Fish populations tend to do better in places where rigorous fisheries management practices are used, and the more measures employed, the better for fish populations and food production, according to a new paper published Jan. 11 in Nature Sustainability. The study, led by Michael Melnychuk of the University of Washington’s School of Aquatic and Fishery Sciences, draws upon the expertise of more than two dozen researchers from 17 regions around the world.

In pre-pandemic times, Seattle MESA coordinators Martha Flores Pérez and Brian Tracey could be found in six high schools and five middle schools in the Mukilteo, Seattle and Tukwila school districts, supplementing science and math classes with hands-on learning to expose students to the joys and excitement of STEM (science, technology, engineering and math). The goal of the program is to build a pipeline for students from communities that have been historically underrepresented in the sciences to pursue STEM in universities and professionally, and to help develop their identities as scientists.

Seafood is the world’s most highly traded food commodity, by value, and the product is hard to track from source to market. Reports of seafood mislabeling have increased over the past decade, but few studies have considered the overall environmental effects of this deceptive practice. A study by Arizona State University, the University of Washington and other institutions examined the impacts of seafood mislabeling on the marine environment, including population health, the effectiveness of fishery management and marine habitats and ecosystems.

Coral reefs serve important ecological functions, from providing habitat for countless species to protecting shorelines from erosion. Reef-dependent fisheries are also a vital source of food and income for hundreds of millions of people in tropical island nations where coral reefs are valued at $6.8 billion annually. The pressing concerns of climate change have placed the long-term health of the world’s coral reefs in jeopardy.
