Summary : In Thai Binh Province (North Vietnam) the political authorities give great importance to freshwater fish farming. With the aim of producing tilapia for export, they are using subsidies to promote improvement in the management of 6,600 hectares of fish ponds and conversion of 7,000 hectares of low yield paddy-fields into fish ponds. Furthermore, through integrated agriculture-aquaculture, fish ponds make it possible to recycle animal manure, especially that of pig’s produced on the farms. Different kinds of farms have been characterized. Their evolution in the future has been forecast through a diagnosis concerning their recycling capacity of the part of animal faeces which will be produced by the pig farming intensification project planned for 2010. The building and ecological intensification of a fish farming model integrated with pig production could achieve a double objective planned by the local authorities: to increase the recycling capacity of pig manure by ponds and to produce tilapias for export.
Keywords : animal production, fishing and aquaculture
