Trial shows Calysta’s FeedKind can replace 30 percent of fishmeal in yellowtail feed

April 26, 2021 — A trial at Japan’s Kindai University has shown that Menlo Park, California-based Calysta Inc.’s FeedKind bacterial protein meal (BPM) can replace up to 30 percent of fishmeal protein – or up to 20 percent of total feed – in the diet of yellowtail without any impact on growth rate, digestibility, daily feeding rate, or feed efficiency.

The paper, “Methanotroph (Methylococcus capsulatus, Bath) bacteria meal as an alternative protein source for Japanese yellowtail, Seriola quinqueradiata,” written by a group of researchers led by Amal Biswas, was published in the journal Aquaculture. It details two trials – one of 1,500 yellowtail fish, and the second of 800 – analyzed over an eight-week period. In both cases, a control diet was used alongside increasing concentrations of FeedKind. Fish survivability was 100 percent across all tests, with no significant difference between the control diets and the 25 percent inclusion rate across both trial groups.

Nicole Naar: Building an Accessible Aquaculture Network

April 22, 2021 — The following was released by NOAA Fisheries:

Dr. Nicole Naar is an Aquaculture Specialist at Washington Sea Grant. She earned her doctoral degree in anthropology from the University of California-Davis, where she conducted fieldwork in Mexico and Tanzania. Currently her work focuses on conducting outreach for sustainable aquaculture and helping coastal communities respond to social and environmental challenges.

Blending Marine and Social Sciences

Growing up in Florida, Naar always had an interest in marine biology. In high school, she also developed an interest in social science. At the time, it seemed difficult to find a link between the two career paths. Luckily, on a student trip to Mexico, her eyes were opened to the possibility of combining anthropology, sustainability, and marine biology in a coastal setting.

One of Naar’s visits to Mexico focused on a small coastal town where many job seekers came from other areas of the country to work and fish. Fisheries were rumored to be overexploited due to the growing number of immigrant workers. To address these concerns and perceptions, Naar began to gather data on resource use, regulation compliance, and other factors. Ultimately, her work demonstrated that in terms of fishing practices, there was no difference between locals and non-locals.

“Fisheries are directly connected to the social science issues many people care about, such as job creation, local food systems, and environmental sustainability,” said Naar. “Social science research provides data that empowers communities to make informed decisions about sustainable wild-capture and aquaculture.”

Cleaner fish from salmon farming affect wild populations

April 21, 2021 — A growing demand for cleaner fish in salmon farms raises concerns about overfishing and human-mediated geneflow to wild populations. A recent study reveals that up to 20 percent of the local populations of corkwing wrasse in mid Norway may constitute escapees and hybrids.

Every year, millions of wrasses are caught along the Swedish and Norwegian coasts, and transported to  for parasite control. Effects on the wild harvested populations, and the risks from  escaping the farms, are poorly investigated.

Two recently published studies take a closer look at how the current fishery is affecting source populations and ecosystems, and to what degree translocated fish are escaping and mixing with populations outside the fish farms.

Baby elvers rocket back up in value in Maine

April 21, 2021 — Tiny baby eels are worth big bucks again in Maine.

The state is home to the U.S.’s only significant fishery for the baby eels, which are called elvers, and it’s taking place right now. Prices tanked last year due to disruption to the worldwide economy caused by the onset of the coronavirus pandemic.

This year, the fishery is experiencing a return to normalcy. The tiny, wriggling fish are worth $1,634 per pound to fishermen, the Maine Department of Marine Resources reported on Monday.

The elvers are worth so much because of the crucial role they play in Asian aquaculture. They’ve been worth between $1,300 and $2,400 per pound every year since 2015, except last year, when they were worth $525.

The elver business has benefited from improved health in international trading at large, said Mitchell Feigenbaum, an elver dealer.

“There’s confidence in the market in all commodities right now,” Feigenbaum said “There’s a crazy boom in real estate, a crazy boom in the stock market, a crazy boom in the eel market.”

