Aquatic Conservation: Marine and Freshwater Ecosystems, Volume 36, Issue 2, February 2026.ABSTRACT Commercial fishing is often assumed to have greater impacts than recreational fishing, and many fisheries assessments overlook the latter. Yet, numerous coastal and freshwater fish populations are subject to both fishing types and environmental pressures, all influencing biomass, body size and community structure and making management outcomes

Growth of different year classes of smelt Osmerus eperlanus L. in Lake Tyrifjorden, Norway
Fauna Norvegica, 1982 Smelt Osmerus eperlanus L. were collected during spawning run in May in Lake Tyrifjorden in southern Norway. Age determination was carried out by otoliths. Fish length (Y) and otolith radius (X) were correlated (r = 0.954).

Ecology and Evolution, 2018 Reproduction of external fertilizing vertebrates is typically constrained to either fresh or salt water, not both. For all studied amphibians and fishes, this constraint includes immotile sperm that are activated after ejaculation only by the specific ...

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.

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 ...

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 smelt Osmerus eperlanus in Scotland
, 1996 Smelt populations have been recorded since the 18th Century from at least 15 rivers in Scotland, but over the last Century the species has suffered a severe decline and has disappeared from all its former sites except the rivers Cree, Forth and Tay. These populations must now be regarded as having high conservation importance.

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.
