Mariculture of the agar-yielding, red seaweed, Grucilariu edulis (Rhodophyta) was conducted in Minicoy lagoon during 1990-1992. Experiments were conducted on dry matter accumulation, effects of planting density, depth of water above culture nets, periodic cleaning for removal of epiphytes, grazing and the yield as well as regeneration of G. edulis after successive harvests to understand the optimum requirements of this seaweed. Six culture methods were tested and the yields obtained were compared to arrive at a culture method suitable for Minicoy lagoon.
Beach litter are man-made objects discarded directly or indirectly. This study brings out synoptic picture of status and composition of beach were found in Kerala (17), Maharashtra (12), Tamil Nadu (2), Andhra Pradesh (4), Odisha (7) and West Bengal (3). Whereas extremely littered beaches (>100 g/m 2 ) were found in Karnataka (13), Goa, Gujarat, and Andaman Island. With reference to the coastal population and per capita share of beach debris, Goa registered highest values (40.97 kg/head) and the Odisha coast registered the lowest values (0.005 kg/head).
