A small population of dugongs was discovered in coastal waters of the Lease islands in eastern Indonesia. Studies on behaviour and feeding ecology revealed information on the interaction with seagrass meadows, modes of surfacing and submergence times and behaviour in the presence of scuba divers. Regular concentrated feeding was observed in a grazing sward at a subtidal monospecific Halophila ovalis meadow, confirming earlier observations of regular recropping by dugongs of grazing swards, covered by monospecific Halodule uninervis, inside an intertidal multi-species meadow.

For the management of molluscan stocks, knowledge of various population parameters and exploitation level of the population are needed. The present study assessed the population dynamics on the rock oyster Saccostrea cucullata (Born, 1778) in Karnataka State, south India. The specimens of S. cucullata were collected from Baindur rocky beach at monthly intervals from June 2010 to May 2011. Asymptotic length (L∞) estimated was 57.8 mm and growth coefficient (K) was estimated at 1.4 year-1. The sizes attained were 45.30, 54.72 and 57.04 mm at the end of first, second and third years of age, respectively. Total mortality (Z) was 5.24 year-1. Natural mortality (M) and fishing mortality (F) were 1.40 and 3.84 year-1 respectively. The life span of S. cucullata was estimated as 2.5 years approximately. Exploitation level (E) was computed as 0.73, indicating that the fishery of S. cucullata in the coastal waters of Karnataka Is overexploited.
