Dietary modulation of antimicrobial peptides (HAMP and LEAP2) in Chinook salmon (Oncorhynchus tshawytscha) fed a phytobiotic functional diet: Integrated genomic characterisation and tissue‐specific expression

Journal of Fish Biology, EarlyView.
Abstract Antimicrobial peptides (AMPs) are key components of the innate immune system in fish, providing rapid protection against microbial pathogens. Among these, the liver‐expressed antimicrobial peptides (LEAPs), comprising LEAP‐1 (hepcidin; HAMP) and LEAP‐2, play central roles in host defence and iron regulation.

Insights Into the Structural Features, Codon Usage Patterns, and Phylogenetic Analysis in <i>Neoniphon argenteus</i> (Teleostei: Holocentriformes) Based on Complete Mitochondrial Genome. [PDF]

Ecol Evol
This study provides important foundational information for further research on the mitochondrial genomes of Holocentridae. ABSTRACT Neoniphon argenteus, a widely distributed nocturnal coral reef fish in the family Holocentridae, plays an important role in maintaining coral reef ecosystem health, yet its phylogenetic position remains poorly resolved.

Insights into diet and niche separation in the context of prey availability between two sympatric whiprays in a tropical intertidal estuary

Journal of Fish Biology, EarlyView.
Abstract Increasing evidence supports associations between various elasmobranch species and estuarine habitats, particularly during early life stages. However, with substantial knowledge gaps surrounding spatial habitat use and trophic ecology of estuary‐associated species in Australia, we cannot reliably assess the functional importance of these areas

Biofluorescence in polar zoarcid eelpouts: The Arctic eelpout Lycodes reticulatus (Reinhardt, 1835) and the Antarctic eelpout Pachycara brachycephalum (Pappenheim, 1912)

Journal of Fish Biology, EarlyView.
Abstract Biofluorescence is widespread among marine fish but remains poorly documented in polar ecosystems. Using hyperspectral imaging, we report fluorescent emissions in two polar zoarcid eelpouts. A captive Antarctic eelpout (Pachycara brachycephalum) displayed uniform bright green fluorescence (~500–520 nm), whereas an Arctic eelpout (Lycodes ...

Integrated multitissue analysis reveals distinct oxidative stress responses during recovery from cold shock in the Amazonian fish Colossoma macropomum

Journal of Fish Biology, EarlyView.
Abstract Tambaqui (Colossoma macropomum) is a tropical fish widely cultivated in South America. The increasing demand for this species has heightened interest in its cultivation in subtropical regions with greater thermal variability, where cold shock may induce oxidative stress. This study evaluated the effects of cold shock and subsequent recovery on

The role of behavioural measures in successful fishway passage during seasonal brown trout (Salmo trutta) migration

Journal of Fish Biology, EarlyView.
Abstract Successfully overcoming lateral barriers in rivers is crucial for longitudinal fish migration and is influenced mainly by fishway design, environmental variability and/or individual behavioural traits. Although behavioural traits are well studied in many contexts, their role in predicting fishway passage success in the wild remains poorly ...

Contrasting population genetic structures of freshwater eels (Anguilla marmorata, A. bicolor, A. mossambica) from Madagascar

Journal of Fish Biology, EarlyView.
Abstract Freshwater eels (genus Anguilla) are of major biological and commercial interest due to their complex catadromous life cycle and as a high‐value fishery resource, but the biology of tropical species is still poorly understood. This study investigates the genetic integrity, diversity and population structure of three species of tropical eels ...

Continuous darkness is associated with improved growth performance during a high‐temperature period and sex‐specific modulation of early gonadal development in juvenile yellowtail (Seriola quinqueradiata)

Journal of Fish Biology, EarlyView.
Abstract Selective breeding of yellowtail (Seriola quinqueradiata) is expanding in Japan, increasing the demand for practical reproductive control tools in commercial aquaculture to reduce genetic risks from escapees. Slowing early gonadal development through environmental manipulation may support future sterilization strategies, particularly when ...
