The original application was registered suo-motu based on the news item titled "Nayar …
Judgement of the National Green Tribunal (Southern Zone, Chennai) in the matter of M/s. Pannaiyoor Regional Citizens Welfare Trust Rep. by its Secretary, Kannyakumari District Vs.The Ministry of Environment and Forest Union of India Rep. by its Secretary, New Delhi dated 29/09/2015 regarding appeal for setting aside the Coastal Regulation …
Populations of fish critical to human food security are in serious decline worldwide with some at risk of collapse according to the emergency edition of a WWF report released. WWF’s Living Blue Planet Report finds that much of the activity threatening the ocean is avoidable and solutions do exist to …
Traditional fish workers and trawl operators in Kerala, long at loggerheads, have framed a code of responsible fishing practices. The article argues that this landmark agreement between two hitherto irreconcilable groups was borne out of a crisis in pelagic fish resources. It also argues that the agreement holds important lessons …
The deep sea is the world’s largest ecosystem, with high levels of biodiversity and many species that exhibit life-history characteristics that make them vulnerable to high levels of exploitation. Many fisheries in the deep sea have a track record of being unsustainable. In the northeast Atlantic, there has been a …
Odisha state cabinet approved ‘Fisheries Policy, 2015’, with an objective to increase the productivity and production of fish from island, marine and brackishwater resources. As per the Odisha Fisheries Policy: The state government has set targets 7.15 lakh tonne of total fish production by the end of 2019-20 from present …
Heavy metals are found naturally in micro quantities in all aquatic systems. In fact, some of them are essential micronutrients for living organisms. However, they became highly toxic to the organisms when present in higher concentrations. These metal concentrations have been altered in the ecosystem by indiscriminate anthropogenic activities and …
Climate change that is linked to the build up of greenhouse gases and aerosols in the atmosphere has led to increases in the earth's surface temperatures over the last 50 years. As a result the water in the world's rivers, estuaries and the sea are also heating up. Fish are …
Some animals have the remarkable capacity to acclimate across generations to projected future climate change however, the underlying molecular processes are unknown. We sequenced and assembled de novo transcriptomes of adult tropical reef fish exposed developmentally or transgenerationally to projected future ocean temperatures and correlated the resulting expression profiles with …
Coastal communities are particularly at risk from the impacts of a changing climate. Building the capacity of coastal communities to cope with and recover from a changing environment is a critical means to reducing their vulnerability. Yet, few studies have quantitatively examined adaptive capacity in such communities. Here, we build …
Ocean acidification negatively affects many marine species and is predicted to cause widespread changes to marine ecosystems. Similarly, freshwater ecosystems may potentially be affected by climate-change-related acidification; however, this has received far less attention. Freshwater fish represent 40% of all fishes, and salmon, which rear and spawn in freshwater, are …
Parallel studies of nesting colonies in Mexico and the United States show that Elegant Terns (Thalasseus elegans) have expanded from the Gulf of California Midriff Island Region into Southern California, but the expansion fluctuates from year to year. A strong inverse relationship between nesting pairs in three Southern California nesting …
The Regional State of Coast Report for the western Indian Ocean (WIO) is the first comprehensive regional synthesis to provide insights into the enormous economic potential around the WIO, the consequential demand for marine ecosystem goods and services to match the increasing human population, the pace and scale of environmental …
The growing human population must be fed, but historic land-based systems struggle to meet expanding demand. Marine production supports some of the world’s poorest people but increasingly provides for the needs of the affluent, either directly by fishing or via fodder based feeds for marine and terrestrial farming. Here we …
Environmental management inevitably involves trade-offs among different objectives, values, and stakeholders. Most evaluations of such trade-offs involve monetary valuation or calculation of aggregate production of ecosystem services, which can mask individual winners and losers. We combine a participatory, modeling, and scenarios approach to identify social–ecological trade-offs in a tropical fishery …
Rotational harvesting is one of the oldest management strategies applied to terrestrial and marine natural resources, with crop rotations dating back to the time of the Roman Empire. The efficacy of this strategy for sessile marine species is of considerable interest given that these resources are vital to underpin food …
Judgement of the National Green Tribunal (Western Zone Bench, Pune) in the matter of Oil & Natural Gas Corporation Ltd Vs Ramdas Janardan Koli dated 21/04/2015 regarding environmental damages caused due to expansion of the Port activities of JNPT and development activities of CIDCO and the spillage of oil by …
European continental shelf seas have experienced intense warming over the past 30 years. In the North Sea, fish have been comprehensively monitored throughout this period and resulting data provide a unique record of changes in distribution and abundance in response to climate change. We use these data to demonstrate the …
A variety of hydrokinetic turbines are currently under development for power generation in rivers, tidal straits and ocean currents. Because some of these turbines are large, with rapidly moving rotor blades, the risk of collision with aquatic animals has been brought to attention. The behavior and fate of animals that …
