Modern state of aquatic biological resources of the Amur River basin and directions of their research

Известия ТИНРО, 2020
Current status of aquatic biological resources in the middle and lower parts of the Amur River basin, including Lake Khanka and the Amursky Liman, is assessed. Generally high abundance of the water organisms is noted, but a downward trend is revealed. In

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

The 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.

Groundtruthing of pelagic forage fish detected by hydroacoustics in a whale feeding area using environmental DNA

Environmental DNA, 2020
Conservation of whales, considered as umbrella species in marine environments, requires to be able to understand their relationships with ecosystem components such as prey species, including pelagic fish. However, studying such relationships in nature is

Wild and Naturalized Hatchery Brown Trout: A Comparison of Movement, Space Use, and Survival in a Large Lake

Fisheries Management and Ecology, Volume 33, Issue 1, Page 14-23, February 2026.
ABSTRACT Most research comparing wild and hatchery‐produced fish focuses on recently stocked individuals. As a result, these studies only investigate the behavior of naive hatchery fish, leaving a knowledge gap regarding long‐term survivors. We compared the movement, space use, and survival of wild and hatchery‐reared brown trout (Salmo trutta) that ...

Radiodiagnostic method for studying swimbladder inflammation caused by Anguillicola crassus (Nematoda:Dracunculoidea) [PDF]

, 1998
The nematode Anguillicola crassus appeared in Europe about 15 yr ago, and has subsequently become recognised as a cause of major pathological lesions in the swimbladder of the European eel Anguilla anguilla. The radiographic method reported in this paper

Strike Behavior and Behavioral Responses to Retrieval by Northern Pike (Esox lucius) During Ice Angling

Fisheries Management and Ecology, Volume 33, Issue 1, Page 119-133, February 2026.
ABSTRACT Behavior of fish during catch and release has not been well studied despite its potential importance for fish conservation and welfare. We used underwater video footage to examine behaviors of ice‐angled northern pike (Esox lucius) during approach and retrieval.

The likely effects of thermal climate change on vertebrate skeletal muscle mechanics with possible consequences for animal movement and behaviour [PDF]

, 2019
Climate change can involve alteration in the local temperature that an animal is exposed to, which in turn may affect skeletal muscle temperature.

Status Assessments for Two Endangered Populations of Vendace (Coregonus albula) and Evidence That Their Abundance Is Modulated by Percid Fishes

Aquatic Conservation: Marine and Freshwater Ecosystems, Volume 36, Issue 1, January 2026.
ABSTRACT The study of low‐latitude populations can inform our understanding of how cold‐adapted species might respond to environmental change. The vendace (Coregonus albula) is a lacustrine fish that is distributed across northern Europe. In the UK, there are two extant native vendace populations.
