Increasing blanket of mucus-like substance in water threatens coral and fishing industry
King and snow crab populations in the Bering Sea have plummeted ahead of the harvest season, some by 99% compared to previous years.
This crab from the Pacific Ocean was once introduced into the Barents waters of the Soviet Union in Arctic Russia. Since then the invasive species has spread to Norway’s Barents Sea and a multi-million dollar industry has sprung up around it. In 2023 Norway exported 2,500 tons of king crab worth 1,2 billion kroner (€100 million).
Swarms of giant jellyfish are floating along the coastline of the Sea of Japan, and the damage they may cause to fisheries is feared to be the worst in more than a decade.
