Michael Rubino takes on new role as NOAA Fisheries’ senior advisor for seafood strategy

April 30, 2019 — Dr. Michael Rubino has been appointed as the new senior advisor for seafood strategy at NOAA Fisheries, the agency announced on 29 April.

Rubino, who has served as the director of the Office of Aquaculture at NOAA Fisheries since 2011, will be in charge of leading the development of markets for U.S. fisheries products and oversee the expansion of new domestic aquaculture production in his new role. With a plethora of experience in seafood production and the science behind it, Rubino is an ideal fit for the new expanded position, according to NOAA Fisheries.

“We are thrilled that Michael is stepping into this new, expanded role,” Dr. Paul Doremus, the deputy assistant administrator for operations at NOAA Fisheries, said in a press release. “He has a wealth of experience leveraging partnerships across the seafood spectrum and will now play an even bigger role in the expansion of U.S. seafood production, economic growth, and new jobs.”

There will be two major responsibilities in store for Rubino as NOAA Fisheries’ new senior advisor for seafood strategy: First being to expand U.S. aquaculture production by forming partnerships with seafood companies, fishermen, seafood famers, scientists, government agencies, tribes, and others to support the adoption of sustainable aquaculture practices nationally; and secondly, helping to develop new markets for U.S. wild-capture fisheries, the agency said. To help fulfill these core responsibilities, Rubino will work closely with the Office of Aquaculture as it continues to lead the NOAA Fisheries’ work on aquaculture, and the Office of International Affairs and Seafood Inspection, as it continues to focus on market access and international trade.

MSC, ASC sustainable seafood week in France urges consumers to eat responsibly

April 30, 2019 — A joint campaign in France run by the Aquaculture Stewardship Council (ASC) and the Marine Stewardship Council (MSC), has just landed the two organizations a Grand Prix Award for Social Responsibility. It was presented during a ceremony in Paris at PRODURABLE, the fair for Sustainable Development and Corporate Social Responsibly.

The prize was awarded for “Semaine de la Peche Responsible” (Sustainable Seafood Week), which was first run in February 2017 and has since become an annual event.

The week of activities highlighted issues including overfishing, illegal fishing, and the importance of safeguarding marine biodiversity and habitats, and fish stocks for future generations. The event has been growing quickly in both size and public profile in recent years.

In competition with 48 other brands, the ASC and MSC were joint winners of the best NGO label category, in recognition of their collaborative efforts with partners, brands, aquariums, institutions and distributors, to mobilize public support for sustainable fisheries and responsible fish farming.

The award was shared with French retailer Carrefour, which won for its support of programs to find permanent living solutions for the homeless.

Cooke Aquaculture sends more boats to help flooded communities

April 26, 2019 — The following was released by Cooke Aquaculture:

Cooke Aquaculture has diverted three more boats and marine staff from its Charlotte County fish farming operations to help with flood relief efforts in Grand Bay-Westfield and the City of Saint John in New Brunswick.

This is in addition to the two boats the local, family-owned company already sent to the Village of Cambridge-Narrows on the Washademoak Lake this week. The motor boats are all 21-25 feet long, equipped with safety equipment and are run by trained Cooke Aquaculture operators accompanied by local first responders.

The New Brunswick Emergency Measures Organization (NBEMO) has advised the public that water levels have yet to reach their highest levels in a number of communities along the southern regions of the St. John River basin. And that residents living near the St. John River system should continue to exercise extreme caution and remain alert to rising water levels over the coming days.

“We encourage people to follow the Emergency Measures Organization advice to avoid boating, kayaking or other water activities this time of year as currents are strong and may carry debris,” said Joel Richardson, Vice President of Public Relations with Cooke Aquaculture. “In last years flood our boats retrieved everything from half-submerged building materials, gas cans, and tires to propane tanks from the water. People should stay away from the rivers and lakes until it is safer.”

US companies file class-action suit alleging price-fixing by Norwegian farmed salmon firms

April 25, 2019 — A class-action lawsuit filed on behalf of U.S. direct purchasers of Norwegian farmed salmon is accusing multiple Norwegian firms including Mowi, Grieg Seafood, Lerøy Seafood, and SalMar of conspiring to fix the prices of farmed salmon.

The lawsuit, filed on Tuesday, 23 April, alleges the major players in Norway’s farmed salmon industry exchanged competitively sensitive information among themselves, with the aim of artificially controlling the price of farm-raised salmon bought by U.S. seafood buyers, a violation of the Sherman Anti-Trust Act.

