An Economically Viable Approach for Induced Breeding of Labeo Rohita by Ovatide, Ovaprim And Carp Pituitary Extract.

Abstract

Indian major carp Labeo rohita was induced breeding in eco-carp hatchery with 3 different inducing agents, viz. ovaprim, ovatide, Carp pituitary extract at fish breeding center at Amloh Distt. Fathegarh Sahib (Punjab) India. Total ten trial doses of ovaprim, ovatide and Carp Pituitary Extract (CPE) used for induced breeding in Labeo rohita. The fertilization was found 61.30% with ovaprim, 58.50% with ovatide and 55.96% with carp pituitary extract treatment. The percentage hatchling was 72.20% with ovaprim, 66.37 % with ovatide and 59.25% with carp pituitary extract treatment.A comparison was carried out for fecundity, fertilization, and hatching rate during the induced spawning of Labeo rohita administered single dose of ovaprim and ovatide while carp pituitary extract double dose to female brooder. Ovaprim performed much better than Ovatide and pituitary gland extract.
