Loggerhead Turtles Record a Passing Hurricane

September 1, 2020 — The following was released by NOAA Fisheries:

In early June 2011, NOAA Fisheries researchers and colleagues placed satellite tags on 26 loggerhead sea turtles in the Mid-Atlantic Bight. The tagging was part of ongoing studies of loggerhead movements and behavior. The Mid-Atlantic Bight, off the U.S. East Coast, is the coastal region from Cape Hatteras, North Carolina to southern Massachusetts. A little more than 2 months later, on August 28, Hurricane Irene passed through the area, putting 18 of the tagged turtles in its direct path. The researchers were able to track changes in the turtles’ behavior coinciding with the hurricane, and found that they reacted in various ways.

“Hurricanes are some of the most intense weather events loggerheads in the mid-Atlantic experience, and we thought it was worth investigating how turtles in our dataset may be influenced by these dramatic environmental changes,” said Leah Crowe, a contract field biologist at the NOAA Northeast Fisheries Science Center’s laboratory in Woods Hole, Massachusetts, and lead author of the study published recently in Movement Ecology.  “It was a perfect storm situation in terms of location, timing, and oceanographic conditions. We found that the turtles responded to the changes in their habitat in different ways.”

Satellite tags attached to a turtle’s carapace, or shell, transmitted the turtles’ location and dive behavior. They also  recorded sea-surface temperatures and temperature-depth profiles for approximately 13 months. This enabled the researchers to investigate the movements of 18 juvenile and adult-sized loggerhead turtles and associated oceanographic conditions as the hurricane moved through the region.

Most of the turtles moved northward during the hurricane, aligning themselves with the surface currents — perhaps to conserve energy. Researchers observed longer dive durations after the hurricane for turtles that stayed in their pre-storm foraging areas. Some dives lasted an hour or more, compared with less than 30 minutes for a typical dive before the storm.

The turtles that left their foraging areas after the hurricane passed moved south earlier than would be expected, based on their normal seasonal movements. This change was also more than a month earlier than the typical seasonal cooling in the water column, which is also when the foraging season for loggerhead turtles ends in the Mid-Atlantic Bight.

“Loggerheads experience environmental changes in the entire water column from the surface to the bottom, including during extreme weather events,” said Crowe. “This study was an opportunistic look at turtle behavior during a hurricane. Their behavior makes loggerheads good observers of oceanographic conditions where they forage.”

Hawaiian swordfish catches to recommence after loggerhead-related closure

January 21, 2020 — The US state of Hawaii’s swordfish fishery is expected to land its first catch in nine months this weekend (Jan. 18-19), after closing on Mar. 19, 2019 upon reaching the loggerhead turtle interaction cap.

The fishery produces about 55% of America’s domestic swordfish and supplies 14% of the total US swordfish market.

“Without Hawaii swordfish, US markets will increase their dependence on foreign suppliers,” said Kitty Simonds, executive director of the Western Pacific Regional Fishery Management Council (WPRFMC), which manages the fishery.

“Our pelagic longline fisheries are well managed and rigorously monitored, and regulations are enforced. International fishery management organizations consider them model fisheries and have adopted many of the measures we developed. Our fishery targets the North Pacific stock, which is healthy…and avoids the troubled Eastern Pacific and South Atlantic stocks.”

Hawai’i Shallow-Set Longline Fishery Has No Discernable Impact on Sea Turtle Populations

October 17, 2019 — The following was released by the Western Pacific Regional Fishery Management Council:

Scientists from throughout the Pacific meeting this week in Honolulu found that mortality by the Hawai’i shallow-set longline fishery on loggerheads and leatherbacks are “trivial” and have no impact on their population levels. The fishery, which produces 55 percent of the domestic US catch of swordfish, was shut down on March 19, 2019, after it reached the annual limit of 17 physical interactions with North Pacific loggerhead sea turtles. All 17 were released alive. Since 2004, more than 99 percent of the turtles with which the fishery have interacted were released alive.

