Chub

2016-2017. Chub production in controlled environment for studying larval and juvenile development by otolith shape analysis (IRSTEA Aix-en-Provence, CNRS Lyon).Read more...

Otoliths are calcium carbonate accretions located in the internal ear that develop very early during the ontogeny of teleost fishes. Their morphology evolves during life in relation with genetics and environment and is used as a marker to identify populations and their geographic variations. This study, performed by IRSTEA, aimed to analyse chub (Squalius cephalus) otolith evolution during early life stages in a controlled environment.
