| dc.description.abstract | Two experiments were conducted with the objective of assessing the effect of two selected diets on the growth performance, survival rate and food preference of snakehead fish larvae (Channa sp.). The experiments were carried out using 60-liters capacity glass aquaria with 20 liters of water volume. Live food such as Artemia sp. nauplii and Moina sp. were given to larvae three times daily from 1-21 days after hatching when the yolk sac was totally absorbed by the larvae. The first experiment was conducted to evaluate the growth performance and survival rate of snakehead larvae fed with Artemia sp. nauplii and Moina sp. Results showed higher length gain, weight gain, and SGR in larvae fed with Artemia sp. nauplii compared to larvae fed with Moina sp. with value 23.3187 mm, 118.35 mg, 11.4994% and 21.7714 mm. 84.4267 mg, 10.0124%, respectively. In the present study, higher mortality due to cannibalism was also observed in larvae fed with Artemia sp. nauplii (19.6667 ± 6.50) compared to Moina sp. (14.3333 ± 10.04). Meanwhile, survival rate was observed to the higher in larvae fed with Moina sp. compared to larvae fed with Artemio sp. nauplii with values, 56.3333 ± 10.59 and 45 ± 15.04, respectively. Statistically, no significant difference was observed in both treatments in terms of length gain, weight gain, SRG, cannibalism and survival rate. The second experiment aimed to determine the food preference of snakehead fish (Channa sp.) larvae. It was found out that the snakehead fish age 13, 20 and 27 days old consumed both Artemia sp. nauplii and Moina sp. However, statistical analysis showed significantly higher relative percentage occurrence of Moina sp. compared to Artemio sp. nauplii in the digestive tract of snakehead fish of age 13, 20 and 27 days old with values 65.6218, 67.0354, 54,6904 % and 34.3782, 32.9646 and 45.3096 %, respectively. The study suggested that Moina sp. is a suitable live food and a potential substitute for Artemio sp. nauplii in the larval rearing of snakehead fish (Channa sp.). | |
