National Report on Large Whale Entanglements Confirmed in the United States in 2018

June 11, 2020 — The following was released by NOAA Fisheries:

NOAA Fisheries has released a National Report on Large Whale Entanglements Confirmed in the United States in 2018. Many large whale populations are increasing in the United States, but entanglements in fishing gear or marine debris are a growing threat to the continued welfare and recovery of these species. Severe entanglements can kill or seriously injure large whales. Entanglements involving threatened or endangered species can have significant negative impacts to the population as a whole.

NOAA Fisheries coordinates the Marine Mammal Health and Stranding Response Program, which includes partners in the Large Whale Entanglement Response Network. They help us track and document as many of these incidents as possible. Entanglements represent a serious human-caused threat to large whales at the individual and population levels. Scientists and managers analyze entanglement data to determine:

Rates and severity of entanglements
Type of gear or debris causing the entanglement
Injuries and impact to the animal

Managers use that information to evaluate existing conservation measures and implement new ones as warranted to reduce the threat of entanglements in the future.

There were 105 confirmed entanglement cases nationally in 2018. This was above the 11-year average (70.8 + 21.8) and more than 25 percent higher than the number of cases in 2017. Some of the entanglements involved North Atlantic right whales on the East Coast, which could impede recovery of that critically endangered species. The National Large Whale Entanglement Response Network responded to 37 of 92 cases involving entangled live whales and successfully removed entangling gear from 16 whales. This increased their chances of survival as well as collected important documentation.

New rules for California Dungeness crab fleet seek fewer whale entanglements

May 18, 2020 — The California Department of Fish and Wildlife on Friday unveiled a batch of complex new rules designed to reduce the risk to endangered whales and sea turtles of becoming entangled in commercial Dungeness crab fishing gear.

The draft regulations are set to be finalized before the next commercial season starts in November after a period of public review.

They expand on a framework established under a legal settlement reached last year that allows for the state’s $60-million-a-year crab fishery to be delayed or closed when surveys and other observations suggest a high risk of concentrated fishing gear and marine life overlapping in the same place. The new rules are meant to allow more nuanced risk assessment and precise management actions rather than the closure of large swaths of ocean, as seen in recent seasons.

Among the provisions are options to restrict fishing in certain depths, require crabbers to set only a share of the traps for which they’re permitted or limit intervention to any of six newly established geographic zones, rather than the larger Northern and Central California management districts that currently exist.

In another significant ruling for right whales, a federal judge rules that Massachusetts is violating the Endangered Species Act

May 4, 2020 — In another shot across the bow of the lobster industry, a federal judge ruled Thursday that state regulators have violated the Endangered Species Act by licensing lobstermen to use fishing gear that entangles North Atlantic right whales.

The ruling requires Massachusetts officials to obtain a permit from the National Marine Fisheries Service to license vertical buoy lines, the ropes that connect lobster traps on the seafloor to buoys at the surface.

Those lines are vital to the fishery but have been the leading cause of death of right whales over the past decade, accounting for more than half of all known causes. In the past three years, 30 right whales have died, reducing their population to around 400.

In her ruling, Judge Indira Talwani of the US District Court in Boston said the continued use of buoy lines was likely to cause further harm to right whales, which scientists say could become functionally extinct within the next 20 years.

ISSF Awards Grand Prize in Seafood Sustainability Contest

March 10, 2020 — The following was released by the International Seafood Sustainability Foundation:

Doctoral student Melissa Cronin of the University of California, Santa Cruz, is the Grand Prize winner in ISSF’s International Seafood Sustainability Foundation (ISSF) Seafood Sustainability Contest. She receives a $45,000 prize from ISSF for her contest entry, “Incentivizing Collaborative Release to Reduce Elasmobranch Bycatch Mortality,” which proposes handling-and-release methods that purse-seine vessel skippers and crew can use to reduce the mortality of manta rays and devil rays incidentally caught during tuna fishing.

Her winning proposal calls for cooperative workshops with purse-seine skippers and observers, offering financial rewards for the design, testing, and onboard implementation of feasible, scalable techniques for safely removing rays from vessel decks.

It also includes training observers in tagging rays to track their post-release survival. Rays, in addition to sharks, are the species groups most vulnerable in the purse-seine fishery. In the Indian Ocean, for example, rays comprise the majority of bycatch in tuna fishers’ free-school sets: bycatch overall on such sets represents 0.9% of the total catch, and 34% of that is rays.

Ms. Cronin is a Ph.D. candidate in the Conservation Action Lab at UC Santa Cruz studying Ecology and Evolutionary Biology. Learn more about her research experiences and winning idea in her ISSF blog post and video.

In addition to the $40,000 Grand Prize, the award includes a trip, with an estimated $5,000 value, to a tuna event. ISSF will arrange for Ms. Cronin to present her proposal at a Regional Fisheries Management Organization (RFMO) event this year.

