The first international workshop that focused on #zebrafish was convened in 1990 in Eugene, Oregon. Sponsored by NIH and NSF, the gathering of ∼40 scientists sought to evaluate the research potential of the tiny fish. Today, nearly 1,800+ zebrafish labs exist worldwide. #ZebrafishFunFacts 🧪

I was recently interviewed by @sciencenews.bsky.social about the discovery of new Antarctic #fish nesting in the fragile Weddell Sea in #antarctica. This time it was the yellow fin notie Nototheniops nudifrons nesting, likely in groups! 🧪 🌎 🇦🇶 🐟 🧊 www.sciencenews.org/article/anta...

🚨 Recruiting 12 PhD students for a new NSF-funded program at the University of Alaska Fairbanks College of Fisheries and Ocean Sciences! This program is for U.S. students who received an Honorable Mention on the NSF GRFP within the last 3 years. @uafairbanks.bsky.social www.uaf.edu/cfos/academi...

@snbogan.bsky.social @notothentoma.bsky.social @scotthotaling.bsky.social @paulbfrandsen.bsky.social et al. explore the evolution of type III antifreeze proteins in deep sea zoarcoid fishes. 🔗 doi.org/10.1093/molbev/msaf219 #evobio #molbio

@notothentoma.bsky.social @arcolon14.bsky.social & @jpostlethwait.bsky.social show how Antarctic white-blooded icefishes, the only vertebrates without hemoglobin, independently lost hemoglobin cluster genes, driven by TEs and repeats. 🔗 doi.org/10.1093/gbe/evaf184 #genome #evolution #TEsky

Excited to share this work, out today in MBE! In polar fishes, we found that antifreeze protein genes expanded in copy number at low temperatures and contracted in the deep sea, highlighting a role of depth and pressure in AFP evolution. 🔗 academic.oup.com/mbe/article/...

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...

First pop gen paper from our lab! We find repeated evolutionary turn over of sex chromosomes in darters contributes to reproductive isolation. Turnover may be an escape hatch to resolve mitonuclear conflict & neo sex chromosomes evolved via a rare recessive mutation. www.biorxiv.org/content/10.1...

Few months ago I commissioned artist @hidet0shi.bsky.social a drawing of the Antarctic dragonfish we described last year, with if possible both the fish and the RV Laurence M Gould as the fish was named after the ship: Akarotaxis gouldae! It turned out so beautiful I made stickers out it! 🧪🌎🐟🧊🇦🇶

While trying to see if two populations of the Antarctic longfin icedevil fish Aethotaxis mitopteryx were genetically differentiated, we uncovered a clear sex signal demonstrating that in this rarely encountered species males are the heterogametic sex! 🧪🐟🌎🐧🧊🧬 onlinelibrary.wiley.com/doi/10.1002/...

First "official" lab meeting in the books at UAB Biology! 🐟🧪🧬

Scientists have asked the NSF to reconsider plans to terminate the lease for its only Antarctic research icebreaker, the RVIB Nathaniel B. Palmer. eos.org/research-and...

The National Science Foundation plans to abruptly end operation of the RV Nathaniel B. Palmer, the sole U.S. research ship capable of braving the farthest reaches of Antarctica and the Southern Ocean. scim.ag/4mB8LOX

Environmental conditions influence life history traits, but what about in Antarctic fish?🐟🇦🇶 We compared two pops of Crowned Notothens Trematomus scotti: one from a fjord of the Antarctic Peninsula and one from the Weddell Sea. Their life histories traits were very different! tinyurl.com/mtmmrv8w 🧪🌎🐧

The Braasch Lab @fishevodevogeno.bsky.social will soon post a position to replace manager of our *Ancient Fish Facility* at Michigan State. Looking for aquaculturist excited for unusual 🐟 species (gar, bowfin, paddlefish, polypterus) + zebrafish. Pls send candidates our way (DM or [email protected])!

Snailfishes and their way to get their eggs protected in the gill cavities of crabs are so awesome!

Happy #worldpenguinday y'all! 🐧🇦🇶 🧪🌎 Here's apparently the only penguin picture I have on my new computer 😅 It's an Adelie Penguin I image in 2014 at Prospect Point (Station J @bas.ac.uk) on the Western Antarctic Peninsula.

And, if you are really keen on what determines sex in fish, check out this graphic novel on the topic from @notothentoma.bsky.social & John Postlethwait, with the help of Sophia Breslin (Now available in 10 languages!): blogs.uoregon.edu/fishsexdeter... 🧪

I was on @rnz.co.nz.web.brid.gy #NinetoNoon this morning talking about joining the @schmidtocean.bsky.social expedition to explore a newly exposed area of #Antarctic #deepsea www.rnz.co.nz/national/pro... #TePapa @pure-ocean.bsky.social

Great opportunities for early career scientists! Please contact me if you have some interests in Antarctic fish and ideas I could help you with!

