By J Santhanakumar, A K A Nazar, N V Vinithkumar and R Kirubagaran

Abstract

During September - December 2004, mud crab fattening was attempted in tide-fed earthen ponds in\ud Lakshmipur (North Andaman) and Bamboo Tickri (Middle Andaman) with mangroves such as Rhizophora\ud mucronata, R. apiculata and Avicennia marina, covering 60 to 80% of the total pond area. Water crabs\ud of Scylla tranquebarica, S. olivacea and S. serrata, each weighing 500 - 1500 g were stocked in the\ud pond at a density of 0.5 kg/m2 with suitable hideouts to reduce cannibalism. In 30 to 35 days, 85%\ud survival was obtained with 8% weight increment. This paper outlines the measures that may be adopted\ud for practicing aquaculture in mangroves
