SUPPLEMENTARY INFORMATION:
Background
Section 117 of the Marine Mammal Protection Act (MMPA) (16 U.S.C.
1361 et seq.) requires NMFS and the U.S. Fish and Wildlife Service
(FWS) to prepare stock assessments for each stock of marine mammals
occurring in waters under the jurisdiction of the United States,
including the Exclusive Economic Zone. These reports must contain
information regarding the distribution and abundance of the stock,
population growth rates and trends, estimates of annual human-caused
mortality and serious injury (M/SI) from all sources, descriptions of
the fisheries with which the stock interacts, and the status of the
stock. Initial reports were completed in 1995.
The MMPA requires NMFS and FWS to review the SARs at least annually
for
[[Page 47132]]
strategic stocks and stocks for which significant new information is
available, and at least once every three years for non-strategic
stocks. The term ``strategic stock'' means a marine mammal stock: (A)
For which the level of direct human-caused mortality exceeds the
potential biological removal level or PBR (defined by the MMPA as the
maximum number of animals, not including natural mortalities, that may
be removed from a marine mammal stock while allowing that stock to
reach or maintain its optimum sustainable population); (B) which, based
on the best available scientific information, is declining and is
likely to be listed as a threatened species under the Endangered
Species Act (ESA) within the foreseeable future; or (C) which is listed
as a threatened species or endangered species under the ESA. NMFS and
the FWS are required to revise a SAR if the status of the stock has
changed or can be more accurately determined.
Prior to public review, the updated SARs under NMFS' jurisdiction
are peer-reviewed within NMFS Fisheries Science Centers and by members
of three regional independent Scientific Review Groups, which were
established under the MMPA to independently advise NMFS on information
and uncertainties related to the status of marine mammals.
The period covered by the 2018 draft SARs is 2012-2016. NMFS
reviewed the status of marine mammal stocks as required and revised a
total of 47 reports representing 76 stocks in the Alaska, Atlantic, and
Pacific regions to incorporate new information. The 2018 revisions
consist primarily of updated or revised M/SI estimates and updated
abundance estimates. One stock (Alaska bearded seal) changed in status
from non-strategic to strategic, and three stocks (Gulf of Maine
humpback whale, and Western North Atlantic short-finned and long-finned
pilot whales) changed in status from strategic to non-strategic.
Substantive revisions to the SARs are discussed below. NMFS solicits
public comments on the draft 2018 SARs.
Alaska Reports
In 2018, NMFS reviewed all 45 stocks in the Alaska region, and
revised SARs under NMFS jurisdiction for 18 stocks (14 strategic and 4
non-strategic). The Alaska bearded seal stock changed from ``non-
strategic'' to ``strategic'' status because the stock is now considered
depleted under the MMPA (see below). A list of the 18 reports revised
in 2018 for stocks in the Alaska region is presented in Table 1.
Information on the remaining Alaska region stocks can be found in the
final 2017 reports (Muto et al., 2018).

Revisions to the Alaska SARs included updates of abundance and/or
M/SI estimates, including revised abundance estimates for Western U.S.
Steller sea lion; Eastern Pacific northern fur seal; and Cook Inlet
beluga whale.
Alaska Bearded Seal
In 2012, NMFS listed the Beringia distinct population segment of
bearded seal, and thus the Alaska stock of bearded seal, as threatened
under the ESA (77 FR 76740, December 28, 2012). The primary concern for
this population is the ongoing and projected loss of sea-ice cover
stemming from climate change, which is expected to pose a significant
threat to the persistence of these seals in the foreseeable future. In
2014, the U.S. District Court for the District of Alaska issued a
decision vacating NMFS' listing in a lawsuit that challenged listing
bearded seals under the ESA (Alaska Oil and Gas Association v.
Pritzker, Case No. 4:13-cv-00018-RPB). Consequently, it was also no
longer designated as ``depleted'' or classified as a strategic stock.
