Pilot study to investigate the effect of long-term exposure to high pCO2 on adult cod (Gadus morhua) otolith morphology and calcium carbonate deposition Coll-Lladó, Clara Mittermayer, Felix Webb, Paul Brian Allison, Nicola Clemmesen, Catriona Stiasny, Martina Bridges, Christopher Robert Göttler, Gwendolin García de la Serrana Castillo, Daniel Calcita Gènere Otòlits Calcite Gender Otoliths 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. 2022-05-11T12:45:46Z 2022-05-11T12:45:46Z 2021-09-28 2022-05-11T12:45:46Z info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion 0920-1742 https://hdl.handle.net/2445/185553 720883 eng Reproducció del document publicat a: https://doi.org/10.1007/s10695-021-01016-6 Fish Physiology and Biochemistry, 2021, vol. 47, num. 6, p. 1879-1891 https://doi.org/10.1007/s10695-021-01016-6 cc by (c) Coll-Lladó, Clara et al., 2021 http://creativecommons.org/licenses/by/3.0/es/ info:eu-repo/semantics/openAccess 13 p. application/pdf Springer Verlag Articles publicats en revistes (Biologia Cel·lular, Fisiologia i Immunologia)
