摘 要 ：本文探讨了鹰爪虾黄渤海群系的种群结构特征。结果如下:1.种群体长范围、生殖群体为20—107mm;越冬群体为13—101mm。2.种群的年龄结构为3个年龄组,4个世代(0—3龄)。3.头胸甲长和体重关系W=0.002421L~(2.5173),r=+0.9961。4.雌、雄性比组成为1.35:1;性成熟的年龄一般为2龄虾。

Abstract:6778specimens were collected from the catches of Trachypenaeus curvirostris (Stimpson) in the Bohai and the mid and northein Huanghai Seas from February to December, 1984-1985. The major characteristics of population structure of the shrimp were described as follows:1. Body length composition ranges from 20-107mm in reproductive population and 13-101mm for wintering population. 2. Three phases up for the body length composition, which indicated groups by age and contained four may be summed cohorts (0 -3 ye...
