Post‐Release Mortality of European Bass (Dicentrarchus labrax) Discarded From Small‐Scale Estuarine Fishing

Fisheries Management and Ecology, EarlyView.
ABSTRACT Estuaries provide essential habitats for many fish species, but their confined and accessible nature may increase fish vulnerability to capture, and few empirical studies have quantified the value of restricting net fisheries in such areas.

Acoustic estimates of spawning cod in the Lofoten area in 1982 and 1983

, 1984
The main spawning grounds for Arctic cod, the Lofoten area, were covered by acoustic surveys 7 times in 1983 and 12 times in 1983 during the prespawning and spawning season. The results indicated a spawning stock in the area of approximately 80 million specimens in 1982. and 50 million spec-imens in 1983. These figures were less than half the estimated

Disentangling the Drivers of a Piscivorous Intra‐Annual Cohort and the Contributions of Three Cohorts to Early‐Year Class Strength in Pikeperch (Sander lucioperca)

Fisheries Management and Ecology, EarlyView.
ABSTRACT Using pikeperch (Sander lucioperca) as a model species, we investigated the factors influencing fluctuations in the abundance of piscivorous intra‐annual cohorts and assessed the role of three distinct cohorts: extremely small (ES), ordinary (or mid‐sized) fingerlings, and piscivorous in shaping year‐class strength.

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, EarlyView.
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 ...

Fleet Behaviour Under Economic Uncertainty: Multi‐Species Policy Scenarios for the Purse‐Seine Fishery

Fisheries Management and Ecology, EarlyView.
ABSTRACT Managing fishing effort remains a central challenge in achieving sustainability in many fisheries, particularly where high‐value species attract intense competition. In the Indian Ocean tropical tuna fishery, understanding how fishers respond to changing bio‐economic conditions is essential for developing effective management.

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

Fisheries Management and Ecology, EarlyView.
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).
