NaturalShrimp, a publicly traded agro-tech company, has started testing the patent-pending technology in a 65,000-gallon tank at its pilot production farm near San Antonio, Texas.
The company says the technology is “potentially disruptive to the entire shrimp farming industry.” “NaturalShrimp’s patent pending Vibrio Suppression Technology effectively eliminates water-borne bacteria and other harmful organisms and keeps ammonia at safe concentration levels, thus eliminating one of the historically most difficult problems in shrimp aquaculture,” it said on its website.
Under the plan, a former shipyard in the town of Marystown, Newfoundland, will be converted into a service facility. Marbase Marystown Inc, a partnership between a Newfoundland-based private equity company and a Norwegian firm are behind the plan, reported the Southern Gazette.
“Marbase will bring together key suppliers to enhance the industry’s supply chain efficiency, enable access to key resources, improve advanced technology transfer, and move Canada’s aquaculture production towards a more modern, sustainable and efficient future,” the publication reported, citing a leaked document.
However, the plan will only move forward if the province of Newfoundland will approve the Grieg NL project, the report said.
Dr Bill Walton of Auburn University will focus his study on oysters raised using off-bottom farming technique. The technique involves raising the baskets of oysters from the water once a week to air-dry them to prevent barnacles and other invasive species from attaching themselves to the oysters. Walton will find out whether an oyster farm’s geographic location, handling practices, and choice of equipment affect Vibrio levels in these oysters.
“Through his project, Walton should generate valuable data for Gulf Coast oyster farmers, who focus on producing exceptional oysters for high-end markets, such as upscale restaurants that offer the farmed bivalve mollusks on the half shell,” Auburn University said in a press release.
The USDA has given more than $450,000 for the three-year research project.
The interactive workshop will cover a wide range of topics, from the basics of indoor marine shrimp farming to the latest in technological innovations, research, regulations, post-larvae supply to marketing. It will feature a series of presentations and round table discussions with experts in the field and policymakers who help shape the future of shrimp farming in the US and globally.

“While the importance of salmon farming is well understood in the communities where our members operate, that is not the case in urban centers and there is no question we have work to do on that front. I look forward to bringing forward the story of just how important and progressive this industry is. My first priority is to gain the public’s trust,” said Fraser, whose appointment was announced today.
Fraser was BC’s deputy minister responsible for Government Communications and Public Engagement until last year. “I was drawn to this role by the opportunity to become an advocate for this important but misunderstood industry at a critical time,” Fraser said.
“I was struck with just how deeply our province’s salmon farmers understand that wild salmon come first and that they play a critical role in protecting wild fish populations. They understand they must, and do, operate responsibly by using the most innovative green techniques and acting on independent science. They also understand how important it is that they are giving consumers a local and healthy alternative to eating wild salmon when making their meal choices.”
The association’s previous executive director, Jeremy Dunn, is now Director of Community Relations & Public Affairs at Marine Harvest Canada.
Agrosuper has a salmon unit, Los Fiordos, which sells its produce under the Super Salmon brand. The company's main markets include the United States, Mexico, Italy, Japan, China and Brazil, but most exports to these countries are broiler products. The $850-million deal with AquaChile will make it one of the world’s biggest players in salmon aquaculture.
AquaChile markets its produce under the Verlasso brand, “named the first and only ocean-raised farmed Atlantic salmon to receive the ‘Good Alternative’ buy ranking from the Monterey Bay Aquarium’s Seafood Watch program,” according to the company.
The producer of the AquAdvantage genetically modified salmon attributed the losses to pre-production costs at its Indiana farm and R&D activities at the Rollo Bay hatchery in Prince Edward Island, Canada.
In an update on the Indiana farm that the company acquired last year, AquaBounty said it has stocked it with traditional Atlantic salmon eggs and has commenced grow-out activities while waiting for approval from the US Food and Drug Administration (FDA) to import AquAdvantage Salmon eggs.
The company is prevented from importing its AquAdvantage Salmon eggs from Canada due to the existence of an "Import Alert" pending the FDA's issuance of final labelling guidance for the product, it said in an earlier announcement.
“The Company has indicated that it is fully prepared to comply with labelling requirements for its product in order for this process to conclude in the near term.”
It expects the import alert on AquAdvantage Salmon to be lifted in the second half of the year.
The farmed salmon will be fed a new feed solution that contains oil extracted from camelina crop that was genetically modified make health-beneficial Omega-3 fish oils.
Current industry practice involves feeding farmed fish with feed containing marine fish oil, sourced from the sea, and vegetable oil. Supply from the wild fisheries is, however, unsustainable.
