Unusual development of an accessory otolith in herring (Clupea harengus) larva

Fisheries & Aquatic Life
Otoliths are key to reconstructing fish life history, as their structure records individual and environmental information. These inner ear structures grow incrementally, revealing growth rates, migration patterns, and environmental conditions.

Shape Analysis of Otoliths of the Round goby, Neogobius melanostomus (Gobiiformes, Gobiidae), from the Black Sea Basin

Zoodiversity, 2021
This study aims to assess the round goby Neogobius melanostomus stocks discriminability based on the shape of its otoliths. Recent otolith-shape-based species and stock discrimination studies have been using otoliths’ contours in sagittal plane and we ...

Sagittal Otoliths of fish in West Indies (Carribean sea) [PDF]

Ce poster présente les otolithes des principales espèces démersales exploitées autour des îles de Martinique et de Guadeloupe. Ces pièces calcifiées de l’oreille interne des poissons permettent d’estimer leur âge et fournissent aussi d'autres informations biologiques.

The role of environmental and life history traits in larval growth and settlement success of the blenny Ophioblennius trinitatis

Limnology and Oceanography Letters, Volume 11, Issue 4, July 2026.
Abstract Reef fish have complex life cycles where pelagic larval survival and recruitment are linked to environmental and early life history traits (ELHTs). We combine light traps and otolith microstructure analysis to examine how environmental variables and ELHTs drive larval growth and settlement in the endemic Ophioblennius trinitatis.

A Unique and Species-Rich Assemblage of Freshwater Glassfishes (Teleostei: Ambassidae: Dapalis) from the lower Oligocene of the Central Paratethys with the Description of Four New Species

Taxonomy
We describe four new species of the fossil genus Dapalis (Ambassidae), Dapalis absconditus sp. nov., Dapalis octospinus sp. nov., Dapalis parvus sp. nov. and Dapalis quintus sp. nov., based on articulated skeletons with otoliths in situ from a freshwater

Larval development and growth of the European hake Merluccius merluccius in the northwestern Mediterranean

Scientia Marina, 2005
The larval growth and development of the European hake, Merluccius merluccius, was studied from field larvae. Larvae were collected in the northwestern Mediterranean on three cruises carried out during the peak spawning months (November 1998, September ...

Age and Growth of the Silver Scabbardfish, Lepidopus caudatus (Euphrasen, 1788), in the Eastern Adriatic

Fishes
The age, growth and otolith morphometry of Lepidopus caudatus were studied by investigating the sagittal otoliths of specimens collected in the eastern Adriatic. A total of 295 specimens, ranging from 20.7 to 123.0 cm in total length (TL), were analysed.

Otolith Image-Based Age Classification of Japanese Jack Mackerel Trachurus japonicus Using Convolutional Neural Networks

Journal of Marine Science and Engineering
Reliable age information is needed for fisheries assessment, but conventional otolith reading requires trained readers and considerable time. This study evaluated whether convolutional neural networks could classify reader-assigned age classes of ...