Very little is known about pathologies in #Antarctic #fish. Recently, during a toothfish survey in the Ross Sea, we found a new #notothenioid fish species infected by a unicellular #parasite of a genus we described few years ago from the Antarctic Peninsula. 🇦🇶🐟🧪🌎 link.springer.com/article/10.1...

White-blooded Antarctic icefishes are unique among vertebrates because they lack functional hemoglobin genes. Their blood transports ~10% as much oxygen as the blood in other teleosts, making them sensitive to hypoxia and an excellent model for human blood disorders. #TeleostTalk 🧪

As work ramps up, we've created a Starter pack to follow members of the consortium. go.bsky.app/QjiXdsc Please comment below to be added!

If you want some distraction and hear about the fish living in Antarctica, I had a great time chatting with Dr Thom @deepseapod.com about my favorite fishes! 🇦🇶🐟 There's a short and a long version depending on how much time you have! And give the other episodes a listen too! They're great!

Firings are happening right now at the National Science Foundation. Essential staff are being cut. This isn’t about the budget. If it was, they’d be going after the military (17%) or state appropriations (38%). NSF is 0.7% of the federal budget. All federal employees make up only 4% of the budget.

For the record, office of polar programs postdoc fellowships at NSF was archived one week before the deadline. new.nsf.gov/funding/oppo... TBD whether it is permanent, but my thoughts are with the people who worked hard on their proposals for months

❄️It's that time of year again!❄️ The Antarctic Science International Bursary is open for applications! £6000 bursaries available to ECRs anywhere in the world for #Antarctic science projects that extend the scope of current work. Deadline 21 March antarcticsciencebursary.org.uk/apply-for-an...

A frenzy of activity as immaculate specimens arrive. The #crinoid is a filter feeding starfish relative. #AntarcticClimateConnections is sampling seabed previously covered in ice that has no associated data; biological, geological, oceanographic, mapping... nada! #Challenger150 #projectESCA

Most people I know would walk outside and think that 32°F is cold. Most people wouldn't think of freezing as an alarmingly hot temperature. It's way to early in the summer for it to be this warm here

For #AntarcticaDay, do you know the #fish that live in the frigid waters around the icy continent?! blogs.uoregon.edu/antarcticfis... 🧪🌍🇦🇶🐟🐠🐡🌊🐧🧊 #sciart #TeamFish

We caught quite a few of them at several occasions, but only when fishing deep, at least by 600m deep!

With so many new people here, I am thrilled to share that I will be opening my lab in the Department of Biology at UAB, the University of #Alabama at #Birmingham in Jan. 2025! 🥳 I will continue to study #Antarctic #fish 🇦🇶 but also explore the amazing local fish diversity of Alabama!🐟🐠🐡

I feel for those poor deep sea fishes!!

The Southern Ocean is one of the coldest on earth and hovers freezing temperatures year-round... What cool #fish live in icy #Antarctica?🧊🐟 Read our new short scientific graphic novel in one of 10 languages to find out! Enjoy! And please share! blogs.uoregon.edu/antarcticfis...

What controls sex development in fish?🐟🐠🐡 Is it a sex gene like mammals? Or are there some other ways sex is determined in #fish? Read our new short #scientific #graphic #novel in one of 8 languages to find out! Enjoy! And please share! tinyurl.com/427tc4nz #sciart #scicomm

For #MolluscMonday, because last week was #fishinresearch week, I thought of presenting an aplysia, which are large sea-slugs used in research to study many aspects of human and animal nervous systems. Here it's Aplysia punctata but A. californica is the one used in research. 🌿#Marinelife

It's #GarWeek!🐟 Gars are awesome! And from a #EvoDevo standpoint their caudal fin is specially cool! We studied gar caudal fin formation and compared it to many other species. So many fish stained and scored, but what a fun project! Links to the articles in the comments! @solomonrdavid.bsky.social

It's #WorldJellyfishDay and #FishFriday, so here are some young fish (Put. Atlantic horse mackerel Trachurus trachurus) finding protection in a Barrel jellyfish Rhizostoma pulmo! I imaged them in August 2010 on the north coast of Brittany, France.

Zebrafish folks (et al.), we posted up our first zebrafish T2T assembly, a Tubingen background HS diploid fish. Polling of the community demonstrated an overwhelming desire for the AB strain to be the next reference genome, but we haven't finished that one yet... www.ncbi.nlm.nih.gov/assembly/GCA...

For #FishFriday, here's a picture of me with one of my fish pictures, displayed in my favorite brewery @Oakshire, and celebrating my last paper with one of my favorite beers: the Ill Tempered Gnome! The paper: doi.org/10.1093/molb...

Ever wondered whether adapting to icy, oxygen-rich #Antarctic waters influenced #hemoglobin gene #evolution in #notothenioid fishes? And how white-blooded #icefish lost their hemoglobin genes? Our new MS is for you! A quick 🧵on our finding in @MolBioEvol! #Marinelife tinyurl.com/5n7ym3jp
