November 06, 2018

This report provides a summary of large whale entanglements that occurred in U.S. waters in 2017 including species, locations, and an overview of response efforts.

Seventy-six confirmed cases of large whale entanglements were documented along the coasts of the United States in 2017. Seventy of these entanglement cases involved live animals and six involved dead animals. All were independently confirmed by the Large Whale Entanglement Response Network.

The five most frequently entangled large whale species in 2017 included humpback whale, gray whale, minke whale, blue whale, and North Atlantic right whale. Large whale entanglements were reported and confirmed in the waters of 13 states, along all U.S. coasts except within the Gulf of Mexico.

Approximately 70 percent of confirmed cases in 2017 were entangled in fishing gear (line and buoys, traps, monofilament line, and nets).
