C1 3 g kg−1, C2 5 g kg−1, t1 supplementation at spawning, t2 supplementation after the first harvest, t3 supplementation at spawning and after the first harvest. Values are means; means within the same column followed by the same letters are not significantly different at P < 0.05 according to Duncan’s multiple range test.