In 2016, the 9th Circuit Court of Appeals overturned the decision and
approved the agency's protection of the seals; and in 2018, the U.S.
Supreme Court declined a challenge to NMFS' listing decision. Thus,
because of its threatened status under the ESA, this bearded seal stock
is considered depleted under the Marine Mammal Protection Act andis now
classified as a ``strategic'' stock.
Atlantic Reports
In 2018, NMFS reviewed all 117 stocks in the Atlantic region
(including the Atlantic Ocean, Gulf of Mexico, and U.S. territories in
the Caribbean) under NMFS jurisdiction. This year, NMFS revised 16
reports and created 2 new common bottlenose dolphin reports (West Bay
and Terrebonne Bay/Timbalier Bay). These updated reports represent 42
stocks (26 strategic and 16 non-strategic). The Gulf of Maine humpback
whale stock and Western North Atlantic (WNA) long-finned and short-
finned pilot whale stocks changed from ``strategic'' to ``non-
strategic'' status because the mean annual human-caused M/SI is below
PBR (see below). A list of the 42 stocks in the Atlantic region
(contained in 18 reports), is presented in Table 2. Information on the
remaining Atlantic region stocks can be found in the final 2017 reports
(Hayes et al., 2018).

* Details for these 25 stocks are included in the report: Common
bottlenose dolphin, Northern Gulf of Mexico Bay, Sound, and Estuary
Stocks.
Revisions to the Atlantic SARs included updates of abundance and/or
M/SI estimates. New abundance estimates are available for the North
Atlantic right whale, Gulf of Maine humpback whale, WNA short-finned
pilot whale, WNA rough-toothed dolphin, and the West Bay and Terrebonne
Bay/Timbalier Bay common bottlenose dolphin stocks.
North Atlantic Right Whale, Western Atlantic
Although PBR analyses in this 2018 SAR reflect data collected
through 2016, it should be noted that an additional 17 North Atlantic
right whale mortalities were observed in 2017 (Daoust et al. 2017).
This number exceeds the largest estimated mortality rate during the
past 25 years. Further, despite the usual extensive survey effort, only
5 and 0 new calves were detected in 2017 and 2018, respectively.
Therefore, the decline in the right whale population is expected to
continue for at least an additional 2 years. The minimum population
size for the Western Atlantic stock of the North Atlantic right whale
is 445 and PBR is 0.9.
Humpback Whale, Gulf of Maine
The updated abundance estimate for the Gulf of Maine humpback whale
stock is 896, based on a recent count of the minimum number alive
(MNA). The 2015 humpback whale MNA was produced by counting the number
of unique individuals seen in 2015 in the Gulf of Maine stock area as
well as seen both before and after 2015. The 2015 humpback whale MNA
includes not only cataloged whales but some calves born in 2015 but not
yet identifiable. MNA is a rigorous accounting of individuals and has
no associated coefficient of variation (CV). It is both more recent and
larger than the previous 2011 line transect estimate of 335 and has
zero probability of overestimating abundance. Although the abundance
appears to increase from 2017 to 2018, these estimates should not be
compared as they were derived using different methodologies and data
sets. As a result of the higher abundance estimate, the PBR for the
Gulf of Maine humpback whale stock increased from 3.7 to 14.6 whales.
Based on a recovery factor of 0.5, the estimate of human-caused M/SI is
now below PBR; thus, the stock has changed from ``strategic'' to ``non-
strategic.''
Long-Finned Pilot Whale, Western North Atlantic
The PBR for the western North Atlantic long-finned pilot whale is
35 and the estimate of total annual observed average fishery-related of
human-caused M/SI is 27. In bottom trawls and mid-water trawls and in
the gillnet fisheries, mortalities were more generally observed north
of 40[deg] N latitude and in areas expected to have only long-finned
pilot whales. Takes in these fisheries were therefore attributed to the
long-finned pilot whales. Takes in the pelagic longline fishery were
partitioned according to a logistic regression model (Garrison and
Rosel 2017). Because the M/SI does not exceed PBR, the stock has
changed from ``strategic'' to ``non-strategic.''
