Otolith development and elemental incorporation in response to seawater acidification in the flounder Paralichthys olivaceus at early life stages
Ocean acidification can influence the formation, development and functions of calcified structures in marine organisms, such as otoliths, which are mainly composed of calcium carbonate (CaCO3) and function in orientation, balance, sensory perception and locomotion in fish. This study investigated th...
