Christos Palaiokostas
Associate Professor in Aquaculture Breeding - Genetics


My research is focused on aquaculture breeding programs with particular emphasis on the application of high-throughput sequencing technologies for studying complex traits.


I teach on various courses, mainly on the subject of selective breeding and applications of high-throughput sequencing technologies in aquaculture species.

I am a course leader in the course on sustainable aquaculture:


In addition, I am a course leader in an introductory course on Python for data science:



My current research involves the incorporation of high-throughput sequencing technologies in the ongoing national Swedish breeding programs of Arctic charr and rainbow trout (VBCN), aiming at increasing selection accuracies of complex traits.

In my previous post at the Roslin Institute I participated at the FISHBOOST project  (2015 - 2018), aiming to improving genetic resistance of farmed fish against commonly encountered diseases using high-throughput sequencing technologies.

Research projects

- Principal Investigator in the FORMAS funded project NextGenCharr

High-throughput sequencing applications in the Swedish selectively bred strain of Arctic charr

- Work package leader in a Kolarctic funded project



During my current and previous academic posts I have always had close collaboration with associations of aquaculture producers. In particular, I have collaborated with the French aquaculture association SYSSAF in a project aiming to investigate the potential of breeding European sea bass resistant to viral nervous necrosis. Furthermore, during my current post at SLU I have close collaboration with Vattenbrukscentrum Norr where the national Swedish breeding programs are located.
