Sex‐Specific Atlantic Salmon Upstream Passage and Fallback at a Natural Cascade After Dam Removal

Fisheries Management and Ecology, EarlyView.
ABSTRACT In the Boquet River (NY, USA) a low‐head dam set above a ~200‐m bedrock cascade was removed in 2015. We used radio‐telemetry to assess landlocked Atlantic salmon passage at the remaining cascade (2020, 2022). Across years, 52% of males (13/25) attempted cascade passage whereas females made no discernable attempts (0/11).

Chinook salmon depth distributions on the continental shelf are shaped by interactions between location, season, and individual condition

Movement Ecology
Background Ecological and physical conditions vary with depth in aquatic ecosystems, resulting in gradients of habitat suitability. Although variation in vertical distributions among individuals provides evidence of habitat selection, it has been ...

Variability in Fecundity–Body Size Relationships for Atlantic Salmon Associated With Body Condition and Life History

Fisheries Management and Ecology, EarlyView.
ABSTRACT While body size is the primary driver of fecundity, other factors may contribute to variation in these relationships. Anadromous populations of Atlantic salmon (Salmo salar) have diverse life histories, and fisheries management relies on accurate fecundity estimates.

Spatial and temporal patterns of covariation in productivity of Chinook salmon populations of the northeastern Pacific Ocean

Canadian Journal of Fisheries and Aquatic Sciences, 2018
We expand on previous analyses of environmental factors related to productivity of Chinook salmon (Oncorhynchus tshawytscha) populations by analysing data on adult recruits per spawner from 24 wild (not hatchery) Chinook salmon stocks from Oregon through

The Staircase Chart: Visualising Vertical and Cross‐Shelf Movements and Dispersal of Early‐Life Fish, Applied to Japanese Jack Mackerel

Fisheries Oceanography, EarlyView.
ABSTRACT Dispersal during early life stages is a critical process shaping marine fish connectivity and population dynamics, yet direct field observations at the individual level remain elusive. This has limited our understanding of the factors controlling dispersal, including the impact of active swimming by larvae and juveniles. Here, we present a new

On steadyness of stereotypes in conceptions on marine ecology of pacific salmons (Oncorhynchus spp.)

Известия ТИНРО, 2017
Some conceptions on marine ecology of pacific salmons (Oncorhynchus spp.), established in the second half of the last century, are discussed from critical position, as overemphasizing of the sea surface temperature influence on distribution of salmons ...

Effects of Dissolved Oxygen and Hypoxia on Catch Rates of Nearshore Groundfishes in a Recreational Hook and Line Fishery

Fisheries Oceanography, EarlyView.
ABSTRACT Global climate change is intensifying ocean deoxygenation, particularly in eastern boundary current systems such as the California Current. This study investigates the impact of hypoxic events on a nearshore, multispecies recreational groundfish fishery along the Oregon coast.

Caring for Pacific salmon: Reconsidering salmon‐human relationships

Anthropology Today
Caring for Pacific salmon – one of the most iconic creatures of the North American West Coast – is not a straightforward task but is based on diverse understandings and relationships between salmon, people and the more‐than‐human environment. Local small‐scale interactions, in particular, shape individual motivations to care for these fish and ...
