Climate and fishing steer ecosystem regeneration to uncertain economic futures

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 …

First record of abnormal fishes Epinephelus coioides and Cynoglossus cynoglossus from the south-east coast of India

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 …

Reconsidering ocean calamities

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. …

Adaptive potential of a Pacific salmon challenged by climate change

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 …

A century of fish biomass decline in the ocean

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 …

Light pollution and impact of light pollution

Ecological light pollution comprises direct glare, chronically increased illumination and temporary, unexpected fluctuations in lighting. The sources of ecological light pollution are very various and found in nearly every ecosystem in the form of sky glow, illuminated buildings and towers, streetlights, fishing boats, security lights, lights on vehicles, flares on …

Call for national action plan for conservation of sharks

KARACHI: Speakers at a one-day workshop held here on Monday underlined the need for a national action plan for the conservation of sharks whose numbers have declined by 80 per cent over 15 years. Shark population, they said, was essential to the prevention of the breakdown of the marine ecosystem. …

Multiyear predictability of tropical marine productivity

Phytoplankton is at the base of the marine food web. Its carbon fixation, the net primary productivity (NPP), sustains most living marine resources. In regions like the tropical Pacific (30°N–30°S), natural fluctuations of NPP have large impacts on marine ecosystems including fisheries. The capacity to predict these natural variations would …

Handbook on fisheries statistics 2014

This, the twelfth edition of the `Handbook on Fisheries Statistics 2014’, contains useful information on various aspects of the fisheries sector. The importance of this sector in the socio economic development of the countries is well known. Not only is it a source of livelihood for over 14 million people, …

Carbon footprint of marine fisheries: life cycle analysis from Visakhapatnam

The contribution of marine fisheries in Visakhapatnam at all stages of its life cycle to climate change during 2010-2012 was studied by determining its carbon footprint. Pre-harvest phase included vessel construction and maintenance and provision of fishing gear; harvest phase included harvest from mechanized and motorized craft and post-harvest phase …

Towards a global map of natural capital: key ecosystem assets

The UN Environment Programme World Conservation Monitoring Centre (UNEP-WCMC) has produced a composite map of the marine and terrestrial ecosystem assets of the world. The map, published in the report titled ‘Towards a Global Map of Natural Capital: Key Ecosystem Assets,' combines a number of existing spatial data sets to …

Coasts at risk: an assessment of coastal risks and the role of environmental solutions

Tropical and small island developing States (SIDS) are most at risk from exposure and vulnerability to coastal hazards, according to ‘Coasts at Risk: An Assessment of Coastal Risks and the Role of Environmental Solutions.' The report uses an indicator-based approach to assess risks from exposure and vulnerability to coastal hazards …

Fish for the future: fisheries development and food security for Kiribati in an era of global climate change

The Republic of Kiribati is a vast South Pacific island group with one of the largest exclusive economic zones (EEZs) in the world. Kiribati waters support a wealth of marine fisheries activities. These activities occur in oceanic, coastal and inshore environments and range from large, foreign, industrial-scale oceanic fishing operations …

Status and Trends of Caribbean Coral Reefs (1970-2012)

The Caribbean is a sprawling sea of deep nutrient-poor waters punctuated by great oases of biomass production and diversity of species, otherwise known as coral reefs. These reef systems circumscribe the shallow seafloor surrounding islands and delimit the continental shelf edge abutting contiguous landmasses: They also populate sunken and receding …

Chronic and intensive bottom trawling impairs deep-sea biodiversity and ecosystem functioning

Deep-sea ecosystem processes play a key role in global functioning of the planet. These functions are largely dependent upon deep-sea biodiversity. Industrial fisheries, after the depletion of fish stocks and destruction of the marine habitats on continental shelves, are now rapidly moving deeper into the ocean interior. We show here …

State Dips in Marine Fish Landing Records, Says Study

The estimates of marine fish landings (MFL) in 2013 released by the Central Marine Fisheries Research Institute (CMFRI), Kochi, recorded a fall of 4 per cent from 2012. In 2013, 3.78 million tonnes were recorded against 3.94 million tonnes in 2012, which was an all-time high. Gujarat topped in the …

The voluntary guidelines for flag state performance, the 2009 FAO agreement on port state measures and other instruments combating IUU fishing

This document reports on the outcome of the Technical Consultation on Flag State Performance, concluded in February 2013, which adopted Voluntary Guidelines for Flag State Performance, and which are being presented herewith for endorsement by COFI. It also gives an overview of the progress and status of the 2009 FAO …

Seasonal distribution and historic trends in abundance of white sharks, carcharodon carcharias, in the Western North Atlantic Ocean

Despite recent advances in field research on white sharks (Carcharodon carcharias) in several regions around the world, opportunistic capture and sighting records remain the primary source of information on this species in the northwest Atlantic Ocean (NWA). Previous studies using limited datasets have suggested a precipitous decline in the abundance …

Green certification guidelines

The Central Marine Fisheries Research Centre (CMFRI) and Marine Products Export Development Authority (MPEDA) could jointly draw green certification guidelines for marine ornamental fish breeding and reduce dependence on wild collection from coral reef habitations, CMFRI Director A. Gopalakrishnan has said. On the sidelines of a training programme at the …

The state of world fisheries and aquaculture 2014
