| THE SEXUAL PROPORTION OF PENAEUS PENICILLATUS UNDER THE TREATMENT OF 17β-ESTRADIOL |
|
|
| Abstract: |
| In our first experiments, Penaeus penicillatus ahd been fed respectively with 10, 2040mg 17β-estradiol/kg diet for 70 days by oral treatment from the beginning of post larva stage, the proportions fo females to males in all the experimental groups were 1:1. In our second experiments, the zoea, mysis larvas and post larvas of prawn were respectively immersed in seawater solution of 17β-extradiol at concentration 5μg/L and fed simultaneously with estradiol at a dosage of 20 mg/kg diet. The immersion treatments didn't stop until the 30th day of the post larval stage and the oral treatments were continued till the sex differentiation could be seen by naked eyes, the proportions of females to males in all the second experimental groups were still 1:1. So we are of the opinion that the sexual rate of females to males and the expression of the sexual genes in Penaeus penicillatus are not influenced by 17β-extradiol. |
