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

Fisheries 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

Fisheries 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

Fisheries 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.

Site Fidelity, Depth Preference and Vertical Movement Patterns of Lentic and Lotic European Catfish Silurus glanis

Fisheries Management and Ecology, Volume 33, Issue 5, Page 1031-1043, October 2026.
ABSTRACT To study variables that may trigger the dispersion of the currently expanding European catfish in its native distribution limits, 42 individuals were captured from Upper Lake Constance (lentic) and 42 from two streaming tributaries (lotic), fitted with pressure and temperature loggers, and released at the site of capture (control: lotic or ...

A Review of Nonsteroidal Anti‐Inflammatory Drugs for Food‐Producing Animals With a Focus on Potential Applications for Farmed Finfish

Journal of Fish Diseases, Volume 49, Issue 10, October 2026.
ABSTRACT In finfish aquaculture, there are several inflammatory diseases impacting productivity and animal welfare, however there are limited options available to veterinarians to treat inflammation and pain in fish. Nonsteroidal anti‐inflammatory drugs (NSAIDs) are widely used in terrestrial animals raised for human consumption to treat a range of ...

Fish Poxviruses on the Rise: Prospects for Aquatic Health

Journal of Fish Diseases, Volume 49, Issue 10, October 2026.
ABSTRACT Fish poxviruses are increasingly recognised as emerging pathogens of fish and should be considered in cases of unexplained gill or skin pathology. Carp edema virus (CEV), the causative agent of koi sleepy disease in common carp and koi (Cyprinus carpio), represents the first known example.

Estrogen/Esr2b signaling‐dependent, female‐biased expression of a neuropeptide Y gene in the medaka brain

Journal of Neuroendocrinology, Volume 38, Issue 10, October 2026.
Abstract A recent study showed that female medaka lacking the estrogen receptor gene esr2b are unreceptive to male courtship and instead court other females. In this study, we investigated the brain transcriptome of esr2b‐deficient females to explore the underlying mechanisms of this behavioral phenotype, and identified npyb, one of the two ...

Development and validation of a challenge model using geosmin‐spiked feeds to obtain off‐flavor compounds in tissues of Atlantic salmon, Salmo salar

Journal of the World Aquaculture Society, Volume 57, Issue 5, October 2026.
Abstract Fish produced within recirculating aquaculture systems may develop flavors not desired by end‐consumers, hereafter “off‐flavor,” which is largely attributed to geosmin accumulation in fish tissues. To develop methods for mitigating geosmin accumulation, a reliable and reproducible method of introducing geosmin in fish tissue is needed. Current
