The effect on growth and survival of the initial stocking density (30, 20 and 10 eggs L^-1) in larval rearing of spotted rose snapper (Lutjanus guttatus) was evaluated. The eggs were incubated in nine black fibreglass tanks with three replicates for treatment. Larvae were cultured in the same tanks using the green water technique. Larvae were harvested at 45 days post-hatch (DDE). Total length (LT), weight (PH) and survival rate (S) were determined. Initial stocking density did not affect growth and survival rates. Therefore, it is advisable to carry out larval culture of the spotted rose snapper using 30 eggs L^-1 to maintain good growth levels.

Key words: Fish larvae, culture density, fish growth, larvae survival