The Scientific and Statistical Committee (SSC) of the Western Pacific Regional Fishery Management Council made its conclusion after reviewing the assessment of population level impacts of loggerhead and leatherback turtle interactions in the Hawai’i shallow-set longline fishery presented by T. Todd Jones and Summer Martin of the NOAA Fisheries Pacific Islands Fisheries Science Center (PIFSC) and Zachary Siders of the University of Florida. The assessment is a post-interaction mortality model for the shallow-set longline fishery that evaluates the fishery’s impact on the population trend. The model was developed by PIFSC and based on a population vulnerability assessment for the species conducted in 2018.

The model predicted that the anticipated annual take by the Hawaii shallow-set fishery would have no significant impact on the long-term abundance of these two marine turtle species over the next 100 years. The model also indicated that the past take made no discernable difference on the historical population trend. The model is considered to be conservative because the take is only applied to index beaches, which accounts for about 52 percent of the loggerhead population and about 75 percent of the leatherback population.

The SSC endorsed the take model developed for the shallow-set longline fishery as the best scientific information available for evaluating the impacts of the fishery on loggerhead and leatherback turtle populations. It recommended that PIFSC apply the model to the take data for the Hawai’i deep-set longline fishery (which targets bigeye tuna) and the American Samoa longline fishery (which targets albacore tuna) to provide a robust scientific assessment to be considered in ongoing Endangered Species Act (ESA) consultations. The SSC further encouraged consideration of transferred effect of the US longline fishery closure on target species as well as protected species. [Note: Markets seek foreign imports, which have less stringent regulations and monitoring, when domestically caught fish is unavailable.] The SSC reiterated that the 25 percent reduction goal in the shallow-set longline fishery biological opinion (BiOp) completed by the National Marine Fisheries Service (NMFS) in June 2019 as “aspirational, overly conservative and not supported by the scientific information presented in the final BiOp, especially in light of the results of the new take model.” The BiOp would allow the fishery up to 16 leatherback sea turtle interactions annually. The SSC recommended that the Council reevaluate its position on the reasonable and prudent measures in the BiOp in light of the model results.

The Council will consider these and other recommendations by the SSC and its other advisory bodies when it meets Oct. 22 to 24, 2019, at the Tauese P. F. Sunia Ocean Center in Utulei, American Samoa.

Climate Change Will First Benefit, Then Hurt Loggerhead Sea Turtles

September 9, 2019 — For some animals, climate change is expected to become a major threat to their survival. For others, a warmer world may actually be beneficial. For the loggerhead sea turtle, it’s a little bit of both.

The loggerhead sea turtle’s vast range stretches across the globe and is composed of nine ‘distinct population segments’ according to the National Oceanographic and Atmospheric Administration (NOAA). Despite the loggerhead’s expansive range, five of the population segments are considered endangered, while the remaining four are considered threatened.

Given the poor state of loggerhead sea turtle populations worldwide, researchers want to understand how predicted changes in climate will further harm, or benefit, the species.

Federal Managers Finalize Turtle Interaction Measures with Hawai’i Swordfish Fishery

August 13, 2019 — SEAFOOD NEWS — Hawai’i swordfish fishermen finally have a plan for loggerhead and leatherback sea turtle bycatch. The Western Pacific Regional Fishery Management Council finalized new mitigation measures last week for the shallow-set longline fishery, after waiting for the completion of a new biological opinion for more than a year.

Hawai’i-based longliners provide nearly half of the domestic swordfish to the U.S. market.

The amendment to the Pelagic Fishery Ecosystem Plan sets an annual fleet-wide hard cap limit on the number of leatherback turtle interactions (hooked or entangled) at 16. The Council did not recommend setting an annual fleet-wide hard cap for loggerheads in light of that species’ improving population trends and other mitigation measures, but the Council retains the authority to set a hard cap limit in the future if necessary. The Council noted that few interactions lead to serious injury or mortality of the animal, which is normally released unharmed.

