The use of otolith shape to identify stocks of Konosirus punctatus [PDF]

Israeli Journal of Aquaculture - Bamidgeh, 2020
Konosirus punctatus is an important economic fish in the Northwest Pacific Ocean, especially along the coast of China, and an important substitute in the marine ecosystem. The aim of this study is to quantify the variation of sagittal shapes to discriminate the K.

Otolith shape discrimination of Liza ramada (Actinopterygii: Mugiliformes: Mugilidae) from marine and estuarine populations in Tunisia [PDF]

Acta Ichthyologica et Piscatoria, 2017
Background. The thinlip grey mullet, Liza ramada (Risso, 1810), is widespread in Tunisia. Despite its economic importance, the stock discrimination of this fish is poorly understood.

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

ICES 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 ...

Assessing the Speciation of Lutjanus campechanus and Lutjanus purpureus through Otolith Shape and Genetic Analyses

Fishes, 2022
Based on their morphological and genetic similarity, several studies have proposed that Lutjanus campechanus and Lutjanus purpureus are the same species, but there is no confirmed consensus yet.

Otolith Morphometric and Shape Distinction of Three Redfin Species under the Genus Decapterus (Teleostei: Carangidae) from Sulu Sea, Philippines

Fishes, 2023
Otoliths are paired calcified structures in the inner ear of teleosts that function in hearing and balance. In this study, the use of otolith morphometrics and shape analysis were explored to delineate the redfin species under the genus Decapterus from ...

Developmental Temperature Shapes the Otolith Morphology of Metamorphosing and Juvenile Gilthead Seabream (Sparus aurata Linnaeus, 1758)

Fishes, 2022
Otolith morphological variability is used as a reliable indicator to discriminate fish that experience different environmental conditions during their lifetimes.

Ontogenetic and sexual variation in the sagitta otolith of Menticirrhus americanus (Teleostei; Sciaenidae) (Linnaeus, 1758) in a subtropical environment [PDF]

Papéis Avulsos de Zoologia, 2020
This study aimed to verify variations in the form of the sagitta otolith of Menticirrhus americanus as to their ontogeny, sex and stage of such structure. Ontogenetically were found significant differences (p < 0.05) for all shape indices (aspect ratios,

Relationships between Fish Sizes and Otolith Sizes of Whiting (Merlangius merlangus Linnaeus, 1758) from the Western Black Sea

Aquatic Sciences and Engineering, 2020
The objective of this study was to determine the regressions between otolith sizes and shape indices vs. fish length, and weight of whiting, Merlangius merlangus (Linnaeus, 1758), from the Black Sea. Samples were collected randomly from commercial bottom

Potential directional asymmetry of the otolith shape tested on the red mullet (Mullus barbatus) in the Mediterranean Sea: comparative analysis of 2D and 3D otolith shape data [PDF]

, 2022
A wide number of techniques were developed and applied to identify and discriminate stocks. Among them, otolith’s shape, which is affected by environment and genetic factors, can be used as a tool to identify the populations within the species. Before to identify the boundaries of stocks, the potential drivers, which control the otolith shape, must be ...

Identification of gerreid species (Actinopterygii: Perciformes: Gerreidae) from the Pacific coast of Mexico based on sagittal otolith morphology analysis [PDF]

Acta Ichthyologica et Piscatoria, 2012
Background. Although the species of the family Gerreidae have been subjected to many studies, their taxonomy at specific- and sometimes generic levels is still confusing. To contribute to the clarification of the taxonomy of the Mexican Pacific mojarras,
