Remote underwater gliders—or underwater drones—present opportunities for all kinds of data collection and oceanographic research. They're incredibly cost effective, requiring less staff and equipment than traditional methods. They can remain deployed longer than a ship can be out, and they can go places where a ship can't go. And, you can pilot them anywhere with a laptop and an internet connection—even from your couch!
On our latest podcast, we talk with Jen Walsh, a research biologist and glider pilot for the Southwest Fisheries Science Center. She talks about how we're using gliders in remote areas, like Antarctica, and how they're changing the way we collect fisheries data and learn about the ocean.
The research vessel Árni Friðriksson has completed a week-long capelin survey off the northwest coast of Iceland, focusing on spawning migrations and stock abundance. Survey coverage extended from west of Dohrnbank along the continental slope off the Westfjords to Skagagrunn.
At the same time, the vessel Þórunn Þórðardóttir gathered acoustic data during a hydrographic survey examining ocean conditions around Iceland in February. Scientists reported almost no capelin north of Iceland. A small quantity of mature capelin was detected near the continental slope at Bardagrunn, while immature fish were observed farther offshore near drift ice off the Westfjords.
Researchers estimate that the bulk of the 328 thousand tonnes of capelin recorded northwest of Iceland in January has now migrated eastward, moving clockwise around the country. The stock is expected to spawn in coastal waters in the south and west in March.
The Marine and Freshwater Research Institute has announced no further capelin surveys will be conducted this winter.
The Aquaculture Stewardship Council (ASC) has welcomed the expansion of Iceland Foods’ certified seafood range, signalling a growing shift among UK retailers to make responsibly farmed seafood both accessible and affordable.
Launching on 10 February, Iceland’s expanded selection of ASC-labelled products reflects rising consumer demand for seafood that protects both people and the environment — without carrying a premium price tag.
The latest rollout increases Iceland’s total ASC-certified range to 15 products, adding newly certified salmon, seabass, scallops and prawns. Several items will be included in multi-buy promotions, reinforcing the retailer’s commitment to keeping sustainable choices within reach of everyday shoppers.
Ecuador's non-oil exports reached a record high in 2025 thanks to shrimp, while the industry warns of new regulations.
During 2025, Ecuador achieved a historic record in non-oil exports, totaling USD 29.402 billion, representing an 18.3% increase compared to the previous year. This result was led by the performance of shrimp, which consolidated its position as the country's main export product, along with the contribution of canned fish.
Shrimp topped the ranking of exports with USD 8.401 billion, registering a year-on-year increase of 20.2%, and confirming its status as the main driver of growth in Ecuador's non-oil sector.

A new study led by researchers at University of Stirling has found that changes in aquafeed composition over the past two decades have significantly reshaped the environmental footprint of European aquaculture, reducing reliance on wild-caught fish while increasing impacts across several other environmental indicators.
The research, led by Björn Kok and Dr Wesley Malcorps of the university’s Institute of Aquaculture, examined developments between 2000 and 2020 and found that the European aquaculture sector cut its overall use of wild-caught fish in feed by 13%, despite nearly doubling in production over the same period. Growth was largely driven by the expansion of Atlantic salmon farming in Norway.

King salmon farmer leases vessel to support expansion ambitions
New?Zealand?King?Salmon (NZKS) is to introduce the country’s first wellboat, it has announced.
Until now, New Zealand has been the only major salmon-producing country not using this technology.
The 18-year-old wellboat, previously called the Ronja Nordic, has been appropriately renamed the Ronja King. It is currently on its way from Haugesund in Norway to Spain and is expected to arrive in New Zealand waters in April.

The winter storms that battered large areas of the United States in January have had a very noticeable effect on supermarket shelves: more stockpiling, fewer restaurant visits, and a rise in sales value across virtually all seafood categories. This phenomenon was also accompanied by a second decisive factor: an acceleration of seafood-specific inflation, more pronounced than general food inflation.
Data from Circana, analyzed by 210 Analytics, shows the extent to which bad weather can reshape consumption patterns in just a few days.
EJF and Calamasur Want to Put a Stop to Chinese Activity Operating Outside of Scientific Recommendations
“One of the world’s most important squid fisheries is heading toward an ecological and social crisis as vast Chinese fishing fleets take advantage of weak governance, lack of transparency, and regulatory gaps throughout the Southeast Pacific.” Adding to this biological crisis, new research by the Environmental Justice Foundation (EJF) highlights labor abuses by one of the companies involved—China National Fisheries Corporation—whose catches are exported to the US, the European Union, and the UK.

What sounds like a terrible idea – farming tropical shrimp in chilly northern Germany – is exactly what HanseGarnelen is turning into a high-tech, almost-zero-carbon showcase for “German shrimp”.
HanseGarnelen runs what is currently the largest operational clear-water shrimp recirculation aquaculture systems (RAS) farm in Europe, producing around 100 tonnes of Pacific white shrimp (Litopenaeus vannamei) a year in Glückstadt, northern Germany. After a brush with insolvency and a change of ownership, the company is betting on automation, local branding and continuous improvement to make “German shrimp” a viable alternative to imports.
