Shedding light on the parasite communities and diet of the deep‐sea shark Deania profundorum (Smith & Radcliffe, 1912) (Squaliform: Centrophoridae) from the Avilés Canyon (southern Bay of Biscay)

Journal of Fish Biology, EarlyView.
Abstract Deep‐sea elasmobranchs are less resilient to the increasing scale of anthropogenic impacts such as fisheries, owing to their life‐history traits. The necessity for proper management measures is hampered by the scant knowledge on these taxa and their biology. Here we provide the first comprehensive insight into the parasite infracommunities and

Return migration to fresh water and overwintering locations used by sympatric anadromous populations of Arctic char (Salvelinus alpinus) and Dolly Varden (Salvelinus malma malma)

Journal of Fish Biology, EarlyView.
Abstract Anadromous Arctic char (Salvelinus alpinus) and northern form Dolly Varden (Salvelinus malma malma) are highly valued by Indigenous communities in northern Canada. Rapid, ongoing environmental changes are affecting populations of both of these iteroparous species, and understanding variability in life‐history tactics is essential for ...

Does any fish scale of a fish have the same number of marks? A case study for two Mugilidae species

Journal of Fish Biology, EarlyView.
Abstract This study evaluates the difference in growth marks in scales from nine body areas of two Mugilidae species from the Gulf of Mexico: Mugil curema and Mugil cephalus. It addresses whether the different body areas show more (or fewer) marks, and which area(s) would be more useful in fish biology studies relying on mark analysis.

Phenotypic divergence may facilitate co‐occurrence in Acanthopagrus species (Family: Sparidae)

Journal of Fish Biology, EarlyView.
Abstract Understanding why closely related species co‐occur is one fundamental question in ecology. The seabream genus Acanthopagrus Peters, 1855 (Sparidae) is broadly distributed across the Indo‐Pacific, with four species, A. arabicus and A. sheim (yellowfin group), and A. bifasciatus and A.

Contrasting life‐history strategies of three sympatric icefish species in the northern Scotia Sea

Journal of Fish Biology, EarlyView.
Abstract Comprehending a species' life‐history strategies is crucial to inform effective conservation efforts. Commercial fishing impacts icefish (family: Channichthyidae) in the Scotia Sea, but detailed information on species‐specific life histories remains largely unknown.

Assessment of two minimally invasive methodologies for sex identification in the European eel, Anguilla anguilla

Journal of Fish Biology, EarlyView.
Abstract Sex is an important driver of variation in behaviour, ecology and physiology. Sex identification in the Critically Endangered European eel (Anguilla anguilla) currently requires fish sacrifice, or the use of morphological differences such as body length, which can be inaccurate in certain habitats and at intermediate body lengths.

Otolith shape analyses and dimensions of the Anchovy Engraulis encrasicolus L. in the Black and Marmara Seas

, 2015
Otoliths, which can be used for the evaluation of relationships between the environment and organisms, are structures consisting of calcium carbonate. The aim of this study was to realize the shape analysis.

Beyond spring season: An autumn observation of adult lumpsuckers (Cyclopterus lumpus) in coastal Norway Frøya archipelago raises questions on extended spawning activity

Journal of Fish Biology, EarlyView.
Abstract During snorkelling near Frøya, central Norway, on 6 October 2025, a pair of adult lumpsuckers (Cyclopterus lumpus) was observed engaged in apparent prespawning behaviour in shallow kelp habitat. Such activity is surprising, as the species is mainly considered a spring spawner throughout the eastern Atlantic and is the focus of a targeted ...

Intra‐annual energy density cycles of spring‐ and fall‐spawning Atlantic herring Clupea harengus reveal different reproductive allocation tactics

Journal of Fish Biology, EarlyView.
Abstract Atlantic herring Clupea harengus are total spawners that exhibit a large degree of reproductive plasticity and have substantial intra‐annual variation in their energetic condition. Recent research suggests that the species may be declining in energetic condition in the northwest Atlantic Ocean from the few historical records, but comparisons ...
