    Abstract


    The study was conducted with five treatments (1, 2, 3, 4 and 5 ind./l) in order to identify the most suitable density for rearing orange clownfish larvae. Results showed that the fish reared at the densities of 1, 2 and 3 ind./l gave the highest specific growth rate (3,95; 3,87 and 3,77%/day, respectively), followed by the density of 4 ind./l (3,27%/day), the lowest at the density of 5 ind./l (2,99%/ngày); (p < 0,05). Similarly, the fish larvae reared at the densities of 1, 2 and 3 ind./l gave the highest total length (12,41; 12,09 and 11,76 mm), followed by the 4 ind./l (10,12 mm) and the lowest at 5 ind./l (9,32 mm); (p < 0,05). The fish larvae reared at the densities of 1, 2 and 3 ind./l obtained the highest survival rate (86,67; 83,33 and 78,89) followed by the 4 ind./l (55,83%) and the lowest at 5 ind./l (40,67%). In conclusion, the most appropriate density for rearing the orange fish larvae is 3 ind./l in order to optimize the growth, survival rate and economic efficiency.
