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

Oceans, 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 ...

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

Integrated 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

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

Fishes, 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 ...

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

Marine 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

Disentangling fluctuating asymmetry from otolith shape [PDF]

Marine 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.

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

E3S 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 ...

Otolith shape lends support to the sensory drive hypothesis in rockfishes [PDF]

Journal of Evolutionary Biology, 2016
AbstractThe sensory drive hypothesis proposes that environmental factors affect both signalling dynamics and the evolution of signals and receivers. Sound detection and equilibrium in marine fishes are senses dependent on thesagittaeotoliths, whose morphological variability appears intrinsically linked to the environment.

Shapes of otoliths in some Baltic fish and their proportions

Oceanological and Hydrobiological Studies, 2019
Abstract Otoliths are bony structures inside the fish labyrinth. They are used to determine the age of fish and to identify species based on their remains. The objective of this study was to describe the shape of otoliths in adult European perch (Perca fluviatilis), Atlantic herring (Clupea harengus), European sprat (Sprattus sprattus ...
