Hydroacoustic 3D snapshots of fish habitats could help stem overfishing

Robotic eyes and ears under the water’s surface could help researchers figure out how much fish are in our oceans – and how much we can eat. Researchers are hoping fishing nets scanned by high resolution sonar, underwater cameras and unmanned aquatic vehicles can help paint one of the most accurate assessments of current fish … Read more

Marine scientists steer trawlers away from sensitive sea floors

Newly developed trawling gear can lower the impact of fishing on the sea floor.

Bottom trawling, where fishing boats drag a heavy net along the seafloor, can devastate marine habitats and cause fish stocks to plummet, but scientists have developed new eco-friendly techniques to support the sustainability of an industry employing tens of thousands of people. Bottom (benthic) trawling indiscriminately catches bottom-feeder fish and seafood like plaice, cod, shrimp, … Read more
