IN BRIEF - Massachusetts prohibit the sale of escolar
Friday, January 18, 2013
Massachusetts would levy fines on supermarkets and restaurants that mislabel seafood and become the first state in the nation to ban the sale of escolar, an oily species known as the “ex-lax” fish that is often served as sushi, under legislation expected to be filed Friday.
The bill, proposed by the Legislature’s Joint Committee on Consumer Protection and Professional Licensure, comes more than a year after a Boston Globe report revealed widespread seafood substitution in restaurants across Massachusetts. In many instances, less desirable and cheaper species took the place of fresh local fish. A follow-up investigation published last fall found most of those restaurants were still mislabeling seafood.
Businesses caught misrepresenting fish such as Atlantic cod, Atlantic halibut, red snapper, or grey sole could face fines of up to $800 and have their license to operate suspended or revoked after repeat offenses, according to the legislation.
The law would also prohibit the sale of escolar, frequently mislabeled as white tuna or albacore at sushi restaurants, and punish first-time violators with a minimum $400 fine or license suspension. Albacore, a white tuna desired for its mild taste, is not related to escolar and typically costs 20 percent more.
Officials have confirmed the deadly whirling disease, which affects fish, has been found at six more locations in waterways near Banff National Park.
"Clearly, having the disease fairly well established in Banff National Park isn't positive news," Roger Ramcharita, a regional director for Alberta Environment and Parks.
"We're still very hopeful that the incidences of whirling disease hasn't spread throughout the Bow [River] system."
Posted to the Canadian Food Inspection Agency website on Monday, the six latest locations include:
-Spray River upstream from the confluence of the Cascade River and Cascade Creek. -Cascade Creek upstream from the confluence of the Cascade River and Cascade Creek. -Carrot Creek upstream of the confluence of Cascade River and Cascade Creek. -Bow River near Tunnel Mountain. -Lower Cascade River upstream from the confluence of the Bow River and the Cascade River. -Bow River downstream from the confluence of the Bow River and Carrot Creek.
Many of the ecosystems most impacted by human activities, such as tropical forests and coral reefs, are also among the most biodiverse in the world. But a recent study determined that conserving biodiversity may not be enough to ensure coral reefs rebound from the impacts of exploitation by mankind.
In coral reef ecosystems, fish typically constitute a substantial portion of living biomass and thus represent an important reservoir of nutrients. So it makes sense that the removal of biomass via fishing impacts the nutrient capacity of coral reefs.
And because nutrient inputs from outside reef systems are scarce, the replacement of nutrients removed by fishing occurs at a slow rate — “a dynamic that is analogous to the disruption of nutrient cycles in tropical rainforests following intensive timber harvest,” according to an article published in the journal Nature Communications in August 2016.
But it is unknown exactly how much fishing — and, in particular, the selective exploitation of certain species — impacts the fish nutrient capacity of coral reef ecosystems, the authors of the article, a team led by Jacob Allgeier of the University of Washington, Seattle’s School of Aquatic and Fisheries Science, write in the article.
A study by Eawag and Zurich University researchers using a new imaging method has revealed that, surprisingly, cocaine accumulates in the eyes of zebrafish. The findings indicate that chemicals -- especially psychoactive drugs -- need to be assessed quite differently with waterborne exposure than, for example, when pharmaceutical substances are tested in mice. In particular, the uptake mechanisms and effects of cocaine in fish cannot simply be transferred to mammals or humans.
Zebrafish larvae a few days old are frequently used in toxicology tests -- e.g. to study the behavioural effects of drugs -- in order to avoid experiments in mammals. Taking the example of cocaine, researchers at Eawag, together with colleagues at Zurich University, have now shown that the uptake and distribution patterns and the effects of the drug in zebrafish differ in many ways from those in mammals. In their study, a complex imaging method (MALDI MSI[i]) was used for the first time to determine where cocaine accumulates in zebrafish. After being exposed to a defined concentration of the drug for eight hours, the larvae were euthanized and frozen. Tissue samples a few micrometres thick were then imaged by laser scanning.
