| Summary: | The environment gametes perform in just before fertilisation is increasingly recognised to affect offspring fitness, yet the contributions of male and female gametes and their adaptive significance remain largely unexplored. Here, we investigated gametic thermal plasticity and its effects on hatching success and embryo performance in Atlantic salmon (Salmo salar). Eggs and sperm were incubated overnight at 2°C or 8°C, temperatures within the optimal thermal range of this species. Crosses between warm- and cold-incubated gametes were compared using a fully-factorial design, with half of each clutch reared in cold temperatures and the other in warm temperatures. This allowed disentangling single-sex interaction effects when pre-fertilisation temperature of gametes mismatched embryonic conditions. Pre-fertilisation temperature influenced the age at hatch, and matching sperm and embryo temperatures resulted in earlier hatching. Warm incubation benefited eggs but harmed sperm, reducing the hatching success and, ... : # Data set associated to the research article 'Pre-fertilisation gamete thermal environment influences offspring fitness, unmasking opposing sex-specific responses in Atlantic Salmon #All the material has been deposited on the DRYAD repository for replicability, transparency and for future research purposes. #List of necessary files: Thermal\_switch\_R\_NEWtime01.xlsx Thermal\_switch\_R\_single\_MAY.xlsx Thermalfrypertotmean\_1.xlsx Thermalsingle.xlsx Thermalsingle1.xlsx Thermalsinglefin.xlsx #files containing the collected parameters and variables used in the models.
