摘  要:
对东海中华管鞭虾的数量分布及其主要生物学特性进行了研究,结果表明:调查区该种的年平均渔获率为524g/h,以春季较高(839g/h),秋季次之,冬季最低。其分布海域主要在20~60m水深,即在沿岸低盐水和外海高盐水交汇的混合海区,适温范围10~25℃。适盐范围30~34。繁殖期6~10月,盛期8~10月,9月至翌年1月相继出现30~40mm的小虾,并逐月长大加入捕捞群体,成为翌年新的捕捞对象。为合理利用该资源,建议12月至翌年2月,在小虾出现高峰期时,加强保护措施,增加补充群体的资源数量,提高经济效益。

摘  要:
The study on the biomass distribution & the main biological characteristics of Solenocera crassicornis in East China Sea was carried out and the results showed that,in the surveyed water areas,its annual average landing volume was 542 g/h.The number hit 839 g/h in Spring,went down in Autumn and dropped to its valley in Winter.Its distributing areas were between 20-60 meter depth layers,that is,the conjunction areas of both coastal low-salinity water and pelagic high-salinity water.The shrimp could survive at a temperature ranging from 10 to 15 ℃ and at a salinity ranging from 30-34.It bred from June to October,with the period from August to October being the best spawning time.Small shrimps of 30-40 mm length were found from September to January next year,which soon became a part of fishing target.In order to make good use of the resources,such measures as to protect he small shrimp from December to February,when there is to be a large number of them,should be taken into our consideration.
