Modelling relationships between juvenile brown trout (Salmo trutta L.) density and landscape characteristics: Integration of electrofishing data and spatial data to assess population status

open access: yesJournal of Fish Biology, EarlyView.
Abstract Brown trout (Salmo trutta L.) are ecologically and economically important, but like many salmonids their populations are declining. Trout exhibit a high level of phenotypic plasticity, ranging from freshwater residency to anadromy. This complexity causes problems for assessment and constrains application of adult catch‐based assessment methods

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

open access: yesJournal 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.

Taxonomic inflation in fish systematics: A critical review with illustrative evidence assessment and integrative case study of the Salmo trutta Complex

open access: yesJournal of Fish Biology, EarlyView.
Abstract Fish species are being described at an accelerating rate, but a substantial fraction of recent descriptions rests on evidentiary standards too weak to distinguish genuine species‐level discontinuities from intraspecific variation, local adaptation and the artefacts of single‐marker analyses, a pattern of taxonomic inflation with documented ...

Resource use by threatened, native Bull Trout (Salvelinus confluentus) in the presence of two non‐native salmonids

open access: yesJournal of Fish Biology, EarlyView.
Abstract Introduction of non‐native species contributes to the global decline of freshwater fishes by disrupting the diet and resources of native species through competition. Despite the potential for non‐native trout (Family: Salmonidae) to compete with native trout, non‐native trout species have been widely introduced worldwide to support ...

Thermal tolerance and acclimation limits in bull trout (Salvelinus confluentus) alevin

open access: yesJournal of Fish Biology, EarlyView.
Abstract The critical thermal maximum (CTmax) of bull trout (Salvelinus confluentus) alevin was measured after 3 weeks of acclimation to 4–21°C. CTmax increased from 24.3 at 4°C to 26.7 at 9°C, plateaued between 9 and 12°C (26.9°C), and declined to 25.9°C at 15°C.
