Evaluating ecosystem caps on fishery yield in the context of climate stress and predation [PDF]

open access: yesEcological Applications, Volume 35, Issue 3, April 2025.
Abstract Ecosystem‐based fisheries management strives to account for species interactions and ecosystem processes in natural resource management and conservation. In this context, ecosystem‐wide caps on total fishery catches have been proposed as one tool to manage multispecies fisheries with an ecosystem approach.