Short-Finned Pilot Whale, Western North Atlantic
The best available abundance estimate for short-finned pilot
whales, based on shipboard surveys conducted during the summer of 2016
in the western North Atlantic, is 28,924. These most recent surveys
covered the full range of short-finned pilot whales in U.S. Atlantic
waters. Because long-finned and short-finned pilot whales are difficult
to distinguish at sea, sightings data are reported as Globicephala sp.
These survey data have been combined with an analysis of the spatial
distribution of the two pilot whale species based on genetic analyses
of biopsy samples to derive separate abundance estimates for each
species. Due to changes in survey methodology, previous abundance
[[Page 47134]]
estimates should not be used to make comparisons with more current
estimates. As a result of the higher abundance estimate, the PBR for
the western North Atlantic short-finned pilot whale increased from 159
to 236 and the estimate of total annual observed average fishery-
related of human-caused M/SI is 27. The estimate of human-caused M/SI
is now below PBR; thus, the stock has changed from ``strategic'' to
``non-strategic.''
Common Bottlenose Dolphins
NMFS is in the process of writing individual stock assessment
reports for each of the 31 bay, sound, and estuary stocks of common
bottlenose dolphins in the northern Gulf of Mexico. Two new individual
reports, for the West Bay and Terrebonne-Timbalier Bay Estuarine System
stocks, were completed for the draft 2018 SARs. Therefore, the reader
will not see tracked changes in the draft 2018 reports for these
stocks. To date, six bottlenose dolphin stocks have individual reports
completed (West Bay, Terrebonne-Timbalier Bay Estuarine System,
Barataria Bay Estuarine System, Mississippi Sound/Lake Borgne/Bay
Boudreau, Choctawhatchee Bay, and St. Joseph Bay), and the remaining 25
stocks are included in the Northern Gulf of Mexico Bay, Sound, and
Estuary Stocks report.
Pacific Reports
In 2018, NMFS reviewed all 87 stocks in the Pacific region (waters
along the west coast of the United States, within waters surrounding
the main and Northwestern Hawaiian Islands, and within waters
surrounding U.S. territories in the Western Pacific), and revised SARs
for 16 stocks (7 strategic and 9 non-strategic). A list of the reports
revised in 2018, representing 16 stocks in the Pacific region, is
presented in Table 3. Information on the remaining Pacific region
stocks can be found in the final 2017 reports (Carretta et al., 2018).

lions, Hawaiian monk seals, Eastern North Pacific Offshore killer
whales, Southern Resident killer whales, Eastern North Pacific gray
whales, Western North Pacific gray whales, California/Oregon/Washington
humpback whales, and Hawaii Island spinner dolphins.
New Methodology To Estimate Level of Vessel Strike Mortality: CA/OR/WA
Humpback Whale, CA/OR/WA Fin Whale, and the Eastern North Pacific Blue
Whales
New information on serious injury and mortality resulting from
estimated vessel strikes based on an analysis by Rockwood et al. (2017)
is included for the following stocks of large whales: CA/OR/WA humpback
whale, CA/OR/WA fin whale, and the Eastern North Pacific blue whales.
Using the moderate level of vessel avoidance, this model estimated the
following annual mortality of these stocks of large whales due to ship
strikes as follows: 22 humpback whales (representing approximately 0.7
percent of the estimated population size of the stock); 43 fin whales
(representing approximately <0.5 percent of the estimated population
size of the stock); and 18 blue whales (representing approximately 1
percent of the estimated population size of the stock. Based on this
new methodology, estimated levels of vessel strike mortality exceed PBR
for both Eastern North Pacific blue and CA/OR/WA humpback whale stocks,
although estimated vessel strike levels represent a small fraction of
the overall estimated population sizes. Estimated vessel strikes are
also compared with recent detected levels of vessel strikes, which
indicate that detection rates for vessel strike events are quite low,
ranging from approximately 1 percent (for blue whales) to 12 percent
(for humpback whales). There is uncertainty regarding the estimated
number of ship strike deaths as carcass recovery rates are quite low.
