Regulatory News
February 2024 - NMFS Publishes its 2024 Five -Year review of
status of the NPRW under the Endangered Species Act
In February the National Marine Fisheries Service published
its 5-year
review of the North Pacific right whale (Eubalaena japonica)
under the Endangered Species Act (ESA) available at the link
above. I am in the process of digesting this 58 page report
and reporting more information about its contents and analysis.
Findings in the Report:
- The NPRW should remain classified as Endangered under
the Endangered Species Act
- The NPRW's "Recovery Priority Number" under the ESA
should be changed from 4C to 5C "largely based on the high
demographic risk to the species (sue to the small size of
eastern population) and a low understanding of major threats to
the species and how effective management actions may be in
addressing these threats. There is also potential conflict (5C)
for this species due to overlap major shipping routes and oil
and gas activities in Alaskan waters."
"RECOMMENDATIONS FOR FUTURE ACTIONS
As there is still so much unknown about the eastern North
Pacific right whale population, the most urgent need is better
information on basic distribution and phenology, including
identification of wintering areas, spatio-temporal overlap with
and impacts of the shipping and fishing industries, and
identification and management of emerging threats to the
population. In order to be able to inform management and
conservation of this extremely rare and endangered stock, we
recommend the following actions be taken or initiated over the
next five years:
- Conduct a risk analysis to understand what geographic areas
and activities post a particularly high risk of further impeding
recovery of North Pacific right whales.
- Use of autonomous underwater recording devices should be
continued and expanded, with additional passive acoustic
moorings deployed in the eastern Gulf of Alaska, in Aleutian
Island passes, in Bristol Bay, and in the Northern Bering Sea to
provide more extensive coverage of areas known to be used by
North Pacific right whales, possible migratory pathways, and
northward expansions of habitat.
- Biopsy sampling should continue to be a priority; data from
these samples can inform sex ratios, abundance estimates, stress
hormone levels, reproductive status, and feeding strategies
through stable isotope analysis.
- Conduct annual vessel-based surveys, augmented by passive
acoustic techniques, to assess North Pacific right whale
distribution in key areas. This action will enable the following
3 actions below.
- Deploy satellite tags on North Pacific right whales to improve
understanding of movements, habitat use, and migration.
- Conduct biopsy sampling to understand genetics and stock
structure, reproductive status, sex, feeding strategies, and
facilitate estimation of abundance.
- Collect data on prey availability and quality to enable
synthesis of prey data with acoustic and visual sighting
information to better understand the impacts of shifting prey
regimes on habitat quality and location.
- Develop the use of satellite imagery to understand North
Pacific right whales occurrence.
- Develop other advanced technologies such as ‘omics, AI/ML, and
UxS (both underwater and aerial) to understand North Pacific
right whale distribution and abundance.
- Raise awareness about North Pacific right whales
throughout their range (e.g., Alaska, British Columbia, west
coast of the United States, Baja Mexico, Pacific Islands), to
increase reporting of opportunistic sightings and encourage
public stewardship."

2024 - New law review article on North Pacific Right Whales:
Elza Bouhassira, Among
the Rarest: Saving the Eastern North Pacific Right Whale, 40
Alaska Law Review 189-224 (2024)
"This note aims to highlight the crisis facing eastern NPRWs and
the steps that can be taken to support the recovery of this rare
whale. The paper first presents information on the history of the
species and its importance. It next examines existing
international and domestic U.S. legal regimes as well as a pending
petition to revise NPRW critical habitat off of Alaska. Finally,
it advances six recommendations to support the eastern NPRW's
recovery: (1) more data collection should be facilitated; (2) the
precarious situation of the NPRW should be shared to raise public
awareness and support for protection measures; (3) the critical
habitat designation should be expanded, but to a lesser extent
than the petition has requested*; (4) a whale-ship interaction
risk reduction regime should be adopted; (5) whale-friendly
fishing gear should be widely adopted; and (6) commercial whaling
must remain illegal. It argues that with the right protections,
eastern NPRWs can avoid extinction.
* The author recommends that the critical habitat expansion
should be limited to areas around Unimak Pass and the western part
of Kodiak Island as shown in the map below:

September 25, 2023 - NOAA Issued its "12-Month Finding" on
the petition filed by the Center for Biological Diversity (March
10, 2022) advocating a revision to the designated NPRW's Critical
Habitat based on new information. CBD's petition
requests NOAA revise the critical habitat to connect the two
existing critical habitat areas. This would entail extending the
Southeast Bering Sea boundary west and south to the Fox Islands,
through Unimak Pass to the edge of the continental slope. It
would also extend east to the Gulf of Alaska critical habitat
area off the coast of Kodiak Island. NOAA states that it has not
yet decided whether to propose the specific revision recommended
by the petitioners or some other revision to the critical
habitat designation."
