Impact of an Environmental Index of Recruitment on the Stock Assessment for Petrale Sole ( Eopsetta jordani Lockington, 1878) in the California Current Ecosystem

ABSTRACT Stock assessments provide key scientific input for managing fisheries. Age‐structure information is important for these assessments because it provides the foundation for estimating recruitment, which impacts estimates of future spawning biomass and other assessment para...

Analysis of Multiple Tire Rubber-Derived Chemicals in Fish Bile and Plasma: Analytical Method and Field Assessment in Puget Sound, WA, USA

Abstract Tire rubber-derived chemicals (TRCs) are known to be highly toxic to fish, but understanding of their environmental levels and fate is still limited. This study presents a new method for the analysis of 18 TRCs, including phenylenediamines (TRC-PDs), their quinone deriva...

A collaborative e-library for stressor-response functions to improve the science underlying salmonid management

Stressor-response functions quantify relationships linking environmental stressors to biological responses, underpinning salmonid life-cycle models, restoration planning, regulatory policy, and cumulative effects assessments. Despite their importance, these stressor-response func...

Contrasting Food Web Dynamics Across Oceanographic Boundaries in Subarctic Pelagic Ecosystems

ABSTRACT Understanding the structure of pelagic food webs across multiple trophic levels is critical for elucidating species interactions, energy flow, and anthropogenic impacts on production. This study presents a comprehensive analysis of the eastern North Pacific pelagic food...
