Evaluating and Advancing the Use of Shore‐Based Observers for Scientific Sampling and Catch Verification in High‐Volume Fisheries

open access: yesFisheries Management and Ecology, EarlyView.
ABSTRACT Shore‐based observers are increasingly being used in place of at‐sea observers to monitor and sample commercial fisheries catch. However, few evaluations assess whether these programs meet their stated goals or how to optimize them, and industry data are rarely tested for accuracy despite serving as the foundation for catch accounting.

Lack of Lumpfish (Cyclopterus lumpus) Susceptibility to the Infectious Salmon Anaemia Virus (ISAV) Using In Vivo Challenges

open access: yesJournal of Fish Diseases, EarlyView.
ABSTRACT Infectious salmon anaemia virus (ISAV) can cause disease and mortality in Atlantic salmon (Salmo salar). The virus is endemic in several regions including the Atlantic coast of Canada. Lumpfish (Cyclopterus lumpus) are increasingly utilised as cleaner fish to control sea lice levels in Atlantic salmon farms.

The Abrupt and Persistent Decline in Recruitment Success in Northeast Arctic Cod: A Review of Probable Causes

open access: yesFish and Fisheries, Volume 27, Issue 3, Page 643-659, May 2026.
ABSTRACT Most of the previously large cod stocks in the North Atlantic are depleted to very low levels. A notable exception has been the Northeast Arctic cod inhabiting the Barents Sea. This cod stock reached a record high level around 2013, but since then has declined sharply, with older fish being fished out and few new recruits entering the stock ...

The Windy City Rookery: Movement and Activity Patterns of Black‐Crowned Night Herons (Nycticorax nycticorax) in a Human‐Dominated Landscape

open access: yesEcology and Evolution, Volume 16, Issue 4, April 2026.
Black‐crowned night herons (BCNH) are a cryptic, widely distributed colonial wading bird. Despite showing regional declines in North America, this species has successfully adapted to colonize urban areas. In this study, our team used GPS/GSM transmitters to explore the space use, habitat use, and diel activity patterns of BCNH breeding at the largest ...

Consequences of temperature and temperature variability on swimming activity, group structure, and predation of endangered delta smelt [PDF]

open access: yes, 2019
The effects of water temperature on individual and group movement behaviour in prey fish can affect ecological interactions such as competition and predation, but how variability in temperature influence fish behaviour is less understood.
