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 security and maintain the social and economic wellbeing of small-scale and commercial fishers globally.

Question raised in Rajya Sabha on impact of climate change on fishing communities, 30/04/2015.

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 faulty maintenance of the pipeline in Tal. Uran, District Raigad, Maharashtra which also has contributed to loss of environment and ecology.

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 remarkable power of generalized additive models (GAMs), trained on data earlier in the time series, to reliably predict trends in distribution and abundance in later years.

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 approach such large hydrokinetic turbines have not yet been monitored at any detail. In this paper, we conduct a synthesis of the current knowledge and understanding of hydrokinetic turbine collision risks.

Overfishing of large predatory fish populations has resulted in lasting restructurings of entire marine food webs worldwide, with serious socio-economic consequences. Fortunately, some degraded ecosystems show signs of recovery. A key challenge for ecosystem management is to anticipate the degree to which recovery is possible. By applying a statistical food-web model, using the Baltic Sea as a case study, we show that under current temperature and salinity conditions, complete recovery of this heavily altered ecosystem will be impossible.

The first record of morphologically abnormal wild fishes, Epinephelus coioides (Hamilton, 1822) and Cynoglossus cynoglossus (Hamilton, 1822), in the Parangipettai and Nallavadu landing centres along the south-east coast of India were reported. The caudal region of both of the fishes was completely deformed and fused. These abnormalities have been considered as an important indicator of environmentally induced stress to the wild fishes.

The proliferation of a number of pressures affecting the ocean is leading to a growing concern that the state of the ocean is compromised, which is driving society into pessimism. Ocean calamities are disruptive changes to ocean ecosystems that have profound impacts and that are widespread or global in scope.

Pacific salmon provide critical sustenance for millions of people worldwide and have far-reaching impacts on the productivity of ecosystems. Rising temperatures now threaten the persistence of these important fishes, yet it remains unknown whether populations can adapt. Here, we provide the first evidence that a Pacific salmon has both physiological and genetic capacities to increase its thermal tolerance in response to rising temperatures.

The researchers performed a global assessment of how fish biomass has changed over the last 100 years, applying a previously developed methodology using ecological modeling. Our assessment built on more than 200 food web models representing marine ecosystems throughout the world covering the period from 1880 yo 2007. All models were constructed based on the same approach, and have been previously documented.
