WASHINGTON, Dec. 21 /PRNewswire-USNewswire/ -- Catch share programs result in more consistent and predictable fisheries but do not necessarily improve ecological conditions, according to a new study published online this week by the journal Proceedings of the National Academy of Sciences. Employed by nations around the world, catch shares - a management system that divides up and allocates percentages, or shares, of the total allowable catch to individual fishermen or fishing groups - have...

WASHINGTON, Dec. 10 /PRNewswire-USNewswire/ -- Lee Crockett, director of Federal Fisheries Policy at the Pew Environment Group, today issued the following statement in response to the National Oceanic and Atmospheric Administration's (NOAA) release of its draft policy on the use of catch shares in federal fisheries. "NOAA and its Catch Shares Task Force recognize that catch shares are not a one-size-fits-all fisheries solution and not all fisheries can or should be managed by them. In...

Studies conducted in California and elsewhere provide support for the use of marine reserves as a tool for managing fisheries and protecting marine habitats, according to biologists at the University of California, Santa Cruz. A recent study in the Gulf of California, for example, confirmed the validity of a key concept behind marine reserves--the idea that offspring produced in a protected area can replenish the stocks of harvested species outside the reserve. "It seems really obvious, but...

Nutrients in the Atlantic Large-scale distributions of two important nutrient pools "“ dissolved organic nitrogen and dissolved organic phosphorus (DON and DOP) have been systematically mapped for the first time over the Atlantic Ocean in a study led by Dr Sinhue Torres-Valdes of the National Oceanography Centre, Southampton. The findings have important implications for understanding nitrogen and phosphorus biogeochemical cycles and the biological carbon pump in the Atlantic Ocean. Tiny...

Southern Species like Atlantic Croaker May Become Common in New England Waters About half of 36 fish stocks in the Northwest Atlantic Ocean, many of them commercially valuable species, have been shifting northward over the last four decades, with some stocks nearly disappearing from U.S. waters as they move farther offshore, according to a new study by NOAA researchers. Their findings, published in the journal Marine Ecology Progress Series, show the impact of changing coastal and ocean...

An Australian method for assessing the environmental impact of marine fisheries has caught the eye of fishery management agencies worldwide. Aspects of the 'ecological risk assessment' (ERA) method have been adopted in the US, Canada, Ecuador, and the Western and Central Pacific, and by the international eco-labeling organization the Marine Stewardship Council. The method was developed in research led by Dr Tony Smith and Dr Alistair Hobday from CSIRO's Wealth from Oceans Flagship in...

Major shifts in fisheries distribution due to climate change will affect food security in tropical regions most adversely, according to a study led by the Sea Around Us Project at The University of British Columbia. In the first major study to examine the effects of climate change on ocean fisheries, a team of researchers from UBC and Princeton University finds that climate change will produce major shifts in productivity of the world's fisheries, affecting ocean food supply throughout the...

NOAA and Norwegian researchers recently completed a comparative analysis of marine ecosystems in the North Atlantic and North Pacific to see what factors support fisheries production, leading to new insights that could improve fishery management plans and the ecosystems. Known as MENU, for Marine Ecosystems of Norway and the U.S., the collaborative project involved scientists at the NOAA Fisheries Service's Northeast Fisheries Science Center and Alaska Fisheries Science Center and colleagues...

U.S. scientists say human impacts and environmental factors are changing the northwest Atlantic Ocean ecosystem. A study by the National Oceanic and Atmospheric Administration's Northeast Fisheries Science Center shows fish in U.S. waters from Cape Hatteras to the Canadian border have moved away from their traditional, long-time habitats during the past four decades because of fundamental changes in the regional ecosystem. NOAA's 2009 Ecosystem Status Report also notes the need to manage the...

Overfishing threatens many species but a combination of steps could turn that around, two groups long at odds with each other said. Marine ecologists and fisheries management scientists worked together for two years and published their findings Friday in the journal Science. The researchers agreed solutions to overfishing lie not only in management techniques but also in the political will to apply them, even if it initially causes economic disruption, said a release from the U.S. National...

Ocean Analysis for November 17, 2012
2012-11-17 08:24:58

Point #1: Warm finger- This region inside the area marked number 1, represents a warm finger of the ocean temperatures. What is occurring is that the warmer air is being pushed faster in this region than the surrounding locations giving us this little finger of warmer temps in that region. Point #2: Warm Eddie- This is a region of warmer temps surrounded on all sides by colder water. Eddies are a closed circulation of water in the ocean that has in this case warmer temps around it. These...

Ocean Current Impacts On Weather
2012-07-30 13:25:48

The Peru Current flows from South to North along the western side of South America. This current transports colder air from the south northward towards the equator. This current is responsible for bringing cooler waters off the coast of Peru which is a big reason that they have such high fishing success. However this current can get altered during EL-Nino when the warmer waters of the Pacific are transported west to east and start to replace these colder waters. The Peru current is...