To limit the impact of interactions on sea turtles and to promote year-round fishing opportunities, the Council further recommended the establishment of individual trip interaction limits of five loggerheads and two leatherback turtles. Once a vessel reaches either of these trip limits, the vessel is required to return to port and will be prohibited from engaging in shallow-set longline fishing for five days after returning. This action is expected to allow sea turtle “hot spots” to disperse, while encouraging fishermen to take action to avoid sea turtle interactions before the trip limits are reached, the Council said in a press release.

Additional restrictions set trip limits on each vessel. Any vessel that reaches the trip limit twice for either leatherback or loggerhead sea turtles in a calendar year will be prohibited from shallow-set longline fishing for the remainder of that year. The following calendar year, these vessels will have an annual vessel limit equivalent to a single trip limit – either five loggerheads or two leatherbacks. These additional vessel restrictions are measures required under the new BiOp prepared by NMFS.

The Council’s Scientific and Statistical Committee noted in its report that in light of the BiOp finding that the fishery does not jeopardize the continued existence of these sea turtles, the additional restrictions are punitive. Furthermore, they are not supported by the scientific information that show the fishery has no adverse impacts to the overall loggerhead and leatherback populations.

NMFS Pacific Islands Regional Office Regional Administrator Michael Tosatto reminded the Council that it is the Council’s “mandate to minimize interactions with protected species … minimize means approach zero,” according to the press release.

“You’ve heard the expression barking up the wrong tree – we’re swimming in the wrong ocean,” Council member Ed Watamura, said in the statement. He noted the disproportionate impact the Hawai’i fleet experiences due to the U.S. government’s strict regulations, while foreign fleets have much more impacts to sea turtles. With almost 100 percent of the incidentally hooked turtles returning to the ocean alive, the Hawai’i swordfish fishery has had negligible impact on the leatherback and loggerhead turtle populations in the Pacific Ocean.

Furthermore, threats to loggerhead and leatherback turtles in other parts of the populations’ range include bycatch in artisanal and coastal fisheries in the Western Pacific, direct harvesting of eggs and adult turtles, nest predation by feral animals, beach nesting habitat alteration, and climate change.

The Council did not recommend setting a fleet-wide interaction limit for loggerhead turtles, recognizing that the status of the population has improved since the Council first recommended implementing hard caps for the shallow-set longline fishery in 2004, according to the press release. A recent population assessment of the North Pacific loggerhead turtles showed the population is growing at an annual rate of 2.4 percent, and the total is estimated at 340,000 individuals. Considering this population growth and the additional restrictions on trip limits, the Council found the fleet-wide hard cap limit for loggerhead turtles is no longer necessary or appropriate to conserve the species.

Final action taken yesterday by the Council was a culmination of a nearly two-year process to improve measures for managing loggerhead and leatherback turtle interactions in the shallow-set longline fishery. The process was stalled for nearly a year due to NMFS’ delay in completing the new BiOp, which was originally scheduled to be completed in October 2018. The Council’s final recommendation will be forwarded to the Secretary of Commerce, followed by a rule making process including a public comment period.

Federal Managers Finalize Turtle Interaction Measures with Hawai’i Swordfish Fishery

August 12, 2019 — The following was released by the Western Pacific Regional Fishery Management Council:

The Western Pacific Regional Fishery Management Council met on Thursday, August 8 to amend the Pelagic Fishery Ecosystem Plan with revisions to the loggerhead and leatherback turtle mitigation measures for the Hawai‘i shallow-set longline fishery. The amendment sets an annual fleet-wide hard cap limit on the number of leatherback turtle interactions at 16. An interaction occurs whenever a sea turtle becomes hooked or entangled in longline gear.  Few interactions lead to serious injury or mortality of the animal, which is normally released unharmed.  The Council did not recommend setting an annual fleet-wide hard-cap for loggerheads in light of that species’ improving population trends and other mitigation measures, but the Council retains the authority to set a hard cap limit in the future if necessary.

