West Coast whale entanglements reduced by half this season, but reason why is debated

September 13, 2019 — Whale entanglements involving fishing gear along the West Coast have dropped by more than 50% so far this year compared to 2018.

According to the National Oceanic and Atmospheric Administration as of Aug. 23, the National Marine Fisheries Service reported 17 confirmed whale entanglements in 2019, compared to 40 for the same period a year prior.

In both years, entanglements involved commercial Dungeness crab gear and drift gillnets.

“Year to date, it’s lower and is encouraging,” said Justin Viezbicke, NOAA’s West Coast Stranding coordinator. “We’ve seen spikes where we’ve seen seven or eight in a month and with three months left this year, things could still change.”

Feds declare emergency as gray whale deaths reach highest level in nearly 20 years

June 3, 2019 — Alarmed by the high number of gray whales that have been washing up dead on West Coast beaches this spring, the federal government on Friday declared the troubling trend a wildlife emergency.

The declaration by the National Oceanic and Atmospheric Administration technically, the agency dubbed the deaths an “unusual mortality event” kicks in a provision of federal law that provides funding for scientists to figure out the cause when such die-offs of marine mammals occur, from whales and dolphins in the Pacific or Atlantic to manatees off Florida.

So far this year, at least 70 gray whales have been found dead and stranded along the coasts of California, Oregon, Washington and Alaska the most in nearly 20 years, scientists from NOAA said Friday. In recent weeks, whales have washed up in Marin, San Francisco and San Mateo counties.

On average about 35 of the giant marine mammals wash up dead on the West Coast in a year, or around three per month. Last year, 45 were found.

But the average number found dead for the first five months of the year on the West Coast is 15, so this year is seeing five times the average rate.

“There have been juveniles but adults as well. There have been males and females. It’s been all across the board at this point,” said Justin Viezbicke, NOAA’s California Stranding Coordinator.

An Alarming Number of California Whales Are Getting Caught In Fishing Lines

California has seen a record-breaking number of whale entanglements over the last three years. Now, the Center for Biological Diversity is suing the state for failing to protect its endangered species.

August 30, 2017 — Justin Viezbicke once saw a whale struggling to swim up the coast of California without a tail. Though it was a disturbing sight, Viezbicke wasn’t exactly shocked; he’d encountered similar circumstances before. Viezbicke, the California stranding network coordinator for the National Oceanic and Atmospheric Administration, surmised that this particular whale’s flukes had been severed off by fishing gear. He knew the animal wouldn’t make it far.

In the past, Viezbicke has come across whales that lost blood-flow to their tails due to rope lines tangled tightly around their bodies. Less severe entanglements than the one Viezbicke witnessed can still lead to deadly infections or otherwise interfere with the animal’s ability to feed or forage.

“These entanglements are long, drawn-out processes,” Viezbicke says. “They can last months, sometimes even longer depending on the nature of the entanglement, and the will of the animal.”

The number of whales entangled in fishing lines off the West Coast of the United States has been sharply rising in recent years. In 2016, 71 whales became entangled in fishing gear off the West Coast, breaking the entanglement record for the third consecutive year. “We’re lucky if we get some or all of the gear off of a half dozen to a dozen of the whales every year,” Viezbicke says.

Entanglements are not always fatal, but for some threatened species, even a small number of deaths could be enough to collapse an entire population. (One subpopulation of humpback whales that feeds off the coast of California, for example, now numbers a mere 400.) Twenty-one endangered or threatened whales and one leatherback sea turtle were entangled in Dungeness crab gear in the Pacific Ocean in 2016; typically, Dungeness crab traps consist of a pot used to collect crabs on the seafloor, attached to a line of rope that extends to a buoy on the ocean surface.
