渤海湾是渤海三大海湾之一,位于渤海西部,北起河北省乐亭县大清河口,南到山东省黄河口,陆源有蓟运河、海河等多条河流注入,浅海的浮游动物和浮游植物丰富,海域初级生产力高,成为小黄鱼、梭鱼、鲅鱼、鲈鱼、鳀鱼、对虾、毛虾、毛蚶、牡蛎、脉红螺等重要经济渔业生物的产卵场、索饵场及重要洄游通道。同时渤海湾还是黄海东海经济鱼、虾、蟹类资源的发生地,对黄海乃至东海的渔业生产意义重大。一、渤海湾渔业资源现状近几年来,由于过度捕捞、填海造陆以及日趋严重的海洋污染,渔业生物的生存空间进一步压缩,渔业生物种类减
Bohai Bay is one of the three major bays in the Bohai Sea, located in the western Bohai Sea, north of Laoding County, Hebei Province, Daqing River mouth, south of the Yellow River estuary in Shandong Province, the source of the Jiyun River, Hai River and other rivers into the shallow sea zooplankton and plankton Rich plants, and high primary productivity in the sea. It has become a spawning ground, a feeding ground for important economic and fishery organisms such as small yellow croaker, mullet, bighead carp, perch, bighead carp, shrimp, shrimp, catfish, oyster, aisle. At the same time, the Bohai Bay is still the place where the Yellow Sea and East China Sea economic fish, shrimp and crab resources occur. The fishery production in the Yellow Sea and the East China Sea is of great significance. I. Status of Fishery Resources in Bohai Bay In recent years, the living space of fishery organisms has been further reduced due to overfishing, reclamation and land reclamation as well as the increasingly serious marine pollution. The fishery species
