WebOtolith microstructure has been demonstrated to be a potentially useful tool for investigating early survivorship in fishes, since otoliths may provide a chronological record of early growth and life-history events (see Campana & Neilson, 1985).

WebOtolith microchemistry was applied to quantify migratory variation and the proportion of native Caribbean stream fishes that undergo full or partial marine migration. Strontium and barium water chemistry in four Puerto Rico, U.S.A., rivers was clearly related to a salinity gradient; however, variation in water barium, and thus fish otoliths, was also dependent on … WebWhen the otolith was viewed using fluorescence microscopy, a glowing band appeared that corresponded to the injection of OTC. The number of annuli between the OTC band and the edge of the otolith was also seven, thus linking a single annulus to one year of growth (Taylor et al., 2000). However, such information relies heavily on time and chance.
