南方白甲鱼年龄和生长的研究

Studies on the age and growth of Vocricorhinus gerlachi(peters)

摘要: 对华南地区的南方白甲鱼的年龄、体长、体重组成进行了研究,对其生长规律进行了分析.体长与体重的总公式是lgW=lg0.00479+3.399lgL.生长方程式Lt=43.3×(1-e-0.227(t+0.9996);Wt=1557.085(1-e-0.227(t+0.9996))3.

Abstract: The age,body length,weigth and growth character of vacricorhinus gerlach in south China were investigated.The relation between length and weigth can be expressed as follows,lgW=lg0.00479+3.399lgL.The growth oquations for length and weight are Lt=43.3×(1-e-0.227(t+0.9996))and Wt=1557.085(1-e-0.227(t+0.9996))3,respectively.