To limit the impact of interactions on sea turtles and to promote year-round fishing opportunities, the Council further recommended the establishment of individual trip interaction limits of five loggerheads and two leatherback turtles. Once a vessel reaches either of these trip limits, the vessel is required to return to port, and will be prohibited from engaging in shallow-set longline fishing for five days after returning.  This action is expected to allow sea turtle “hot spots” to disperse, while encouraging fishermen to take action to avoid sea turtle interactions before the trip limits are reached.

Additional restrictions set trip limits on each vessel – any vessel that reaches the trip limit twice for either leatherback or loggerhead sea turtles in a calendar year will be prohibited from shallow-set longline fishing for the remainder of that year. The following calendar year, these vessels will have an annual vessel limit equivalent to a single trip limit – either 5 loggerheads or 2 leatherbacks. These additional vessel restrictions are measures required under a new biological opinion (BiOp) prepared by the National Marine Fisheries Service (NMFS).

Federal Managers to Make Final Recommendations on Leatherback and Loggerhead Sea Turtle Interactions with Hawai’i Swordfish Fishery (6 August 2019)

August 7, 2019 — The following was released by the Western Pacific Regional Fishery Management Council:

The Western Pacific Regional Fishery Management Council will meet on Aug. 8, 2019, to consider final recommendations on the management of the Hawai’i swordfish fishery’s interactions with leatherback and loggerhead sea turtles. The National Marine Fisheries Service (NMFS) provided a final biological opinion (BiOp) during the 178th Council meeting in June 2019 (originally due October 2018), but the Council deferred action at the time to allow adequate time to review the final BiOp.

The final BiOp determined that the swordfish fishery is not jeopardizing the continued existence of these sea turtles and authorizes the accidental hooking and subsequent release of 21 leatherbacks and 36 loggerheads. Based on observer data since 1994, 100 percent of leatherback turtles and over 99 percent of loggerhead turtles observed in this fishery have been released alive with a high chance of survival. Despite finding that the impacts of the fishery are not expected to appreciably reduce these two populations’ likelihood of surviving and recovering in the wild, the final BiOp requires additional measures to further reduce incidental captures and mortalities. Specifically, if the fleetwide leatherback interaction reaches the “hard cap” of 16, the BiOp requires that the fishery be closed for the remainder of the calendar year.

The final BiOp also requires implementing individual trip limits of two leatherback or five loggerhead interactions per vessel per trip. However, once a vessel reaches a trip limit twice in a year, it will be prohibited from shallow-set fishing for the remainder of the year, and the vessel will be subject to an annual vessel limit of 2 leatherbacks or 5 loggerheads for the following year. There is no hard cap required in the new BiOp for loggerhead turtles, which has a stable and increasing population.

Over the last five years in the North Pacific Ocean, approximately 99 million hooks were deployed overall in shallow-set longline fisheries annually (reported by the Western and Central Pacific Fisheries Commission). Of those, on average 1.2 million hooks (about 1 percent) are deployed annually by the Hawai’i-based shallow-set longline fishery.

“We know what the US shallow-set longline fishing impacts are on loggerheads and leatherbacks in the Pacific due to our 100 percent observer coverage,” remarked Council Chairman Archie Soliai. “When other countries are struggling to meet the internationally-required 5 percent observer coverage, how much confidence do we have about the loggerhead and leatherback impacts for the remaining 98 million hooks set?”

The Council’s recommendation from its 177th meeting in April 2019 was to manage the fishery under annual fleetwide hard cap limits of 16 leatherbacks and 36 loggerheads. The Council initially put the hard caps in place in 2004 as a backup measure when new bait and gear changes were implemented, which, along with other measures, reduced interactions by about 90 percent. The Council also recommended individual trip interaction limits of two leatherbacks and five loggerheads. Once either limit is reached, the vessel would be required to immediately return to port, after which they may resume shallow-set fishing. The original Council recommendations were much simpler and did not include additional vessel restrictions.

