iv. A major foreign exchange earner

Unfortunately, since the advent of more intensive modern industrial aquaculture, serious environmental and social issues have developed. Millions of indigenous coastal people are being adversely affected

i. Among the most serious problems is the degradation and loss of natural coastal resources.

ii. Local waters and species may also become contaminated with antibiotics, herbicides and other medicines that are be used in aquaculture ponds.

iii. Accumulation of organic matter, both in the form of unconsumed feed and faeces. When aquacultural activities are conducted directly in the marine or brackish environment lead to a process of eutrophication, with associated depletion of oxygen in the water bodies.

iv. The loss of mangrove swamps and wetlands by conversion their area into shrimp farms will lead to exposure of coastal areas to erosion, flooding, increased storm damage, altered natural drainage patterns, increased salt intrusion and removed critical habitats for aquatic and terrestrial species.
