Gray whale sets time record in San Francisco Bay



According to the Marine Mammal Center, a gray whale has been in the San Francisco Bay since early February, a record amount of time that could put the animal at risk of being hit by a ship.

According to Bill Keener of the marine mammal conservation biology group at the Marine Mammal Center, a nonprofit rescue organization, the whale, which arrived on February 9, was discovered on Monday. – 75 days later – by a team on a boat. The previous record for a gray whale in the bay was 46 days.

“We were able to recognize pigment patterns in whales. You can tell them apart if you look closely enough,” he said. “This whale has been here for two and a half months. That’s a record for us — we’ve never seen anyone stay that long before.”

According to Keener, in a typical year, San Francisco Bay has one or two gray whales that stay for a day or two. Whales breed in lagoons in Mexico and migrate to Alaska to feed, sometimes stopping in bays along the way.

The waters in San Francisco Bay are very calm, and whales sometimes linger to eat and rest.

Starting in 2019, many gray whales were seen stopping in the bay and some washed ashoreled the National Oceanic and Atmospheric Administration to declare an “unusual fatal event”.

So far during this migration season, eight gray whales and one humpback whale have been spotted in the bay, raising concern among scientists who fear the animals could be hit by ships in the water. context of heavy maritime traffic between Oakland and San Francisco.

“We have a complicated story about whales coming to the bay, which is their refuge, but that creates a conservation concern for us, because it’s a busy port and it’s a big deal,” says Kenner. There is a possibility of a collision with a vessel. “That’s why we’re monitoring all these whales in the bay and trying to keep them safe.”

ONE 35-foot gray washed up on March 23 on Bolinas Beach, east of Duxbury Point, in Marin County – the first whale fatality in the area this year. Scientists from the Marine Mammal Center conducted an autopsy and concluded that the whale likely died from its injuries after crashing into the boat.

Humpbacks started arriving in the bay in 2016, when warming oceans resulted in fewer krill, the animals’ main food source, which thrive in cold waters. Instead, the whales started coming closer to the shore to eat the anchovies.

“Over the past decade, the bay has really been cleaned up,” says Keener. “I’ve never seen a whale use the bay, and now we see humpback whales coming here every year.”

Keener encourages residents report marine mammals they discovered.

“We can’t always keep an eye on the water,” he said, noting that reports from residents have come in. “It’s a huge area.”
