Nutrient and light availability control food webs and fish larvae in the Peruvian upwelling system

open access: yesLimnology and Oceanography, Volume 71, Issue 3, March 2026.
Abstract Upwelling ecosystems sustain some of the world's most productive fisheries by supplying deep‐water nutrients to the sunlit ocean surface. Yet, how spatiotemporal variability in nutrient‐upwelling and light availability regulates trophic transfer to fish remains poorly understood. We investigated these dynamics in a 36‐d mesocosm experiment off

Evaluating Post‐Survey Otolith Subsampling Strategies for a Small‐Bodied, Fast‐Growing Pelagic Fish for Inclusion in Stock Assessments

open access: yesFisheries Management and Ecology, Volume 33, Issue 1, Page 24-39, February 2026.
ABSTRACT Identifying efficient otolith subsampling strategies that maintain data quality for stock assessments is imperative given limited resources to meet age‐estimation demands of managed fish stocks. Our objective was to evaluate the performance of three different subsampling strategies: (1) fixed otolith subsampling, (2) proportional otolith ...
