Occurrence of Kabatana takedai (Microspora) in Juvenile Masu Salmon (Oncorhynchus masou) reared at Varying Water Temperatures in a Hatchery [PDF]

, 2001
Infections with the microsporidian parasite Kabatana takedai (Awakura, 1974) were monitored for juvenile masu salmon (Oncorhynchus masou) held at various water temperatures controlled using river and spring waters in the Chitose Hatchery, Hokkaido, Japan.

Pathophysiological Mechanisms of Emaciation Syndrome in Plectropomus leopardus: Insights From Histology and Transcriptomics

Animal Research and One Health, EarlyView.
Integrated phenotypic, histological, transcriptomic, and validation analyses reveal that emaciation syndrome in Plectropomus leopardus is associated with intestinal structural damage, hepatic metabolic remodeling, and muscle protein degradation, highlighting coordinated multi‐tissue alterations underlying disease progression.

Ploidy effects on hatchery survival, deformities, and performance in Atlantic salmon (Salmo salar)

, 2011
The production of sterile triploid Atlantic salmon (Salmo salar) may help address the increasing pressure on the industry to reduce potential breeding between farmed escapees and wild fish populations.

The identification of individuals with hatchery and natural origin in a mixed sample of Amur River chum salmon by Otolith microchemistry

Aquaculture and Fisheries, 2023
We estimated the proportion of hatchery and natural fall spawning chum salmon returning to the Amur River using chemical markers specific to hatchery-origin fry.

Evidence for adaptive explanations of semelparity in animals

Biological Reviews, EarlyView.
ABSTRACT Semelparity, the reproductive strategy of reproducing once, is widespread but uncommon in animals. Classes of models to explain the evolution of semelparity are based either on age structure and mortality schedules – demographic models in which high post‐reproductive mortality risk favours high reproductive effort and semelparity results from ...

Short‐Term 6PPD‐Q Exposure alters Tight‐Junction‐Related Gene Expression Without Acute Lethality in Japanese Medaka Oryzias latipes

Journal of Applied Toxicology, EarlyView.
ABSTRACT 6PPD‐quinone (6PPD‐Q), a transformation product of the tire antioxidant 6PPD, causes acute mortality in several salmonid species, but its toxicity varies markedly among fish species. Disruption of vascular‐barrier integrity and inflammatory signaling has been proposed as a key mechanism of 6PPD‐Q toxicity.

Recent salmon declines: a result of lost feeding opportunities due to bad timing? [PDF]

PLoS ONE, 2010
As the timing of spring productivity blooms in near-shore areas advances due to warming trends in global climate, the selection pressures on out-migrating salmon smolts are shifting.

Analysis of Gene Expression in Aedes aegypti Suggests Changes in Early Genetic Control of Mosquito Development

Journal of Experimental Zoology Part B: Molecular and Developmental Evolution, EarlyView.
ABSTRACT Aedes aegypti, a critical vector for tropical diseases, poses significant challenges for studying its embryogenesis due to difficulties in removing its rigid chorion and achieving effective fixation for in situ hybridization. Here, we present novel methodologies for fixation, dechorionation, DAPI staining, and in situ hybridization, enabling ...

Maintaining a wild phenotype in a conservation hatchery program for Chinook salmon: The effect of managed breeding on early male maturation.

PLoS ONE, 2019
In many salmonid species, age and size at maturation is plastic and influenced by the interaction between genetic and environmental factors. Hatchery reared salmon often mature at an earlier age and smaller size than wild fish. Modern salmon conservation
