Dietary transfer of enriched stable isotopes to mark otoliths, fin rays, and scales
Artificial chemical marking of calcified structures, such as otoliths, has emerged as a powerful method to assess stocking success and determine connectivity patterns in freshwater and marine systems. Although transgenerational and larval immersion methods have been validated, dietary transmission o...
