First big conference this week at #fsbi2026, where I presented my early first chapter results with a poster and a flash talk 🐟 thank you @thefsbi.bsky.social for the opportunity!

David Murray (cefas) very clear explanation of challenges of jargon in population genetics when communicating with policymakers #FSBI2026

So many wonderful, thought provoking talks at #FSBI2026! From weird economics to shark tooth jewellery to tagging to metapopulations to stakeholder engagement to fisheries management. So diverse and interesting!! @thefsbi.bsky.social

A taster of the @projectfishistory.bsky.social from @alecbmmoore.bsky.social, digging out some especially revealing #historical #ecological facts on #herring (never forgotten) spawning grounds in the #IrishSea. #FSBI2026

This morning we are lucky to have Steven Cooke kicking off the session: "Fish Behaviour & Physiology in Conservation". He talks about interdisciplinary in fish biology and why it's needed to meet the challenges of the 21st century. You can read more, here: doi.org/10.1139/face... #FSBI2026

Fuelled up from lunch and ready to go! Opening the "Fish & Human Health" session we have our next keynote, Ioanna Katsiadaki! Ioanna talks about the importance of fish as a healthy food. However, heavy metal contamination like mercury, POPs and other emerging contaminants threaten this #FSBI2026

Masterful overview of the current risks to #fish and #human #health and ways forward to avert them! By #IoannaKatsiadaki #FSBI2026

The role of #Oxygen in preserving vivid #colours in #packaged #yellowtail fillets. By #YaoWang #FSBI2026 #Seriola

Finishing today, our distinguished medallists!🏅Esteban Nogueira, this year's Huntingford Medallist for most impactful paper by an ECR in the Journal of Fish Biology, told us about: The theory of island biogeography and the stability of oceanic reef fish communities doi.org/10.1111/jfb.... #FSBI2026

🏅 Last but not least, we heard from Simon Jennings, this year's Beverton Medallist, awarded to a distinguished scientist for lifelong contribution. Simon talked about importance of identifying difficult questions then fitting the right tools as well as spotting happenstance opportunities #FSBI2026

🏅 We also heard from this year's Le Cren Medallist, Adalberto Luis Val, awarded for lifelong contributions to conservation, training, or public understanding of fish biology. Adalberto took us on his research journey through the Amazon, in his truly charismatic style! #FSBI2026

Award for the most entertaining slides of #FSBI2026 might have to go to @salisburyfish.bsky.social! Interesting work looking at shared and divergent responses of salmonids to sea lice attack.

Congratulations to @lsoler.bsky.social who presented an excellent poster and flash talk at the #FSBI2026 symposium! Her single cell RNA sequencing results revealed how resistant and susceptible salmonids differ in their systemic immune responses to sea lice. 🐟🧪🧬🧑‍💻 @thefsbi.bsky.social

We’re graced by @bd-stew.bsky.social telling us recent stories of #marine #faunal changes around the Southwest of England and their impacts on human communities. (With an added picture of the many octopuses being caught in Brittany a couple of years before the UK #bloom!) #FSBI2026

Putting finishing touches to talk on @projectfishistory.bsky.social - looking forward to #FSBI Southampton @thefsbi.bsky.social

Flanagan et al. test the macroevolutionary stability of the transcriptomic response to a standardized immune challenge in 14 ray-finned fish; conserved phenotypic responses are associated with highly flexible gene regulatory architecture. 🔗 doi.org/10.1093/molbev/msaf323 #evobio #molbio

Cinnamon and chocolate: a combination to die for. Brushtail possums, invasive in NZ, can normally be trapped easily. But the most trap-shy animals are a problem: how to target the last few? Turns out, special edition cinnamon Oreos. More addictive than drugs. 🧪🌍 predatorfreenz.org/research/ore...

Oreos and uppers: inside the research to get the last 1% of predators

To achieve Predator Free 2050, every last individual predator needs to be caught – and the final few are often the hardest.

