Page 3: Research news on fishery management

Fishery management methods comprise the suite of scientific, regulatory, and operational tools used to maintain fish populations and associated ecosystems at or near defined biological and socioeconomic reference points. They include stock assessment methodologies (e.g., age-structured or surplus-production models), harvest control rules, effort and catch limitations (quotas, size limits, gear restrictions), spatial and temporal closures, rights-based systems (ITQs, TURFs), and ecosystem-based approaches that integrate multispecies interactions and environmental variability. These methods rely on monitoring programs, statistical modeling, and adaptive management frameworks to adjust exploitation rates in response to observed stock status, uncertainty, and management objectives such as maximum sustainable yield or precautionary conservation targets.

Counting salmon is a breeze with airborne eDNA

During the annual salmon run last fall, University of Washington researchers pulled salmon DNA out of thin air and used it to estimate the number of fish that passed through the adjacent river. Aden Yincheong Ip, a UW research ...

New deep-learning tool can tell if salmon is wild or farmed

A paper published in Biology Methods and Protocols, finds that it is now possible to distinguish wild from farmed salmon using deep learning, potentially greatly improving strategies for environmental protection. The paper ...

Five ways to make the ocean economy more sustainable and just

The ocean has long been treated as boundless—a frontier for extraction and a sink for waste. This perception has driven decades of exploitation and neglect, pushing marine systems toward irreversible decline. Yet with urgent, ...
