Saving Seafood

The Beyond Meat of Fish Is Coming

June 13, 2019 — Salmon has become the guinea pig of the seas when it comes to using technology to supplement falling fish populations. Now it’s moved onto land—and into the laboratory.

The fatty orange fish was the second-most-consumed seafood in the U.S. in 2017, after shrimp, and per capita consumption increased 11 percent, to 2.41 pounds per person, from the prior year, according to the National Fisheries Institute, an industry group. Globally, demand for salmon has skyrocketed, along with that for all fish, fueling overfishing and threatening supply.

Industrial-scale salmon farming, once seen as a solution, has its own problems. Massive stocks of smaller fish are depleted to feed farmed salmon, and parasites flourish in salmon pens where farmers use pesticides, contributing to pollution and ecosystem destruction. Sea lice have infested farms in Norway and Scotland in recent years, and a deadly algae bloom killed salmon in Chile, a top farmed-salmon producer. Farmed fish sometimes escape, too, contaminating nearby wild salmon.

Canadian Farmed Salmon Will Face Additional Tests for Viruses

June 10, 2019 — SEAFOOD NEWS — Fisheries and Oceans Canada will test for two foreign strains of piscine orthoreovirus in young Atlantic salmon before they are transferred to ocean-based salmon farms after being told by the Federal Court to tighten its policy.

Salmon farms will also be required to test salmon in net-pen farms for jaundice and heart and skeletal muscle inflammation, which some scientists believe is associated with a native strain of piscine orthoreovirus, also known as PRV.

“These are two key measures that reflect precaution where there is some debate about the science,” said Fisheries Minister Jonathan Wilkinson.

The Icelandic strain of PRV was found in a Washington state hatchery last year, leading to the destruction of 800,000 smolts. The Norwegian strain has caused harm to farmed and wild Atlantic salmon in Norway, leading to significant production losses.

“We are going to require testing (in hatcheries) for both of those strains because we are concerned about them,” said Wilkinson.

Earlier this year, a federal scientific advisory panel found that the native strain of PRV is widely distributed in B.C.’s coastal waters, but poses a minimal threat to Fraser River sockeye. B.C. PRV is commonly found in farmed Atlantic salmon and wild Chinook salmon, but in laboratory testing its presence is not predictive of disease, they said.

Nonetheless, testing for heart and skeletal muscle inflammation and jaundice will address concerns raised by independent biologist Alexandra Morton that the native strain of PRV is affecting farmed salmon, Wilkinson said.

The Namgis First Nation went to court last year seeking an injunction to prevent salmon from being transferred to farms in their traditional territory without having been tested for PRV. Ecojustice – acting for Morton – sued the federal government for an order to test for the virus.

In February, the Federal Court gave Ottawa four months to come up with a testing regimen, ruling that failure to test for PRV did not comply with the precautionary principle.

“This is absolutely amazing and wonderful news,” said Morton.

“While I am waiting to see who will conduct the tests and what the protocol will be when they find the virus, I recognize this as a bold and important step that no other minister of Fisheries and Oceans has taken.”

These interim measures will be in place while the federal government seeks public input on a pair of policy proposals aimed at reducing the risks of salmon farming.

“Salmon farmers already test for several known pathogens and these new tests will become part of that process,” said B.C. Salmon Farmers Association spokesman Shawn Hall.

“It’s our understanding that the native strain of PRV is in the water naturally and that is it benign.”

Failing to test for B.C. PRV is a missed opportunity to fill in gaps in the science about that strain, said David Suzuki Foundation science adviser John Werring.

“It is heartening to hear that the minister for Fisheries and Oceans Canada acknowledges that there is a great deal of uncertainty concerning PRV and the potential impacts this virus may have on both wild and farmed fish,” Werring said.

The Fisheries Department has also struck three working groups comprised of government scientists, First Nations, environmental groups and the farm industry to provide input on permanent changes to the department’s risk-management policy, specifically the switch to area-based management of aquaculture, land-and oceanbased farm design and fish health.

