Description Coastal development includes a variety of activities which will have significant impact on marine ecosystem especially in the shallow nearshore areas. The stress relevant to coastal zone emerge from hinterland activities, urban development and waste disposal, sea transport and exploitation of living and non-living resources. Mitigation actions to reduce stress on marine ecosystem especially the living resources of the coastal watrs are required to ensure long term sustainability of biomass yields and conservation of natural resources. The problem has become crucial and the only alternative is the implementation of Environment Impact Assessment (EIA) to evolve environmental management strategies for optimum use of a given coastal area without disturbing the natural equilibrium of the ecosystem. Overfishing is a direct threat to the marine resource as well as to the sustainable yield by altering the food web by removal of selected populations that constitutes a significant part of the ecosystem. Though a set of negative aspects of fishing have been developed, an operational definition of marine environmental quality for fishing activity is yet to be formulated within a rational framework. There is growing concern about the environmental implications of aquaculture development. The environmental impact of marine fish farming depends very much on species, culture method, stocking density, feed type, hydrography of the development, provided pollution loading generated by fish farms are kept well below the carrying capacity of the coastal system. Effects can be reduced by careful site selection and adopting standard methodologies including integrated culture. It is recommended that any attempt to combat marine pollution should be governed by strict enforcement and tougher sanctions for non-compliance.
