Integrated use of otolith shape and microchemistry to assess Genidens barbus fish stock structure

European hake (Merluccius merluccius) stock structure in the Mediterranean as assessed by otolith shape and microchemistry

“…More efficient and accurate stock characterization may be obtained from integrated studies of otolith morphometry and chemistry (Biolé et al, 2019;Longmore et al, 2010;Soeth et al, 2019). However, discriminant power will depend not only on the traits used; larger discrimination is expected when shape and/or chemical composition are homogeneous at the within-unit scale but display clear-cut differences at the between-unit scale (Longmore et al, 2010;Rodrigues Maciel et al, 2021).…”
