Abstract:
This study aimed to determine the effects of dietary supplementation of organic selenium (OS) on growth, survival, as well as the physiological and hematological status of snub-nose dart, Trachinotus blochii. Five diets supplemented with OS-Selplex (Selplex, Alltech, USA) at 0, 0.1, 0.2, 0.3 and 0.4 g/kg were fed to fish (2.30 ± 0.28g, average wt) for 8 weeks. Survival was significantly highest (P 〈 0.05) when the fish were fed the 0.3 g/kg OS-Selplex supplemented diet. Growth, flesh protein, and liver lipids, were significantly higher (P 〈 0.05) in fish fed all OS-Selplex supplemented diets compared to the control group. Flesh moisture content was lower (P 〈 0.05) in fish fed 0.2, 0.3 and 0.4 g/kg OS-Selplex supplemented diets. Hematocrit values (Ht) of the fish fed 0.3 and 0.4 g/kg OS-Selplex supplemented diets were higher than in fish fed the other diets (P 〈 0.05). The highest proportions of monocytes were obtained in fish fed 0.2 and 0.3 g/kg OS-Selplex supplemented diets. The results suggest that feeding 0.3 g/kg of OS-Selplex in diets increases growth performance and health status of snub-nose dart.
