Stable Isotope Analyses of Yellowfin and Blackfin Tuna Eye Lenses Reveal Life History Patterns

open access: yesFisheries Oceanography, EarlyView.
ABSTRACT Spatial geography, ontogenetic movement, and trophic patterns of mobile species are key elements of species life history, and knowledge of them is critical for effective marine resource management. For yellowfin tuna (Thunnus albacares; YFT) and blackfin tuna (Thunnus atlanticus; BLFT), residency durations and ontogenetic movements in the Gulf

Divergent Environmental Niches and Climate Vulnerabilities of Jonah Crab (Cancer borealis) and Atlantic Rock Crab (Cancer irroratus)

open access: yesFisheries Oceanography, EarlyView.
ABSTRACT Jonah crab and Atlantic rock crab in the United States are currently assessed by National Oceanic and Atmospheric Administration climate change vulnerability assessments under the category Cancer crabs due to a dearth of species‐specific information across the attributes assessed.

Weathering the Storm: Effects of a Hurricane‐Induced Thermal Disturbance on a Juvenile Atlantic Halibut (Hippoglossus hippoglossus) Hotspot in Nova Scotia, Canada

open access: yesFisheries Oceanography, EarlyView.
ABSTRACT Atlantic Halibut has recently become the most valuable groundfish in Atlantic Canada following population recovery, and the benthic habitat characteristics of their aggregation areas have been identified as a key outstanding ecological knowledge gap for the species. In 2022, during a multi‐year acoustic tracking study in a key juvenile hotspot

Recent Anomalously Warm Ocean Conditions and Changes in the Migration and Spawning Distribution of Chub Mackerel (Scomber japonicus) in the Western North Pacific

open access: yesFisheries Oceanography, EarlyView.
ABSTRACT Extreme ocean warming has become increasingly pronounced in the western North Pacific in recent years. Coincident with this, both the egg abundance and the catch per unit effort (CPUE) of chub mackerel (Scomber japonicus) in fisheries targeting southward‐migrating adults have decreased.

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

open access: yesIbis, 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 ...
