| 内容記述 | It is advisable to breed females alone in culture because the growth rate is greater in females than in males. The experiment was carried out from this viewpoint, and the results obtained are as follows: Inducement of sex reversal is considered impossible in each group of loach reared with the feed containing 5, 10, and 60 ug/fish/day of estrone for 45 days from the 38th day after hatching. Sex reversal was successful in the group of loach immersed in estrone solution of 250 ug/l for 56 days from the 12th day after hatching. There were bony plates (lamina circularis) on pectoral fins in 17% of female and 75% of intersex, and processes on the dorsal parts of body sides in 12% of female, and 75% of intersex of the group of loach immersed in estrone solution of 250 ug/l. Mean value of the proportion of ovary weight to body weight was smaller in the group of loach immersed in estrone solution of 250 ug/l than in the control group. The body weight at the end of experiment in the groups treated with estrone solution of 250 and 500 ug/l was greatest in female, smallest in male and middle in intersex. There was no difference in the body weight of female at the end of experiment between the group of loach treated with estrone solution of 250 ug/l and the control group. Weight-multiplicating rate in the group of loach treated with estrone solution of 250 ug/l was 1.6 times as large as that in the control group. Decreasing rate and weight-multiplicating rate in the group of loach reared with the feed containing estrone were larger and smaller respectively than those in the group of fish without hormone. Prior to this experiment, these groups of loach were immersed in estrone concentration of 250, 500, 1000, and 1500 ug/l respectively for 35 days from the 12th day after hatching. The most suitable concentration of estrone solution is 250 ug/l for sex reversal of the loach with estrone in culture. | |||||||||||
