Abstract: Spawning in captivity of two red porgy's broodstock groups (Pagrus pagrus) of the same age was studied during one season.These two broodstock groups, designed A and B, were fed with different regimes during the spawning period.A group was fed on moist pellet while (A diet content 45% proteins, 10% lipids) B group was fed on fresh fish (A diet content 48 % protein, 8.7% lipids).The total eggs collected number for A group was 22 million eggs of which 18 million were viable, fertility was 474,966 eggs kg -1 female.For B group, eggs collected number was 36 million eggs of which 31 million were viable fertility was 769,186 eggs kg -1 female.Statistically, there was a significant difference between the two groups in terms of quantity and quality of spawning and larval survivals recorded on second day after hatching and on fifth day after hatching.
