Spawning biology and proper dose of hormone for captive breeding of vulnerable fish, Botia rostrata (Gunther), in Cooch Behar, West Bengal, India

Arpita Dey, Debapriya Sarkar, Sudip Barat
Botia rostrata is an vulnerable species (CAMP, 1998) having high ornamental value. Breeding experiments in captivity were conducted successfully for the ornamental fish, Botia rostrata using synthetic hormones. Induced breeding of B. rostrata with WOVA-FH at 0.025 ml per fish was achieved. Sex ratio 1:1 (male: female) were maintained in two trials. These fish spawned only in running water system. The fecundity of females ranged from 14,103 to 21, 352. The average fertilization rate was found to be 67.60%. The present work contributed to the information lacking on induced breeding and breeding behaviour of Botia rostrata.
