Geometric Analysis of Luciobarbus barbulus (Heckel 1847) Otoliths With Body Shape [PDF]
Background The Cyprinidae family is one of the most varied families in terms of number of species, representing approximately 1500 species in the world. Luciobarbus barbulus (Heckel 1847) is a little‐known species, but it is widespread in the Tigris and ...

Otolith shape variability and associated body growth differences in giant grenadier, Albatrossia pectoralis. [PDF]
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.

Stock delineation of striped snakehead, Channa striata using multivariate generalised linear models with otolith shape and chemistry data [PDF]
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 ...

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]
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]
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

Clarifying species identity in Aphanopus using wavelet-based otolith shape analysis. [PDF]
Accurate species identification is crucial for effective fisheries management, particularly for cryptic species with overlapping ranges and similar morphologies. This study explores the coexistence and distribution of Aphanopus carbo and Aphanopus intermedius in the northeastern Atlantic over four decades using otolith contour analysis. Otolith samples

Sex matters: Otolith shape and genomic variation in deacon rockfish (Sebastes diaconus). [PDF]
AbstractLittle is known about intraspecific variation within the deacon rockfish (Sebastes diaconus), a recently described species found in the northeast Pacific Ocean. We investigated population structure among fish sampled from two nearshore reefs (Siletz Reef and Seal Rock) and one offshore site (Stonewall Bank) within a <50‐km2 area off the ...

Phenotypic variation in otolith shape of American shad across eastern North American rivers [PDF]
Otolith 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 ...

Congruent geographic variation in saccular otolith shape across multiple species of African cichlids. [PDF]
AbstractThe otoliths of teleost fishes exhibit a great deal of inter- and intra-species shape variation. The ecomorphology of the saccular otolith is often studied by comparing its shape across species and populations inhabiting a range of environments.
