Microchemical Analyses of Otoliths Reveal Habitat Differentiation Between a Sympatric Species Pair in the Coastal Waters of China [PDF]

Ecology and Evolution
While secondary contact between distant lineages or sister species is a common evolutionary outcome, the factors that promote their coexistence are often unknown, especially for marine species. Focusing on two sister fish species from the East China Sea,

Spatiotemporal Variability of Trace Elements Fingerprints in Otoliths of Japanese Eel (Anguilla japonica) and Its Use in Tracing Geographic Origin [PDF]

Biology, 2022
To secure traceability along supply chains of foodstuffs, the spatiotemporal variability of trace elements’ fingerprints (TEF) in fish otoliths provides a powerful tool to determine and discriminate the origin.

A Bayesian classification model to reconstruct lifetime movement patterns of riverine fish using environmental tracers

Methods in Ecology and Evolution
Environmental tracers, including both elemental concentrations and isotope ratios, are widely used to reconstruct the movement patterns of animals throughout landscapes.

Migratory Ecology of Pseudoplatystoma fasciatum in the Amazon Basin Revealed by Otolith Microchemistry [PDF]

Diversity
Fish migrate for varied reasons, including to avoid predators and to access feeding, spawning, and nursery habitats, behaviors that enhance their survival and reproductive rates.

Otolith chemical fingerprints of skipjack tuna (Katsuwonus pelamis) in the Indian Ocean: First insights into stock structure delineation.

PLoS ONE, 2021
The chemical composition of otoliths (earbones) can provide valuable information about stock structure and connectivity patterns among marine fish. For that, chemical signatures must be sufficiently distinct to allow accurate classification of an unknown

An Epigenetic Clock for Accurate Age Prediction in Atlantic Cod Populations for Improved Fisheries Management. [PDF]

Mol Ecol Resour
ABSTRACT Fisheries management relies on accurate stock assessments, which in turn depend on precise age information. Recent molecular tools called ‘epigenetic clocks’ harness age‐related DNA methylation changes to build accurate and precise age‐prediction models.

Life history of spinyhead croaker Collichthys lucidus (Sciaenidae) differentiated among populations from Chinese coastal waters

Aquatic Biology, 2022
Otolith microchemistry provides valuable information about the environmental history of individual fish, but few studies have considered the influence of population or stock on life history traits.

Distinct Stocks of the Redtail Scad Decapterus kurroides Bleeker, 1855 (Perciformes: Carangidae) from the Northern Sulu and Southern Sibuyan Seas, Philippines Revealed from Otolith Morphometry and Shape Analysis

Fishes, 2022
A recent study was performed to assess the morphometric variation of otoliths of the Decapterus kurroides collected in the northern Sulu and southern Sibuyan seas in delineating fish stocks.

Quantifying physiological influences on otolith microchemistry [PDF]

Methods in Ecology and Evolution, 2015
Summary Trace element concentrations in fish earstones (‘otoliths’) are widely used to discriminate spatially discrete populations or individuals of marine fish, based on a commonly held assumption that physiological influences on otolith composition are minor, and thus variations in otolith elemental chemistry primarily reflect changes in ambient ...
