RAS to disrupt the salmon sector within the next decade, says Rabobank

October 18, 2019 — The tide is turning for recirculating aquaculture systems (RAS) and this emerging technology has the potential to change the face of aquaculture over the next decade, claims a new report from Rabobank.

Analysis in the “Aquaculture 2.0: RAS Is Driving Change” report, compiled by RaboResearch Food & Agribusiness, states that while the “RAS concept is still under development and the future holds uncertainties,” the number of proposed projects to farm seafood species using this technology is increasing day by day, with the majority of ventures focused on salmon farming.

Why a Hollywood producer bought a fish farm … or eight

October 17, 2019 — Fishing for wild salmon in British Columbia is what inspired famed Hollywood television writer and producer David E. Kelley to enter the aquaculture industry six years ago.

At the Aquarium of the Pacific in Long Beach, California on 16 October, Kelley – who is the producer of TV shows such “Big Little Lies” and “Ally McBeal” – explained how he became founder and chairman of Riverence, a sustainable steelhead trout farming operation in Filer, Idaho, as well as a salmon and trout egg producer in Olympia, Washington.

RWU Law, URI among institutions to share $1.2M grant to help local aquaculture

October 16, 2019 — The Marine Affairs Institute at Roger Williams University School of Law and Rhode Island Sea Grant Legal Program, housed at the law school, has been included in a $1.2 million grant to promote the growth of southern New England shellfish aquaculture, as part of a National Sea Grant initiative.

The University of Rhode Island will also be a partner in the program, which will aim to promote collaborative aquaculture projects in the region using science-based tools and information, while educating the public, news media and decision-makers about the social, economic and environmental effects of aquaculture.

The project will be led by Connecticut Sea Grant and the University of Connecticut. In addition to RWU Law and URI, partners include Rhode Island Sea Grant; Woods Hole Sea Grant; the New England Aquarium; the UConn Center for Land Use Education and Research; the National Marine Fisheries Service office in Milford, Conn.; Clark University; and the George Perkins Marsh Institute.

East Coast project to boost oyster breeding

October 16, 2019 — A dozen East Coast universities and federal science groups have been awarded a five-year, $4.4 million contract by NOAA to advance selective breeding of oysters for aquaculture.

The Eastern Oyster Breeding Consortium is led by longtime colleagues and collaborators Stan Allen of the Virginia Institute of Marine Sciences and Ximing Guo of Rutgers University, who in 1994 made a first breakthrough with breeding tetraploid oysters, a building block for today’s aquaculture industry.

Research at the Rutgers Haskins Shellfish Laboratory and the VIMS Aquaculture Breeding and Technology Center used traditional breeding techniques to develop strains of  Eastern oysters that are now quite resistant to MSX, a parasitic disease that for decades depressed oysters harvests.

In pockets where old oyster beds survived, MSX tended to weaken and kill new shellfish within a couple of years. The development of resistant strains enabled a modest revival that today has grown to a $90 million aquaculture industry, with a growing economic impact from the Carolinas to Maine.

European seafood sector fights back against claims of IUU-tainted fishmeal

October 16, 2019 — NGOs and retailers are seeking to distance themselves this week from a new report prepared by the Dutch-based Changing Markets Foundation, which claims to have found links between them and unsustainable fishing operations in Africa and Asian countries that supply feed ingredients for aquaculture.

Changing Markets undertook a comprehensive mapping exercise of fishmeal and fish oil supply chains from sea to plate, which is set out in the report “Fishing for Catastrophe.”

Tide to Table: The Rise of Ocean Farmers

October 15, 2019 — The following was released by NOAA Fisheries:

There is a growing interest in understanding where our food is coming from and in supporting local farmers. There has also been an increased focus on local fare on many menus at eateries coast to coast. In fact, the once-obscure term “locavore” is now in the dictionary and is a highlighted feature on menus. When thinking about farm-to-fork many envision rolling hills, red barns, and a farmer in overalls tending his or her flock. But what about a farmer in waders or swim trunks? Can we trade the rolling hills for blue waves and the barn for a boat? That is just what the tide-to-table farmers are hoping to do.

Aquaculture, also known as farming in water, is the fastest growing food production system in the world. In the United States, aquaculture farmers raised and harvested more than 80 million pounds of seafood in coastal waters and the open ocean. These farms can vary from seaweed production in Alaska, oyster gardens in New England, and even offshore farms in the clear waters of Hawaii.

