Fishing Green: Calif. Harvested Wetfish Fisheries are the most efficient in the world

As more Californians consider their total carbon footprint, as a way to reduce human impacts on climate change, more are looking at “food miles”:  how far their food travels between the time it is harvested and the time it gets to their plate. The Farm-to-Fork movement not only implies freshness, but that transportation from the farm to the consumer’s plate is a relatively short distance.Fishing, like farming, can be green and sustainable. And California is leading the way in this effort, but distance is a misleading measure. Fishing green implies that fisheries are harvested at a sustainable level, keeping the fish populations healthy, while providing nutritious foods to millions of Americans and others worldwide. Beyond fishing below set quotas, there are three ways that fishing green can be achieved:• Reduce the harvest of foods that have high energy costs in their production, capture or transportation• Reduce harvest of high trophic level species that require a large amount of primary production to replace their numbers• Support efficiency in the production of fishery resourcesIn the complete “Fishing Green” report by Richard Parrish, PhD, you will learn more about how California’s wetfish fisheries (coastal pelagic species such as sardine, mackerel and market squid) are among the most sustainable methods of food production.  Purse-Seine fisheries for small pelagic fishes and squid in California are the most fuel-efficient of all the fisheries, averaging 6 gallons per metric ton harvested.Read more in the full report here.

Time to Take Ocean Acidification Seriously?

     November 22, 2013 -- HUMANS, being a terrestrial species, are pleased to call their home “Earth”. A more honest name might be “Sea”, as more than seven-tenths of the planet’s surface is covered with salt water. Moreover, this water houses algae, bacteria (known as cyanobacteria) and plants that generate about half the oxygen in the atmosphere. And it also provides seafood—at least 15% of the protein eaten by 60% of the planet’s human population, an industry worth $218 billion a year. Its well-being is therefore of direct concern even to landlubbers.That well-being, some fear, is under threat from the increasing amount of carbon dioxide in the atmosphere, a consequence of industrialisation. This concern is separate from anything caused by the role of CO2 as a climate-changing greenhouse gas. It is a result of the fact that CO2, when dissolved in water, creates an acid.That matters, because many creatures which live in the ocean have shells or skeletons made of stuff that dissolves in acid. The more acidic the sea, the harder they have to work to keep their shells and skeletons intact. On the other hand, oceanic plants, cyanobacteria and algae, which use CO2 for photosynthesis, might rather like a world where more of that gas is dissolved in the water they live in—a gain, rather than a loss, to ocean productivity.Read story from Saving Seafood here.Read story from The Economist here.

Ocean acidification progressing at an alarming rate

SEAFOOD.COM NEWS [BBC] By Matt McGrath - November 15, 2013 -The world's oceans are becoming acidic at an "unprecedented rate" and may be souring more rapidly than at any time in the past 300 million years.In their strongest statement yet on this issue, scientists say acidification could increase by 170% by 2100. They say that some 30% of ocean species are unlikely to survive in these conditions.The researchers conclude that human emissions of CO2 are clearly to blame.The study will be presented at global climate talks in Poland next week.In 2012, over 500 of the world's leading experts on ocean acidification gathered in California.Led by the International Biosphere-Geosphere Programme, a review of the state of the science has now been published.This Summary for Policymakers states with "very high confidence" that increasing acidification is caused by human activities which are adding 24 million tonnes of CO2 to oceans every day.Read the full article here.

State-of-the-art fishery research vessel Reuben Lasker completed for NOAA to commission in 2014

SEAFOOD.COM NEWS [seafoodnews.com] November 13, 2013 - NOAA has taken delivery of Reuben Lasker, the agency’s newest high-tech fisheries survey vessel from Marinette Marine Corporation, a Fincantieri company. The 208-ft. ship will primarily support fish, marine mammals and turtle surveys off the U.S. West Coast and in the eastern tropical Pacific Ocean.“Reuben Lasker represents a significant milestone in the agency’s efforts to provide world-class marine science platforms,” said Rear Adm. Michael S. Devany, director of the NOAA Office of Marine and Aviation Operations and the NOAA Corps. “This state-of-the-art ship will play a key role in supporting NOAA’s mission and serving the nation.”Built at MMC’s shipyard in Marinette, Wisc., and funded through the American Recovery and Reinvestment Act, Reuben Lasker is the fifth in a series of Oscar Dyson-class ships built for the agency. The ship is equipped with the latest technology for fisheries and oceanographic research, including advanced navigation systems, acoustic sensors, and scientific sampling gear.“MMC has a long, established history of delivering exceptionally crafted and complex vessels,” said Chuck Goddard, MMC’s president and CEO. “The talented and skilled workers of MMC are proud to deliver this high quality vessel to NOAA in support of its important mission.”The ship is also engineered to produce much less noise than other survey vessels, allowing scientists to study fish populations and collect oceanographic data with fewer effects on fish and marine mammal behavior. The ship’s comprehensive environmental sampling capabilities will enable researchers to gather a broad suite of marine life data with unprecedented accuracy.Read the full article here.

