As you report (BusinessDay, July 26-27), who should control fisheries isn't simple. Economically, rational fisheries management doesn't always equal sustainable use and would seldom equal sustainable management of the ecosystem those fish live in. For many fish that are slow-breeding, long-lived and in deep water, mining of the resource makes economic sense. Profits can then go into other businesses or mining of new fish stocks. And even where sustainable use makes sense economically, the...

By HYWEL TREWYN LOBSTER fishermen on the Lly'n Peninsula fear losing their livelihoods if plans for "no take" zones by conservationists go ahead. The draft Marine Bill - now out to consultation - proposes to manage the marine environment "in a better way" as part of the Government's commitment to improving nature conservation at sea. However Lly'n Pot Fishermen's Association fears the Bill will mean establishing "notake" zones stopping them potting for lobster, crab, prawn and whelks....

The Lyme Bay exclusion zone is to be monitored by Westcountry scientists after they won a major pounds400,000 Defra contract. The scientists, led by marine biologists from the University of Plymouth, will now monitor the ecological and socio-economic impact of the 60 sq m exclusion zone. Almost 10 per cent of Lyme Bay, one of Britain's richest marine habitats, has been permanently closed off to scallop dredging and bottom trawling in a bid to protect the area's reef habitats. The move,...

By Ian Johnston Sturgeon stroll to the Humber aims to raise sights on fish conservation Environmentalists seeking to highlight the decimation of the UK's larger fish species are to make a symbolic journey from the headwaters of the Trent to the Humber Estuary, once a thriving spawning ground for sturgeon. Lisa Chilton, marine development manager for the Wildlife Trusts, said: "We don't think of sturgeon as a UK species, but not so long ago they were common and still part of our diet."...

By Jacqueline L. Urgo, The Philadelphia Inquirer Jul. 13--ATLANTIC CITY -- The temperatures may be steamy outside, but, baby, it's cold in the water. Just ask Melinda Castile, down the Shore for a week from Brooklyn, N.Y., and determined to go in the ocean no matter what the temperature. She bought a wetsuit. "I know it looks weird, but too bad. The water's freezing," said Castile, 28, as she emerged from the chilly surf near the Brighton Avenue beach. Then there was Lacy Julius, 3,...

By Winston Ross, The Register-Guard, Eugene, Ore. Jun. 13--West Coast groundfishermen can expect a major change in the way they're allowed to catch fish in the coming years, after a preliminary decision Thursday from the Pacific Fishery Management Council. The council voted in favor of an individual quota system that will determine who gets to catch how many fish. Shares of the resource will be allocated, and can be traded, sold or kept for life. The decision isn't final unless...

Fishery biologist Sandy Sutherland looks through the lens of the microscope at tiny sections of fish earbones, known as otoliths, each showing annual bands of growth. She carefully counts the bands to determine the age of the fish, then moves on to the next sample.  Known as an age reader, Sutherland is one of a small team at NOAA's Northeast Fisheries Science Center (NEFSC) whose aging work is critical to stock assessments needed to manage the nation's fishery resources in the Northwest...

RV Polarstern finished first Antarctic field season within the International Polar YearThe Antarctic deep sea gets colder, which might stimulate the circulation of the oceanic water masses. This is the first result of the Polarstern expedition of the Alfred Wegener Institute for Polar and Marine Research in the Helmholtz Association that has just ended in Punta Arenas/Chile. At the same time satellite images from the Antarctic summer have shown the largest sea-ice extent on record. In the...

Federal research minister aboard the research icebreaker PolarsternIn the Southern Ocean, large quantities of surface-drifting plankton algae are able to significantly reduce the carbon dioxide content of the surface waters, which can affect the global carbon dioxide cycle. This is one of the results from an Antarctic expedition which has just drawn to a close in Cape Town on February 4, and which was led by the Alfred Wegener Institute, part of the Helmholtz Association. On February 5, an...

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

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...
