| 摘 要： | 本文探讨了深圳湾大弹涂鱼种群结构和生殖特征。结果表明：该种群以１、２龄鱼组成为主，３龄鱼极少，表明种群结构简单，体长与体重的相关曲线方程为Ｗ＝４．１６１８×１０－５Ｌ２．７４５１（ｒ＝０．９５７６）。雌雄性比为３：２。一龄鱼开始性成熟。雌鱼性成熟最小生物学体长为６２ｍｍ，雄鱼为５９ｍｍ。个体绝对生殖力波动于１９５６—１４０５３粒，平均７２９３粒；个体相对生殖力Ｆ／Ｌ：２９．５—１００．５粒／ｍｍ，平均７９粒／ｍｍ；Ｆ／Ｗ：５１１．０—８０４．９粒／ｇ，平均７５２粒／ｇ。４—６月为繁殖盛期，７—８月为繁殖末期。雌性周年月平均成熟系数（ＧＳＩ）变动范围为０．２７％—４．３６％。大弹涂鱼在一个生殖季节中只能产卵一次，属于一次性排卵类型。

| Abstract: | This paper sudies the population structure and reproductive chracteristics of mud skipper, Boleophthalmus pectinirostris, in Shenzhen Bay, Guangdong province. The results show that the population includes the classes age of 0, 1, 2, and 3 years, and they account for 12. 58%, 58. 70%, 27. 40% and 1. 26% of the total number, respectively. The relationship between body length and weight is computed by the equation: W=4. 1618 × 10-5L2.7451. The sex ratio of females to males is 3: 2. The fish begins maturating a... |
