渤海西部的毛虾(Acetes chinensis)是渤海的重要水产资源之一。成为河北、天津、山东惠民、昌潍地区转网、樯张网等定置网具的主要捕捞对象。解放以来的三十多年里,其资源发生过很大变化,从产量看,分为三个变动时期,前后渔获量高,中间渔获量低,呈马鞍形。尤其引人注意的是,在渤海里近十多年来,除对虾进行人为保护外,其它多数经济鱼类因捕捞过度而衰退。唯独渤海西部毛虾资源仍处较稳定上升的趋势。上升的原因何在?有人认为保护对虾的同时,也保护了毛虾。那么保护对虾的措施是否完全适用于毛虾资源数量变
Acetes chinensis in the western Bohai Sea is one of the important aquatic resources in the Bohai Sea. Become Hebei, Tianjin, Shandong Huimin, Chang Wei area network transfer, and other network set Zhang net fishing with the main object. In the thirty years since the liberation, its resources have undergone great changes. Judging from the output, it is divided into three periods of change: the catch volume before and after the catchment is high, the catch in the middle is low, and the saddle shape is present. Particularly noteworthy is that in the Bohai Sea in the past decade or so, in addition to artificial protection of shrimp, most other economic fish recession due to overfishing. Only in the western Bohai Sea shrimp resources are still more stable and upward trend. The reason for the rise? Some people think that while protecting shrimp, but also protect the shrimp. Then the protection of shrimp measures are fully applicable to the amount of shrimp resources change
