Abstract
The results of the effect of five different incubation temperatures on the development of clownfish (Amphiprion ocellaris) larvae are presented. This ornamental species is widely marketed worldwide and is reared in captivity at CIAD to meet the demand in the domestic market. The experimental work was carried out over 30 days post-hatching to observe the temperature's effect on the development of the larvae's vertebral column and caudal complex. The eggs were incubated at 26, 28, 30, 32, and 34°C. The percentage of hatching, survival, growth, and the presence of skeletal malformations were evaluated. Hatching and survival percentages did not show significant differences between treatments. Regarding growth, there were significant differences between treatments, with organisms showing slower growth at 26°C and larger sizes at 34°C. The highest percentage of malformations occurred in larvae cultured at 34°C, with lordosis being the most frequently observed deformity among the treatments. Therefore, it can be concluded that the optimal temperature range for cultivating and harvesting quality A. ocellaris organisms is between 28 and 30°C.
