渤海自然条件优越,是鱼虾聚集的天然优良渔场,进入七十年代,由于种种原因,渤海水产资源遭到不同程度的破坏,生态平衡发生变化,这是调整渔业内部结构,发展渔业生产的新课题,需要认真对待,以期达到最适产量和提高生产力及在最近期内尽可能多地把水产资源合理地综合地利用起来的目的。 Due to its natural conditions, the Bohai Sea is a natural and fine fishing ground where fish and shrimp gather. In the 1970s, due to various reasons, the fishery resources in the Bohai Sea were destroyed to varying degrees and the ecological balance changed. This is due to the adjustment of the internal structure of fisheries and the development of fishery production Issue, which needs to be taken seriously in order to achieve the optimum yield and productivity and to maximize the rational and comprehensive utilization of aquatic resources in the near future.
