Natural Microbial Resources and their Role in Sustainable Development of Aquaculture

Global fish production continues to outpace world population growth and aquaculture remains one of the most promising as well as fastest growing industries and provides high quality protein diets. Over the last three decades, much effort in research has increased in fish growth efficiency by manipulation of dietary formulation. Along with the increasing demand, the main challenge is disease outbreak and thus massive economic losses. Due to harmful effects of vaccines, antibiotics and various chemotherapeutics, an alternate approach can be used for naturally occurring microbial resources in aquaculture system to enhance growth, immune system and also to control diseases. The present work concentrate on the gut microbes of vermicomposting earthworm and role of cellulolytic microbes in fish feed formulation with the help of fermentation process.
