20/11/12: News stories on antibiotics, shrimp bans and Global GAP certification. Since the antibiotics that are used in veterinary medicine and aquaculture belong to the same group of antibiotics as those used in medicines for humans, increased resistance to these medicines will be detrimental to public health. Syed Qaswar Ali Shah's doctoral research project has studied the genetic foundation for resistance to antibiotics in bacteria isolated from salmon fish in Norway. He collected quinolone-resistant isolates of the bacterium Flavobacterium psychrophilum from rainbow trout and equivalent isolates of Yersinia ruckeri from Atlantic salmon. These bacteria are the cause of bacterial coldwater disease in rainbow trout and redmouth disease in salmon respectively.
Only a limited number of antibiotic agents are authorised for use in aquaculture. International Aquafeed Newsletter November 2012. 6th International Algae Congress Microalgae have been of major interest for producing biofuels in the last decade. Recently, development and focus was changed towards the use of microalgae in the food, feed, materials and chemical sector as well. The potential of micro algae and aquatic biomass is enormous. The developments follow each other in rapid succession. Microalgae contain high amounts of lipids, proteins and carbohydrates, which all can be used for different markets. For biofuels only, microalgae production appears to be too costly but in a biorefinery concept where the different compounds are isolated, algal biofuels remain a feasible option.
The GreenStars Project has the goal to develop by 2020 compounds of interest such as efficient biofuels and high added value substances with microalgae feeding on industrial emissions of carbon dioxide and nutrients contained in waste. Aquaculture 2013 - programme announced. Salmon lice case is not proven. A row erupted after St Andrews University claimed 39% of Atlantic salmon deaths were due to parasites, while salmon farmers, represented by the Scottish Salmon Producers Organisation (SSPO), said the figure is 1% to 2%. Both sides extrapolated their conclusions from near-identical data. The SSPO accused Scotland's oldest university of misleading the nation.

Norel. Staff, farm sites safe following British Columbia tsunami warning.
With storm Sandy dominating weather reports across the world this week, news of a 7.7 magnitude earthquake near Haida-Gwaii on Saturday has been sidelined. Preplanning, rapid communication and proactive measures protected farmers and fish this weekend as BC’s salmon farmers responded quickly to a tsunami warning for Vancouver Island’s west coast. Following the 7.7 magnitude earthquake near Haida-Gwaii on Saturday, salmon farmers voluntarily rolled out emergency preparedness protocols and moved staff from approximately 20 salmon farm sites located in the waters off the coast of British Columbia to predetermined safe locations. All staff members are safe and no damage has been reported on any farm sites. “Ensuring that our staff and farms are safe is of critical importance to our farmers,” said Mary Ellen Walling, Executive Director, BC Salmon Farmers Association.
“The proactive measures taken this weekend are an example of the high level of care we take to farm responsibly in the ocean.” Aquaculture 2013 - programme announced. We have just had a sneaky peek at the programme for Aquaculture 2013 in Nashville, USA, February 21-25, 2013. Shrimp will play a huge role with a host of sessions including nutrition, production and disease and health. As well as species sessions there will also be contributed sessions dedicated to current trends and management. I'm already looking forward learning more about urban aquaculture and harmful algal blooms. I am also pretty excited about some of the more unusual topics such as zebrafish, frogs and eels.
You can view the programme online and download the brochure here. Also, look out for our interview with event organisers in the November/December 2012 issue of International Aquafeed magazine.

The offshore aquaculture industry has requested that United Nations’ FAO conduct an assessment of the access and operational frameworks for open ocean mariculture in the High Seas, and make recommendations as to how to better encourage work towards mariculture in waters beyond any one nation’s EEZs.
A Statement to this effect was drafted at The Offshore Mariculture Conference, held in Izmir, Turkey, over three days from 17-19 October 2012 and the Turkish government offered to formally convey the request to FAO. The Statement adopted at the conclusion of the Conference drew from a number of preceding declarations – including the 2010 Global Conference on Aquaculture, the Phuket Consensus of 2010, and the Colombo Declaration of 2011, all of which have emphasized the critical role for aquaculture in feeding the world, stimulating economic development, providing employment and reducing existing negative impacts on the marine environment.

