Scientists discovered over nine billion juvenile polar cod living under Arctic sea ice using specialized nets. These fish, vital to the Arctic food web, likely drift from Siberian spawning grounds. Their role may grow as warming seas shrink other populations.

The 50th European Marine Biology Symposium (Sept 21–25, 2015) returns to Helgoland, where it began in 1966. Around 200 researchers discuss long-term environmental data, climate change impacts, algal blooms, invasive species, and marine ecosystem shifts.

Micro-plastic particles in edible fish and herbivores

AWI studies reveal microplastic ingestion in mackerel and periwinkles. Mackerel mistake fibers for prey, while periwinkles eat particles stuck to algae. Both groups ingest microplastics, but health effects remain unclear, especially with long-term exposure.
