The World Meteorological Organization’s State of the Climate in Asia 2024 report warns that the region is warming nearly twice as fast as the global average, driving more extreme weather and posing serious threats to lives, ecosystems, and economies. In 2024, Asia experienced its warmest or second warmest year on …
Coral reefs have exceptional biodiversity, support the livelihoods of millions of people, and are threatened by multiple human activities on land (e.g. farming) and in the sea (e.g. overfishing). Most conservation efforts occur at local scales and, when effective, can increase the resilience of coral reefs to global threats such …
Vocational training to be given for fishermen Conservation measures:A team of United Nations Development Programme, New Delhi, at Kurusadai Island in Gulf of Mannar near Mandapam on Thursday. KURUSADAI ISLAND (GULF OF MANNAR): R. Srinivasan, Assistant Country Director, United Nations Development Programme, (Energy and Environment), New Delhi, said it would …
Humans have reduced the abundance of many large marine vertebrates, including whales, large fish, and sharks, to only a small percentage of their pre-exploitation levels. Industrial fishing and whaling also tended to preferentially harvest the largest species and largest individuals within a population. We consider the consequences of removing these …
Bycatch throws a serious threat to the marine diversity and the sustainability of marine fisheries, said CMFRI, Kochi Principal Scientist Dr E V Radhakrishnan. Delivering a key-note address at a workshop on
After months of gloom, a report on the fate of the oil from BP's Deepwater Horizon spill offered a rare piece of good news. "At least 50% of the oil that was released is now completely gone from the system," said Jane Lubchenco, administrator of the National Oceanic and Atmospheric …

Vinaya Deshpande & Meena MenonMumbai: The oil leak from MSC Chitra could not have happened at a worse time. This is the breeding season for marine animals, and environmentalists fear that the spill may impact not only the breeding cycle, but also much more in the future if the oil …
Vernon Asper was one of the first researchers in the Gulf of Mexico to study the oil gushing out from the BP well. But it has not all been smooth sailing, reports Mark Schrope.
This is the story of how our fishermen, having taken so many fish from the seas closer to home, are now venturing to the ends of the Earth in order to maintain our insatiable appetite for seafood. This is also the story of how a group of Antarctic scientists, environmentalists, …
India has a vast extent of coast line of about 8000 km spanning 13 maritime mainland statesand Union Territories, which are home to a diversity of coastal and marine ecosystems,comprising nationally and globally significant biodiversity (Venkataraman and Wafar, 2005).It also supports almost 30% of its human population being dependent on …
Phytoplankton biomass is a crucial measure of the health of ocean ecosystems. An impressive synthesis of the relevant data, stretching back to more than 100 years ago, provides a connection with climate change.
In the oceans, ubiquitous microscopic phototrophs (phytoplankton) account for approximately half the production of organic matter on Earth. Analyses of satellite-derived phytoplankton concentration (available since 1979) have suggested decadal-scale fluctuations linked to climate forcing, but the length of this record is insufficient to resolve longer-term trends. Here we combine available …
RAMANATHAPURAM: The Forest Department would go ahead with the proposal to lay buoys in Gulf of Mannar so as to demarcate the protected area, said Collector T.N. Hariharan. He made the announcement on Wednesday after undertaking a visit to the Kurusadai island in the Gulf of Mannar accompanied by Sundarakumar, …
There is increasing concern that ocean acidification, caused by the uptake of additional CO2 at the ocean surface, could affect the functioning of marine ecosystems; however, the mechanisms by which population declines will occur have not been identified, especially for noncalcifying species such as fishes. Here, we use a combination …
Since the collapse of the pelagic fisheries off southwest Africa in the late 1960s, jellyfish biomass has increased and the structure of the Benguelan fish community has shifted, making the bearded goby (Sufflogobius bibarbatus) the new predominant prey species. Despite increased predation pressure and a harsh environment, the gobies are …
Successful ocean management needs to consider not only fishing impacts but drivers of harvest. Consolidating post-1950 global catch and economic data, we assess which attributes of fisheries are good indicators for fishery development. Surprisingly, year of development and economic value are not correlated with fishery trophic levels. Instead, patterns emerge …
