‘Safety in numbers’ tactic keeps Pacific salmon safe from predators

fish swim together in a fish tank

A new University of Washington study that leverages historical data has found unique support for a “safety in numbers” hypothesis by showing that Pacific salmon in larger groups have lower risk of being eaten by predators. But for some salmon species, schooling comes at the cost of competition for food, and those fish may trade safety for a meal.

eDNA a useful tool for early detection of invasive green crab

green crab in the mud

As the green crab invasion in the state worsens, a new analysis method developed by University of Washington and Washington Sea Grant scientists could help contain future invasions and prevent new outbreaks using water testing and genetic analysis. The results show that the DNA-based technique works as well in detecting the presence of green crabs as setting traps to catch the live animals, which is a more laborious process. Results suggest these two methods could complement each other as approaches to learn where the species’ range is expanding.

Shifting ocean closures best way to protect animals from accidental catch

turtle swims in the ocean

Many nations are calling for protection of 30% of the world’s oceans by 2030 from some or all types of exploitation, including fishing. Building off this proposal, a new analysis led by the University of Washington looks at how effective fishing closures are at reducing accidental catch. Researchers found that permanent marine protected areas are a relatively inefficient way to protect marine biodiversity that is accidentally caught in fisheries. Dynamic ocean management — changing the pattern of closures as accidental catch hotspots shift — is much more effective.
