一、海洋渔业发展现况和问题 海洋渔业是我省第一大海洋产业,但自20世纪60年代始因无限制,高强度捕捞,以大、小黄鱼、曼氐无针乌贼、带鱼为主体的四大经济鱼类资源至70年代中期先后衰退。到80年代末,渔汛消失,出现了渔业资源从原始结构型向次生类型演化的重大转变。90年代后因采取了伏季休渔期措施,保护了幼带鱼,使带鱼资源数量增加,但群体显现了低龄化和鱼体小型化趋势,其生物学特征也显示种群衰退现象,而大、小黄鱼和无针乌贼资源仍未有恢复迹象。
First, the current situation and development of marine fisheries Marine fisheries is the largest marine industry in our province, but since the 1960s due to unrestricted, high-intensity fishing, large and small yellow croaker, Mulan needle-free cuttlefish, octopus as the main body Four major economic fish resources have declined by the mid-1970s. By the late 1980s, the disappearance of the fishing season led to a major shift in the evolution of the fishery resources from the original structural type to the secondary type. After the 1990s, due to the implementation of the summer fishing moratorium measures, juveniles were protected and the number of hairtail resources increased. However, the population showed the trend of younger age and smaller size of fish, and their biological characteristics also showed the phenomenon of population decline. However, large and small yellow croaker And needle-free squid resources have yet to recover.
