    To find a thermal mark on an otolith, fish must be sampled, then their sagittae otoliths (the largest of the 3 pairs) are removed. The left sagittae otolith is glued to a glass slide with thermoplastic cement then ground on a grinder. When the center of the otolith is reached, it is examined under a microscope for the presence of a thermal mark.

    Otolith microchemical analysis - Wikipedia. Otolith microchemical analysis is a technique used in fisheries management and fisheries biology to delineate stocks and characterize movements, and natal origin of fish.The concentrations of elements and isotopes in otoliths are compared to those in the water in which the fish inhabits in order to identify where it has been.

  • Comparison of otolith growth and somatic growth in

    Although it has been argued that otolith size is highly correlated with fish size, since they are both controlled by the same metabolic processes (Boehlert, 1985), experimental studies using fish of known age (Reznick et al., 1989; Secor and Dean, 1989) have shown that for juveniles the relationship between otolith size and fish size is ...

    As such, otolith weight may also provide an index for fish age (Lou et al., 2007). However, the rate of change for otolith weight is dependent upon the growth rate (Pawson, 1990) and habitat (Metin and Ilkyaz, 2008), so aging fish based solely on otolith weight is likely to be problematic. Here we found that otolith weight had a positive and ...