The images show that the greatest accumulation of cocaine is to be found, not in the brain, but in the eyes, where concentrations over 1500 mg/kg were measured -- compared to around 300-400 mg/kg in the trunk and brain. This finding is striking: while increased concentrations have been observed in the head region in other fish studies, the highest concentrations were assumed (without more precise measurements) to occur in the brain. In addition, compared to mammals, these levels are very high: in mice, concentrations 100 times lower are generally lethal, and in humans, 1000 times lower. Environmental toxicologist Kristin Schirmer, who co-led the project with Thomas Kraemer of the Zurich Institute of Forensic Medicine, cannot yet fully explain their findings. It is, however, clear that cocaine is taken up rapidly and continuously by zebrafish larvae, which at this early stage have not yet a fully developed blood-brain barrier.
SEATTLE - A new study finds that unusually warm Pacific Ocean temperatures helped cause a massive bloom of toxic algae in 2015 that closed lucrative fisheries from California to British Columbia and disrupted marine life from seabirds to sea lions.
Scientists linked the large patch of warm ocean water, nicknamed the "blob," to the vast ribbon of toxic algae that flourished in 2015 and produced record-breaking levels of a neurotoxin that is harmful to people, fish and marine life.
The outbreak of the toxin domoic acid, the largest ever recorded on the West Coast, closed razor clam seasons in Washington and Oregon and delayed lucrative Dungeness crab fisheries along the coast. High levels were also detected in many stranded marine mammals.
"We're not surprised now having looked at the data, but our study is the first to demonstrate that linkage," said Ryan McCabe, lead author and a research scientist at the University of Washington's Joint Institute for the Study of the Atmosphere and Ocean. "It's the first question that everyone was asking."
The public are being asked to back proposals to create new marine wildlife havens off the Fylde coast. The Wildlife Trust has called on Government to improve protection for threatened marine species by increasing the number of Marine Conservation Zones around he UK.
A list of 48 sites around the UK has been put forward by the Trust including three off Lancashire which would help improve conditions in spawning grounds in the Wyre, Ribble and Lune estuaries. The trust hopes that if all 48 zones it will complete a network of special places where habitats and wildlife can flourish to safeguard healthy and productive seas for the future.
The proposals would limit some trawler activity – a move which may not be popular with fishing industry bosses already concerned by the encroachment of wind farms on fishing grounds.
US government's decision to roll back the hike in anti-dumping duty on shrimp imports from India will benefit the country's farmers and lead to higher production, rating agency Icra said today.
"... The impact of any hike/decline in duty/tax will be passed on back to the farmers by the processors, and not to the end consumer.
"Hence, while farmers bear the price-risk, they stand to benefit from the current reduction in duty levels. This could lead to increase in sowing and higher shrimp production in the near term," Icra said in a report.
The US Department of Commerce (US DoC) in its 10th annual review had increased the weighted average anti-dumping duty (ADD) on shrimp imports from India to 4.98 per cent up from 2.96 per cent.
An inspection of Supervalu’s facility in August found 21 instances where seafood was stored at too high a temperature, according to the letter. FDA also found fault with Supervalu’s monitoring procedures and corrective action plan, as well as gaps in the loading bay doors of receiving and distribution areas. As a result, FDA deemed Supervalu’s products at the seafood facility to be adulterated.
The letter states that Supervalu responded to the inspection observations in early September 2016, but FDA found that response to be inadequate.
Vietnamese investors, currently on a one-week working visit to Ghana, are seeking to establish joint ventures with Ghanaian partners in the production of tilapia, cashew and rice.
At a Ghana-Vietnam Business Forum held in Accra, on Tuesday, Dao Manh Duc, who is the second Head of Trade, Embassy of the Socialist Republic of Vietnam in Nigeria, said the team is looking for opportunities in production, processing, and marketing of the said products.
The visit, facilitated by the Vietnamese Ministry of Agriculture and Rural Development and the Ghana-Vietnam Chamber of Commerce and Industry, was initiated for both parties to strengthen the existing trade relations.
First 'marine monument' created in the Atlantic United States
The United States Government has created the Atlantic Ocean's first marine national monument, saying that the new protected area was a needed response to risky climate changes, ocean dead zones and unsustainable fishing practices.
