Well done Sarah !
#ISGAXV

Day 4 at #ISGAXV starting with José M. Yáñez (Universidad de Chile) presenting the achievements and future perspectives of genetic improvement in salmonids (coho and Atlantic salmons and rainbow trout) in Chile.
From SNP array development to implementation of genomic selection 🧬🖥️🐟

Really cool presentation at #ISGAXV from Batya Dorfman on disentangling the component of disease resistance (susceptibility transmissibility and survival) of Cyprind fish species to CyHV-3. They looks at infection response in multiple challenge models with 5 carps species

The Genetics and genomic of diseases session is going strong at #ISGAXV 🦐🐟🦪🧬🖥️
We heard from Duwage C.G. Rodrigo (Jeju Uni, Korea) about resistance to M avidus in olive flounders. Polygenic + heritable = genomic selection to improve resistance in the population ✅

Day 2 of #ISGAXV, in the plenary Anna Sonesson from Nofima (Norway) gave us her insights on how to design breeding programmes to integrate gene editing. GE is a very promising tool to increase disease resistance when the causal gene is known, to quickly fix a favourable allele in the population
🧬🐟

At #ISGAXV, Florence Phocas from @umr-gabi.bsky.social just presented their latest results (available in BioRxiv) and identified 63 SNPs explaining up to 74% of the genetic variance after immersion challenges in commercial rainbow trout.
A work done with colleagues from #SYSAAF

Still at #ISGAXV and attending the last session of the day.🧬🖥️🐟🦪🦐
Earlier there was a presentation by Pierrick Haffray (SYSAAF) on accounting for molt stages in genetic evaluation of 🔵🦐. Showing that time to molt was heritable but molt stages wasn't in their dataset (late measurement)

Back from lunch at #ISGAXV and it's time for quantitative genetics and breeding 🧬🖥️ and we started with Cécile Massault presenting her model that captures the additive genetic host-donor interaction in pearl oyster, looking at incorporating it in breeding programme for pearl size 🦪

And the final talk of this morning #ISGAXV is on developing line breeding in tilapia (the aquatic chicken) to fit farmers demand for fish adapted to their market as "one size doesn't not fit all" as Raseh Joshi from GenoMar presented 🧬🖥️🐟
And now, we break for lunch !

Disease resistance is key to sustainable aquaculture and increased animal welfare. In his talk today at #ISGAXV Zhi Weng (Tropical futures institute, James Cook uni) showed that barramundi resistance to SDDV is heritable and can be increasing, in field, through selection using controlled challenge

Does integrating functional annotation data in genomic prediction models improve the accuracy of the prediction? In livestock it depends on the trait, the species, and the type of functional data... With mixed results. We're more and more interested in testing this in aqua species

Back after coffee at #ISGAXV and another talk on feed efficiency, by Prof Peng Xu from Xiamen University. Using feeding stations inspired by the dry livestock world they developed an automatic real time model to measure individual feed intake in tanks and managed to improve FCR 🧬🖥️🐟

The final talk at #ISGAXV before the coffee break was about rocks, oh no sorry, oysters! Rodrigo Marín-Nahuelpi on assessing the genetic architecture and GS for growth related traits in eastern oyster 🦪 (C. virginica)
A frist study in this population from Canada.

And they got an even better improvement when they used a validation population that was genetically distinct from the training population (+26%)! Very promising results as predictions accuracies are usually low when training and validation pop are distant ...
#ISGAXV

Now at #ISGAXV it's the Genomic selection section, with a first talk from @marc-vdp-inrae.bsky.social presenting their results of selecting for feed efficiency in European sea bass. Starting with the individual recording of FCR and DGC in their cool "single fish per aquarium" system in Palavas

Good morning from Cadiz and from the #ISGAXV
The conference started yesterday with a nice reception and it's great to see so many familiar faces and catch up with friends!
Today is the first day of the official business: talking about aquaculture, genetics and genomics

I've just checked the programme of a symposium that I am attending in 2 weeks #ISGAXV. As usual with ISGA, the talks are super promissing with really good speakers and I'm expecting high quality presentations!
HOWEVER (and that is a big however) we are a long long way from gender balance... 🙄