The new study will determine if Omega-3 fish oils coming from the GM camelina plant will be a worthwhile substitute. The researchers will compare the performance of the fish fed the new feed solution in terms of weight and growth of the fish, with farmed salmon fed a standard diet. They will also compare their tissue and molecular samples.
Plant scientist Professor Johnathan Napier, who developed the GM plants at Rothamsted Research, and fish nutritionist Professor Douglas Tocher, of Stirling’s Institute of Aquaculture, will jointly lead the study. Dr Monica Betancor, a Research Fellow at Stirling, will also play a crucial role by checking on the health of the fish and collecting data.
The potential for using Camelina sativa as a substitute for fish oils and fishmeal in aquaculture feeds has been explored in recent years. In April 2017, the Canadian Food Inspection Agency approved mechanically extracted camelina oil for use as a feed ingredient for farmed salmon and trout.
Entomics Biosystems Ltd of Cambridgeshire, England says merely drying insects (in this case BSF) and milling them into powder misses many of their potential nutritional, health and wellbeing benefits. A proprietary bioprocessing technique that Entomics developed, which it calls "metamorphosis," boosts the nutritional and functional benefits of such insect-derived feeds.
"There are several benefits to this process," explains Miha Pipan, Chief Scientific Officer and company co-founder, in an article published in the University of Cambridge website. Benefits range "from affecting the gut's microbiome and trying to preserve a healthier bacterial community there, to training immune systems to make livestock more resistant to disease challenges and at the same time reduce the need for veterinary medicines, antibiotics and vaccines.”
“We are currently focusing our efforts on developing functional insect meals for Atlantic salmon (Salmo salar), in particular in our meals' ability to stimulate salmonid immune system strengthening and overall wellbeing,” said the Entomics team, whose members are University of Cambridge graduates.
They are currently working with partners including the University of Stirling to validate and test their products in the field.
Entomics CEO and co-founder Matt McLaren noted how the world is looking for more sustainable sources of feed. “I think increasingly there's a recognition that it's not just about basic nutrition, but it's about overall health," he says.
"We're trying to take a promising, sustainable ingredient of the future – these insect-derived feeds – and trying to add a bit of biotechnology or science focus to it, to really enhance what the effect is in the end application and reduce reliance on traditional antibiotics and veterinary medicines."
There are several efforts currently looking into developing fish feed out of BSF because fish feed derived from fishmeal is deemed unsustainable.

Current managing director, Vincent Erenst, is leaving the company in October for a new opportunity, the company announced.
The salmon producer thanked Erenst “for his dedicated and successful work” in the company’s Western Canadian Operations.
“Vincent has been the Managing Director of Marine Harvest Canada since 2007, overseeing the build out of a sustainable business unit for Marine Harvest. He has also taken leadership roles within the industry in British Columbia and Canada, serving as the Chair of the BC Salmon Farmers Association for many years. Marine Harvest expresses its sincere thanks to Vincent for the very significant contribution he has made to the development of Marine Harvest Canada. The company wishes him all the best and continued success in his new working life,” said MHC.
The Canadian company says XpertSea’s platform uses artificial intelligence and computer vision to count and size early-stage aquatic organisms such as shrimp larvae and live feed.
The XpertCount is a smart IoT (internet of things) device that connects to a portal where customers can access data and analytics from any device, anywhere.
As of 2017, XpertSea’s customers in 48 countries have counted more than 17 billion organisms and uploaded over 100,000 counting and sizing sessions to the data portal, said the company. It recently found investors in Obvious Ventures, Aqua-Spark, and Real Ventures, which together raised C$10 million in Series A financing.
"This investment will help XpertSea take the guesswork out of aquaculture inventory management, which will drive profits for aquaculture producers and deliver positive environmental returns for our planet,” said Valerie Robitaille, CEO and co-founder of XpertSea.
“Precision aquaculture technology is the key to bringing transparency to transactions and standardizing practices across the industry, which benefits everyone along the aquaculture food chain,” she added.
Global Aquaculture Alliance (GAA) President George Chamberlain believes the future of shrimp aquaculture lies primarily in breeding innovations.
“I want to make the case with you that there’s nothing we can do in any aspect of aquaculture that has the cumulative benefit year after year as breeding. I would say it is the primary driver of improvement,” he told the audience at Aquavision 2018 in Norway.
Shrimp diseases such as early mortality syndrome and Enterocytozoon hepatopenaei (EHP) “slowed down the industry’s growth to a crawl,” he said, and impact prices. “Shrimp prices are very volatile due to high prices when there’s a disease outbreak and a shortage in supply, and a plunge in prices when there’s a recovery.”
Chamberlain said breeding innovations would be key to addressing the industry’s challenges.
