Hatchery protocol for silver therapon (Leiopotherapon plumbeus, Kner 1864)

Abstract

The hatchery protocol for silver therapon (Leiopotherapon plumbeus, Kner 1864) in outdoor tanks is disclosed. The process includes timed provision of preferred natural food commensurate with the age of larvae, pre-conditioning of rearing water, utilizing ambient lake water and the addition of fresh tropical almond leaves Terminalia catappa to enhance natural food supply in tanks. A stocking density of 0.1 to 1 larvae /L was used to enhance survival and growth. Survival of larvae increased to 35.41 ± 15.32 per cent using the invention.