The Council will take all information into account, including the measures required under the final BiOp, when it considers final action this week.

The Council’s Hawai‘i Archipelago Fishery Ecosystem Plan Advisory Panel (AP) and Scientific and Statistical Committee (SSC) will meet on Aug. 7, 2019, in advance of the Council meeting to discuss recommendations to the Council for the final action on managing loggerhead and leatherback sea turtle interactions in the Hawai’i-based shallow-set longline fishery.

The AP, SSC and Council meetings can be attended remotely by web conference at: https://wprfmc.webex.com/join/info.wpcouncilnoaa.gov. The Council office will also serve as a meeting host site: 1164 Bishop Street, Suite 1400, Honolulu, Hawai’i.

Summary of Action Items for the 179th Meeting of the WPRFMC

July 24, 2019 — The following was released by the Western Pacific Regional Fishery Management Council:

The 179th meeting of the Western Pacific Regional Fishery Management Council will convene on August 8, 2019 via web conference. The Council will consider and may take action on the issue summarized below, including any public comments on it. Written public comments should be received by the Council’s executive director by 5 p.m. (Hawai ‘i Standard Time), August 5, 2019 by postal mail, fax or email as indicated below. Opportunities to present oral public comment will be provided during the 179th Council meeting.

Summary of Action Item

1. Managing Loggerhead and Leatherback Sea Turtle Interactions in the Hawai’i-Based Shallow-Set Longline Fishery   

The Hawai‘i shallow-set longline fishery, managed under the Western Pacific Regional Fishery Management Council’s Pelagic Fishery Ecosystem Plan (FEP), reduced loggerhead and leatherback turtle interactions by approximately 90 percent through the implementation of new technologies (large circle hooks and mackerel-type bait). Regulatory Amendment 3 to the Pelagic Fishery Management Plan (FMP) that established the requirements for these gear measures also established annual interaction limits for loggerhead and leatherback turtles (“hard caps”), which, if reached, would trigger the closure of the fishery for the remainder of the calendar year. The existing annual fleet-wide hard caps, first implemented in 2004, prevent loggerhead and leatherback takes above the specified limit, but do not provide early response to higher interaction rates that may indicate a potential for higher impacts to sea turtle populations or a fishery closure early in the calendar year. Effective management of loggerhead and leatherback turtle interactions in the Hawai‘i shallow-set longline fishery should consider responsive measures that can help ensure year-round operations while addressing the needs for protected species conservation. At its 172nd meeting in March 2018 and 173rd meeting in June 2018, the Council considered a range of management measures to address this need.

WPRFMC: BiOp Shows Hawai’i Longline Swordfish Fishery Poses No Jeopardy to Sea Turtles

July 2, 2019 — SEAFOOD NEWS — The National Marine Fisheries Service issued a biological opinion last week that shows the Hawai’i shallow-set longline fishery does not jeopardize loggerhead or leatherback sea turtles, according to the Western Pacific Regional Fishery Management Council.

The Council deferred making final recommendations on the management of loggerhead and leatherback sea turtle interactions in the fishery three times since October 2018 as it awaited the final document. It again deferred action as the 500-page document was provided to Council members only 30 minutes before it took up the issue on its agenda during last week’s meeting.

Council Member Michael Goto noted the gravity of the BiOp. The fishery, which accounts for half of the U.S. swordfish production, is currently closed due to a settlement made in the 9th Circuit Court, which found inconsistencies in the previous 2012 BiOp. Goto argued against making “a snap decision on a process that took almost a year to complete,” he stated in a press release. ” … In my opinion, the review can’t be done within the course of day.”

To ensure Council members have time to read the 500-page document, the Council will take up final action during a special meeting to be held by teleconference in late July or early August. In advance of this meeting, the Council will convene its Scientific and Statistical Committee and the Hawai’i Advisory Panel to review and make recommendations for Council consideration.

