Growth of Metapenaeus monoceros supplemented with live-feed

C. Kaliaperumal, C. S. V. Ramachadnra Rao and P. Subramanian

Water quality management is the priority problem in the prawn culture industry to achieve better return. Usually water quality of a culture system deteriorate mainly by dissociation of compounded feed and discharge of excretory and metabolic products. In order to overcome the sestonic load due to compounded feed, present work on live feed supplementation was experimented over a period of 50 days. For this the abundantly available and untaxed potential live-feeds such as Cerithidium fluviatillis, Culex sitiens larvae, Orchestia sp., Ceratonereis casta and mixed feed (above live feeds on rotation) were tried at 4% food provision. Among all, polychaete feed showed higher growth followed by mosquito larvae, mixed feed, intertidal snail and amphipod feed. The moulting frequency were also observed to behave in the same order and the Food Conversion Ratio (FCR) behaves inversely.
