infection rate and infection intensity are small. Accordingly, some suggestions on how to protect and rationally use this fish resource are put forward.
