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.13 p.application/pdfengcc by (c) Coll-Lladó, Clara et al., 2021http://creativecommons.org/licenses/by/3.0/es/CalcitaGènereOtòlitsCalciteGenderOtolithsinfo:eu-repo/semantics/article7208832022-05-11info:eu-repo/semantics/openAccess