The lawsuit is largely based on an ongoing investigation by the European Commission into “suspected anti-competitive practices” in the farmed Atlantic salmon sector in Europe, first made public in February 2019. The investigation included raids by E.C. officials of the Scottish and Dutch corporate offices of several seafood companies based in Norway, including Mowi, Grieg Seafood, Lerøy Seafood, and SalMar.

A letter sent by the E.C. to one of the companies, obtained by SeafoodSource, revealed the E.C. approved a decision on 6 February, 2019, to investigate information received “from different actors operating at different levels in the salmon market” alleging that some Norwegian producers “participate or have participated in anti-competitive agreements and/or concerted practices related to different ways of price coordination in order to sustain and possibly increase prices of farmed Norwegian Atlantic salmon.”

The lawsuit was filed in U.S. District Court in the Southern District of Florida (Miami Division) on behalf of Mentor, Ohio-based Euclid Fish Company, according to Arthur Bailey of Hausfeld LLP, one of the plaintiffs’ attorneys. Numerous other similar suits have and will continue to be filed containing similar allegations, including by Schneider’s Seafood & Meats of Cheektowaga, New York, and by Euro USA Inc. of Cleveland, Ohio, Bailey told SeafoodSource. Within the next month, the cases will be combined into one larger class-action suit including all direct purchasers of Norwegian farmed salmon, Bailey said. The case will be heard by James Lawrence King.

Replacing fish-based aquaculture feed with plant-based increases environmental impacts

April 24, 2019 — The sustainability of farmed seafood is directly tied to how efficiently the animals turn their feed into flesh, aka food for people. Farms that use more feed to grow the same amount of food are more impactful than others. But what also matters is the kind of feed given to cultured species. Typically, fish and shrimp are fed fishmeal, a kind of feed made from ground-up fish. Fishmeal can be made from the excess trimmings of fish processing, but there are several wild-caught fisheries that only serve to be reduced into fishmeal for aquaculture, e.g. Peruvian anchoveta. However, with a growing market for farmed seafood, fishmeal is in high demand.

This has raised fishmeal prices worldwide; so some shrimp farms, most of which are in developing countries, have begun to substitute fishmeal with plant-based feeds. A recent paper in Sustainability, Malcorps et al. 2019, set out to measure the environmental and social impact of substituting fishmeal for plant-based feed in farmed shrimp. Currently, shrimp feeds are 20-30% fishmeal, depending on the shrimp species being farmed—what would the environmental impact be if those percentages dropped?

Malcorps et al. 2019 built a computer model to assess the changes in land, freshwater, and fertilizer use caused by substituting a portion of fishmeal shrimp feed with plant-based feed. The model found that substituting fishmeal with plant-based feed led to a dramatic increase in terrestrial resource demand for the 5 crops commonly used for substitution (wheat, soybeans, rapeseed, pea, and corn). A maximum plant-based substitution in shrimp feed would lead to a 63% increase in freshwater use, 81% increase in land use, and an 83% increase in phosphorus (fertilizer) relative to the current levels in those 5 crops.

Further, and more concerning, is the notion that increased demand on those 5 crops would raise prices and seriously impact poor families that rely on them for food.

Low consumer awareness of microplastics in fish, finds survey

April 15, 2019 — Forty percent of consumers are aware of the issue of microplastics in fish, according to a new survey conducted by land-based salmon farming company Pure Salmon. The recently-launched company’s analysis also found that 36.5 percent had knowledge of antibiotic use in sea-farmed fish.

The results are part of a survey of 2,000 consumers in the United Kingdom and United States. Consumers in each country were asked their opinions on issues ranging from microplastics in seafood to food miles and purchasing habits.

Pure Salmon said that while awareness levels around the environmental impact of sea farming were low, two-thirds of consumers in the same survey said they would be more likely to purchase fish that has been sustainably farmed. Sixty percent of those surveyed also said they would also pay more for fish with strong sustainable and environmental credentials.

The survey also found that when it comes to awareness of microplastics, U.K. consumers were ahead of the curve (55 percent awareness) compared to Americans (37 percent). Furthermore, 81 percent said it was either important or very important to understand where fish comes from when making purchasing decisions, and that 72 percent would be more likely to purchase fish if they knew it was produced close to their home, reducing food miles.

Pure Salmon was developed by investment firm 8F Asset Management Pte. Ltd.

Why climate change could mean more disease for marine aquaculture

April 15, 2019 — Extreme weather events and changing ocean conditions are creating unpredictable outcomes for aquaculture. One area where research is offering some insight into what to expect, though, is the increasing incidences of disease.

