NOAA: Team to Focus on Right Whale Survival This Week

April 22, 2019 — The following was published by NOAA Fisheries:

On April 23, a group of approximately 60 fishermen, scientists, conservationists, and state and federal officials will come together to discuss ways to further reduce serious injury and mortality of endangered North Atlantic right whales caused by trap/pot fishing gear. The group will meet in Providence, Rhode Island for four days. At the end of the meeting, they hope to agree on a suite of measures that will reduce right whale serious injuries and deaths in fishing gear in U.S. waters from Maine to Florida to less than one whale per year, the level prescribed by the Marine Mammal Protection Act.

“Tackling entanglements is critical to the recovery of the North Atlantic right whale population, and we can’t do it without the assistance and cooperation of those who know best how the fishing industry interacts with large whales,” says Mike Pentony, regional administrator for NOAA Fisheries Greater Atlantic Region. “The continued participation and dedication of our industry, science, NGO, and agency partners is absolutely necessary to future success.”

About Right Whales

These whales, which got their name from being the “right” whales to hunt because they floated when they were killed, have never recovered to pre-whaling numbers. Due in part to conservation measures put in place to protect these whales from incidental entanglements in fishing gear and vessel strikes, we saw steady population growth from about 270 right whales in 1990 to about 480 in 2010. But in 2010, another downward trajectory began. This downward trend, exacerbated by an unprecedented 17 mortalities (particularly in the Gulf of St. Lawrence snow crab fishery) in 2017, brought a new urgency to modify the existing Atlantic Large Whale Take Reduction Plan.

That Plan, developed by the team of stakeholders meeting next week, identifies a number of conservation measures from area closures to gear modifications that U.S. fixed gear fishermen have already implemented. Despite these efforts, today the population is estimated to be fewer than 411 whales. Only twelve births have been observed in the three calving seasons since the winter of 2016/2017, less than one third the previous average annual birth rate for right whales. This accelerates the trend that began around 2010, with deaths outpacing births in this population.

Take Reduction Planning

The Marine Mammal Protection Act requires that if serious injuries and mortalities to a population of marine mammals due to U.S. commercial fisheries is above a level that the stock can sustain, NOAA Fisheries convene Take Reduction Team to develop consensus recommendations on how to reduce this threat.

The immediate goal of a Take Reduction Team is to develop a to reduce incidental mortality and serious injury to a level, known as the “potential biological removal” level, that allows the stock to stabilize or grow, rather than decline. Although it’s been in existence since 1997, the Atlantic Large Whale Take Reduction Plan has not been able to consistently reduce serious injuries and mortalities to below the potential biological removal level.

Cost of Entanglement

Entanglements are currently the leading cause of known right whale mortality. More than 80 percent of right whales carry scars that indicate that they have been entangled in fishing lines, and nearly 60 percent of those are entangled more than once. Not all entanglements drown whales.  Some prevent a whale from feeding, increase the energy a whale needs to swim and feed and cause pain and stress to the animal, which weakens it. Biologists believe that the additional stress of entanglement is one of the reasons that females are calving less often; females used to have calves every 3-5 years, and now are having calves every 6-10 years.

In recent years, most documented fishing gear entanglements of large whales (like right and humpback whales) that result in serious injury and mortality come from trap/pot gear. The traps lie on the ocean floor and are connected to buoys at the surface by long vertical buoy lines.

Many whales that are entangled are discovered after the event, with no gear attached. In some instances, gear is retrieved, analyzed, and stored for future analysis; much of this retrieved rope is consistent with buoy lines. That said, 71 percent of all recovered/observed gear (2009-2018) from right whales cannot be matched to a specific fishery or site.

Strategies for Reducing Risk

In Providence next week, the Team will be developing and discussing potential measures to modify the Take Reduction Plan, including updates to the current gear marking strategy, seasonal area closures, and reducing the risk of vertical lines through the use of weak rope. Many of these measures were proposed by Team members during an October 2018 meeting to discuss possible options to discuss at the April 2019 meeting. In advance of this meeting, the team particularly requested two things: 1. Clarification of a target percent reduction in serious injury and mortality, and 2. An ability to evaluate and compare different risk reduction elements from Team proposals.

A Target Reduction Level

Based on the 2016 population estimate, the Northeast Fisheries Science Center’s North Atlantic right whale stock assessment establishes a potential biological removal level of 0.9 whales per year — i.e. slightly less than one whale suffering human-caused mortality or serious injury from any source in a given year.

Currently, NOAA Fisheries estimates that U.S. fisheries are responsible for 2.5 to 2.6 observed serious injuries and mortalities each year. Scientists estimate that we only observe 60 percent of the serious injuries and mortalities, which would bring the U.S. total to about 4.3. To get to 0.9 will require a reduction of 60-80 percent of serious injuries and mortalities.

