Seawater carbonate chemistry and growth and reproduction of three-spined Stickleback (Gasterosteus aculeatus)

We investigated the joint effect of warming and acidification on three-spined stickleback (Gasterosteus aculeatus) from the juvenile stage to adulthood, focusing on parameters linked to growth, sexual maturation, and reproduction. Juvenile sticklebacks were split in 2 climate scenarios: a "Current" scenario corresponding to the current seasonal physico-chemical parameters of the water of the "Rade de Brest" in France, and a "RCP8.5" scenario with a warming of 3 °C and an acidification of 0.4 pH units.
