    Abstract

    The diversity and distribution of marine macro algal resources of Indian waters are affected since early 1970s due to over exploitation, sediment deposition and discharge of effluents, changes in the environmental factors, water temperature, light intensity, tidal waves, cyclones and consequence of bottom trawl fishing. As a result, there is decrease in algal production in Gulf of Mannar, Andhra coast and Kerala coast. On the other hand, there is rising demand for the phycocolloids viz. agar, algin, carrageenan and others. In this context there is an urgent need for conservation and better exploitation of the resources. Regulation of exploitation, control of pollution by domestic and industrial effluents, conducting algal culture are proposed as measures to overcome the damage to natural algal stocks to enable conservation and sustained production. Attempts have to be made to assess the availability and distribution of marine algae in deeper waters using remote sensing techniques, spot satellite imagery as is done in France (Brittany), English Channel and Australia. The details are discussed in the paper.
