Coho salmon have a secret weapon against sea lice: their skin swells up around sea lice causing them to drop off or die! But we previously didn't know which cell types were responsible for this epic delousing strategy...and there's a lot of different cells in the skin! 2/

Ever wonder why sea lice wreak havoc on Atlantic salmon but leave coho unscathed? The secret is skin deep! Read more in our latest paper: "Keratinocytes drive the epithelial hyperplasia key to sea lice resistance in coho salmon" published @BMCBiology!🧵 bmcbiol.biomedcentral.com/articles/10.11…

A 2 -yr postdoc position is available in the group of Daniel Ruzzante at Dalhousie Univ. pending a successful funding application. Experience in pop genetics w successful publ. record and proficiency in bioinformatics and analysis of lcWGS a MUST. Visit ruzzante.ca/no-title/

Atlantic herring genetic structure is restricted to small parts of the genome. Genotype-environment associations show a putative inversion relates to a latitudinal pattern of winter seawater temp with @apfuentes7 @Ruzzante_Lab @xtinabourne @rystanman doi.org/10.1111/eva.13…

#FSBI2024 its over! Many thanks to everyone who came to #Bilbao, to the team of volunteers and many workers involved, @TheFSBI for the support. Also, to these two wonderwomen of whom I feel so proud and inspired @mgintxausti and @naiara_re in @azti_brta we are lucky to have you😘

And last but not least, thanks to all of you who attended. You are the reason #FSBI2024 exists. 🐟🥂 Here's to many more years of shared #fishscience!

Many congratulations to @mLisetteDelgado for winning best talk at #FSBI2024! 🎊🥂🐟🧬 @fsbi_symposium @TheFSBI @Ruzzante_Lab

@samvbeck identified the genomic regions and environmental variables driving return run timing variation in 🇨🇦 Atlantic Salmon. Pops with the most extreme run times may be most vulnerable to climate change due to ⬆️ genomic offsets! 🐟🧬⏰ @fsbi_symposium @TheFSBI #FSBI2024

@TheFSBI #fsbi2024 @Salisbury_Fish Sarah Salisbury giving a fantastic presentation on single cell RNAseq showing that Coho salmon and pink salmon have strong resistance to sealice

A great introduction to close kin mark recapture by @Ruzzante_Lab who ground-truthed this technique using Brook Trout populations and is now applying CKMR with PhD candidate @allelellie to assess population size of commercially important halibut. @TheFSBI #FSBI2024 🐟🧬

Fabulous talk by @mLisetteDelgado at #FSBI2024 who combined historical genomic and telemetry data to reveal a collapse in genetic diversity in Canadian cod between the 1990s and the 2010s, potentially due to a reduction in the year-round inshore cod ecotype. @TheFSBI 🐟🧬🗺🍁

A further welcome to delegates from @naiara_re, who highlights the landmark occasion of this being the first FSBI symposium outside of the UK and Ireland! The excellent turnout was also praised for what could have been a narrow subject field: omics. Welcome #FSBI2024!

A lovely end to yesterday, with drinks and food around the sailing boats in itsamuseum, Bilbao! Hopefully, everyone is bright-eyed and bushy tailed this morning! #FSBI2024

Clarke et al. @molecology 2024. 'Global assessment of effective population sizes: Consistent taxonomic differences in meeting the 50/500 rule' An interesting read! #conservation #genetics onlinelibrary.wiley.com/doi/10.1111/me…

Curious to know what effective population sizes looks like across the globe? Look no further! Out now in Molecular Ecology, our team assessed effective size of wild populations, comparing between taxonomic groups and in relation to the 50/500 rule. bit.ly/3TYrhEa

@ClareVenney @scas_scsa Oops! Was looking forward to your presentation this afternoon. Hope you feel better soon
