Dietary nucleotide supplements influence the growth, haemato-immunological parameters and stress responses in endangered Caspian brown trout (Salmo trutta caspius Kessler, 1877)

open access: yes, 2013
A feeding trial was conducted to evaluate the effects of Optimun, a commercial nucleotide (NT) product, on the growth, haemato-immunological and serum biochemical parameters and stress responses of Caspian brown trout fingerlings (average initial weight ...

Temperature‐dependent alterations in the proteome of the emergent fish pathogen Edwardsiella piscicida

open access: yesJournal of Fish Diseases, EarlyView.
Abstract Edwardsiella piscicida is an emerging bacterial pathogen and the aetiological agent of edwardsiellosis among cultured and wild fish species globally. The increased frequency of outbreaks of this Gram‐negative, facultative intracellular pathogen pose not only a threat to the aquaculture industry but also a possible foodborne/waterborne public ...

The Impact of Exposure Dosage and Host Genetics on the Shedding Kinetics of Flavobacterium psychrophilum in Rainbow Trout

open access: yesJournal of Fish Diseases, EarlyView.
ABSTRACT Flavobacterium psychrophilum, the causative agent of bacterial cold water disease (BCWD), is one of the leading pathogens in rainbow trout (Oncorhynchus mykiss) aquaculture. To date, there is little knowledge of the transmission kinetics of F. psychrophilum over the course of infection.

Diplostomum‐Induced Sac Formation in Lenses of Ameiurus Bullheads: A Host Defence Response?

open access: yesJournal of Fish Diseases, EarlyView.
ABSTRACT Trematodes of the genus Diplostomum (Diplostomidae) are widely distributed and significant fish pathogens known for causing a range of negative effects. Any mechanism that protects the host from the parasite thus represents an evolutionary advantage.

A long-term study of the impact of the invasive species Eurasian minnow Phoxinus phoxinus on brown trout Salmo trutta production in a high mountain lake, Southern Norway

open access: yesFauna Norvegica
The shallow Lake Skjerja was originally one of the most outstanding brown trout lakes on the Hardangervidda mountain plateau. During the period 1973–1985, the annual yield was on average 3.35 kg ha-1.

Spleen as an Alternative Tissue for Estimating Tetracapsuloides bryosalmonae Load, Prevalence and Its Relationship With Proliferative Kidney Disease in Brown Trout

open access: yesJournal of Fish Diseases, EarlyView.
ABSTRACT Accurate pathogen detection is essential in fish health management and disease prevention. Pathogens often target different host tissues, and monitoring alternative target organs can provide important insights into disease progression. We evaluated the spleen as an alternative to the kidney for estimating the load and prevalence of the ...

Biocentric Work in the Anthropocene: How Actors Regenerate Degenerated Natural Commons

open access: yesJournal of Management Studies, EarlyView.
Abstract As natural commons vital to selves, organizations, and institutions collapse under cumulative anthropogenic pressures, can human agency still reverse some of the damage already done? This article explores how emerging forms of social symbolic work regenerate degenerated natural commons.

Annual variation in riverscape habitat use by a diadromous fish before oceanic migration

open access: yesJournal of Zoology, EarlyView.
Migratory animals often face high mortality risks during migration, with smaller individuals particularly vulnerable. This study reveals that smaller pre‐migrants of masu salmon (Oncorhynchus masou) stayed longer in different riverscape habitats (nursery and transitional), with variation between years, to reach large size prior to migration.
