Atlantic Highly Migratory Species (HMS); Pelagic Longline 
Research

AGENCY: National Marine Fisheries Service (NMFS), National Oceanic and 
Atmospheric Administration (NOAA), Commerce.

ACTION: Notice; request for comments.

-----------------------------------------------------------------------

SUMMARY: NMFS announces the availability of an Environmental Assessment 
(EA) analyzing the impacts of conducting research with pelagic longline 
(PLL) vessels in portions of the East Florida Coast (EFC) and 
Charleston Bump closed areas. Given the nearly rebuilt status of north 
Atlantic swordfish and recent bycatch reduction measures implemented 
throughout the U.S. PLL fishery, NMFS is proposing to collect baseline 
PLL fishery data in the closed areas to evaluate the effectiveness of 
existing bycatch reduction measures. The EA analyzes monthly and annual 
PLL logbook and pelagic observer program (POP) data on catch and 
bycatch rates of all species in the proposed research area from 1995-
2000 to determine potential impacts of the research fishery on target 
and non-target species. NMFS invites comments from interested parties 
on the EA.

DATES: Written comments on the EA must be received by 5 p.m. on 
November 20, 2007.

SUPPLEMENTARY INFORMATION: NMFS proposes to conduct research with a 
limited number of vessels (two are proposed, but backup vessels may be 
used if breakdowns occur) in portions of the EFC and Charleston Bump 
closed areas (Figure 1). The latitude and longitude coordinates of the 
proposed research area are provided in Table 1. In the EFC closed area, 
the proposed research area would be north of Fort Pierce, FL, beginning 
at 28 degrees north latitude and proceeding north, seaward of the axis 
of the Gulf Stream, to the northern boundary of the EFC closed area at 
31 degrees north latitude. In the Charleston Bump, the proposed 
research area would be north of 31 degrees north latitude and following 
the 200 meter isobath ( ~100 fathom contour) to the northern and 
eastern boundaries of the Charleston Bump closed area. The two areas 
are hereafter referred to collectively as the proposed research area. 
NMFS closed the EFC and Charleston Bump closed areas to PLL gear in 
early 2001 to reduce bycatch of juvenile swordfish, billfish, and other 
HMS (65 FR 47214, August 1, 2000). The Charleston Bump closed area is a 
seasonal closure from February through April every year, whereas the 
EFC closed area is closed year-round to PLL gear. Since that time, the 
swordfish stock has been nearly rebuilt (B=0.99BMSY) and new 
bycatch reduction measures have been implemented throughout the PLL 
fishery (e.g., circle hook requirements, bait requirements, bycatch 
release gear, and careful handling and release workshops). No PLL 
fishing has been authorized in the closed areas since 2001, and NMFS 
has not collected information on the effectiveness of current bycatch 
reduction measures in closed areas where bycatch rates may be

[[Page 62442]]