“In breeding it’s reasonable to expect a 10-percent improvement every generation. If you’re a feed supplier for example, you would be lucky to get a 2-percent improvement each year and can’t probably do it every year. I would say that’s true in every aspect of the value chain, such as processing, hatchery etc. So breeding is super important.”
Breeding today is focused on “agronomic traits,” characteristics that farmers want, he added. These include traits for growth, resistance to multiple pathogens, reproductive performance and soy tolerance, to name a few. “In the case of shrimp, vaccines don’t work per se since they don’t have an antigen antibody system, so genetic resistance is an incredible tool. The Ecuadorians have certainly demonstrated that,” Chamberlain said.
“Although much talked about, the upcoming legislative changes around recreational cannabis don’t change current workplace policies. We are planning some outreach to remind staff of this, but impairment in the workplace is a safety issue and is governed by WorkSafe BC (a provincial government agency responsible for workplace safety.) At Creative Salmon, recreational cannabis use/impairment in the workplace is forbidden. Post legalization, that will still be the case,” Lisa Stewart, human resources manager of Tofino-based Creative Salmon, tells ANA.
Policies are also in place regarding the use of controlled substances at Marine Harvest Canada (MHC), says Jeremy Dunn, director of community relations and public affairs. “Recreational cannabis will be added to the list of controlled substances in BC (along with alcohol) and our policies will be updated to include where appropriate,” says Dunn.
In the shellfish industry, “anecdotal evidence suggests shellfish farmers will not allow pot in the workplace or during work hours any more than alcohol is permitted,” says Darlene Winterburn, executive director of the BC Shellfish Growers Association. WorksafeBC regulations set the standard for industry rules that pertain to employee impairment by alcohol, drugs and other substances. The safety of our workers is paramount.”
But aquaculture diver Kelly N. Korol is concerned. The director of Training/Owner of DIVESAFE International says that a lot of dive companies and dive supervisors are worried about rules and how this will affect the workplace.
“It will be available as readily as alcohol,” says Korol, but unlike alcohol intoxication, which gives off clues such as smell and behaviors, and where tests are available to determine the level of intoxication, pot intoxication does not, he wrote in DIVESAFE newsletter, which the company shared with ANA.
“Who can say if glassy eyes are a result of pot or simply allergies?,” Korol asks. He says it is not about the diver’s ability to dive, but rather it is about responsibility to co-workers because it could put others in harm’s way. “The bottom line is that responsibility must fall on the diver. No matter how together one feels after smoking a big fatty (a marijuana cigarette), they should not be diving commercially.”
The provincial government says recreational marijuana will be legal beginning October 17, 2018. “We’re now focused on developing the regulations and supporting policies for the implementation of our provincial regulatory regime. We are also working on provincial public awareness and education campaigns, to ensure British Columbians have the information they need regarding legalization and our provincial regulations when they come into force,” said Mike Farnworth, Minister of Public Safety and Solicitor General, in announcing the federal Cannabis Act.
Green Seafoods did grow-out trials in 2000 but the biggest problem was securing the right feed to increase the roe (gonads) to a marketable size. Operations manager Mark Sheppard says the sea urchins they were raising ended up tasting like what they had just eaten, for instance, kelp or fish protein.
With access to feed developed by Norway-based Urchinomics and Nofima, he hopes this second round of sea urchin grow-out trials will yield better results. The feed is special in that it holds its form in water for between seven to 14 days without dissolving, a quality important for urchins because they take a long time to eat.
“We know that it works in the lab. We are going to do some full-blown commercial trials this fall,” he says.
“The latest list of $200 billion of products to be subject to tariffs against China doubles down on a reckless strategy that will boomerang back to harm US families and workers,” said the National Retail Federation (NRF).
“The threat to the US economy is less about a question of ‘if’ and more about ‘when’ and ‘how bad.’ Tariffs on such a broad scope of products make it inconceivable that American consumers will dodge this tax increase as prices of everyday products will be forced to rise. And the retaliation that will follow will destroy thousands of US jobs and hurt farmers, local businesses and entire communities,” the association said.
The US decision to impose higher tariffs stems from China’s “unfair” and “harmful” industrial practices that restrict trade between the two countries. Under the plan, the US will levy 10-percent tariffs on a lst of imports from China. The list includes a wide range of seafood that goes to China for reprocessing and then imported back into the US for the local market.
Tariffs on seafood
Increasing tariffs has its share of supporters, however. Some US shrimp suppliers believe the tax will help curb oversupply. Some tilapia producers believe the tariffs will make trade with their Chinese counterparts more equitable.
