Seduced Breeding of Indian Major Carps (Labeo rohita, Cirrhina mrigala and Labeo calbasu)

Abstract:

Seduced breeding was tested in Labeo rohita, Cirrhina mrigala and Labeo calbasu in two different breeding pool selections, where the males were always injected with pituitary gland hormone (PG) and the females were either not injected or a portion of the females injected with a single or two split doses of hormone (PG). There were fourteen attempts involving 135 different females in all the species. The average percentage of females ovulating was 96% in the noninjected group (seduced breeding) while the percentage of females ovulating in the mixed group (sympathetic breeding) averaged 63%. The average rates of fertilization in the two breeding pool selections were both around 83%. The results of the experiments suggest that the females during their optimum reproductive period can successfully undergo seduced or sympathetic breeding under hatchery conditions.