New Methodology To Assign Cases of Entangled but Unidentified Whales to
Stock: CA/OR/WA Humpback Whale, CA/OR/WA Fin Whale, Eastern North
Pacific Gray Whale, and Eastern North Pacific Blue Whales
Unidentified whales represent approximately 15 percent of
entanglement cases along the U.S. West Coast. In previous stock
assessments, unidentified entanglements were not assigned to stock. For
large whale stocks, including gray, humpback, blue, and fin whales, a
new methodology based on an assignment model generated from historic
known-species entanglements in the region was used to assign previous
cases of unidentified whale entanglements to species (Carretta 2018).
This has eliminated a negative bias in assessments that occurs when
unidentified whale entanglements are not assigned to any species/stock.
In the case of CA/OR/WA humpback whales, observed levels of
entanglements and vessel strikes combined exceed PBR.
New Methodology To Calculate the Minimum Population Estimate (Nmin) for
California Sea Lion
The 2018 SAR for California sea lions uses a different methodology
for estimating Nmin. The updated minimum population size of the U.S.
stock is 233,515 (153,337 in 2014 SAR). This resulted in an increase in
PBR from 9,200 (in 2014) to 14,011. The updated best abundance estimate
available for California sea lions, based on a 1975-2014 time series of
pup counts, combined with mark-recapture estimates of survival rates,
is 257,606 sea lions (Laake et al., 2018) (down from 296,750 in 2014
SAR).
The previous approach to calculate Nmin used two times the annual
pup
[[Page 47135]]
count, which resulted in negatively-biased Nmin values because not all
age classes are represented. The Guidelines for preparing Stock
Assessment Reports (NMFS 2016) recommends defining Nmin as the 20th
percentile of a log-normal distribution based on an estimate of the
number of animals in a stock (which is equivalent to the lower limit of
a 60% 2-tailed confidence interval). The Guidelines allow for other
approaches to be used to estimate Nmin if they provide an adequate
level of assurance that the stock size is equal to or greater than that
estimate. Laake et al. (2018) did not provide a CV for the estimated
population size, so the updated Nmin is based on the lower 95 percent
confidence limit. The stock is estimated to be approximately 40 percent
above its maximum net productivity level (MNPL = 183,481 animals), and
it is therefore considered within the range of its optimum sustainable
population. The carrying capacity of the population was estimated at
275,298 animals in 2014 (Laake et al. 2018). The total human caused
mortality is less than the PBR of 14,011.
Corrections to the 2016 and 2017 SARs
Subsequent to announcing the availability of the final 2016 (82 FR
29039, June 27, 2017) and 2017 (83 FR 32093, July 11, 2018) SARs, we
were made aware that the SARs contained some technical errors. In the
2016 North Atlantic right whale SAR, the PBR was listed incorrectly as
1. The correct PBR value for 2016 is 0.9. Similarly, in the 2017 North
Atlantic right whale SAR, PBR was listed as 1.4, but the correct value
is 0.9. In addition, the 2017 SAR for the WNA Central Florida Coastal
Stock of common bottlenose dolphins contained a technical error. In the
``Population Size'' section, the name of the stock was incorrectly
listed as the ``Northern'' Florida Coastal Stock instead of the
``Central'' Florida Coastal Stock. We have corrected the errors and
posted revised versions of the 2016 and 2017 North Atlantic right whale
SARs and 2017 WNA Central Florida Coastal Stock common bottlenose
dolphin SAR on the NMFS website (see Addresses). With this Federal
Register notice, we are notifying the public about the revised
versions.
