The corpse of a humpback whale washed up on Ocean Shores Beach, Washington, on Aug. 11, possibly killed by getting wrapped up in fishing lines.
The whale had been floating offshore for a few days, monitored by scientists from the nonprofit Cascadia Research Center (CRC).
Commercial fishing gear is a deadly hazard for marine mammals. Fishermen leave lines and nets extending across miles of ocean, which whales cannot see. Whales become entangled and can drown, or can get deeply lacerated by the lines as they thrash in an effort to get free.
According to CRC researcher John Calambokidis, more than a dozen whales have died by entanglement so far this year.
Second Whale on Same Beach This Summer
A juvenile humpback washed up on the same beach on May 1—killed by getting tangled in the gear from a crab-fishing boat. That calf was 1–2 years old and about 28 feet long.Four other entanglements were reported in May—one other fatal.
When a whale survives entanglement, it is usually the work of teams from the National Oceanographic and Atmospheric Administration (NOAA) Large Whale Entanglement Response Network.
Deadly Entanglements
Unfortunately, despite the best efforts of rescue teams, most entanglements end up badly for the whales.Earlier that same month a gray whale died of entanglement and washed ashore on Long Beach Peninsula in southern Washington. That whale was caught in crab-fishing gear, some of which had wedged into its baleen, the filter plates in its mouth that strain out tiny mollusks that many whales feed on.
In May the CRC and SR3 in conjunction with NOAA and the Coast Guard, managed to remove some fishing line form a juvenile gray whale near La Push, Washington.
