Description The region of Gulf of Kutch was possibly more an arid zone in the pleistocene, almost approaching to a desert condition, than what it is at present. The Gulf of Kutch covers an area of circa 7,350 sq. km with a maximum depth of 60 m. The tidal range varies from 3.06 to 5.89 m with an average of 4 m. The intertidal zones are sandy and muddy or with sandstones of vast expanse and prolonged exposure.
The present report is based on a six weeks survey carried out in the Gulf of Kutch mainly around Okha and Jamnagar in 1978 with a view to obtaining additional information on the major marine and coastal habitats, particularly the coral formations and the mangroves. The prevailing physical features,animal communities and the visible ecological impact on the ecosystems due to human interference are
briefly discussed. The most important physical factor that at present aifect the marine life of Gulf of Kutch seems to be the high degree of sedimentation. Existence of extreme physical conditions such as prolonged exposure due to very high tidal amplitude is a major factor that applies constraints on the colonization of many marine animals. The higher rate of sedimentation in the inshore waters of Gulf of Kutch appears to be the most deleterious physical factor that affect the marine fauna at present.
