Feminization of GYMNOCORYMBUS TERNETZI (BOULENGER) using Short Term Immersion with Estradiol �17 ?

B. Uma

Abstract :

 Control population had a highly skewed sex–ratio in favour of males (59%), possibly due to temperature induced / based natural sex reversal.  Intersexes were also observed in the control stock. With Estradiol –17b, a single short term immersion of 600 mg/l for 7 hours yielded 61% females, while 600 mg/l for 10 hours resulted in 71% females.  Among the two, treatment for 7 hours resulted in better survival (36%) than for 10 hours (11%) and thus recommended for adoption. Intersexes were observed in the hormone exposed lots at both sub–optimal and super–optimal doses.  Sexes were identified through gonadal squash
