Disentangling fluctuating asymmetry from otolith shape [PDF]

open access: yesMarine Ecology Progress Series, 2010
Fluctuating asymmetry (FA), defined as random deviations from ideal, perfect symmetry, has been hypothesized to be negatively associated with fitness and positively associated with stress. Fish otoliths deserve special attention in regard to this topic because their FA is relatively easy to measure, unlike the fitness of wild fish themselves.

Relationship between Body and Otolith Morphological Characteristics of Sabre Squirrelfish (Sargocentron spiniferum) from the Southern Red Sea: Difference between Right and Left Otoliths

open access: yesOceans, 2021
Otolith morphology analysis is one of the main tools used for fish or fish stock identification. Moreover, otolith shape can also be used in animal dietary studies (stomach content) for the identification of prey fishes and their size according to the ...

Exploring European Eel Anguilla anguilla (L.) Habitat Differences Using Otolith Analysis in Central-Western Mediterranean Rivers and Coastal Lagoons from Sardinia

open access: yesFishes, 2023
An otolith shape and morphometric analysis was performed on European eel (Anguilla anguilla) subpopulations from five rivers and three coastal lagoons of Sardinia (central-western Mediterranean) to assess the role of different habitats on otolith ...

Feeding history influences otolith shape in tropical fish [PDF]

open access: yesMarine Ecology Progress Series, 2004
The influence of feeding history on otolith shape and symmetry was examined in juveniles of 2 species of coral reef fish, Amphiprion akindynos and Pomacentrus amboinensis. Fast Fourier analysis was used to describe the shape of otoliths of fish from a variety of experimental feeding treatments, ranging from starvation, through pulse feeding, to feeding

Otolith shape as a tool for representing different growth in young and adult yellowfin tuna (Thunnus albacares, Bonnaterre, 1788) [PDF]

open access: yesE3S Web of Conferences, 2021
The stock status of yellowfin tuna (Thunnus albacares) (YFT) in the Indian Ocean is currently concluded overfished and is subject to overfishing. The information about the YFT population structure is fundamental for effective fisheries management and ...

Relationships among tissues, biofluids, and otolith selenium concentrations in wild female burbot (Lota lota)

open access: yesIntegrated Environmental Assessment and Management, EarlyView., 2023
Abstract In the Lake Koocanusa‐Kootenai River system (Montana, USA and British Columbia, Canada), selenium (Se) contamination has become an international concern and is suspected to contribute to the observed burbot (Lota lota) population collapse. Due to our limited ability to sample burbot in Lake Koocanusa for monitoring studies, we used a reference

Diet is correlated with otolith shape in marine fish [PDF]

open access: yesMarine Ecology Progress Series, 2016
Previous studies have shown that the amount of food influences fish otolith structure, opacity and shape and that diet composition has an effect on otolith chemical composition. This study investigated the potential correlation between diet and otolith shape in 5 wild marine fish species by addressing 4 complementary questions. First, is there a global

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

open access: yesActa 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.

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

open access: yesFishes, 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.
