Usually in the VAC system the fish pond ecosystem utilizes either raw animal manure or compost to improve the natural primary and secondary productivity for carp and tilapia aquaculture. Animal manure is also used in gardens mainly for vegetable cultivation. Such a system produces fish and vegetables for family consumption and surplus income. However the productivity of the pond is quite low ranging from few hundred kilograms to an average 1 5001 700 kg per ha per year 0 015-0 017 kg . Vegetables produced are mainly for subsistence. The coastal communities are always faced with the limitation of land for such an extensive system on one hand and low economic efficiency on the other. To address this issue the proposed project aims to improve the traditional VAC system through the application of new technology and cultivation of higher value species. This aim is expected to be achieved by meeting following three objectives i by providing an alternative income and ensure food security for the poor farmers and or fishers ii by improving technological and extension .