“It’s about time we did something to level the playing field as it were, through the shrimp and tilapia, two of the major seafood coming out from China. Cannery is a government-subsidized industry in China. They keep the prices low to keep competition out,” commented Bill Martin, president and CEO of Virginia-based Blue Ridge Aquaculture.
Martin noted that as a live-tilapia supplier, the tariffs issue has no impact on Blue Ridge Aquaculture, known as the world’s largest producer of indoor-raised tilapia. “But we hope down the line when we start to process fish this will give us a level playing field,” he told Aquaculture North America (ANA).
He is confident the tariffs will not have much of an impact on US tilapia prices. “I would be surprised it if it will be much of an increase. Central America suppliers and Brazil are moving into tilapia in a big way, Chile is moving into it in a big way. I expect that void to be filled very quickly [by them].”
The planned tariffs will be finalized in late August after the public-comment period. Martin is hopeful the trade spat will be short term and a deal will be struck before it will have any impact.
NRF is meanwhile urging the Trump administration to strike a deal with China.
“The administration has been pursuing tariffs now for months and we still don’t know what the endgame is. Now is the time to get back to the negotiating table with China while working through a global coalition that shares our concerns. The way things are shaping up, it may be too late, but we hope the administration changes course before we lose the momentum from tax and regulatory reform and return to an era of high prices, job loss and negative growth in our economy,” the group warned.
A University of Pittsburgh study led by Dr Carla Ng, assistant professor of civil and environmental engineering at the Swanson School of Engineering, tracked the presence of PBDEs in farmed salmon.
Despite having been banned in the United States and much of Europe in 2004 because of environmental and public health concerns, PBDEs continue to be released into the environment from products manufactured before the ban of PBDEs, the study says.
“They enter the air and water and can accumulate in prey fish which are then used in the manufacture of feed ingredients,” Ng explains to Aquaculture North America (ANA).
If the exact location of the catch used as feed ingredients is unknown and/or the materials have not been tested for the presence of the pollutants, it can be difficult to tell ahead of time which animal-derived feed ingredients contain PBDEs, Ng acknowledges. But the study noted that PBDEs are particularly dense in areas such as China, Thailand, and Vietnam, countries that process a lot of electronic waste and lack rigorous regulation of their recycling industries.
Dr Neil Auchterlonie, Technical Director at IFFO, the marine ingredients organization, recognized the presence of these chemicals in “extremely small (amounts) and in generally declining concentrations.”
In deciding whether this means we should stop eating farmed salmon, Auchterlonie tells ANA: “One of the facets of the continual development of analytical technology is the identification of some of these compounds in ever-smaller concentrations. Those results are often so small that they are confusing when it comes to the interpretation of risk. That risk is important to bear in mind when taken into account with the noted benefits of consuming seafood.”
He adds that it is also important to recognize that these materials are found throughout the environment, not just in seafood. In fact, synthetic flame-retardants are everywhere. “As well as being present in the aquatic environment, PBDEs are present in the atmosphere, and in dust, which can also be sources of exposure,” he says.
Still, the risk to human health appears to be minute. A report from the Norwegian Scientific Committee for Food Safety, which covered an extensive overview of contaminants including PBDEs, concluded that the risk of adverse health effects due to PBDEs is low.
Animal nutrition specialists and fish feed manufacturers contacted for comment did not respond by our deadline.
The Norwegian salmon producer harvested 78,5000 tonnes of gutted weight equivalent, which is lower than the total harvest volume of 82,000 tonnes predicted.
The company will release its complete Q2 2018 report on 22 August.
Global fish production peaked at about 171 million tonnes in 2016, of which aquaculture accounts for 53 percent (excludes non-food uses) or 80 million tonnes, with first-sale value of $231.6 billion.
With 5.8 percent annual growth rate since 2010, aquaculture continues to grow faster than other major food production sectors. In 2016, aquaculture production increased by 4 million tonnes over the previous year.
In contrast, capture fisheries production was at 90.91 million tonnes, relatively unchanged since the late 1980s. This shows aquaculture has been responsible for the continuing impressive growth in the supply of fish for human consumption, says the report.
Fish consumption is also at an all-time high at 20.3 kg per capita in 2016 versus just under 10 kg per capita in the 1960s. The report attributes this too to increased production via aquaculture.
By 2030 the world will eat 20 percent more fish (or 30 million tonnes live equivalent) than in 2016. Aquaculture production that year is projected to reach 109 million tonnes, a growth of 37 percent over 2016.
The projected increase in global fish consumption raises concerns over sustainability of fish farming and fisheries, however. The United Nations warns future growth will require continued progress in making aquaculture and fisheries more sustainable. For instance, the sectors can improve efforts in reducing the amount of fish being discarded at sea or thrown out post-capture by using discards and trimmings to produce fishmeal, it said.
