日本山口县外海水产试验场利用牙鲆的遗传因子,研究繁殖大个体的雌性牙鲆和中性牙鲆。以往,尽管雌鱼在孵化后2年左右可养成1公斤左右的成鱼,而雄鱼只能长到500克左右。现在繁殖出的中性牙鲆如同雌鱼一样,鱼体可迅速长大。通过使雌性和中性牙鲆的胚胎发育,可提高养殖效率。 Japan’s Yamaguchi Prefecture Offshore Fisheries Experimental Field Paralichthys olivaceus genetic factors, the study of large-scale reproduction of female Japanese flounder and neutral flounder. In the past, although the females can raise about 1 kg of adult fish about 2 years after hatching, the male can only grow to about 500 grams. Now reproduce the neutral flounder as the same as the female, the fish can grow rapidly. Breeding can be enhanced by developing the embryos of both female and neutral flounder.
