| 内容記述 | The possibility of a large-scaled cold shock induction of triploidy, viability of triploid fish and growth performance were investigated in yellowtail Seriola quinqueradiata. Induction of triploidy by a large-scaled cold shock (approximately 0.1 million fertilized eggs) was successful in our preliminary test, and approximately 40 thousand hatched larvae were obtained. Some of the hatched larvae were tested for polyploidy, the results of which indicated that fish treated with two different cold shocks (two trials) were 100% triploid. Then, the growth performance of the triploid and diploid fish was investigated in both mixed and separate rearing. At the age of 100 and 122 days, the body weights of the triploid and untreated control fish were not significantly different in both mixed and separate rearing in two trials. However, as they grew larger, the growth rate of the untreated control was significantly higher than that of the triploid fish in both rearing conditions. Thus, the triploid fish at early development (at least half a year) showed a delay in growth. Also, the triploid fish showed longer term viability. In future studies, we will investigate growth performance at larger size and infertility (gonadal developmental stage) at the age of maturation. | |||||
