渤海总面积约一亿三千万亩,平均水深不足二十五米,是一个半封闭的内海,并且有黄河、海河,辽河等多条河流注入。水质肥沃,饵料丰富是多种鱼、虾蟹类,产卵洄游和索饵育肥的优良场所,因此渤海渔业资源非常丰富、特别有闻名世界的对虾,为我国出口换汇的重要水产品之一,也是渤海沿岸渔民赖以生存的重要支柱。但是近年来、由于捕涝能力的迅速发展,捕涝量超过了资源的再生能力,生态平衡遭到了破坏,水产品的质量和数量都大幅度下降,有些品种正在遭到破坏,如此下
With a total area of about 130 million mu and an average depth of less than 25 meters, the Bohai Sea is a semi-enclosed inland sea with a number of rivers such as the Yellow River, the Hai River and the Liao River. Due to its rich water quality and abundant food, it is an excellent place for many kinds of fish, shrimps and crabs, spawning migrations and bait fattening. Therefore, the fishery resources in Bohai are very rich. In particular, the world-renowned shrimp is one of the important aquatic products for export in China. It is also an important pillar for the survival of fishermen along the coast of Bohai Sea. However, in recent years, due to the rapid development of waterlogging abilities, the amount of waterlogging exceeds the regenerative capacity of resources, the ecological balance has been destroyed, the quality and quantity of aquatic products have dropped drastically, and some varieties are being destroyed.
