Impact of Environmental Conditions on the Spawning Migration of Sea Trout (Salmo trutta L.) in Two Large, Sub‐Arctic River Systems

open access: yesFisheries Management and Ecology, Volume 33, Issue 5, Page 879-893, October 2026.
ABSTRACT The global decline in salmonid stocks has increased the need for knowledge of local adaptations and life history strategies of salmonids. In this study, we used radio‐telemetry tracking data from sea trout populations in two large high‐latitude rivers to model upstream spawning migration speed of trout in response to prevailing environmental ...

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

open access: yesFisheries Management and Ecology, Volume 33, Issue 5, Page 963-976, October 2026.
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).

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

open access: yesFisheries Management and Ecology, Volume 33, Issue 5, Page 1002-1017, October 2026.
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.

Long‐Term Fish Assemblage Responses to Instream Restoration in Boreal Streams: Insights From a 24‐Year BACI Study

open access: yesFreshwater Biology, Volume 71, Issue 10, October 2026.
ABSTRACT Freshwater ecosystems are increasingly threatened by human activities and climate change, emphasizing the need for effective habitat restoration supported by long‐term monitoring. We examined fish species responses to instream restoration in six boreal streams in northern Finland over a 24‐year period (1999–2022) using a Before–After–Control ...

Brown trout anadromy in the Anthropocene

open access: yes
Recent human-induced changes in both marine and freshwater environments are likely to alter adaptative landscapes in migratory species that utilise both habitats. Anadromous salmonids, like the brown trout (Salmo trutta), have recently experienced considerable changes in the marine environment due to a large increase in aquaculture-induced pathogens ...
