Fishermen, communities need more than healthy fish stocks

Aquatic and Fishery Sciences’ Chris Anderson and a team of scientists have developed a new assessment that looks at fisheries’ economic and community benefits, as well as ecological health. Anderson and his team created new ways of measuring three performance indicators – ecology, economics, and community – all of which can be applied across species, management approaches, and nations. To characterize a fishery, the authors drew on local experts’ knowledge, scoring each response and averaging them in each category.

Sustainability progress should precede seafood market access, researchers urge

A fish market in the Solomon Islands, near Papua New Guinea.

A team of researchers, including Edward Allison from the College of the Environment’s School of Marine and Environmental Affairs, has evaluated fishery improvement projects designed to bring seafood from wild fisheries to the certified market while promising sustainability in the future. In a policy paper appearing May 1 in Science, the team concluded that these projects need to be fine tuned to ensure that fisheries are delivering on their promises.

New research suggests forage fish populations negatively impacted by fisheries

A new study by Tim Essington, Aquatic and Fishery Sciences, shows for the first time that fishing likely worsens population collapses in several species of forage fish, including herring, anchovies, and sardines. Some of the largest fisheries in the world target these species, which are also a key food source for larger marine animals like salmon, tuna, seabirds, and whales. Previously, it wasn’t known whether population collapses and other population shifts in forage fish were naturally-occurring or related to fishing.

Beyond ecology: Invasive species affect our culture and economy too

Swing, batter! On a residential street in Anywhere, U.S.A., a colony of invasive emerald ash borers swarms inconspicuously on the periphery. Their sights are set on a row of lush, mature ash trees that line the quiet street. These trees have seen their community through World War II and the Civil Rights Movement, but meeting the ash borers will mark their final stand.

Kill two birds with one dead tree? Beetle-killed pines could fuel machines instead of fires

Across western North America you can see them: hills blanketed with swaths of red and gray trees. These dead and dying stands of pine, aspen, and fir, totaling around 42 million acres—roughly the size of the state of Washington—are victims of bark beetles. And the dry, decaying trees that the beetles leave in their wake are not just eyesores; they also fuel hotter and larger wildfires.
