鲤鱼的繁殖。（家庭：本文对澳大利亚维多利亚沃茨的鲤科鱼类（Cyprinidae）的性腺成熟、产卵季节、产卵量和卵母细胞直径进行了详细的分析。结果表明，鲤鱼具有较高的年产卵量（12 ~ 154万卵母细胞/尾），其产卵量与尾叉长（L，mm）和体重（W，kg）呈正相关，而与年龄无关。体长或体重与AF的关系具有统计学意义，最好用简单的线性或二次回归来描述。平均相对繁殖力为16.3万粒卵kg−1全重。从八个种群的鲤鱼卵母细胞直径估计卵的大小。卵子大小与母体大小成正比，但与年龄无关。性腺指数的季节性趋势，连同卵巢的宏观和微观条件的变化，表明产卵一般在春季初夏高峰期，但也发生，直到秋季，甚至可以在冬末开始在一些网站。在维多利亚，这个物种是一个多产卵与异步卵母细胞发育和延长产卵季节。种群通常包含一次产卵的雌性和重复产卵的雌性，在产卵季节内。野生鲤鱼种群的控制管理的影响进行了讨论。
The reproduction of carp Cyprinus carpio L. (Family: Cyprinidae), from Victorian waters in Australia, is studied with detailed analysis of gonad maturation, spawning season, fecundity and oocyte diameter. Results show that carp has a high annual fecundity (AF) (0.12–1.54 million oocytes per fish), which is positively correlated with caudal fork-length (L, mm) and total weight (W, kg) but not age. The relationships between length or weight and AF were statistically significant and best described with the simple linear or quadratic regressions. Mean relative fecundity was 0.163 million eggs kg−1 whole weight. Egg size was estimated from oocyte diameter in carp from eight stocks. Egg size was proportional to maternal size but not age. Seasonal trends in gonadosomatic indices, together with the changes in the macroscopic and microscopic condition of ovaries, demonstrated that spawning generally peaks during spring–early summer, but also occurs through until autumn and can even start in late winter at some sites. In Victoria, this species is a multiple spawner with asynchronous oocyte development and a protracted spawning season. Stocks generally contain both females that spawn once, and females that spawn repeatedly, within a spawning season. Implications for management for the control of feral carp stocks are discussed.