Seafood is vital to the Hawaiian economy and culture. Fish, shellfish, and seaweeds are an important part of local diets. Seafood demand is further increased by millions of visitors who crave high-quality, fresh, and local seafood.

Blue Ocean Mariculture, the nation’s only offshore fish farm, is located just off the rocky Kona coast. It is helping provide a native Kanpachi species to meet this growing demand for seafood. “Among local species, Hawaiian Kanpachi was a clear choice for its high quality, versatility, and natural ability to hit sustainability benchmarks,” said Blue Ocean Mariculture farmer Tyler Korte.

The fish, marked by dark blue-green upper body and a lavender-tinted belly, are grown in floating pens that can be raised and lowered in the water column. The series of pens on the farm can grow around 900,000 pounds of fish a year.

“Restorative aquaculture” potential greatest in North Sea, East China Sea, and Southern California

October 15, 2019 — Combined commercial shellfish and seaweed aquaculture have significant potential to provide sustainable food and jobs while restoring marine ecosystems in Europe’s North Sea, the East China Sea, and Southern California.

A new study published in PLOS ONE finds that every inhabited continent has marine regions well-suited for the kind of shellfish and seaweed aquaculture that benefits both ecosystems and people by filtering polluted waters, providing habitat for commercially valuable species, and generating steady food and jobs. For shellfish, the potential was greatest in Europe, Oceania, and North America, while for seaweed, it was greatest in Europe, Asia, Oceania, and South America.

Another outside crab species turns up in Maine waters

October 15, 2019 — A scientist with an environmental group says she has found what she believes is the first recorded appearance of a potentially damaging species of crab in Maine waters.

Marissa McMahan of the Massachusetts-based group Manomet said she located the smooth mud crab this month on a research trip. The crabs are typically found south of Cape Cod, Massachusetts. They can pose problems for aquaculture businesses because they prey on young oysters — a species of high economic value that is grown in Maine.

McMahan collected the single specimen, and it’s still alive. She said it’s too early to know how the animal ended up in the New Meadows River in West Bath, but it’s important to monitor for more of them.

US retailer Publix audits seafood suppliers’ sustainability answers

October 11, 2019 — Publix Super Markets, a Lakeland, Florida-based retailer with more than 1,200 locations in seven southern US states will begin, in 2020, to “reverse audit” some of its many seafood suppliers for their sustainability claims.

“We expect them to be in compliance and [to] find no errors,” Guy Pizzuti, the company’s seafood category manager, told Undercurrent News in a recent email exchange.

The reverse audit process will take an item code and lot number and work backwards through the system, he explained. In instances where aquaculture-related suppliers are found out of compliance, the company will meet with both the supplier and the Best Aquaculture Practices (BAP) program, he said.

“Corrective actions would be submitted, audits would be increased, and [the] business would be reduced or eliminated [from the supplier list] pending any further issues. BAP will be asked to demonstrate findings to both Publix and the supplier.”

URI researchers awarded multiple grants to study aspects of aquaculture industry

October 10, 2019 — Several scientists at the University of Rhode Island have been awarded grants to study oyster genetics, breeding and diseases as part of a region-wide effort to support the growing oyster aquaculture industry in the Northeast and assist efforts to restore wild oyster populations.

“Wild and farmed oysters are facing major threats from water quality and disease,” said Marta Gomez-Chiarri, a URI professor of animal science who has studied oyster diseases in Narragansett Bay for more than 20 years. “Even though local water quality has improved in Rhode Island, oysters across the United States face localized threats from pollution and eutrophication while at the same time dealing with multiple factors of global ocean change, like ocean acidification, as well as changes in salinity and dissolved oxygen. We are only beginning to understand the effects of these multiple stressors.”

Gomez-Chiarri — along with URI Assistant Professor Jonathan Puritz and U.S. Department of Agriculture scientist Dina Proestou — have teamed with shellfish geneticists and breeders from 10 other East Coast universities to form the Eastern Oyster Genome Consortium to develop genetic tools to accelerate selective breeding efforts. The consortium, in a proposal led by Rutgers University, has been awarded a $4.4 million grant from the Atlantic States Marine Fisheries Commission to accelerate the pace of identifying the genes responsible for desirable traits like disease resistance.
