INDUCED BREEDING OF LABEO ROHITA AT NATIONAL FISH SEED FARM

The present paper deals with the induced breeding of Labeo rohita using ovaprim and ovatide (a spawning hormone containing salmon gonadotropin RH and domperidone) under moderate temperature (22-23°C) condition at National Fish Seed Farm. Bhadra Project, Karnataka. Optimum dose. fertilization percentage and hatching percentage have been calculated. The advantage of ovatide in induced breeding of Indian major carp. L. rohita is discussed. Success of the experiment at malnad region has brightened prospects of commercial exploitation of the species in Karnataka