Helicopter ride reveals enormous mass of anchovies, herded by dolphins and whales

When small fish are threatened by large fish or much larger marine mammals in the open ocean, instinct demands that the small fish group together to try to appear larger as a group.But it’s not often that one of these swirling bait balls contains perhaps millions of anchovies and is large enough to dwarf, by many times, some of the largest predators to roam the ocean.Nor is it often that a photographer and videographer just happen to be flying overhead when one of these remarkable spectacles plays out.The accompanying image was captured this week off Ventura, California, by Liz Vernand, who was a passenger with Channel Islands Helicopters.Read the full article here.http://www.youtube.com/watch?v=sA64NZcE8HA

Eastern Steller sea lions removed from Endangered Species Act list

SEAFOOD.COM NEWS [Cordova Times] By Margarate Bauman - October 24, 2013 - Steller sea lions within the eastern distinct population segment, east of Prince William Sound, will be removed from the Endangered Species Act list, Jim Balsiger, administrator for NOAA Fisheries' Alaska region said Oct. 23.This is the first species NOAA has delisted, citing recovery, since the eastern North Pacific gray whale was taken off the list of threatened and endangered species in 1994.The delisting will take effect 30 days after publication of the final rule in the Federal Register.Balsiger said the agency is delighted to see the recover of this population segment of Steller sea lions, and that they would work with the states and other partners to monitor the population to ensure its continued health.NOAA officials said delisting is warranted because the species has met the recovery criteria outlined in its 2008 recovery plan and no longer meets the definition of a threatened or endangered species under the act.Best available scientific information indicates the eastern Steller sea lion population has increased from an estimated 18.040 animals in 1979 to an estimated 70,174 animals in 2010, the most recent year for which data are available.Eastern Steller sea lions will continue to be protected under the Marine Mammal Protection Act. With delisting, federal agencies proposing actions that may affect the eastern Steller sea lions are no longer required to consult with NOAA Fisheries under Section 7 of the ESA. NOAA Fisheries will continue to monitor the effects of proposed projects on the eastern population to ensure existing measures under the Marine Mammals Protection Act provide necessary protection to maintain recovery status, Balsiger said.NOAA has developed a post-delisting monitoring plan for this population. As a precautionary measure, the plan will be in effect for a decade, twice the required five year time period under the ESA.Read the full story here.

British study debunks mercury in fish risk for pregnant women

New research from the Children of the 90s study at the University of Bristol suggests that fish accounts for only seven per cent of mercury levels in the human body.In an analysis of 103 food and drink items consumed by 4,484 women during pregnancy, researchers found that the 103 items together accounted for less than 17 per cent of total mercury levels in the body.Concerns about the negative effects of mercury on fetal development have led to official advice warning against eating too much fish during pregnancy. This new finding, published today in Environmental Health Perspectives, suggests that those guidelines may need to be reviewed.Previous research by Children of the 90s has shown that eating fish during pregnancy has a positive effect on the IQ and eyesight of the developing child, when tested later in life. Exactly what causes this is not proven, but fish contains many beneficial components including iodine and omega-3 fatty acids.After fish (white fish and oily fish) the foodstuffs associated with the highest mercury blood levels were herbal teas and alcohol, with wine having higher levels than beer. The herbal teas were an unexpected finding and possibly due to the fact that herbal teas can be contaminated with toxins. Another surprise finding was that the women with the highest mercury levels tended to be older, have attended university, to be in professional or managerial jobs, to own their own home, and to be expecting their first child.Overall, however, fewer than one per cent of women had mercury levels higher than the maximum level recommended by the US National Research Council. There is no official safe level in the UK.Read the full article here.
