Distinct sex differences in the production of steroids and neuropeptides in the adult zebrafish brain–pituitary–gonadal axis

FACETS
Zebrafish are valuable models for studies of human disease, environmental toxicology, and reproductive biology. However, sex differences in hormone production are rarely examined, despite gene mutation studies showing differential effects in females and ...

Expression of corticoid‐regulatory genes in the gills of Atlantic salmon (Salmo salar) parr and smolt and during salinity acclimation

Journal of Fish Biology, EarlyView.
Abstract In teleost fishes, cortisol is the major corticoid and has both glucocorticoid and mineralocorticoid actions. However, how fish tissues discriminate between these distinct corticosteroid actions is unclear. In mammals, the major factors responsible for intracellular corticosteroid regulation are glucocorticoid receptors (grs) and the ...

First analysis of digenean populations in Seriola dumerili (Risso, 1810), (Teleostei: Carangidae) from the Algerian Coast: New host record for Lecithocladium excisum (Rudolphi, 1819) Lühe, 1901

Helminthologia
The primary objective of this study is to describe and analyze the digenean fauna of the greater amberjack, Seriola dumerili, in Algeria. To achieve this, a total of 121 specimens of S.

Differential Cellular Response to Mercury in Non-Farmed Fish Species Based on Mitochondrial DNA Copy Number Variation Analysis

Biology
Mercury (Hg) pro-oxidant role on biological systems and its biogeochemical cycle represent a serious threat due to its persistence in marine environment.

Sequence capture analysis determines spatial and temporal stock contributions to a mixed coastal anadromous fishery

Journal of Fish Biology, EarlyView.
Abstract Employing a citizen science model of partnerships with recreational and commercial fishers, we collected 5298 fin‐clip samples of striped bass Morone saxatilis over a 2‐year period and a broad geographic area that encompassed a majority of the species migratory range.

Bony fish genomes: Status and gaps

Journal of Fish Biology, EarlyView.
Abstract Bony fish constitute an exceptionally species‐rich group of aquatic vertebrates, comprising more than 95% of all living fish. The adaptive processes on the diversity of environments they inhabit make them a highly diverse group from taxonomic, morphological and evolutionary standpoints.

Fish welfare in a changing world: New developments and current challenges

Journal of Fish Biology, EarlyView.
Abstract The welfare of non‐human animals is central to ethical discussions on animal use, with increasing attention to fish welfare across research, aquaria, aquaculture, and fisheries. This paper reviews current theoretical approaches to animal welfare and recent advances in defining and assessing fish welfare since the seminal paper by Huntingford ...

Assessing local adaptation and divergence at early life stages within Eastern Baltic cod (Gadus morhua)

Journal of Fish Biology, EarlyView.
Abstract Many commercially exploited fish stocks have declined over the last few decades. It is therefore essential to identify natural populations and understand local adaptation for sustainable management. Salinity is a key environmental factor shaping local adaptation, and adaptive trait divergence often occurs at the egg and larval stages.

Chronic thermal stress affects growth, liver morphology and molecular responses but allows recovery at optimal temperature in juvenile zebrafish (Danio rerio)

Journal of Fish Biology, EarlyView.
Abstract Climate‐driven aquatic heatwaves pose an increasing threat to fish populations by inducing prolonged thermal stress. However, the resilience of teleosts to chronic heat exposure and their capacity for recovery remains poorly understood. This study investigated the effects of chronic high‐temperature exposure on juvenile zebrafish (Danio rerio).

From occasional records to regular presence: Increasing occurrence of the bastard grunt Pomadasys incisus in the French Ligurian Sea (northwestern Mediterranean)

Journal of Fish Biology, EarlyView.
Abstract The bastard grunt Pomadasys incisus (Bowdich, 1825), an Atlantic teleost, has recently been recorded at multiple sites along the French Ligurian Sea. Three juveniles were captured in Villepey Lagoon, while several groups of sub‐adult and adult individuals were observed at Cagnes‐sur‐Mer and Monaco between 2020 and 2024.
