Adventure Rib Rides saw its first whale off the coast this past weekend marking the start of the summer whale watching season. The whale population in San Diego is growing, and people coming on the tour are more and more likely to see these beautiful whales as they swim around in their families.
If your bucket list includes seeing the world's largest animal, it's time to check the box.
Adventure Rib Rides,
a local ocean tour company, reported its first blue whale sightings of
the year off the San Diego coast over the holiday weekend, launching the
summer viewing season. Capt. Ken Manzoni found four blues about four
miles offshore of Point Loma on Saturday.
The
company said 2011 was a banner year for blues because San Diego hosted
five pods of blues during the summer and fall and passengers commonly
saw more than 20 in a trip. In all, Manzoni figures about 50 blues made
San Diego their summer home last year and a few thousand pass through
local waters on their way elsewhere.
"Our
local population does appear to be growing and growing," Manzoni said.
"By mid-June, that is when we generally will have a good couple dozen
that will set up shop."
He
said he recognizes some of the blues by sight and can track their ocean
wanderings close enough to often predict where they will surface to
gorge on shrimp-like krill.
Southern
California has become a top spot to see blue whales, which can be
spotted in local waters into the fall. They are the largest creatures
known to have lived on Earth; they can weigh more than 300,000 pounds
and grow more than 100 feet long.
Based
on acoustic and whaling data, federal fisheries officials believe the
eastern Pacific stock of blues winters off Mexico, Central America and
elsewhere. It feeds during summer off the West Coast and to a lesser
extent in the Gulf of Alaska.
NOAA
estimates blue whale abundance in the eastern Pacific is about 1,700,
and the agency said the population has been increasing over the past two
decades off the California coast.
"The
magnitude of this apparent increase is too large to be accounted for by
population growth alone and, therefore, it is assumed that a shift in
distribution has occurred," said the agency's web site. "Although the
population in the North Pacific is expected to have grown since
protection began in 1966, the possibility of continued unauthorized
takes, incidental ship strikes and mortality, and serious injury in
fishing gear makes this uncertain. Also, the evident scarcity of blue
whales in areas of former abundance (e.g., Gulf of Alaska and near the
Aleutian Islands) suggests that the increasing trend does not apply to
the species' entire range in the eastern North Pacific."
The San Diego Natural History Museum starts offering blue whale sightseeing cruises on June 17.
In Orange County, Newport Landing Whale Watching has documented eight of the giant creatures this year.
For those interested in venturing farther afield, the American Cetacean Society's Los Angeles Chapter is planning a daylong "Summertime Blues" tour out of Santa Barbara on June 30.
Of
course, there's no guarantee that blue whales will show up on any given
day, but tour operators said fin whales, minke whales and dolphins are
regularly spotted this time of year.