Anyone who was in France in the summer of 2018 can attest to the searing temperatures that swept the country. From north to south, the nation experienced the second hottest summer since records began. Whilst children played in lakes and the sea to cool off, the shellfish producers of Étang de Thau could only watch as their oysters and mussels perished at the hands of malaïgue – a period of sustained high temperatures and little wind.

The ocean has always been a highly dynamic environment, with its ever-changing conditions presenting challenges to aquaculturalists. However, thanks to human-induced climate change and continuing carbon emissions, events like malaïgue may become more regular occurrences, bringing with them new disease-related challenges.

As every aquaculturalist knows, temperature plays a major role in the growth and health of aquatic species. Certainly, higher temperatures are typically related to higher energetic requirements and demand for food. In an interesting twist, finfish can find their hunger suppressed when held at the upper end of their thermal tolerance for too long – even though their metabolic demands continue to rise. Malnourished fish make for unhealthy fish, which makes for a more stressed and susceptible animal.

Temperature doesn’t just impact farmed animals. As work from Dr Tommy Leung, a parasitologist at the University of New England in Australia has shown, temperature also appears to have a relationship with the severity and duration of disease outbreaks. “If you are in a more temperate region, you might have an outbreak where half of your stock die whereas in the tropics you have over 90 percent dying,” Leung explained. To compound the problem, outbreaks in those warmer tropical and near-tropical regions also happen over a much shorter period. “This means you could have less time to respond to any potential outbreak.”

Will plant-based fish food make aquaculture more sustainable?

April 12, 2019 — Replacing fish food with plants may not be as planet-friendly as it seems, according to a new study on the ecological impact of feeding soy and other land-grown crops to farmed seafood. These plant-based feeds are an alternative to, well, other sea creatures, which is what many species like shrimp and salmon eat in the wild. Published in the science journal Sustainability, the new study—which involved which involved an international and multidisciplinary team of experts—quantifies the effects that plant-based feeds have on land, water, and fertilizer use. The numbers that emerge challenge the prevailing notion that simply swapping fish-based fish food for plant-based fare can minimize the environmental footprint of aquaculture.

The interlocking limitations of fish-based feed, also known as fishmeal, have long confounded the aquaculture industry. For one, its ingredients—small, wild fish lower in the food chain, known as forage fish—are a finite resource. And as the global appetite for seafood continues to rise, so does the pressure to catch more. That means that fishmeal is becoming more costly and harder to source. As a result, producers have been trying to reduce their reliance in recent years.

“When shrimp farming became very popular 30 to 35 years ago, there was kind of a preference to grow as many shrimp as you can, as fast as you can, and get them out on the market,” says Cheryl Shew, a representative of specialty feed manufacturer Ziegler Bros. Inc. But like much of the industry, Ziegler began to experiment with soy as a partial substitute fishmeal in its feed products beginning in the early aughts, Shew tells me.

So why not just completely replace fishmeal with plants? It’s not as easy as it sounds—or as environmentally-sound, as it turns out.

Study questions sustainability of plant-based aquafeed

April 9, 2019 — A new study by researchers at the University of Stirling’s Institute of Aquaculture concludes that there is an urgent need for a paradigm shift in the definition of sustainable shrimp feed.

The global farmed shrimp industry has an estimated production volume around four million metric tons (MT), and has become one of the biggest consumers of fishmeal in the aquaculture sector. This has put pressure on aquafeed manufacturers to find suitable alternative ingredients that do not affect the health or growth rates of the shrimp.

However, substituting in plant-based alternatives to fishmeal may not be the panacea that ecological campaigners are counting on, according to the recently published research.

“The Sustainability Conundrum of Fishmeal Substitution by Plant Ingredients in Shrimp Feeds,” by Wesley Malcorps, models the effects of decreasing the inclusion of fishmeal in commercial diets.

“As demand for shrimp feed increases, feed manufacturers are shifting towards crop-based ingredients, in a move that is mainly driven by economic incentives. This is evidenced by looking at the relative price of fishmeal compared to common plant ingredients such as soy protein concentrate, cereal, and wheat gluten. Some consider the move to be a sustainable transition, as it reduces the dependency on a finite marine resource,” Malcorps told SeafoodSource. “However, a change in ingredients would shift resource demand from the oceans onto the land and could affect the nutritional value of shrimp.”

His team set out to model incremental fishmeal substitution by plant ingredients in feed for giant tiger prawns (Penaeus monodon) and whiteleg shrimp (Litopenaeus vannamei). The models were used to assess the consequent impact on marine and terrestrial resources such as fish, land, fresh water, nitrogen, and phosphorus.