A Risk Analysis Decision Tool

Determining how to judge the expected conservation value of any particular measure is a complicated task. To create a model to assess risk reduction, the model needs to first identify the current risk landscape, overlaying information on the density of trap/pot vertical lines, the distribution of whales, and the relative risk of the gear configuration associated with the lines (strengths/diameters of lines, lengths of trawls). Working collaboratively, the model combines Industrial Economics Inc.’s improved trap/pot vertical line model and the Duke Marine Spatial Ecology Lab’s marine mammal density model, as well as risk assessment weights provided by Take Reduction Team members, Agency large whale scientists and managers, and permitted whale disentanglers. With these data sets, scientists at NOAA’s Northeast Fisheries Science Center developed a risk assessment tool that will be used at next week’s meeting.  This tool represents a substantial leap forward and provides the Team with the best available information to determine risk and support their deliberations.

Next Steps

After this meeting, we will use recommendations from the Team to begin rulemaking in May. At various points during rulemaking there will be a continued opportunity for public comment.

“I’m confident we have the right people around the table to tackle this problem,” says Mike Asaro, Acting Protected Resources Assistant Regional Administrator. “This is a complex issue but with the cooperation and active engagement from the people who know this issue best, I have hope that following the meeting, we will have a solid set of conservation measures to proceed to rulemaking that will allow the fishing industry and whales to coexist and thrive.”

Canadian-U.S. Lobstermen’s Town Meeting: U.S. and Canadian lobstermen have a whale of a problem

April 17, 2019 — Department of Marine Resources Commissioner Patrick Keliher sure knows how to quiet a room.

On April 5, about 100 members of the U.S. and Maine lobster industry — fishermen, dealers, scientists, and regulators — gathered for the 15th Canadian-U.S. Lobstermen’s Town Meeting at the Westin Portland Harborview Hotel in Portland. There they heard Keliher announce that he’d just received an email from NOAA Fisheries announcing that, in order to protect endangered right whales, “the U.S. fishery will likely have to be reduced 60 to 80 percent.”

It’s a testament to the cardiac health of Maine and Canadian lobstermen that the statement didn’t produce a mass heart attack, especially since it came during a discussion of what fishing restrictions might be imposed by NOAA Fisheries this spring to meet the demands of the federal Endangered Species and Marine Mammal Protection acts.

What almost everyone in the room heard, though, wasn’t all that Keliher said. Thanks to a snafu with the microphone, the audience missed the beginning of the NOAA statement that said “whale mortalities” from U.S. fisheries would have to be reduced by “60 to 80 percent,” not the fisheries themselves.

Right Whales Are Migrating

North Atlantic right whales are on the move along the Atlantic coast of the U.S. With an unprecedented 20 right whale deaths documented in 2017 and 2018, NOAA is cautioning boaters to give these endangered whales plenty of room. We are also asking commercial fishermen to be vigilant when maneuvering to avoid accidental collisions with whales, remove unused gear from the ocean to help avoid entanglements, and use vertical lines with required markings, weak links, and breaking strengths.

Right Whales in Trouble

North Atlantic right whales are protected under the U.S. Endangered Species Act and the Marine Mammal Protection Act. Scientists estimate there are slightly more than 400 remaining, making them one of the rarest marine mammals in the world.

In August 2017, NOAA Fisheries declared the increase in right whale mortalities an “Unusual Mortality Event,” which helps the agency direct additional scientific and financial resources to investigating, understanding, and reducing the mortalities in partnership with the Marine Mammal Stranding Network, Canada’s Department of Fisheries and Oceans, and outside experts from the scientific research community.

Change Is in the Air: Western Pacific SSC Suggests New Approaches for Suite of Issues

March 19, 2019 — SEAFOOD NEWS — The Scientific and Statistical Committee of the Western Pacific Regional Fishery Management Council concluded a three-day meeting last week in Honolulu with a suite of recommendations to more effectively address issues facing fisheries in the U.S. Pacific Islands. The Council will consider those recommendations this week.

Regarding false killer whales, the SSC recommended inclusion of a population variability analysis to supplement the use of and reduce the variability of potential biological removal estimates.

The Southern Exclusion Zone (SEZ), a 132,000 square mile area in the offshore waters around the main Hawaiian Islands, was closed to the Hawai’i longline fishery on Feb. 22, 2019, after its interactions resulted in a mortality and serious injury determination for two false killer whales. With the SEZ closed, less than 18 percent of US exclusive economic zone around Hawai’i remains open to the fishery.

The SEZ may reopen in 2020 if the average estimated false killer whale M&SI in the deep-set longline fishery within the remaining open areas of the EEZ around Hawai’i for up to the five most recent years is below the potential biological removal for the species, the WPRFMC said in a press release.

