Abstract. Effects of low doses of salmon gonadotropin (SG-G100) and three steroids — 17α,20β-dihydroxyprogesterone (17α,20β-diOHprog), deoxycorticosterone (DOC) and progesterone — individually, or combinations of steroid with SG-G100, on ovulation and hatching in Clarias batrachus (L.) were investigated. None of the steroids at any of the three different dose levels (1μg, 1·5μg/g and 2μg/g BW) could induce ovulation when injected alone. SG-G100 at a dose level of 10 μg/g BW was not effective but at the dose level of 15 μg/g BW it could induce ovulation. All the three steroids at their lowest doses (1μg/g BW) when injected in combination with SG-G100 (10μg/g BW) were significantly effective in inducing ovulation. When hatching percentage was taken into account, 17α,20β-diOHprog in combination with SG-G100 was found to be the most effective combination in comparison with other treatments.
