Some fish-eating birds and mammals have full bellies but poor diets, say biologists puzzling over declines among these high-latitude marine predators.

Managing Marine and Coastal Protected Areas: A Toolkit for South Asia (South Asia Toolkit) has been prepared to help MCPA managers in their daily tasks. Containing 81 theme sheets arranged in two parts: The Management Process and Conservation and Sustainable Use, the Toolkit provides up-to-date information and practical guidance on a wide range of issues related to management of MCPAs.

TUTICORIN: A workshop was organised on capacity building in identification of scheduled marine animals for officials of various departments including Forest Department, Customs and Coast Guard here on Tuesday.

marine sciences Rare corals aplenty According to researchers from James Cook University rare coral species might not be at high risks of extinction due to small population sizes.Their tendency to hybridize saves them. The previous prediction was that small population sizes led to decreased genetic diversity, which in turn decreased their adaptive capability. However, some

The coastal waters off western India may be the largest natural low-oxygen system. In summer and autumn the oxygen level drops to 0.2 mg per litre, said S W A Naqvi, chemical oceanographer at National Institute of Oceanography in Goa. During these seasons, the institute

RAMANATHAPURAM: Scientists have recorded the presence of several fish species, including the commercially important varieties, in the algal bloom-affected parts of the Gulf of Mannar, setting at rest fears that the problem might have caused the mass mortality of fish and highly endangered species. Fish species have also been spotted around the coral reefs in the affected areas.

This report summarizes the results of a global study on the development and present status of shrimp fisheries, with a focus on direct and indirect social, economic and environmental impacts. The study reviews the current situation, problems and issues, as well as the solutions found and the trade-offs made.

Regrowing affected population made easy Researchers of the National Institute of Oceanography (nio) in Goa have artificially repopulated corals in the Lakshadweep islands. Three years ago, the scientists started experimenting to develop a cost effective method to re-grow corals. About 60 per cent of them had died in 1998 in the islands. After trying different substrates
