Observer coverage and interaction rates determine the choice between design‐based and machine learning bycatch estimators for rare species

Conservation Biology, EarlyView.
Abstract Robust estimates of the magnitude of protected species bycatch are essential for effective fisheries management and marine conservation. Existing bycatch estimation methods typically struggle to accurately and precisely estimate the bycatch of rare species as a result of the statistical assumptions necessary to overcome infrequent encounters ...

Examining the Impact of Derelict Pots on Blue Crab (Callinectes sapidus) Catch and Harvest Within a Recreational Fishery

Fisheries Management and Ecology, EarlyView.
ABSTRACT Derelict fishing gear can negatively affect marine ecosystems through mortality in coastal environments. This study explored the impact of derelict and active crab pots on recreational blue crab (Callinectes sapidus) catch rates and landings in a Mid‐Atlantic estuary by deploying experimental pots in four habitat strata within three sections ...

Biophysical Factors Controlling Spatiotemporal Variability in Fishes' Early Life History Distribution in the Kattegat Ecosystem

Fisheries Oceanography, EarlyView.
ABSTRACT The Kattegat Sea acts as a nursery area for several fishes, exhibiting complex ichthyoplankton dynamics influenced by environmental factors and species‐specific traits. We investigated factors influencing spatiotemporal variability in yolk‐sac larvae presence and areal density for three economically and ecologically important fishes: sandeel ...

Bathymetry beneath ice shelves of western Dronning Maud Land, East Antarctica

, 2020
The lack of consistent and reliable estimates of the bathymetry beneath the ice shelves of western Dronning Maud Land is addressed by inverting airborne gravity data to model the underlying bathymetry.

Identifying the Drivers of Newfoundland Capelin Recruitment After a Breakdown in the Environment–Recruitment Relationship

Fisheries Oceanography, EarlyView.
ABSTRACT Environment‐recruitment relationships often break down over time. This can occur because of spurious results from testing numerous environmental variables in the original analyses or from relative changes in the importance of specific environmental drivers over time.

Under the cover of darkness: Foraging behaviour increases on cloudy, new moon nights in a pelagic seabird

Ibis, EarlyView.
While many visual predators feed exclusively during the day, others exploit foraging opportunities at night, although the efficiency with which they do so is strongly influenced by ambient light levels. We investigated the influence of variation in nocturnal light on the foraging behaviour of a small pelagic seabird, the European Storm‐petrel ...
