Molecular Charcterisation of virulent genes of aeromonas hydrophila isolated from freshwater fishes of eastern india

Abstract

One of the formidable challenge before the world is to match the increase in global newlinefood production with the increase in world population which is predicted to become 11 newlinebillion by the year 2050. Even India s population is predicted to grow to approximately newline1.5 billion by 2030 and over take China. The challenge for agricultural sector is to double newlinethe food production by the year 2025 and triple it by the year 2050, on less land per capita, newlinewith less water and under increasing challenging environmental condition. At the present newlinescenario aquaculture has emerged as one of the most promising industry in the world. It is newlinea growing, vibrant and important production sector for high protein food. Aquaculture has newlinebecome one of the major economic activities in several nations (Balcazar et al, 2006). newlineAlthough it has a dimension of an industry, but it is a form of agriculture that involves newlinepropagation, cultivation of aquatic animals, plants and their marketing. Farming implies newlinesome sort of intervention into the rearing process to enhance production such as regular newlinestocking, feeding, protection from predators etc. (FAO, 2006). Being a significant socioeconomic newlineactivity, especially for rural communities, aquaculture contributes to livelihood newlineenhancement, food security and poverty alleviation through several mechanisms like newlineincome and employment generation, improvement of services, use of local resources, newlinediversified farming practices, domestic and international trade and other economic newlineinvestment (FAO, 2010). newlineAquaculture is considered to be one of the fastest growing animal food producing newlinesectors (Naylor et al, 2000). Current contribution of aquaculture to the world aquatic newlineproduction is about 51.7 million tons (FAO, 2006). The Asia-Pacific regions continues to newlinedominate the aquaculture sector, accounting for 89,1 percent of global production, with newlineChina alone contributing 62.3 percent of global production. Our country India is among newlinethe 15 leading aquaculture producing countries. It is blessed with a diverse range of native newlinef
