Scientists have for the first time calculated the likely impact of climate change on the distribution of more than 1000 species of fish around the globe.
As species shift northwards, their predictions for the North Sea include a 20 per cent reduction in Atlantic cod but a 10 per cent rise in the more southerly European Plaice.

Wild mackerel tastes better than the farmed variety. At least, it does if the origin is on the label. But a consumer who doesn't know where it's from will taste no difference. This is the claim made by Adriaan Kole in Food and Quality Preference. 'Taste is made up of two elements: what you taste on the tongue, and what you see and hear. The two combine to form the idea of 'tasty' in your mind' , says Kole, a researcher at the Centre for...

The aquaculture veterinarian invited to join the State Government's taskforce investigating two-headed fish larvae at a hatchery near the Noosa River remains convinced that exposure to toxic chemicals from neighbouring macadamia orchards is the "most probable explanation". Future Fisheries Veterinary Services principal Dr Matt Landos, who has been investigating the fish larvae deformities at Gwen Gilson's Sunland Freshwater Fish Hatchery at Boreen Point, said the...

An international team of researchers has proposed a revolutionary strategy for ending the plunder of the world's coral reefs and destruction of their fish stocks - beating poverty.
In a major study released today of the western Indian Ocean the team shows that reef fisheries are in far better condition where the society is more highly developed or where there is little or no development - than in places where the society is developing.
Most studies about the human impacts on...

Two saltwater superstars-cobia and Florida pompano-are regarded by connoisseurs as being some of the world's best seafood. Both cobia (pronounced COE-bee-uh) and pompano (POM-puh-no) have firm, mostly white flesh that's perfect for grilling, pan-frying or baking.
Now, Agricultural Research Service (ARS) agricultural engineer Timothy J. Pfeiffer, fish nutritionist Martin A. Riche, and fish biologist Charles R. Weirich-all based in Ft. Pierce, Fla.-are determining how to best raise...

Lorries transporting consignments of fish into the European Union will soon have to document where the fish originates from.
The reason for this is new EU regulations, which come into force on January 1, 2010.
The new regulations stipulate that all fish being exported to an EU country must be able to be traced back to its place of origin.
Pursuant to the regulations, a catch certificate must be produced for each consignment documenting where the fish...

Fresh research shows it is best to be careful with the use of salt in fry production.
The addition of saltwater should be limited to a salt content of 15 parts per thousand.
Earlier studies indicate that more than half of all fry producers add saltwater.
However, a scientific basis for this practice has been lacking. To the contrary, earlier research has implied potential harmful effects of using too much saltwater.

Nemo, the lovable clownfish of movie fame, may be unable to find his way home as the world's oceans acidify due to human carbon emissions.
Fish lose the sense of smell that guides them home when sea water becomes more acidic - with potentially devastating consequences for sea life, an international team of scientists has discovered.
Like many reef and coastal fish, Nemos are swept off their home reef into the open ocean as tiny babies and use their acute sense of smell to...

While many of the world's fisheries are in serious decline, the coastal Mediterranean fishery off the Nile Delta has expanded dramatically since the 1980s.
The surprising cause of this expansion, which followed a collapse of the fishery after completion of the Aswan High Dam in 1965, is run-off of fertilizers and sewage discharges in the region, according to a researcher at the University of Rhode Island Graduate School of Oceanography.
Autumn Oczkowski, a URI doctoral...

A synthetic chemical version of what male sea lampreys use to attract spawning females can lure them into traps and foil the mating process of the destructive invasive species, according to Michigan State University scientists.
Pheromones, chemical scents used to attract a mate, are well-documented in the insect world. Weiming Li, MSU professor of fisheries and wildlife, has focused much of his career on the well-developed sense of smell of the sea lamprey. In 2002, after four years...

Research published today reveals the major influence of fish on maintaining the delicate pH balance of our oceans, vital for the health of coral reefs and other marine life.
The discovery, made by a team of scientists from the UK, US and Canada, could help solve a mystery that has puzzled marine chemists for decades. Published today (16 January 2009) in Science , the study provides new insights into the marine carbon cycle, which is undergoing rapid change as a result of...

Are there really plenty of fish in the sea? University of British Columbia fisheries researcher Villy Christensen gives the first-ever estimate of total fish biomass in our oceans: Two billion tonnes.
And fish play a previously unrecognized but significant role in mitigating climate change by maintaining the delicate pH balance of the oceans, according to a study published in tomorrow's edition of the journal Science , co-authored by Christensen and a team of international...

A Spanish research team has researched and described for the first time in Europe the spread of the invasive dojo loach (Misgurnus anguillicaudatus) fish species. The fish comes from East Asia and was first discovered in the Ebro delta in 2001. Since then, it has occupied various parts of the river during its lightning spread, and is now definitively established. The researchers do not rule out that it could occupy new areas within coming years and threaten the survival of native species....

It may be tough for old dogs to learn new tricks, but a thirst for knowledge has led a Hancock man with years of experience harvesting marine resources to invent a new way for growing mussels.
Norman Hodgkins describes himself as "a professional worm digger" who has worked the Hancock County flats for a decade. Before that, however, Hodgkins was a diver, harvesting scallops and sea urchins and that's really where the story of his novel mussel growing device...

New trials funded by Seafish show that the flesh from scallop, whelk and crab waste can be used as commercial bait for the potting sector, and could turn disposal costs of £30 to £60 per tonne into a cost-neutral or profit making opportunity.
"The shellfish processing sector has a major waste disposal problem. UK production of waste from calcareous shellfish is around 75,000 tonnes per year, of which potentially 20,000 tonnes is flesh. Disposing of this waste is...

HB Grandi, one of Iceland's largest trawler firms. has boosted its supply of New Year cod from a new source - its aquaculture facility at Berufjörður on the island.
Around 50 tonnes of high quality cod were taken from the fish farm to the company's at Akranes and shipped to overseas markets by air where they are already appearing in chiller cabinets in supermarkets. The development reflects Iceland's decision to step up production of farmed cod in particular because...

A mix of strong winds, rough seas and frigid surface air and sea temperatures created the dangerous icing conditions that sank the New Bedford fishing vessel Lady of Grace in Nantucket Sound on the night of Jan. 26, 2007. All four fishermen onboard the vessel died at sea.
Scientists at UMass Dartmouth's School for Marine Science and Technology and the Woods Hole Oceanographic Institution have developed a new technology they hope will prevent another tragedy caused by icing...

NOAA has established eight separate marine protected areas encompassing a total of 529 square nautical miles in south Atlantic federal waters to shield deep-water fish species and their habitats from fishing.
All fishing for snappers, groupers, tilefishes, grunts, porgies, and sea basses is prohibited throughout the protected areas, which are located off the coast from North Carolina south to Florida.
The South Atlantic Fishery Management Council proposed the action to NOAA's...

Aquaponics is a bio-integrated system that links recirculating aquaculture with hydroponic vegetable, flower, or herb production. Recent advances by researchers and growers alike have turned aquaponics into a working model of sustainable food production. This publication provides an overview of aquaponics with brief profiles of working units around the country. An extensive list of resources point the reader to print and web-based educational materials for further technical...