The Council’s initial recommendation was to manage the fishery under annual fleet-wide limits of 16 leatherbacks and 36 loggerheads. It also recommended trip limits of two leatherback and five loggerheads per vessel. Once either limit is reached, the vessel would be required to immediately return to port after which they may resume shallow-set fishing. The fishery has 100 percent observer coverage to monitor every turtle interaction encountered by a shallow-set vessel.

The final BiOp authorizes the accidental hooking and subsequent release of 21 leatherbacks and 36 loggerheads. However, if the fleetwide leatherback interaction reaches 16, the BiOp requires the fishery be closed for the remainder of the calendar year, according to the WPRFMC statement. The final BiOp also includes the Council’s recommended trip limit of two leatherbacks or five loggerheads per vessel per trip. However, once a vessel reaches this trip limit twice in a year it can no longer shallow-set fish for the remainder of the year.

Furthermore, the following year that vessel would be allowed to reach the trip limit only once before it is prohibited from shallow-setting for the remainder of the year. There is no hard cap required in the new BiOp for loggerhead turtles, which has a stable and increasing population.

During public comments on this item, Hawaii Longline Association Executive Director Eric Kingma said that, since 2004, the fishery has been operating under the most restrictive regime possible for the fishery, including hard caps for sea turtle interactions, 100 percent observer coverage, gear and bait requirements, release and handling requirements, set limits and set certificates. Those measures reduced the fishery’s interactions with sea turtle by more than 90 percent and are now the standards internationally for shallow-set fisheries for swordfish

“This fishery is not jeopardizing the continued existence of these sea turtle populations, or any other ESA-listed population,” Kingma said in the press release. He described the measures as “overly punitive” and “not consistent with the impact. … [We] have a highly regulated fishery, one of the most regulated fisheries in the world, the most highly monitored regime, 100 percent observer coverage. You can’t get any more certain than that. … And we know the impact. The impact on these species is non-jeopardy.”

Kingma said HLA supports the trip limits but not the hard caps because they are “a blunt measure that is not the appropriate match to the impact.” Furthermore, HLA supported the Council deferring because “no one should be put in that position where they have to make a decision upon receiving a 500-page document,” Kingma said in the release.

In related matters, the Council also requested NMFS complete the Endangered Species Act Section 7 consultations for the Hawai’i deep-set and American Samoa longline fisheries by Sept. 1, and for the U.S. tropical purse-seine fishery by Oct. 1. The Council further requested that NMFS provide the Council with any draft Reasonable and Prudent Measures or Reasonable and Prudent Alternatives prior to the release of the entire draft BiOp, as well as the full draft BiOp.

Scallop Research Set-Aside Program Supports 13 Projects for 2019-2020; Resource Surveys Once Again Top the List

May 8, 2019 — The following was published by the New England Fishery Management Council:

The Atlantic Sea Scallop Research Set-Aside (RSA) Program will support 13 projects during the 2019-2020 award cycle that address resource surveys, dredge efficiency, bycatch reduction, fishery impacts on loggerhead turtles, potential offshore wind development impacts on larval and juvenile scallop transport, and more. The projects focus on scallop research priorities identified by the New England Fishery Management Council, which ranked resource surveys as the highest priority.

The awards were announced today by the NOAA Fisheries Northeast Fisheries Science Center. Collectively, these awards are expected to generate more than $14 million. This includes an estimated $2.8 million to fund the research and $11.4 million to compensate industry partners who harvest set-aside quota. No federal money is involved, making this a true industry-funded program.

• The New England Council approved research priorities in June 2018 for the 2019-2020 RSA projects.
• The Council will develop a new list of priorities at its June 2019 meeting for 2020-2021 projects.

The Council established the Scallop RSA Program to address research questions that support the management of the scallop resource. Each year during the specification-setting process, the Council “sets aside” 1.25 million pounds of scallops to carry out RSA projects. The work is conducted collaboratively between fishermen and scientists. Research results directly contribute to stock assessments and help the Council better manage the fishery overall.

While the Council sets the annual research priorities, NOAA Fisheries manages the RSA competition and administers the program.
