Water and Otolith Chemistry: Implications for Discerning Estuarine Nursery Habitat Use of a Juvenile Flatfish

Frontiers in Marine Science, 2020
Variations in otolith elemental composition are widely used to reconstruct fish movements. However, reconstructing habitat use and environmental histories of fishes within estuaries is still a major challenge due to the dynamic nature of these coastal ...

Morphology of sagitta, lapillus and asteriscus of Patagonian Genidens barbus

Marine and Fishery Sciences, 2022
Otoliths are calcium carbonate structures, deposited as aragonite, located in the inner ear of bony fish. In recent years, they have become a useful tool for the determination of fish species, trophic content, age studies, and the identification of fish

Relationship between fish size and otolith length for 63 species of fishes from the Eastern North Pacific Ocean [PDF]

, 2000
Otoliths commonly are used to determine the taxon, age, and size of fishes. This information is useful for population management, predator-prey studies, and archaeological research.

Using Eye Lens Stable Isotopes to Identify the Rearing Origin of Fall Age‐0 Walleye (Sander vitreus)

Fisheries Management and Ecology, EarlyView.
ABSTRACT Isotope values in fish eye lenses may be useful in differentiating rearing origins. We compared eye lens isotopic values of fall fingerling age‐0 walleye (Sander vitreus) reared in a hatchery pond, a recirculating aquaculture system (RAS), and a natural lake. Using 10 fish per rearing source, we delaminated layers from one eye lens per fish to

A Case Study of Coilia nasus: Is There a Difference in Microchemical Signatures Between Left and Right Fish Sagittae?

Fishes
Owing to the asynchronous deposition of trace elements between paired left and right otoliths within individual fish, researchers must consciously and uniformly use only single otoliths (especially the left one) for microchemical studies.

Stomach contents of cetaceans in the Alboran Sea and Gulf of Cadiz.

Frontiers in Marine Science, 2014
This work describes the diet, through the analysis of stomach contents, of different species of cetaceans in Andalusian waters. Stomachs of 53 specimens, 36 striped dolphins (Stenella coeruleoalba), 13 common dolphins (Delphinus delphis) and 4 Risso's ...

Validation of daily growth increments and estimation of growth rates of larval and early juvenile black skipjack, Euthynnus lineatus, using otoliths [PDF]

, 1993
ENGLISH: Increments in otoliths (sagittae) were examined, using light and scanning electron microscopy, to determine ages and estimate growth rates of larval and early-juvenile black skipjack, Euthynnus lineatus.

Disentangling the Drivers of a Piscivorous Intra‐Annual Cohort and the Contributions of Three Cohorts to Early‐Year Class Strength in Pikeperch (Sander lucioperca)

Fisheries Management and Ecology, EarlyView.
ABSTRACT Using pikeperch (Sander lucioperca) as a model species, we investigated the factors influencing fluctuations in the abundance of piscivorous intra‐annual cohorts and assessed the role of three distinct cohorts: extremely small (ES), ordinary (or mid‐sized) fingerlings, and piscivorous in shaping year‐class strength.

OTOLITH MORPHOLOGY OF SOME FRESHWATER FISHES OF IRAN

‬‭Majallah-i ̒Ilmī-i Shīlāt-i Īrān, 2008
Otoliths or ear stones are small white bodies present in the ear of bony fishes. Otoliths are important in keeping fish position and steadiness and also are useful structures in hearing.

First evidence of otolith abnormalities in Belone belone from the Sea of Marmara: An integrative approach to morphological deformities with light and scanning electron microscopy

Oceanological and Hydrobiological Studies
This study is the first of its kind, providing detailed evidence of otolith abnormalities in Belone belone in the Darıca coast of the Sea of Marmara (Türkiye), using an integrative approach that combines light microscopy and scanning electron microscopy (
