The Appropriate Supplemented Feed for Nursing Larvae of Spot Spiny Eel (Macrognathus siamensis)

Abstract

            The study was conducted to determine the types of feed supplements which were appropriate for nursing larvae. Brood stocks of spotted spiny eel were collected from natural freshwater rivers and reservoirs in Surin and Buriram provinces, Thailand during January 2017- September 2018. There were 3 groups of 30-day larvae, feeding with different supplements supplied: group 1 only moina was given (designated as control or T1), group 2 both moina and vitamin C were given (T2), and group 3 both moina and fatty acid were given (T3). Experimental results showed that the highest average weight was found in the spiny eel larvae given both moina and fatty acid (T3) i.e. 2.57x10^-4±3.06x10^-6 g/larvae. Meanwhile the average weight of larvae of both T1 and T2 were 2.40x10^-4±7.00x10^-6and 2.48x10^-4±2.52x10^-6 g/larvae, respectively.
