| 摘 要： | 对大银鱼个体生殖力及其雌亲体的形态学指标进行了研究。结果表明：大银鱼的绝对生殖力Ｆ随体长、体重增加而增大，体长每增加１ｍｍ，卵粒增加６３６粒；体重每增加１ｇ，卵粒增加１０６８粒。大银鱼存在两群发育程度不同的大型卵母细胞，首批产卵数占生殖力总数的４８．３％，第２批为５１．７％。

| Abstract: | A study was conducted on the fecundity of the female Protostanx hyalocranius as well as its morphology index. The result showed the enhancement of the absolute fecundity(F) of Protoslenx hyalocranius was with the depending of its body length and weight increased: as the body length increased 1 mm the spawns increased 636 particles and as the body weight increased 1 g the spawns increased 1068 particles. There are two gromp of the big-sized ovocytes of Protoslanx hyalocranius in different development level. The first spawning number accounts for 48. 3 % of the total number of the fecundity and the second accounts for 51. 7 %. |
