| 内容記述 | It is advisable to breed female alone in the culture of the loach Misgurnus anguillicaudatus, because the growth rate is usually greater in the female than in the male. Influence of initial age and duration of estrone treatment of 300 ug/l on sex reversal in the loach was studied from this viewpoint. The results obtained are as follows: The sex reversal was obtained in the groups immersed in estrone solution for 40 days at the initial ages of 2, 5, 10 and 20 days after hatching, and for 30, and 50 days at the age of 5 days, but was not observed in the groups immersed for 40 days at the age of 30 days and for 10 and 20 days at the age of 5 days, respectively. Percentage of the malformed fish to the total fish treated showed the highest value, 45.5 %, in the group immersed in estrone solution for 40 days at the initial age of 2 days, and the lowest value, 4 %, in the group for 30 days at the age of 5 days. There was no difference in the body weight of female at the end of the experiment between the sex reversal and the control groups. Mean value of the proportion of ovary weight to body weight was smaller in the sex reversal groups than in the genetic female groups of the control fish. The authors concluded that it was a highly suitable method for the inducement of sex reversal of the loach to immerse them in estrone solution of 300 ug/l for 30 days at the initial age of 5 days or for 40 days at the age of 10 days after hatching. | |||||||||||