Results of a study on new and emerging aquaculture technologies – including ocean-based closed-containment systems and land-based farms – are due later this month.

Patchwork of policies holding back US aquaculture industry growth

June 7, 2019 — The 47th United States-Japan Natural Resources Scientific Symposium “Marine Aquaculture in a Changing Environment” will be held November 12 to 15, 2019, in Okinawa, Japan. It will be the last year for the three-year theme, “Marine Aquaculture in a Changing Environment.”

The symposium is part of a regular collaboration between NOAA Fisheries and the Japanese Fisheries Research and Education Agency, organized through the U.S.-Japan Natural Resources (UJNR) Aquaculture Panel. The panel is an annual meeting framework that allows scientists to share research results, new technology, and approaches to sustainable seafood farming. Last year’s meeting took place in Mystic, Connecticut, U.S.A.

Mike Rust, a NOAA Fisheries scientist and the U.S. chair of the UJNR Aquaculture Panel, told SeafoodSource the exchanges represented an important path to improving the state of U.S. domestic aquaculture.

“The learning opportunities are tremendous on a number of fronts. The United States is behind in both the scale of marine aquaculture and the science and technology effort to support a sustainable industry. This partnership gives U.S. researchers a chance to understand where Japan is going in aquaculture and learn from Japan’s experience,” Rust said. “The low-hanging fruit in some ways is to look around the world to see where other people are on the technical side.”

New aquaculture regulations for Scotland; Salmon farms could get bigger

June 7, 2019 — A new, evidence-based regulatory framework has been introduced for Scotland’s finfish aquaculture sector by the Scottish Environment Protection Agency (SEPA).

Launched following 22 months of work by SEPA, the framework implements proposals announced in November 2018, which were subject to a country-wide consultation. According to the public body, it takes advantage of more accurate computer-modeling approaches that will improve understanding of the risks to the local environment and allow assessment of the larger-scale impacts including interactions with other farms.

SEPA acknowledged that the science about fish-farming is “very complex” and said that the new approach would bring the sector up to date with the modeling practices used for other industrial sectors where there is a longer history of operation and analysis.

SEPA Chief Executive Terry A’Hearn said the new framework was an “important milestone” for the sector.

“It makes powerfully clear our aspirations and requirement that the industry reach and maintain full compliance with Scotland’s environmental protection laws, where SEPA will help those investing in innovation and moving beyond compliance,” he said.

Alaska’s fledgling mariculture industry expands its reach; former Dunleavy staffer named to fish board

June 6, 2019 — More Alaskans are turning to seaweed farming as the state’s fledgling mariculture industry expands to more regions. Shellfish growers also are finding that an oyster/aquatic plant combo boosts their bottom line.

Sixteen applications were filed for new or expanding aquatic farms from January through April, of which 56% were for growing various kelp, 31% for a combination of Pacific oysters and kelp, and 13% for oysters only.

While 2019 saw the same number of applications as 2018, the underwater acreage increased considerably, said Cynthia Pring-Ham, aquatic farming coordinator at the Alaska Department of Fish and Game, which issues the farm permits.

“There were about 616 acres that were applied for in 2019 compared to 462 acres in 2018. That’s about a 33% increase,” she said, adding that Fish and Game partners with the state Department of Natural Resources, which leases the tidal and submerged lands where aquatic farming takes place.

Texas passes law allowing oyster aquaculture

June 5, 2019 — Texas Governor Greg Abbott recently signed a bill into law establishing a new regulatory framework allowing for oyster aquaculture on the state’s Gulf Coast.

Before passage of House Bill 1300, Texas was the only coastal state in the U.S. that didn’t allow oyster mariculture off its coasts. The new law allows oysters to be raised for their pearls, as well as their shells and meat.

Set to go into effect, the new law requires the Texas Parks and Wildlife Commission to adopt rules that would establish a program to regulate the process of growing oysters. Abbott signed the bill into law last month, the last day of the 2019 session of the Texas Legislature.