The Honolulu-based longliners land about $100 million of sashimi-quality tuna, which stays principally in the state.

The PBR is defined by the Marine Mammal Protection Act as the maximum number of animals that can be removed, not including natural mortalities, from a marine mammal stock while allowing that stock to reach and maintain its optimum sustainable population, i.e., its maximum productivity keeping in mind the carrying capacity of the habitat and health of the ecosystem. The SSC recommended the Council request NMFS develop approaches to incorporate population viability analysis to supplement the use of PBR and to reduce uncertainty in PBR estimates. PVA is a species-specific risk assessment method frequently used in conservation biology.

The SSC also requested the Council ask NMFS to provide the data needed for the SSC to develop the PVA in parallel to the NMFS process. Furthermore, it also asked that NMFS develop serious-injury determination criteria for false killer whales that are probability-based. Currently, NMFS considers the impact of a false killer whale determined to be seriously injured to be equivalent to the impact of a dead false killer whale, even though animals determined to be seriously injured are released alive.

Spatial Management: A subgroup of the SSC worked to define benefits and limitations to spatial management actions relative to regional fishery issues and management objectives. The working group explored time-area closures; adaptive/real-time closures and restrictions; permanent no-take closures; and alternative non-spatial management actions, such as gear restrictions.

Members also discussed objectives of management actions, such as increasing targeted bigeye and albacore tuna abundance and reducing Hawai’i longline interactions with sea turtles and false killer whales. The group also identified criteria for evaluating the effectiveness of spatially managed areas. The SSC reviewed the outcomes of the working group and recommended that effective spatial management should have the following:

  • Objectives and performance metrics explicitly specified prior to developing a spatial management area in order to evaluate the effectiveness of the spatial management. The performance metrics should concurrently address conservation, economic and social objectives;
  • Regular monitoring of the performance of the spatial management area; and
  • Planned and tenable compliance monitoring and enforcement. The SSC said permanent closed areas are likely less effective than modifying fishing gear or methods to minimize protected species bycatch. It recommended regulations that would allow industry to find voluntary means to reduce bycatch and have input in the development of mitigation measures.

Hawai’i Kona Crab: The SSC evaluated the benchmark assessment of the Hawai’i Kona crab fishery and determined it is the best scientific information available for status determination and setting harvest limits.

The scientists said the assessment possibly accounted for a limited portion of the stock due to the small geographic extent of the commercial fishery relative to the larger distribution of the stock in Hawai’i as well as a lack of information on noncommercial fishing activities.

It suggested that female crabs discards be recorded on fishermen trip reports and that a stock assessment model be used that can account for sex-specific dynamics, since State of Hawai’i management measures allow the take of males but requires females to be discarded. The SSC recommended that the sex ratio of Kona crab at Penguin Bank be studied to evaluate the potential effects on the stock from the sex-selective fishery and reiterated its strong recommendation that extension of the closed season, changes in mesh size, retention of females and other alternative management options be evaluated to stimulate fishermen participation in this healthy fishery. Fishery participation had declined significantly after the non-retention of female Kona crabs went into effect.

U.S. Territory Longline Bigeye Tuna Quota: Regarding the federal quotas of longline-caught bigeye tuna for the U.S. Pacific Territories that participate in the Western and Central Pacific Fisheries Commission, the SSC noted that the projected impacts of allowing each U.S. Territory to transfer 1,000 or up to 2,000 metric tons of their 2,000 mt quotas to permitted U.S. longline fishing vessels would not lead to bigeye overfishing and are consistent with the Commission’s management objectives.

MAINE: Whale rule changes coming on two tracks

January 9, 2019 — Maine lobstermen and their representatives, along with state fisheries regulators, continue in the trenches of debates about how much the Maine lobster fishery is implicated in the decline of the North Atlantic right whale.

Ongoing efforts to protect the whales from entanglement with fishing gear may result in two different new sets of regulations, Sarah Cotnoir, resource coordinator for the Maine Department of Marine Resources, and Patrice McCarron, executive director of the Maine Lobstermen’s Association, told the Zone B Council last week.

The two sets of regulations come from parallel processes under two federal laws, the Marine Mammal Protection Act (MMPA) and the Endangered Species Act (ESA).

Lethal force approved for sea lion at Willamette Falls

November 16, 2018 — The Oregon Department of Fish and Wildlife’s plan to remove problem California sea lions from the Willamette River Falls using lethal force has been approved by the National Marine Fisheries Service.

The sea lions are protected by the Marine Mammal Protection act, but the federal agency approved the plan because the pinnipeds have put runs of salmon and steelhead in the river in jeopardy of extinction.

ODFW filed the application because analyses showed that high levels of predation by sea lions (25 percent of the steelhead run in 2017) meant there was an almost 90 percent probability that one of the upper Willamette steelhead runs could go extinct.
