Seasonal Temperature Differentially Modulates the Immunotranscriptomic Performance in Atlantic Salmon Skin in Response to Natural Infestation in Open-Ocean Cages.

Chile is the second-largest producer of Atlantic salmon (), a key industry facing challenges such as infestations by , which cause significant economic losses. However, there are no studies exploring how environmental variables in marine culture centers affect salmon's immune response, considering their poikilothermic characteristics. This study analyzed the effect of the seasonal temperature on the skin transcriptome of Atlantic salmon infested with in fjord-based farms in the Aysén Region during autumn and spring.
