试验表明台湾海峡牙鲆亲鱼不同雌雄比例与产卵量和受精卵有直接的关系。亲鱼雌雄比例为1∶0.625时,每尾雌鱼的产卵量仅为13.7万粒,平均受精率为82.3%;当亲鱼雌雄比例为1∶1.702时,每尾雌鱼的产卵量可达43.79万粒;平均受精率为88.6%。
Tests show that the ratio of males and females in the Taiwan Strait Paralichthys olivaceus and oviposition and fertilized eggs are directly related. When the ratio of male and female broodstock was 1:0625, the fecundity of females was 137,000 and the average fertilization rate was 82.3%. When the brood stock ratio was 1: 1.702, the fecundity of females was up to 437,900; the average fertilization rate was 88.6%.
