‘Extracting Value from the Right Amount of Fish’: Saving Seafood Looks at Aquaculture Efficiency

June 6, 2018 — WASHINGTON — Through new techniques and technologies, farming fish is becoming increasingly efficient, leading aquaculture experts tell Saving Seafood in a new video.

“With a whole range of factors – improved nutritional knowledge, better management techniques of feeding on the farm, and all of that – [the fish in–fish out] ratio has gone down,” says Andrew Jackson, Chairman of IFFO RS.

“For every 0.7 kilos of fish in, you get a kilo of fish out,” says Dan Lee, Standards Coordinator for the Global Aquaculture Alliance’s Best Aquaculture Practices Program. “So that’s becoming very favorable towards aquaculture productivity.”

In the case of salmon farming, nutritionists are using alternative ingredients, including plant proteins like soy, and mixing canola and other vegetable oils in with pure fish oil. This has helped lowered the percentage of marine ingredients in fish feed to about 25 percent of farmed salmon diets, and projections are that this will drop below 10 percent by 2025.

“They’ve figured out that the key to being successful and profitable and sustainable is not necessarily to catch more fish, it’s to extract as much value as possible out of the right amount of fish,” says Tim Fitzgerald, Director of the Environmental Defense Fund’s Impact Division.

These improvements have made farming fish one of the most sustainable forms of protein production, experts tell Saving Seafood.

“When you’re growing chickens or pigs or cattle, the transformation between the feed and the [farmed product] is much more inefficient than with fish,” says Manuel Barange, Director of Fisheries and Aquaculture at the UN Food and Agriculture Organization. “So if we have to feed any animal for us to eat, it makes sense to do that with fish. It’s more efficient.”

The video is the second in a series, Aquaculture Today, in which Saving Seafood interviews leading aquaculture experts on the latest advances in farmed fish, and its role in the world. Saving Seafood released a video yesterday on aquaculture’s role in feeding the world’s growing population.

In addition to Mr. Jackson, Mr. Lee, Mr. Fitzgerald, and Mr. Barange, the video also features Julien Stevens, Researcher at Kampachi Farms, and Neil Auchterlonie, Technical Director at IFFO.

Interviews for Aquaculture Today were conducted by Saving Seafood at the 2017 SeaWeb Seafood Summit in Seattle, Washington.

More Fish From Aquaculture Is Already Consumed In The World Than Caught

June 6, 2018 — “THE AQUACULTURE SECTOR ALREADY PRODUCES MORE THAN 50% OF THE FISH DESTINED FOR FOOD WORLDWIDE”

Las Palmas de Gran Canaria gathers in an international symposium organized by ISFNF and ECOAQUA the world’s leading experts in fish and crustacean nutrition.

As the world’s population continues to rise, threatening to surpass 7.5 billion people by 2020, the need to create high-quality aquatic products rich in omega-3s has soared to cover not only the food needs of people but also reduce the risk of suffering from many diseases in industrialized and non-industrialized countries.

Capture fishing and the collection of mollusks has served humans, in a traditional way, to obtain aquatic products that serve as the basis for their diet. However, marine resources are limited and, in the future, aquaculture will have a fundamental role to guarantee the production of aquatic species.

So says Marisol Izquierdo, director of the ECOAQUA Institute of the University of Las Palmas de Gran Canaria (ULPGC): “Aquaculture is probably the fastest growing food production sector today. The sector already produces more than 50% of the fish destined for food worldwide, adding up to more than 110 million metric tons, “he explains.

Fish, seafood, seaweed, cephalopods and other aquatic products are very important as a source of protein in human nutrition, and also provide phosphorus, calcium and, above all, omega-3. “There are many studies that show that a diet based on fish, and in particular omega-3, reduces the risk of suffering a multitude of diseases such as diabetes, pathologies of cardiovascular origin, various types of cancer, and also diseases of neurological origin such as Alzheimer’s and other types of dementia,” he stresses.

