If you happen to be in northern Iceland tomorrow, drop by the seal center for some presentations from researchers around Iceland, there will even be something about lumpfish. selasetur.is/en/5th-isc-s...

A superb video from the Lump Now project at DTU Aqua (Denmark) of the moment a lumpfish releases its eggs. www.youtube.com/watch?v=l9z8...

A nice whiting ()Merlangius merlangus) caught during the Icelandic groundfish survey @mfri.bsky.social . While the range of this species reaches northern Iceland, it is not as common than other areas of Europe, and there is no targeted fishery.

Out on the Icelandic groundfish survey and here just a few of the fishes we get at the deeper stations ~400 m. (1/n) Sea tadpole - Careproctus reinhardti Greater eelpout - Lycodes esmarkii Doubleline eelpout - L. eudipleurostictus Arctic eelpout - L. reticulatus Vahl´s eelpout - L. gracilis

Today at 12:10 GMT I will provide insight into the wonderful life of a lumpfish.

Want to know more about lumpfish (Cyclopterus lumpus), join me online or in person on Friday 13th for my talk at the University of the Westfjords. www.uw.is/en/events/vi...

My first ever attempt at #SundayFishSketch. Atlantic mackerel (Scomber scombrus).

My poster is currently being printed, this is the joy I will endure in the coming days.

IT'S ADORABLE! New fish species just dropped: the bumpy snailfish at 10,000 ft down in the ocean gift link: www.nytimes.com/2025/09/08/s...

With two above average year classes entering the fishery, ICES advice for Norwegian spring-spawning herring increases by 33 % to 533 914 tonnes. doi.org/10.17895/ice...

After years of coastal states failing to agree to a shared TAC for Atlantic mackerel, leading to catches > advice, ICES advice for 2026 is 71 % lower than in 2025. doi.org/10.17895/ice...

👩‍🔬BioProtect PhD student Marjolijn Rika Nijzingh collected 325 #eDNA samples at 37 sites (0–500m) around 🇮🇸 aboard RV Árni Friðriksson. The data will reveal the presence of fish, mammals, corals & more, a big step for #30x30 goals! Amazing job Marjolijn!👏 #MissionOcean #HorizonEU @mfri.bsky.social

I get that the news cycle is packed right now, but I just heard from a colleague at the Smithsonian that this is fully a GIANT SQUID BEING EATEN BY A SPERM WHALE and it’s possibly the first ever confirmed video according to a friend at NOAA 10 YEAR OLD ME IS LOSING HER MIND (a thread 🧵)

PhD opportunity @sosbangor.bsky.social on managing scallop fisheries to find the balance between conservation and fisheries yield. Get in touch if you're interested and I will email you the project description.

A whole podcast dedicated to lumpfish!!!

Estimated age at which northeast Arctic and North Sea cod mature has decreased over time. This was considered to be a result of fisheries induced evolution whereby fisheries caught older fish, so fish which matured younger were more likely to spawn. 1/n

More interesting Greenland shark reproduction tidbits - Male do not mature until they are at least ~2.6 m - Females do not mature until they are at least ~3.9 m - It is estimated that they produce 200–324 pups per pregnancy - new born pups are 35-45 cm journals.plos.org/plosone/arti...

1/n Fascinating study collating records of Greenland shark across the Atlantic – males and subadult females found in cold arctic water – adult females reside in warmer Atlantic water – large juveniles are common both in high-Arctic and temperate areas onlinelibrary.wiley.com/doi/10.1002/...

Every so often I come across a big weird fish I haven't heard of that is so odd and delightful it feels like a gift from the universe to me personally. Anyway I somehow went 25 years without hearing of Gasterochisma, this big bizarro primitive tuna beast. Lovely stuff.

Lumpfish spawn around the coast of the Nordic countries, with the young migrating away from the coast as they grow. New research shows that temperature is the main driver of lumpfish distribution in the Nordic Seas. More here: www.hafogvatn.is/en/about/new... #lumpfishresearch #marinebiology

www.nature.com/articles/s41... Loving this paper on recent collaboration between Cefas and partners, including @universityofexeter.bsky.social ...in essence, tagging of a tuna that got eaten by a whale 🍣

🏊 Swimmer #RossEdgley is taking on 1,000 miles in 100 days - alongside killer whales 🐋 through 130ft waves 🇮🇸 🌊 🧑‍🔬 This epic #swimforscience is also an innovative #citizenscience mission‼️ 🧬 Ross will collect #eDNA for 🧐 in #BioProtect in 🤝 with @mfri.bsky.social & @matisiceland.bsky.social 🤗 Coming 🔜

Ross Edgley will attempt a historic first: 1,610 km swim around the entire coastline of Iceland. Along the way, his support vessel will collect eDNA samples, and conduct microplastic monitoring, and marine mammal identification.

