摘要
本文对黄海南部黄鲫群体进行了常规生物学测定。研究分析了体长组成和体重组成、体长和体重关系、性比的变化及性腺的发育情况。总样品的性比为♀ /♂ =0 .96 ,体长与体重的关系式为 W=1.77× 10 -2 L2 .73。优势体长为 12 - 15 cm,占74.8% ;优势体重为 2 0 - 40 g,占 6 7.8% ;年龄组成为 1- 4龄 ,以 1龄和 2龄鱼占优势。
The general biological characters of Setipinna taty in the Southern Yellow Sea were studied in this paper.The composition of Setipinna taty according to body length and weight were analysed.At the same time the relationship between length and weight were analysed.Also,the varity of sexual ratio and the development of the sex gland were studied.The sexual ratio of total samples was female: male=0.96,the relationship between length and weight was:W=1.77×10 -2 L 2.73 .The dominant length was 12-15cm, accounting for 74.8%;the dominant weight was 20-40g, accounting for 67.8%. The age composition was 1 to 4 years, the dominant being 1 and 2 years.