How Aquaculture is Feeding a Growing World: Saving Seafood Takes a Closer Look

June 5, 2018 — WASHINGTON — Global poverty and malnutrition are falling worldwide, and the availability of affordable, healthy protein is a key reason why. Aquaculture, as one of the world’s fastest growing sources of food production, has been an essential part of this development.

Saving Seafood is taking a closer look at the role that aquaculture plays as a source of food, nutrition, and employment for millions of people around the world in a new series, Aquaculture Today. We interview leading aquaculture experts on the latest breakthroughs and developments in farmed seafood, and the role it plays in the future of human health and the global food supply.

Worldwide, protein consumption has more than doubled in the past 50 years, going from 9 kg per person per year to nearly 20 kg per person per year. Fish, as a cheap and readily accessible food source, has made up a large share of global protein consumption. As the demand for affordable sources of protein grows along with the world’s population, these fish are increasingly being produced through aquaculture.

“Aquaculture has been the fastest [growing] food production industry in the world for the last four decades,” says Manuel Barange, Director of Fisheries and Aquaculture at the UN Food and Agriculture Organization. “We need to make sure that is maintained, perhaps not at the same growth, but that it is maintained because it provides not just nutrition, but actually livelihoods and economic opportunities in places where there are not many other opportunities for economic development.”

The importance of aquaculture to global seafood production is only expected to increase, with the production of farmed seafood expected to dwarf that of wild-caught seafood in the next 15 years.

“The projections are that we’ll reach 62 percent of food fish coming from aquaculture by around 2030,” says Dan Lee, Standards Coordinator for the Global Aquaculture Alliance’s Best Aquaculture Practices Program.

This growth presents an opportunity for fishing communities, which have a chance to diversify to meet the needs of the global seafood market.

“One thing that I would really like to see the industry support [NOAA] stepping up with is dealing with this sort of issue, trying to help these communities start to either diversify their fisheries or thinking more about how they can move into aquaculture,” says Richard Merrick, former Chief Scientist at NOAA Fisheries.

Aquaculture Today comes from interviews conducted by Saving Seafood at the 2017 SeaWeb Seafood Summit in Seattle, Washington.

Marine heatwaves are getting hotter, lasting longer and doing more damage

June 1, 2018 — On land, heatwaves can be deadly for humans and wildlife and can devastate crops and forests.

Unusually warm periods can also occur in the ocean. These can last for weeks or months, killing off kelp forests and corals, and producing other significant impacts on marine ecosystems, fishing and aquaculture industries.

Yet until recently, the formation, distribution and frequency of marine heatwaves had received little research attention.

Long-term change

Climate change is warming ocean waters and causing shifts in the distribution and abundance of seaweeds, corals, fish and other marine species. For example, tropical fish species are now commonly found in Sydney Harbour.

But these changes in ocean temperatures are not steady or even, and scientists have lacked the tools to define, synthesize and understand the global patterns of marine heatwaves and their biological impacts.

At a meeting in early 2015, we convened a group of scientists with expertise in atmospheric climatology, oceanography and ecology to form a marine heatwaves working group to develop a definition for the phenomenon: A prolonged period of unusually warm water at a particular location for that time of the year. Importantly, marine heatwaves can occur at any time of the year, summer or winter.

Washington state finds virus in Cooke Atlantic salmon, plans expanded testing

May 21, 2018 — After identifying an exotic virus in fish raised by Cooke Aquaculture, Washington state is planning to test at other sites where the pathogen from Atlantic salmon may have been spread.

The state this week blocked restocking of one of Cooke’s net pens after fish at the company’s rearing facility in Thurston County tested positive for the virus.

Ken Warheit, fish-health manager for the Washington Department of Fish & Wildlife (WDFW), will, as soon as possible, test Cooke’s settling ponds at its incubator in Rochester, Thurston County, as well as Scatter Creek and its confluence with the Chehalis River for the presence of the virus found in the Atlantic salmon smolts raised by Cooke.