Friends, I am seeking a historian in either Irish or Scottish lore specialized in leviathans, basking sharks, or any other marine creatures.

New from the Near Lab, led by @chasedbrownstein.bsky.social "The many origins of extremophile fishes" We explore the phylogenomics and evolutionary history of the lovely and bizarre eelpouts, ronquils, pricklebacks, and wolffishes (Zoarcoidea). royalsocietypublishing.org/doi/10.1098/...

When lumpfish are not at the coast spawning (Cyclopterus lumpus), where are they? Turns out, almost everywhere in the Nordic Seas. New paper documenting the summer distribution of lumpfish doi.org/10.1111/fog..... (1/n) @mfri.bsky.social

Meet the Manefish, Caristius macropus. Named for their distinctive shape, macropus means large foot. This fish was observed in Monterey Bay 483 meters (1584 feet) deep in August of 2018. #MBARIFromTheVault

Proud that my article on lumpfish migration made Editor´s choice on Journal of Fish Biology. onlinelibrary.wiley.com/toc/10958649...

A nice catch of Arctic eelpouts, Lycodes reticulatus, north of Iceland.

At our most northern stations of the survey we caught a few Lycodes seminudus. The Latin name describes it as semi naked because it has scales only on half its body. The common name in both Icelandic and Danish translates as half-naked eelpout, but in English, the longear eelpout.

115 cm, 16 kg, Northern wolffish (Anarhichas denticulatus) caught north of Iceland. Northern wolffish have very watery flesh to bring their body close to the density of water. This allows them to easily move away from the sea bottom into the pelagic zone.

Some nice juvenile haddock (Melanogrammus aeglefinus) a common fish here in the north Atlantic and found all around Iceland. So many pictures looked washed out and don´t give credit to how colorful this fish actually is, check out that tail.

The Iceland march groundfish survey, ~500 stations surveyed annually to collect information of the bottom dwelling species down to depths of 500 m. The map can be viewed live at skip.hafro.is. @mfri.bsky.social

New paper out: The tale of the founder flounder 🐟 link.springer.com/article/10.1... We identify the geographic origin of alien flounder in Iceland, and discuss potential implications on the flounders’ status & hybridisation ❓👀 @fishiceland.bsky.social @mfri.bsky.social

MFRI´s new research vessel, Thorunn Thordardottir HF 300, is on its way to Iceland. It is named after a pioneer of research on primary productivitym Thorunn Thordardottir. See more on MFRI´s website (in Icelandic): www.hafogvatn.is/is/moya/news... #marineresearch #researchvessel

New paper (doi.org/10.1016/j.rs...) looking at changes in the female lumpfish (Cyclopterus lumpus) gillnet fishery in Iceland in terms of effort in the past 34 years and a look at how to improve the management of this effort based fishery. Published just in time for the switch to a TAC 😉.

Come join us here in Ísafjörður, careful though, after coming here to study, a few never leave.

While this one is pink, leaf scorpionfish come in an array of colours, including green, red, brown, yellow, and white. Their name comes from their leaf-like shape – flat and perfect for blending into their surroundings 🐠🍂🌈 🎥: Ibbe Shifan

New study out from Charlotte Matthews "Biology of One of the Most Abundant Mesopelagic Fish in Icelandic and Surrounding Waters: The Krøyer's Lantern Fish Notoscopelus kroyeri (Malm, 1861)" onlinelibrary.wiley.com/doi/10.1111/... @christophe-p71.bsky.social

We have reached day 25 of #25daysoffishmas and we draw to a close with my subject of study, Cyclopterus lumpus, which actually lacks a full common name and is simply called "lumpsucker". This species really stands out from the rest of the family, in terms of appearance, size and behaviour.

On day 24 of #25daysoffishmas we have Brashnikov's lumpsucker, and again, a species with very few specimens. Given the controversies in the lumspucker family, a few more specimens could certainly help tidy things up a bit.
