Stock delineation of striped snakehead, Channa striata using multivariate generalised linear models with otolith shape and chemistry data [PDF]
Scientific Reports, 2021 Otoliths are commonly used to discriminate between fish stocks, through both elemental composition and otolith shape. Typical studies also have a large number of elemental compositions and shape measures relative to the number of otolith samples, with ...

Phenotypic variation in otolith shape of American shad across eastern North American rivers [PDF]
Scientific ReportsOtolith shape analysis has been widely applied to study population structure and environmental influences in various fish species. However, research on American shad (Alosa sapidissima) otolith morphology remains scarce, despite its potential to provide ...

Complementarity and discriminatory power of genotype and otolith shape in describing the fine-scale population structure of an exploited fish, the common sole of the Eastern English Channel. [PDF]
PLoS ONE, 2020 Marine organisms show population structure at a relatively fine spatial scale, even in open habitats. The tools commonly used to assess subtle patterns of connectivity have diverse levels of resolution and can complement each other to inform on ...

Latitudinal Gradient in Otolith Shape among Local Populations of Atlantic Herring (Clupea harengus L.) in Norway. [PDF]
PLoS ONE, 2015 Otolith shape analysis of Atlantic herring (Clupea harengus) in Norwegian waters shows significant differentiation among fjords and a latitudinal gradient along the coast where neighbouring populations are more similar to each other than to those sampled

Otolith shape variability and associated body growth differences in giant grenadier, Albatrossia pectoralis. [PDF]
PLoS ONE, 2017 Fish stocks can be defined by differences in their distribution, life history, and genetics. Managing fish based on stock structure is integral to successful management of a species because fishing may affect stocks disproportionately.

Using otoliths for fish stock discrimination: status and challenges [PDF]
Acta Ichthyologica et Piscatoria, 2021 Otoliths are calcified structures and the information contained within their chemistry or shape can be used to infer life history events, migration patterns, and stock structure of a fish population.
