Aquaculture effluents represent a main environmental concern because of their high polluting potential. While fish farms of advanced countries adopt a medium/high-tech approach to this issue, less industrialised countries rely on low-tech systems, if any. Shrimp culture is an important economic sector in which Asian countries are the main producers/exporters and industrialised countries are the main importers/consumers. Asian aquaculture makes up almost 80% of world shrimp (P. monodon and P. vannamei) production. As most of the shrimp farms have serious negative impacts on environment caused by waste effluents containing pollutants, one of the main needs of Asian shrimp culture is the implementation of advanced effluent management systems which can burst the rearing efficiency up to manifold increase of production, reducing the environmental impact. On the other hand, EU aquaculture, which possesses a large know-how on intensive fish farming, lacks of intensive shrimp culture because the only species reared (P. japonicus) can be grown only in extensive plants. The present project envisages a complementary cross-exchange of their know-how and competencies in the field of shrimp culture between EU and Indian researchers. Respective aims are: (i) the implementation of cost-effective systems for the treatment of shrimp farm effluent to reduce the environmental impact of Indian commercial aquaculture; (ii) the implementation of closed systems for the reproduction and growth of new shrimp species (P. monodon and P. vannamei) suitable for intensive rearing in EU aquaculture. Available systems and applicable technology will be considered for application and their efficiency to prevent recipient ecosystem pollution will be verified and monitored through analytic characterisation of water, waste and the recipient ecosystems. Specific dissemination and training actions for will be performed to extend the knowledge to researchers, operators and policy makers of India and EU.