higher than in other areas. NMFS thus proposes to collect information 
under scientifically rigorous protocols to determine the effectiveness 
of bycatch reduction measures in these closed areas. This information 
will assist NMFS in making appropriate management decisions regarding 
the effectiveness of existing closed areas and bycatch reduction 
technologies, as well as any potential modifications to the closed 
areas.
    NMFS proposes to make a total of 289 sets distributed inside and 
outside the proposed research area over a 12 month period beginning in 
late 2007 or early 2008. Each set would consist of 500 18/0 circle 
hooks with an offset not to exceed 10 degrees with whole dead finfish 
bait and/or squid bait. Vessels would be subject to 100 percent 
observer coverage, and observers or research staff would collect data 
that includes, but is not limited to, catch per unit effort (CPUE) for 
target and bycatch species; discard rates; interaction rates with 
protected species; size of target species; hooking location; mortality 
at haul back; bycatch mortality; and if possible, an evaluation of the 
condition of fish at haul back to allow post-release mortality 
estimates.
    All targeted catch (tunas, swordfish, and sharks) that can be 
legally landed could be harvested and sold by the vessel owners. No 
other compensation would be provided to the vessels. All bycatch would 
be released using NMFS-approved dehooking equipment and appropriate 
safe handling and release protocols. Incidental catch of bluefin tuna 
would be landed consistent with existing regulations. Any mortalities 
of Atlantic Tunas Convention Act (ATCA) regulated species (i.e., tunas 
and swordfish) and sharks would be counted against the appropriate 
quotas. Non-target species and protected resources would be tagged and 
released alive, consistent with requirements of the Terms and 
Conditions of the 2004 Biological Opinion issued for the fishery, and 
research objectives.
    The EA analyzed the status quo and two alternatives on different 
proposed research areas within the EFC and Charleston Bump areas. A 
fourth alternative to conduct research throughout the entire EFC and 
Charleston Bump closed areas was considered but not further analyzed. 
Based on analysis in the EA of PLL and POP data from 1995-2000 and 
prior to the closures and circle hook requirements going into effect, a 
limited number of interactions with leatherback sea turtles (four based 
on PLL data and six based on POP data over six years) and loggerhead 
sea turtles (five based on PLL data and 12 based on POP data over six 
years) occurred in the proposed research area. Under a worst case 
scenario using estimates from the POP data, and applying anticipated 
fishing effort in the research fishery to pre-closure J-hook catch 
rates, two leatherback and six loggerhead sea turtle interactions may 
occur as a result of the research fishery. Given the significantly 
lower interaction and mortality rates of Atlantic sea turtles with 
circle hooks, this action is not expected to significantly increase 
fishery interactions with, or mortalities of, sea turtles. The 
predicted interactions would not cause the Incidental Take Statement in 
the 2004 Biological Opinion for the PLL fishery to be exceeded, and 
would not be expected to jeopardize the continued existence of sea 
turtles. Incidental takes of, or interactions with, protected species 
that are listed as threatened or endangered under the Endangered 
Species Act taking place under the research fishery would be counted 
against the authorized incidental take levels specified in the 2004 
Biological Opinion for the PLL fishery.
    The EA includes similar analyses of PLL and POP data from 1995-2000 
on catch rates, live and dead discard rates, and retained numbers of 
swordfish, bluefin, yellowfin, and bigeye tunas, large coastal sharks, 
and pelagic sharks. Based on the worst case scenario from the POP data, 
and applying anticipated fishing effort in the research fishery to pre-
closure J-hook catch rates, an estimated 1,083 swordfish are predicted 
to be retained, 973 discarded alive, and 360 discarded dead; zero (0) 
bluefin tuna are predicted to be caught or discarded; nine white marlin 
are predicted to be discarded alive and 13 dead; 10 blue marlin are 
predicted to be discarded alive and 14 dead; 113 large coastal sharks 
are predicted to be kept; 124 discarded alive, and 50 discarded dead 
(depending upon available quota); and 21 pelagic sharks are predicted 
to be kept, 81 discarded alive, and 11 discarded dead (depending upon 
available quota). Given the known and anticipated mortality reduction 
benefits of circle hooks for Atlantic HMS relative to J-hooks, the 
estimates above are likely over-estimates. As a result, this action is 
not expected to significantly increase the retention or bycatch of HMS.
    All fishing activities would be monitored by Federal fisheries 
observers or trained research staff to provide data on longline gear 
configuration; target and incidental catch; bycatch of billfish, 
juvenile swordfish, and bluefin tuna; and sea turtle interactions. NMFS 
currently collects this information on selected PLL vessels through the 
POP.
    Even though fishing effort will increase in the proposed research 
area, fishing effort across the entire fishery is not anticipated to 
increase because vessels participating in the research fishery would 
have otherwise been fishing commercially for HMS in open areas.
    The regulations that prohibit the proposed activities absent 
issuance of an EFP, include requirements for vessel reporting (50 CFR 
635.4) and fishing in a closed area (50 CFR 635.21(c)(2)). All other 
relevant regulations concerning HMS at 50 CFR Part 635 would apply.
    NMFS is requesting public comment on the EA because the fishing 
activities are proposed to occur in closed areas, specifically the EFC 
and Charleston Bump. If NMFS proceeds with the proposed research as 
described in the EA, then NMFS would issue the necessary exempted 
fishing permits to authorize the research activity.
