Stock Discrimination of Gilthead Seabream (Sparus aurata Linnaeus, 1758) through the Examination of Otolith Morphology and Genetic Structure [PDF]

open access: goldFishes, 2023
Reliable stock identification constitutes an integral component of effective fishery management. Current methods for the identification of putative stock units comprise the analysis of both phenotypic and genetic variability.

Stock discrimination of two insular populations of Diplodus annularis (Actinopterygii: Perciformes: Sparidae) along the coast of Tunisia by analysis of otolith shape [PDF]

open access: goldActa Ichthyologica et Piscatoria, 2015
Background. The annular seabream, Diplodus annularis (Linnaeus, 1758), is the most common sparid fish in the Mediterranean Sea. This species is widespread in Tunisia.

Application of Shape Analyses to Recording Structures of Marine Organisms for Stock Discrimination and Taxonomic Purposes [PDF]

open access: goldFrontiers in Marine Science, 2021
Morphometric analysis of biogenic recording structures within marine organisms has applications in stock assessment, taxonomics, and ecomorphological studies, with shape variation markedly influenced by both genetics and the surrounding environment ...

Otolith morphology as a tool for stock discrimination of three rockfish species in the East Sea of Korea [PDF]

open access: goldFrontiers in Marine Science, 2023
The shape and structure of otoliths play a vital role in studying fish populations because otolith shape indices are often applied to discriminate fish species.

Stock discrimination of Sperata aor from river Ganga using microsatellite markers: implications for conservation and management [PDF]

open access: bronzeAquatic Living Resources, 2017
High genetic variation is an important requirement for long term survival of wild populations through adaptations to changing environmental conditions. High levels of variability and the potential to isolate large number of loci make microsatellites the ...

Otolith chemical composition as a useful tool for sciaenid stock discrimination in the south-western Atlantic

open access: diamondScientia Marina, 2006
Striped weakfish (Cynoscion guatucupa) and whitemouth croaker (Micropogonias furnieri) are important commercial and recreational species found in abundance along the South American Atlantic coast.

Pitfalls in stock discrimination by shape analysis of otolith contours [PDF]

open access: bronzeICES Journal of Marine Science, 2015
Abstract This paper focuses on artefacts that may corrupt stock discrimination by shape analysis of otolith contours, how one can examine if such artefacts are important, and how they can be avoided. The scope focuses on Fourier transforms of contour points, the linear Fisher discrimination technique, and success rates based on cross ...

Stock Discrimination of Capelin (Mallotus villosus) in the Northwest Atlantic

open access: bronzeJournal of Northwest Atlantic Fishery Science, 1984
Although capelin is an important commercial and forage species of the Newfoundland region, firm evidence for the designation of separate stocks does not exist. In a previous analysis of meristic characters of capelin, the authors assumed that meristic data were multivariate normal, an assumption that is not usually met.
