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

open access: yesFisheries 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.

Environmental Drivers of Jumbo Squid During Fishery Collapse in the Gulf of California (2019–2024)

open access: yesFisheries Oceanography, EarlyView.
ABSTRACT The jumbo squid (Dosidicus gigas) is a cephalopod endemic to the eastern Pacific with significant ecological and economic importance. Its exploitation in the Gulf of California (GC) peaked in the 1990s, with catches exceeding 100,000 tons, but collapsed in 2009 and virtually disappeared by 2015, largely due to environmental changes and ...

Stage‐Specific Indicators of Northern Yellowtail Rockfish (Sebastes flavidus) Recruitment in the California Current Ecosystem

open access: yesFisheries Oceanography, EarlyView.
ABSTRACT Oceanographic and ecological conditions can be used to inform forecasts and decision‐making for marine resources, but the dominant drivers of recruitment variability remain poorly understood for many fish stocks. We developed a conceptual life‐history model of the oceanographic and ecological variables that influence the recruitment of ...

Effects of Dissolved Oxygen and Hypoxia on Catch Rates of Nearshore Groundfishes in a Recreational Hook and Line Fishery

open access: yesFisheries Oceanography, EarlyView.
ABSTRACT Global climate change is intensifying ocean deoxygenation, particularly in eastern boundary current systems such as the California Current. This study investigates the impact of hypoxic events on a nearshore, multispecies recreational groundfish fishery along the Oregon coast.
