This case study review shrimp aquaculture development in Ecuador. The prevailing farming systems and practices are described. Most farms are extensive or semi-intensive and the industry is shifting to hatchery-reared PL rather than wild due to unpredictability in wild PL supply and disease outbreaks. A survey of water quality intake and outfall from farms is reported on with suggestions for farm design to reduce nutrient load in outfall is discussed. Health issues and mangrove degredation are discussed. 

The goal of this project was to optimise the economic yield from mixed shrimp aquaculture-mangrove forestry farming systems in Ca Mau Province, Vietnam, in a sustainable manner. Specific objectives were to investigate factors controlling the yields of shrimp and wood from shrimp farming-mangrove systems, experiment with shrimp pond and mangrove forest management to evaluate different culture options, identify improved practices and assist government to transfer the results of the project to the wider coastal farming community.

Ths paper enumerates different carp integrated farming systems being prevalent in Asia along with successful case studies indicating potential and constraints of such systems. It recommends to integrate carp farming with agriculture and irrigation, livestock farming, sewage utilisation and water pollution control not only to increase the productivity of land and water and improve the economic conditions of poor farmers but also to maintain health and hygiene of the rural poor and city dwellers alike.
