The dataset reported here corresponds to the experimental study aiming at evaluating the impact of whole-life acclimation to different degrees of ocean pH/pCO2 (current condition of the Rade de Brest and predictions of RCP8.5 IPCC scenario by 2050 and by 2100) on the sexual maturation and spawning of a temperate marine teleost, the European sea bass (Dicentrarchus labrax), over two consecutive reproductive cycles. The hypothesis that severe acidification would lead to the highest impact on plasma sex steroids concentrations and on spawning phenology driving to higher female fecundity was tested. The same physiological traits were monitored during the two first reproductive seasons to estimate the acclimation potential at longer exposition, in pubertal and post-pubertal fish. In all data sheets, “ID” indicates the identification number of fish and “scenario” the corresponding acidification level. The dataset contains: - Fulton’s condition factor (K) of females and males in both reproductive seasons ...
