Induction of spontaneous captive spawning, embryonic development and larval rearing in Mystus cavasius
Induction of spontaneous captive spawning, embryonic development and larval rearing in Mystus cavasius
We report induction of spontaneous spawning in Mystus cavasius in glass aquaria provided with water hyacinth for egg attachment. The brooders (20 to 25g) were injected intramuscularly with Ovatide™ at the rate of 0.2 millilitre/Kilogram body weight and introduced into the spawning tanks in the evening. Maximum spawning response was obtained when two pairs of brooders were housed in one tank.