The pathogen could have contaminated surrounding water, raising a concern for its potential to affect native Pacific salmon, Warheit said.

Cooke’s request for a permit to transfer the smolts to open-water net pens for growing to harvest size was denied for the same reason, Warheit said.

Why should you care about fisheries? They can help feed the world.

May 16, 2018 — Food security is a hot button topic for today’s world leaders, and rightly so as the population swells to 10 billion people by the middle of the century. Feeding that many people is a huge challenge – creating an urgent call to action for resources to be managed more sustainably and equitably – and wild seafood plays a big role.

Typically, these discussions focus on land-based agriculture, including the production of grains, seeds, crops and livestock that, while subject to droughts, diseases and shortages, are the main source of world food consumption as measured by total calories. However, food sources from our oceans, lakes and rivers also play a large part in feeding the world, and deserve their place in the discussion.

That’s why we’re excited to share a new report from Duke University and EDF* examining how wild capture fisheries fit into this complex discussion and summarizing what we know about the potential role of fish and other aquatic resources, like shellfish and crustaceans, to help feed an increasingly hungry world. After all, three billion people rely on seafood as a primary source of protein, and this number will only continue to grow.

How the world’s second largest indoor salmon farm could take shape in Maine

May 11, 2018 — BELFAST, Maine — You might have to squint through the trees to spot the world’s second largest salmon farm in Belfast, according to computer renderings unveiled Wednesday.

Nordic Aquafarms, a Norwegian aquaculture firm, says its due diligence, the process used to determine whether the project would be feasible, is about 90 percent complete, and is ready to start applying for permits.

Nordic hosted its latest information session at the Hutchinson Center in Belfast on Wednesday night.

In its first phase, Nordic would build a 300,000-square-foot building on a 40-acre plot near the Northport town line. The building will be about 10-15 feet shorter than surrounding trees, largely hiding it from view, according to Nordic’s CEO Erik Heim.

Chinese fish farm tests deep-sea waters with ‘world’s biggest’ salmon cage

May 8, 2018 — A Chinese fisheries company will soon launch a massive deep-sea salmon farming facility in the eastern province of Shandong to help meet the country’s growing appetite for seafood.

Shandong Wanzefeng Fishery, the operator, said a fully submersible net cage called Deep Blue No 1, the world’s biggest, was delivered to the shipyard of state-owned Wuchang Shipbuilding Industry on Friday, state-run Xinhua reported.

The 35-metre-high cage will be deployed in the Yellow Sea about 130 nautical miles east of Rizhao where the cold water is believed to be a suitable habitat for the fish.

Wang Yu, head of the Hubei Marine Engineering Equipment Research Institute, which designed the system, said the cage had a volume of 50,000 cubic metres and could generate a harvest of about 1,500 tonnes of salmon per season.

These machines from Japan could put scallop farming in Maine on the map

April 30, 2018 — A project in Maine, boosted by a new grant, would establish the first semi-automated commercial scallop aquaculture operations outside Japan.

The $300,000 grant to CEI, a Brunswick business development organization, from the Foundation for Food and Agricultural Research of Washington, D.C., will help fund efforts to test the economic viability of cultivating scallops on ropes at aquaculture sites in Maine’s coastal waters.

As part of that effort, Bangs Island Mussel in Portland and Pine Point Oyster in Scarborough are testing out machinery made in Japan that should help automate much of the labor-intensive process of attaching and growing scallops on ropes vertically suspended in the water.

Testing and possibly modifying the machinery is just one of multiple angles in trying to develop a market for farmed scallops from Maine, according to Hugh Cowperthwaite of Brunswick-based Coastal Enterprises Inc.

CEI, which is administering the three-year grant, also plans to conduct market research to gauge the potential demand for scallops grown in such a manner, and to write a “how-to” manual for interested aquaculturists, Cowperthwaite added. Rope-grown scallops likely would have to serve a specialty market to be economically viable, he said, because they cannot match the high volume and relatively low production expense of the Northeast’s wild scallop fishery.