"New
information has been collected since critical habitat was
initially designated in 2008. It provides a better understanding
of North Pacific right whale movements and habitat use.
North
Pacific right whales have been detected in and around currently
designated critical habitat. Acoustic moorings detected North
Pacific right whale calls across all years and seasons from 2009
to 2015 in Unimak Pass in the Aleutian Islands, which is not
currently designated critical habitat.
North
Pacific right whales were seen for the first time during winter
just outside Unimak Pass in
February 2022. Four North Pacific right whales were seen in the
Gulf of Alaska in August 2021. One pair was actively feeding in
the currently designated critical habitat area off Kodiak Island
and the second pair was outside of critical habitat, about 100
miles to the west of where the first pair was sighted.
In
it September 2023 Notice, NOAA
described its intent to proceed with a preparing a formal
revision, without committing to the specific revisions proposed
by CBD..
NOAA's 12 Month finding on CBD's Petition appears in the
Federal Register on September 26, 2023 (citation: 88 FR 65940 and
available
on-line here). To identify what areas qualify as
critical habitat for this species, NOAA proposes to conduct
an analysis and synthesis of:
- Available
acoustic mooring data
- Visual
sightings
- Observations
of right whale feeding behavior
- Spatial
and temporal patterns in right whale prey
NOAA
will also consider potential economic, national security, and any
other relevant impact of designating any particular areas as
critical habitat.
Based on the data supporting critical habitat, NOAA will then propse
a revision of the critical habitat. NOAA will develop a proposed
rule that will undergo public comment and a final rule that
addresses information and comments received during the comment
period.

NOAA's policy on U.S. North Pacific Right whales remains the
policy described in NMFS'
Final Recovery Plan for the North Pacific Right Whale (Eubalaena
japonica) issued June 3, 2013
pursuant to the Endangered Species Act.The Recovery Plan contains
a good description of the current scientific knowledge in 2013
regarding the threats the species faces and what NOAA plans
to do to prevent the species from going extinct.

Recent Sightings:
On 24 May 2024. One North Pacific Right Whale "was
observed for 20 minutes" milling west of Pt. Reyes, California
over the Cordell Bank National Marine Sanctuary as
reported by ACCESS Oceans on its Facebook page.
The
observations were made by the Applied California Current Ecosystem
Studies a partnership between Greater Farallones and Cordell Bank
National Marine Sanctuaries and Point Blue Conservation Science.
The observations were made onboard the NOAA Ship Bell
M Shimada Two photos are posted on that Facebook page
and the photos and videos have been sent to NOAA's Marine Mammal
Lab in Seattle. More details will be provided as they are learned.
On 5 March 2023 one North Pacific Right whale was
seen at 9:47 am close to shore near
Pt.
Pinos, Monterey Bay, California by multiple observers
on a Monterey Bay Whale Watch whalewatching cruise. The whale was
heading west. Contact with the whale was lost after 15 minutes due
to sea conditions. This whale was also seen by crew and passengers
on the Princess Monterey Whalewatch boat that was on a whale
watching cruise. There are numerous photos taken that clearly show
the animal was a right whale. Of note is that the whale had dozens
of barnacles on its back and lips in addition to the callosities.
The March date and the presence of coronulid barnacles parallels
the sighting off Half Moon Bay in 1982.
On 19 April 2022 one North Pacific Right Whale was
seen around 9:00 am at 37° 06.029 N, 122° 26.003 W) 5.3
miles southwest of Point Ano Nuevo, California. The whale was
spotted by a recreational fisherman named Jack Gross. The
whale was photographed and a short video taken, now in possession
of NOAA which confirm its identity as a right whale. It appeared
to be feeding by skimming the surface while swimming. (pers.
comm from William Douros, NOAA)
On February 11, 2022,
two North Pacific Right Whales were seen and photographed in the
Bering Sea, the first right whales seen in the Bering Sea in
winter.
May 26, 2020, 1 North Pacific Right whale seen approximately 20
nm west of ____/Brooks Peninsula, Vancouver Island during a
transit to Anchorage. Richard Goings made the sighting and has a
29 second video which has been posted to Facebook. (awaiting more
detailed info)
15
North Pacific Right Whales were seen in the eastern Bering Sea during
summer 2017 on the International Whaling Commission/Japan POWER
cruise in the eastern Bering Sea. Photographs were obtained of
12 of these whales and biopsy dart samples from 3.
In August 2015, NOAA Fisheries conducted a
three week dedicated ship survey for North Pacific right
whales in the Gulf of Alaska southeast of Kodiak Island covering
2,500 nautical miles with both visual observers and acoustic
detection devices (sonobuoys). On
March 10 and March 16 they heard calls from a single right whale
in the area of Barnabas Trough southeast of Kodiak Island in the
general area of the designated Critical Habitat. Despite intensive
searching, they were unable to spot the animals visually.