Finfish Farming: Envisioning Aquaculture in San Diego

May 31, 2019 — About three miles from shore, a fishing boat tethers to an immense circular ring bobbing on the surface.

The fish pen sways with the current but is moored to the ocean floor nearly three hundred feet below. Inside the carefully structured net, hundreds of Yellowtail flash as they move effortlessly up and down the water column.

The pen casts a shadow and as with pads of broken kelp, wild fish cluster near, claiming shelter in the open sea while others shuttle beneath the pen looking for food.

This is the vision that Don Kent, CEO of Hubbs Seaworld Research Institute (HSWRI) shares with scientists, the Port of San Diego and the National Oceanic and Atmospheric Administration (NOAA). While shellfish farming has been successful locally for years, ocean finfish pens would be a first for the region.

Today Americans import 90% of the seafood they consume. Fish farming could reduce that percentage and harvesting close to home would lower the carbon footprint.

How it would benefit local markets and fishermen is another question.

Eating fish is a healthy, environmentally positive option and aquaculture can make the benefits more accessible and affordable. The scientists at Sustainable Fisheries point out, “The more seafood that is eaten in place of cow, the better, since [industrial] bovine farming is the largest driver of rainforest and biodiversity loss on the planet.”

5 Innovations In Aquaculture Worth Catching On To Now

May 30, 2019 — Aquaculture is one of the fastest growing forms of food production in the world and the fastest growing sector in the livestock industry. In a $140 billion market, startups in seafood and aquaculture technology raised $193 million in 2016, which marked a 271% increase from the two years prior combined. The latest group of innovations in agtech could very well come from the water, as something we could call “aquatech.”

Yet there are many areas in this industry that are in dire need of innovation. Today, I will focus on my top 5: disease prevention, vaccine delivery, fish meal replacement, sustainability solutions (including closed-loop farming) and supply chain management.

Tremendous opportunity exists right now for those interested in investing in the solutions to these issues. Let’s take a look at the five key areas mentioned, and how several forward-thinking companies are meeting them head on.

Disease prevention is a critical aspect of aquaculture. Changing ocean temperatures and water quality make animals and plants more stressed and susceptible to disease, yet innovation is lacking in prevention compared to land-based agriculture. Terrestrial food animal farmers can easily deploy dozens of vaccines and preventive solutions, while aquaculture has less choice and significant delivery challenges (more on this below). Vaccines are still administered by hand, and there simply aren’t good preventive measures for many infestations.

It’s Time to Be Honest about Seafood

May 28, 2019 — Demand for seafood is increasing across the globe, and the United States is no exception. Aquaculture, or aquatic farming, is increasingly meeting this demand and now supplies just over 50 percent of all seafood globally. In fact, it has been one of the world’s fastest growing food sectors for years.

The U.S. is the largest importer of seafood in the world, and some of Americans’ favorites—including shrimp, salmon and tilapia—are predominantly farmed these days. Yet, we contribute less than 1 percent of the world’s total aquaculture production. This means we rely heavily on other countries to satisfy our appetites for seafood.

If the U.S. does not increase its domestic production of farmed shellfish, seaweed and finfish, the divergence between what we consume and what we contribute to the global seafood market will continue to widen. This gap may make it harder for our seafood diets to be sustainable. It also means the U.S. won’t have a hand in shaping the standards or economies that contribute to the seafood sector as a whole in the future.

A brand-new bill that proposes a moratorium on commercial permits for marine finfish aquaculture facilities in U.S. waters could serve to widen this gap, and it represents another divergence: between public wariness about domestic aquaculture operations and the science showing aquaculture’s potential for sustainable growth.

While wild-caught fisheries have hit “peak fish” domestically and globally, with limited potential for additional sustainable growth, there is mounting scientific evidence that the U.S. could dramatically increase domestic aquaculture production and do so sustainably, as we did with our fisheriesbefore they peaked. And this growth does not have to come at the cost of our wild-caught fisheries or other priorities for our oceans, especially under careful management and planning.