Pigs edited at CD163 to be resistant to Porcine Reproductive and Respiratory Syndrome Virus approved by Health Canada! www.cbc.ca/news/health/...

These gene-edited pigs can go to market, Health Canada says | CBC News

Food made from pigs engineered to be resistant to a porcine virus are as safe and nutritious to eat as pork currently on the market, Health Canada said Friday.

I’m excited to share our new paper in Ecology! Our 9‑year study across an urban–rural gradient shows native trees, especially oaks, boost blue tit breeding success. More native foliage supports more of the birds preferred prey and improves reproductive success. 📃 doi.org/10.1002/ecy.... #ornithology

Native trees are related to advanced bird breeding phenology and increased reproductive success along an urban gradient

Urban areas are altered from natural landscapes in several ways that can impact wildlife. Birds are widespread in urban areas, and it is well documented that there are phenotypic differences between ...

How do nanoparticles traverse the endothelial barrier in a living organism? We explored this fundamental question using the zebrafish and PEG-based nanoparticles (NPs) in our latest article: (pubs.acs.org/doi/10.1021/...).

Trans-Endothelial Trafficking in Zebrafish: Nanobio Interactions of Polyethylene Glycol-Based Nanoparticles in Live Vasculature

Trans-endothelial transport of nanoparticles remains poorly characterized in live organisms. The zebrafish is a well-established model for direct in vivo imaging; however, standardized controls have n...

Excited that our newly described Okanagan Crayfish makes an appearance on the CBC's cool species of 2025 list: www.cbc.ca/news/science...

Tarantula with XXL genitalia, 'death ball' sponge among cool species of 2025 | CBC News

A spider with extraordinary genitalia, a carnivorous caterpillar that wears its prey's body parts, and a tiny opossum are among the cool new species described by science in 2025.

I am very excited to share the first Accorsi lab publication: a collection of detailed protocols to maintain an apple snail 🐌 colony and generate stable mutant lines. The video is coming soon @ JoVE! We hope this will be a valuable resource for the community. app.jove.com/t/69267/the-...

I am very excited to share our new paper with my amazing co-authors and mentors @dmacguig.bsky.social @fishgenomes.bsky.social @tjnear.bsky.social . We investigate a secondary contact zone in #darters. track.smtpsendmail.com/9032119/c?p=...

Mosaic tri-lineage secondary contact shapes diverse genomic outcomes in darters

Abstract. Speciation does not always lead to complete reproductive isolation, which can result in hybrid zones with gene flow. In freshwater fishes, second

Congrats to @pfschwarz.bsky.social on publishing her undergraduate honors thesis work on darter hybridization! There is evidence of ecological specialization of two sister species. She also compares lcWGS and RAD-seq data for the same samples and finds tighter distribution of Fst estimates w/ lcWGS

I've slowly been reformatting notes from my population and conservation genetics course at Montana State University into a web book—a rough draft is now live here: elinck.org/popgen_conge...

Day 19’s #25DaysofFishmas feature wouldn’t feel out of place at Santa’s Workshop! ❄️ We trade a our road-trip car for a seaplane and head north - very north - to Alaska and the Alaska Blackfish (Dallia pectoralis), a tough-as-ice fish that breathes air and has been described as “a bulldog with fins”

Excited to launch the new improved Reproducible Code guide from @britishecologicalsociety.org @methodsinecoevol.bsky.social FREE online here! www.britishecologicalsociety.org//wp-content/... Amazing work by some very talented ECRs. We hope it’s useful!

Glad to have the final version of this out! Advice for anyone with low coverage genomes wanting reliable measures of inbreeding 🧬

Team fish - we need your help! We are trying to build a database of all the fish chromosome-scale genomes where sex chromosomes have been identified. Have you build one or some? Do you know someone who has? Can you post the link in the comments? Please spread the word and repost! Thank you!

Great talk by @chantellehooper.bsky.social who presented her work investigating microbiome changes in healthy and languishing shrimp at the Cefas Student Day @cefasgovuk.bsky.social! 🦐🧬🦠
