Resum
To date the study of ocean acidifcation on fsh otolith formation has been mainly focused on larval and juvenile stages. In the present pilot study, wild-captured adult Atlantic cod (Gadus morhua) were exposed to two diferent levels of pCO2, 422µatm (ambient, low pCO2) or 1091µatm (high pCO2), for a period of 30 weeks (from mid-October to early April 2014-2015) in order to study the efects on otolith size, shape and CaCO3 crystallization amongst other biological parameters. We found that otoliths from cod exposed to high pCO2 were slightly smaller (−3.4% in length;−3.3% in perimeter), rounder (−2.9% circularity and+4% roundness) but heavier (+5%) than the low pCO2 group.
