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 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. | Induction of spontaneous captive spawning, embryonic development and larval rearing in Mystus cavasius
