Spawning biology, embryonic development and captive breeding of vulnerable loach Botia dario (Hamilton)

Dey A, Sarkar D, Barat S

Botia dario is an vulnerable species (CAMP, 1998) [4] having both ornamental as well as edible value. Breeding experiments in captivity were conducted successfully for the ornamental fish B. dario in May 2013-2015 using synthetic hormone. This fish spawned only in running water system. The fecundity of the females ranged from 13,880 to 27,510. The average fertilization rate was found to be 82.09 %. The average Gonado-Somatic Index of B. dario for female was 13.21 and for male 3.4. About 14.30-14.40 hours after fertilization the embryo hatched out from the chorion of the egg. The present work contributed to the deficient information on embryonic development, induced breeding and breeding behaviour of B. dario.
