Journal ArticleDOI
Otolith chemistry does not just reflect environmental conditions: a meta-analytic evaluation
TL;DR: In this paper, a meta-analysis confirmed a correlation between concentrations of Sr:Ca and Ba:Ca in otoliths and the surrounding water, both elements displaying positive otolith-water correlations.
Journal ArticleDOI
Partial migration: growth varies between resident and migratory fish.
TL;DR: Otolith chemistry data is used to determine whether fish from a large estuarine system were resident or migratory, and whether contingents display differences in modelled growth based on changes in width of otolith growth increments, to suggest management of species exhibiting partial migration is challenging.
Journal ArticleDOI
Strontium randomly substituting for calcium in fish otolith aragonite.
TL;DR: X-ray absorption spectroscopy results consistently indicated that Sr randomly replaces Ca within the aragonite lattice of otoliths, validating a fundamental and long-held assumption in aquatic research.
Journal ArticleDOI
Fish as proxies of ecological and environmental change

TL;DR: Temporal data sourced from fish can improve understanding of how aquatic ecosystems have changed, particularly when multiple sources of data are used, enhancing the ability to interpret the current state of aquatic ecosystems and establish effective measures to safeguard against further adverse shifts.
Journal ArticleDOI
Relative contribution of water and diet to otolith chemistry in freshwater fish
TL;DR: In this article, the authors tested the proportional contributions of water and diet in 3 Australian freshwater fish (silver perch, golden perch and Murray cod) in a controlled laboratory experiment and found that water was the dominant source of elements in the otoliths, contributing between 64 and 71% for Sr and 88 and 92% for Ba.
