May 5, 2021 — The following was released by NOAA Fisheries:
NOAA scientists have combined the latest data on ocean conditions and marine life off the West Coast on a new data tool. It gives fishermen and fishery managers up-to-date ecosystem information that may help reduce the risk of whale entanglements. They hope it will also help the public understand how environmental factors influence the marine food web in a time of climate change.
“Resource managers and stakeholders can refer to the page for the latest information like prey abundance or sea surface temperatures before considering a season delay or other management options,” said Jarrod Santora, a research biologist at the NOAA Fisheries Southwest Fisheries Science Center who helped develop the new system.
Increase in Whale Entanglements
Between 2014 and 2019, NOAA Fisheries confirmed 163 large whale entanglements off Washington, Oregon, and California. By comparison, 64 whale entanglements were confirmed in the same region from 2008 to 2013. Humpback whales are the most common species entangled, but NOAA also confirmed gray, blue, fin, and minke whales entanglements. NOAA is responsible for recovering and protecting these whales under the Endangered Species Act and Marine Mammal Protection Act.