Wikipedia & this webpage - how are they different?
In 2010, I decided to change the focus of the present webpage
from being a primary source of all information about this species
to being a complement to Wikipedia's
North Pacific Right Whale page. So, with the help
of many others, I added large amounts of information to the
Wikipedia article.
The advantages of this approach is that Wikipedia has many more
visitors and collaborative help from others. Wikipedia is a
know, and generally well trusted website, and it attracts many
viewers who would not wander to a specialized site like mine.
How do the websites differ?
- Wikipedia
- Best initial source of general information about the
biology, legal status, conservation, and whaling history
regarding this species.
- All information is "factual" and "verifiable" through the
inclusion of references
- The material is condesnsed as appropriate for an
encyclopedia article - albeit a 24 page encyclopedia
article!
- (note that Wikipedia has separate articles for the genus Eubalanea
(Right
Whale), the North
Atlantic Right Whale, and the Southern
Right Whale. Much of the information on
these other pages also applies to the North Pacific species.
- This Webpage:
- In general, this website can host much more detailed
information about select subjects, including:
- News about North Pacific Right Whale biology and
conservation that has not made it into Wikipedia
- tools to help scientists and other researchers,
specifically:
- annotated bibliography
of papers and books on right whales (I believe this is
the most complete bibliography of recent papers
available)
- abstracts of scientific
articles that are not available on-line
- hosting of several papers otherwise not available
on-line
- detailed listing of all sightings of right whales
along the coasts of
- California, Oregon, Washington and Baja
- This webpage can contain discussion about various
conservation threats and proposals and opportunities to
address them.
- Recommended list of popular books and articles about the
North Pacific Right Whale
- Gallery of Photos and art associated with North Pacific
Right Whales
- list of conservation organizations involved in right whale
conservation
Many people know of right whales as a consequence of Roger
Payne's National Geographic Society TV specials on the whales
of Peninsula Valdez, Argentina. Right whales have also
recently gotten attention from whale-watchers off Cape Cod and
other areas in the northeast and eastern Canada. Right whales
are even becoming the object of significant whale watching
industries (and nice WWW sites!) along the coasts of
Australia (Whales
on the Net and (South
Australia Whale Centre), South
Africa, and New
Brunswick, Canada. However, right whales also occur in
the North Pacific. In fact, they were the basis for a major
whaling industry in the North Pacific, particularly between
1840-48. They still occur in the North Pacific, yet they are
the forgotten whale species. Here is some information about
them.
The World's Most Endangered Whale Species: The North Pacific
Right Whale
Among the large whales, right
whales have shown the least signs of recovery after their
decimation by whalers. The population in the eastern North
Atlantic that supported a major fishery appears to be zero.
The population in the western North Atlantic is less than 400
animals. In the North Pacific, the species is so exceedingly
rare that almost every sighting of a single animal is a
publishable event. There may only be a few hundred animals or
less in the entire North Pacific with most of these animals
occurring in the western North Atlantic and the Sea of
Okhotsk.
In the U.S., conservation of
all whales is the responsibility of the National Marine
Fisheries Service (NMFS) in the Department of Commerce. Their
WWW site has information about North
Pacific Right Whales generally. Pursuant to its
responsibilities under the Endangered Species Act and the Marine
Mammal Protection Act, in 1990 NMFS prepared a Recovery
Plan for the Northern Right Whale which it is now
updating. Because the western North Atlantic population is
much better known than the No Pacific population, the former
has been the focus of the conservation efforts of NMFS and
other groups such as the New
England Aquarium and the Center for Coastal Studies in
Provincetown, MA. The North Pacific right whale
population remains elusively difficult to study, let alone
protect. The International Whaling Commission convened a
Special Meeting of the Scientific Committee to Review the
Status of Right Whales in March 1998 in South Africa.
-
My studies of Maury's whaling records from the 1840s revealed
very dense populations of right whales both in the Gulf of
Alaska, and more particularly along the coast of Kamchatka
(RWs seen on 90+% of search days) and along the Kurile
Islands. Review of the historic whaling records shows an
extraordinary abundance of right whales in the North Pacific
in the 1840s. Right whales appear to have been more abundant
than gray whales in the North Pacific. I hope that the No Pac.
right whale is not forgotten in all the justified concern for
RWs in other oceans.
All indications are that the E North Pacific population is
exceedingly small and may be on its way out. Given the level
of whalewatching/fishing/pelagic birding effort along the
California coast, particularly during the January-March
period, the low level of sightings appears to mirror a very
small, perhaps intermittent population here.
