摘要
本文对(石匈)洲岛周围水域墨吉对虾的移动、繁殖习性和幼、成虾的数量分布特点以及环境因子对幼、成虾数量的影响进行了分析。并估算出其生长和死亡的参数,应用单位补充量产量分析和体长股分析的方法进行资源评估。
Penaeus merguiensis is an important commercial shrimp in waterssurrounding Laozhou Island, where P. merguiensis has 44.8--69.6% on catchcomponent of shrimp species. Spawning season is January to June and its peakperiod is in April and May. The maturity of ovary cell is not unanimous. The ma-turity cell drain in batches. Two times of low salinity period and once of alow temperature period showed in a year. The quantitative fluctuation of juvenileshrimp has a close correlation with temperature and salinity in spawning season.Growth and mortality parameters were also estimated in this paper. Yield perrecruit and length-cohort, analysis have been used to make the stock assessment.
