Identification of Fishes by their Otoliths in 3D, English Channel and North Sea

3D Fish Otolith Identification: English Channel and North Sea

This practical guide by Mahé Kélig, Aurélie Matéos, and their co-authors explores the identification of fish species through three-dimensional analysis of otoliths, the calcified structures found in the inner ear. Focusing on commercial fish from the English Channel and North Sea, it uses X-ray microtomography to describe otolith shapes and characteristics. The book supports fish identification, population differentiation, geographical analysis, and fisheries research.
