Abstract

In this review paper the present status of coastal lagoon and future challenges which will be faced by the coastal lagoon is discussed. Coastal lagoon provides great livelihood for a larger portion of human population through fisheries and tourism point of view thus crucial in socio economic aspect. Due to natural and anthropogenic activity, stress on coastal lagoon is increasing day by day. Thus steps should be taken for regular monitoring and planning for better management is found to be imperative in regards to present day situation.

Geographically the coastal lagoon is starched from arctic to the tropics (Nichols and Boon, 1994), covering 13% of the coastal region of the world may be ranged from<0.01 km² to>10 000 km² (Bird, 1994; Kjerfve, 1994). Regarding definition Emery and Stevenson (1957) had given the first scientific definition ever on coastal lagoon which states that “coastal lagoons are the bodies of water, separated in most cases from the ocean by offshore bars or islands of marine origin and are usually parallel to coast line”.
