摘要
根据外观和组织学特征,将中华倒刺鱼巴〔Barbodes(spinibarbus)sinen-sis〕性腺分为6个发育时期,其发育有阶段性和连续性。由卵巢和成熟系数的变化,证实该鱼属分批产卵类型,产卵期为4~7月。雄鱼精巢为壶腹型,呈长带状。该鱼6冬龄以下个体相对和绝对怀卵量与体重呈显著正相关。
According to its morphological and histological characters, the gonadal development of Barbodes (spinibarbus) sinensis (Bleeker) is devided into six successive stages. Changes of ovary and maturation coefficients indicate that this species releases more than one batches of eggs during its reproductive period. The mature fish spawn from April to July. Tests are slim and long. The relationship between fecundity and body weight was discussed in this paper.
