Abstract: Shrimp farming in many parts of the world causes pollution to the environment. Upstream shrimp farmers dump untreated waste water that typically contains unconsumed feed, chemicals and even diseases into river system, polluting surrounding areas as well as downstream areas. We study experimentally solutions to the wastewater pollution problem of shrimp farming with upstream and downstream externality. The results show that an external monitoring and certification agency does not help while communication helps greatly laboratory shrimp farmers in solving the pollution problems. Once the problem is solved, the farmers manage to sustain self-governance. This suggests the possibility of community-based solutions in the field
