Fish carcasses deliver toxic mercury pollution to the deepest ocean trenches

The sinking carcasses of fish from near-surface waters deliver toxic mercury pollution to the most remote and inaccessible parts of the world’s oceans, including the deepest spot of them all: the 36,000-foot-deep Mariana Trench in the northwest Pacific. And most of that mercury began its long journey to the deep-sea trenches as atmospheric emissions from […]

Fish give insight on sound sensitivity in autism

A tiny fish is helping scientists understand how the human brain processes sound, while also giving insight to autism spectrum disorder. Scientists at The University of Queensland used zebrafish that carry the same genetic mutations as humans with Fragile X syndrome and autism, and discovered the neural networks and pathways that produce the hypersensitivities to sound in […]

New insight into how future fish stocks are affected by phytoplankton and iron uptake

Research by the University of Liverpool sheds new light on the complex relationship between phytoplankton, iron uptake, global warming and fish stocks which is essential in helping policymakers develop effective conservation and fisheries management policies under climate change. Using a novel combination of ocean and ecosystem numerical models, researchers were able to demonstrate how changes […]

Hydroacoustic 3D snapshots of fish habitats could help stem overfishing

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 stocks to date – a key challenge in preventing exploitation of our marine ecosystems. ‘Fishers typically operate huge structures, like enormous nets, which are underwater where they […]