A marshal at San Juan Hills Golf Course found the leopard shark writhing around on the course and brought it to the clubhouse. Staff kept the shark in a bucket of salty water and then returned it to the ocean during a lunch break. It is believed the shark had been snatched up by a large bird of prey, such as an osprey or peregrine falcon, which then lost its grip on its dinner. Two bleeding puncture marks were seen near the fish's dorsal fin. Read more... Buhler. 22/10/12: Samoa aquaculture grant; tilapia in Canadain high school; FDA approved drugs.

Marine finfish like Atlantic salmon are raised in net pens like these (Photo Credit: USDA) Madi Gamble was the Ocean Conservation intern this summer at CLF.
She grew up fishing in Marblehead, MA and is now a senior at Dartmouth College, where she studies biology and environmental science. This piece is the second in a series focused on aquaculture, both world-wide and in New England. The term “aquaculture” refers to a broader spectrum of practices than many realize. In freshwater and marine ecosystems, finfish and shellfish are raised in a variety of different man-made structures. Mesh nets, lines, cages, and rafts are used for shellfish aquaculture, which in New England produces mostly mussels, clams, and oysters. Saltwater finfish aquaculture, which in New England consists mostly of salmon farming in Maine, is carried out in large net-cages placed in coastal marine waters, which are stocked with fry from freshwater hatcheries on land. Final hurdle for fish farm expansion. Updated Tue 9 Oct 2012, 11:54am AEDT The Federal Environment Minister, Tony Burke, has approved a massive expansion of fish farming at Macquarie Harbour in Tasmania's west.
Salmon farmers Tassal, Huon Aquaculture and Petuna are expanding their marine leases in the harbour to nine square kilometres. The companies won State Government approval for the expansion in May and say a Federal Government review has made almost no changes to the plan. Tassal managing director Mark Ryan says the move will allow his company to vastly increase production but he cannot yet say how many new staff his company will employ.
"At the moment, until we've got board approval for it, we're not going to go through all the numbers other than to say we'll significantly increase our production coming out of Macquarie Harbour," he said. "Ultimately it could be as much as double. " State Resources Minister Bryan Green says the expansion will provide an economic boost to the region.

Washington Pew applauds action to ban shark fishing in critical breeding habitat Resources:Press photos Venezuela set forth a series of measures this week to protect sharks within its waters.
Most significantly, commercial shark fishing is now prohibited throughout the 3,730 square kilometers (1,440 square miles) of the Caribbean Sea that make up the popular Los Roques and Las Aves archipelagos, whose pristine beaches and coral reefs make it a diving and fishing attraction. Scientists have identified Los Roques, located about 128 kilometers (80 miles) off the Venezuelan coast, as an important breeding ground and nursery for populations of several species of sharks, including the lemon shark and the Caribbean reef shark. The new regulation also prohibits the practice of shark finning (cutting off the fins and dumping the body overboard at sea) and mandates that all of these animals caught in Venezuelan waters must be brought to port with their fins naturally attached.

But should we believe these reports? What do the experts say about the numbers of fish that are left? The Daily Telegraph recently ran the headline: "Just 100 cod left in the North Sea". "It just makes my blood boil - 100 cod in the North Sea? " It's not a trivial issue. The story was picked up by other media, including the Atlantic Wire and Canada's Globe and Mail, but it started in the The Sunday Times which reported there were "100 adult cod in North Sea".
The newspaper got the figure by looking at data from the International Council for the Exploration of the Sea (ICES). It then asked researchers from the British government's Centre for Environment, Fisheries and Aquaculture Science (Cefas) for help with the numbers. The Sunday Times chose to class an adult cod as aged over 13. Continue reading the main story Source: ICES. Aquafeed Industry Events | International Aquafeed Magazine.