Global Aquaculture Alliance changes name to Global Seafood Alliance

April 20, 2021 — The Global Aquaculture Alliance announced on 20 April that it has officially changed its name to the Global Seafood Alliance, following a vote by its board of directors and the board of directors of its sister organization, Global Seafood Assurances.

GAA launched Global Seafood Assurances in 2018 as a nonprofit addressing marketplace expectations and assurance involving environmental responsibility, social responsibility, food safety, and animal welfare for both farmed and wild-caught seafood. The United Kingdom’s Sea Fish Industry Authority (Seafish) signed a memorandum of understanding with the nonprofit to address a gap in certification, before ultimately signing over the Responsible Fishing Vessel Standard.

MAINE: Aquaculture, traditional fishing square off at public hearing on bill to review Maine’s lease process

April 14, 2021 — Tensions over Maine’s aquaculture industry again spilled into the Legislature on Tuesday as lawmakers held a public hearing on a proposal that would conduct a broad review of the way state regulators approve leases.

The bill is a concept draft that seeks a sweeping overhaul and review of how aquaculture projects are vetted and approved by the Maine Department of Marine Resources.

Critics say the approval process of projects along Maine’s vast coastline is too permissive, resulting in sprawling aquaculture farms that conflict with the state’s traditional fishing industries, such as lobstering.

Jon Lewis, a Boothbay resident who worked as the agency’s director for aquaculture for 23 years, told lawmakers on the Legislature’s Marine Resources Committee that the disputes over projects are on the rise.

MAINE: Sea farmers say bill to prevent large-scale aquaculture could hurt entire industry

April 14, 2021 — A Maine legislator who hopes to stave off industrial aquaculture and protect lobstermen and women from what he sees as a “large storm” headed for the industry is proposing a bill that small aquaculture farmers say could sink them.

The bill proposed by Rep. Robert Alley, D-Beals, aims to “protect Maine’s ocean waters, support robust regulatory oversight and the long-term health of the aquaculture industry,” according to a concept draft considered by the Committee on Marine Resources Tuesday.

The bill would revamp the permitting framework for state aquaculture leases, restricting the size of a lease and the number of leases and acres a person can hold, along with requiring leases be turned over to the state when they expire and removing an exemption from the Natural Resources Protection Act for leases over 5 acres. The bill also would prompt a review of the resources available to the state Department of Marine Resources’ aquaculture division.

Alley’s bill also would require that the department “convene stakeholder meetings to develop a strategic aquaculture plan with input from leaders in the aquaculture, lobster, fishing, tourism and recreation industries, as well as experts from the environmental and water quality regulatory community.”

While preventing large-scale aquaculture seems to be a primary goal of the proposed legislation, L.D. 1146, small sea farmers told committee on Tuesday that the changes would hurt them.

China’s dietary advisory body calls for more seafood consumption to improve health

April 14, 2021 — China’s national dietary advisory body has suggested the country needs to eat more seafood in order to reduce chronic diseases like heart disease and diabetes, which are on the rise.

In its annual report on national dietary problems, the China Nutrition Society, a research group attached to the ministry of civil affairs, said the national average daily intake of seafood of 24.3 grams was low by international standards and should rise to 40 grams. It also called for a reduction in sodium and sugar intake, which it blames for a rise in diabetes and coronary artery disease in China.

Congress urged to back aquacultural expansion

April 6, 2021 — A seafood pressure group is calling on the US Congress to support the expansion of the country’s aquaculture sector in order to benefit the American economy, industries and communities.

Through a new industry campaign titled “Essential Aquaculture,” Stronger America Through Seafood (SATS) aims to create a sense of urgency for Congress to act swiftly on aquaculture.

“As Congress debates ways to address the many pressing challenges we face, including economic recovery, food security and environmental challenges, aquaculture should be considered as one of the solutions,” said Margaret Henderson, Campaign Manager of SATS.

“The expansion of American aquaculture is essential to the US economy. Aquaculture can strengthen American communities by supporting new jobs and a diverse workforce in a post-pandemic world. Increased seafood production would also ensure families have a steady supply of affordable American-raised seafood produced sustainably with minimal impact on the environment, which is essential to climate and conservation efforts.”
