Environmental effects on otolith morphology variability of European eel, Anguilla anguilla (Linnaeus, 1758), for subpopulation discrimination in Corsica

open access: yesFrontiers in Marine Science
Otolith shape analysis is an efficient tool for fish stock identification. However, due to insufficient research, it remains still poorly understood concerning the European eel (Anguilla anguilla), a highly migratory catadromous and panmictic species ...

Stock Status of Ompok bimaculatus in Kaptai Lake: A Length‐Based Approach for Sustainable Fisheries Management

open access: yesAquaculture, Fish and Fisheries, Volume 6, Issue 5, October 2026.
ABSTRACT Ompok bimaculatus, a silurid catfish, is a commercially valuable and endangered species in Bangladesh. Kaptai Lake is a critical habitat for this species, yet growing market demand and ecological pressures jeopardize stock sustainability. Therefore, this study employed a length‐based approach integrating LB‐SPR and aLBI to conduct the baseline

Periodicity of otolith check formation in the juvenile plaice Pleuronectes platessa [PDF]

open access: yes, 1995
Juvenile (Pleuronectes platessa L.) were sampled in the intertidal zone of Port Erin Bay (Isle of Man, Irish Sea) by push-net in the summers of 1990 and 1992.

Otoliths in situ in Pinichthys shirvanensis Bannikov, 2021 (Stromateidae) from the Tarkhanian (Langhian, Middle Miocene) of the northern Caucasus (Russia)

open access: yesSwiss Journal of Palaeontology
Otolith finds in situ are important for connecting the independent data sets of articulated fish skeletons and isolated otoliths in the fossil record. Here we describe an otolith in situ retrieved from a skeleton of the stromateid Pinichthys shirvanensis

Differences in sagittal otoliths between two morid species: insights into the genus Physiculus (Moridae: Gadiformes)

open access: yesNeotropical Ichthyology
Sagittae are widely used as tools in taxonomic and ecological studies of fishes, especially when external morphological characters are conserved or ambiguous. We analyzed morphological variation between two congeneric species of Physiculus: P.

Tapeworm Parasite Burden Is Linked to Diet, Body Size, Condition, Growth, Restocking and Habitat Use in Piscivorous Salmonids of a Subarctic Lake

open access: yesEcology of Freshwater Fish, Volume 35, Issue 4, October 2026.
ABSTRACT Parasites affect hosts in interaction with the entire ecological community. This is particularly evident for trophically transmitted parasites, such as Dibothriocephalus tapeworms, which infect multiple intermediate fish hosts, potentially reducing their fitness and suitability for human consumption.

The Effect of Temperature, Flow, Density and Disease on Smallmouth Bass (Micropterus dolomieu) Early Life Growth Rate

open access: yesEcology of Freshwater Fish, Volume 35, Issue 4, October 2026.
ABSTRACT Individual growth rates of fish are influenced by gradually changing environmental conditions and rapid‐onset events. However, there is a paucity of information on drivers of spatiotemporal variability in growth rates of fishes across large spatial extents.

Migratory behaviour and otolith chemistry suggest fine-scale sub-population structure within a genetically homogenous Atlantic Cod population

open access: yes, 2010
The question whether temperate marine fishes typically consist of self-sustaining populations or "open" populations still remains unresolved. At the heart of this population connectivity problem lays the nature of the stock separation mechanisms.

Epigenetic Clocks Can Predict Age in the Largemouth Bass‐Complex Despite Spatial and Sexual Variation

open access: yesEvolutionary Applications, Volume 19, Issue 10, October 2026.
ABSTRACT Sustainable fisheries rely on balancing harvests with ecological impacts. Despite the importance of species' demographic profiles, many assessments forgo age due to methodological complexities. Developing non‐lethal methods for age determination can improve stock assessments to ensure future sustainability. Epigenetic signals, specifically DNA
