Identification of new participants in the rainbow trout () oocyte maturation and ovulation processes using cDNA microarrays [PDF]

open access: yes, 2006
BACKGROUND: The hormonal control of oocyte maturation and ovulation as well as the molecular mechanisms of nuclear maturation have been thoroughly studied in fish. In contrast, the other molecular events occurring in the ovary during post-vitellogenesis

Contemporary Methods for Capturing Juvenile Salmonids in the Marine Environment

open access: yesFish and Fisheries, Volume 27, Issue 2, Page 160-178, March 2026.
ABSTRACT Anadromous salmonids play vital roles in marine and freshwater ecosystems. The most abundant of these fishes—Pacific salmon (Oncorhynchus spp.)—are integral to coastal ecosystems and communities across the North Pacific Rim, but numerous populations are experiencing dramatic declines, particularly towards the south of their range.

Existing Soundscapes and the Impact of Noise on the Welfare of Farmed Salmonids: A Review

open access: yesReviews in Aquaculture, Volume 18, Issue 2, March 2026.
ABSTRACT Understanding how farmed salmonids sense and respond to their environment is key to securing animal welfare and efficient production. However, hearing has rarely received attention, despite the omnipresence of underwater sound and its potential effects.

Experimental analysis of the effect of low water temperature on oogenesis of juvenile chum salmon

open access: yesИзвестия ТИНРО
The state of gonads is examined for juvenile chum salmon exposed for two weeks at low water temperature, for different stages of their embryonic-larval development.

Characterization of salmon‐foraging harbor seals (Phoca vitulina) in the Erimo region, Hokkaido, Japan, using finite mixture models

open access: yesThe Journal of Wildlife Management, Volume 90, Issue 2, February 2026.
Finite mixture models revealed that older, larger harbor seals specialize in salmon predation at setnets in Hokkaido, Japan, suggesting targeted management strategies focusing on these specialist individuals could effectively reduce fishery conflicts while protecting the broader seal population.

Seasonal changes in growth of coho salmon (Oncorhynchus kisutch) off Oregon and Washington and concurrent changes in the spacing of scale circuli [PDF]

open access: yes, 2005
In this study we present new information on seasonal variation in absolute growth rate in length of coho salmon (Oncorhynchus kisutch) in the ocean off Oregon and Washington, and relate these changes in growth rate to concurrent changes in the spacing of

Salmon watershed archetypes: A clustering of cumulative pressures and climate change

open access: yesEcological Solutions and Evidence, Volume 7, Issue 1, January–March 2026.
Cumulative effects of land‐use change and climate change are leading to biodiversity decline globally. Spatial analyses of cumulative pressures that distill complexity and provide actionable information for the management of cumulative pressures on vulnerable species are needed.

Effect of thyroxine on hatching and on postembryonic growth in Brachydanio rerio, Cyprinus carpio, Labeo rohita, Cirrhina mrigala and Catla catla [PDF]

open access: yes, 1994
Studies on the effect of thyroxine on the eggs and postembryonic growth of Brachydanio rerio, Cyprinus carpio, Labeo rohita, Cirrhina mrigala and Catla catla have been carried out.

Bridging Ecology and Geosciences in Riverscapes: Implications for Process‐Based Restoration

open access: yesEcological Research, Volume 41, Issue 1, January 2026.
In this paper, we synthesize studies that integrally examine geological and ecological processes across different scales and components of riverscapes, including geohydrological processes. Finally, we identify both scientific and practical challenges that must be addressed to bridge the gap between basic‐science implications and their implementation in

Unraveling multipredator impacts in salmon‐bearing rivers using quantitative DNA metabarcoding

open access: yesEcological Applications, Volume 35, Issue 8, December 2025.
Abstract Ecological impacts of invasive species are mounting as their numbers and geographic extent continue to increase. Across extensive parts of their range, Pacific salmon (Oncorhynchus spp.) smolts face an expanding gauntlet of nonnative predators during their seaward migration.