NOAA Fisheries Approves New Gear Under Small-Mesh Fisheries Accountability Measures

March 5, 2020 — The following was released by NOAA Fisheries:

Today we filed the final rule approving a new selective gear, the large mesh belly panel. This rule adds the large-mesh belly panel to the list of selective gears approved for use in the Georges Bank yellowtail accountability measure area. Gears currently approved for use in this area are the haddock separator trawl, Ruhle trawl, and rope separator trawl.

Use of the large-mesh belly panel is already allowed during normal fishing operations.

Approval of the large mesh belly panel, for the Georges Bank yellowtail area, as an additional selective trawl gear will provide the fishing industry with more flexibility in the use of trawl gear under the accountability measure, while minimizing bycatch of stocks of concern.

We denied the request to approve this gear for use in the southern windowpane accountability measure area because it did not meet the required standards for this area, and fisheries. To be approved selective gear must reduce bycatch of all species of concern, compared to the standard gear, by at least 50 percent. In the large-mesh fishery, within the windowpane accountability measure areas, the gear did not sufficiently reduce bycatch of two species of concern.

For more details please read the rule as filed in the Federal Register, and the bulletin.

North Atlantic Right Whales and the Dangers of Vessel Strikes and Entanglement

February 20, 2020 — The following was released by NOAA Fisheries:

Today, there are only about 400 North Atlantic right whales left and it is estimated that only 85 are reproductively active females. The survival and reproductive success of these remaining females and their offspring is critical to right whale recovery.

Female North Atlantic right whales are not living as long as they once did and more females than males have been reported dead in recent years. Today, females make up approximately 40 percent of the population. It is thought that the energetic stress of reproduction makes female right whales more susceptible than males to dying from entanglement or ship strike injuries.

Biologists also believe that injuries and stress caused by long-term entanglements is one of the reasons that females are calving less often. Studies suggest that more than 85 percent of North Atlantic right whales have been entangled in fishing gear at least once. About 60 percent have been entangled multiple times.

After 2017 Lawsuit, Fewer Whales Entangled As Crab Fishers Face Financial Struggle

February 14, 2020 — The Dungeness crab fishery in California recently shut down months early after a 2017 lawsuit filed by the Center for Biological Diversity (CBD) that required crab fishers to pull their gear out of the water with only 3 weeks notice. A settlement agreement was reached in March 2019, which included an early closure for the 2018-2019 Dungeness crab fishing season. Fishing gear is a serious threat to whales that live in, and migrate through, California waters. The California Dungeness Crab Fishing Gear Working Group, convened by the California Department of Fish and Wildlife (CDFW), informs regulators on ways in which to minimize entanglement risks and protect whales.

Why have there more whale entanglements recently?

According to a new paper published in the journal Nature Communications climate change could be responsible. According to lead researcher Jarrod Santora, warming events in recent years, combined with recovering whale populations cause whales to come in contact with crab fishing gear more regularly.

Crab season in California occurs between November and mid-July. Warming events in 2014-2016 caused an increase in the marine algae Pseudo-nitzschia which produce the neurotoxin domoic acid (the toxin causes shellfish poisoning in humans). In 2016, high levels of toxins delayed the crab season until March. In addition, the warmer waters changed feeding habits of humpback whales, steering them closer to shore where food was more prevalent. This perfect storm of events led to a sharp spike in observed whale entanglements in 2017. 70% of the whale entanglements reported in 2017 in the United States involved fishing gear.

NOAA Fisheries Announces Final 2020 Atlantic Surfclam and Ocean Quahog Commercial Fishery Specifications and Minimum Size Suspension for Atlantic Surfclams

February 13, 2020 — The following was released by NOAA Fisheries:

NOAA Fisheries is implementing surfclam and ocean quahog quotas for the 2020 fishing year that we previously announced as projected on February 6, 2018. There have been no overages in 2019, and there is no new biological information, so we are now finalizing the 2020 quotas. The 2020 fishing year quotas will remain 3.4 million bushels for surfclams, 5.33 million bushels for ocean quahogs, and 100,000 Maine bushels for Maine ocean quahogs.

NOAA Fisheries is also suspending the minimum size requirement for surfclams. Discard, catch, and biological data show that 22 percent of 2019 coastwide landed surfclams had a shell length less than 4.75 inches, which is less than the 30 percent trigger for a minimum size requirement. This is closer to the trigger than in prior years. Vessels are encouraged to avoid areas with a lot of clams under 4.75 inches to reduce the chance of initiating the default minimum size in 2021.

For more details, read the final rule as published in the Federal Register today and the permit holder bulletin posted on our website.

More Than $13.5 Million Awarded to Help Stranded Marine Mammals Between 2011-2015

February 12, 2020 — The following was released by NOAA Fisheries:

From 2011 to 2015, the John H. Prescott Marine Mammal Rescue Assistance Grant Program awarded more than $13.5 million to help stranded marine mammals. The funding was awarded through 160 competitive grants to Stranding Network members and collaborators in 24 states.

NOAA Fisheries sets aside a portion of Prescott funds for emergency assistance with unforeseen or catastrophic stranding events.The program provided $999,122 in emergency funds to help reimburse the Network for 15 events that required emergency support between 2011 and 2015. A review of how the funds were allocated and spent is now available in a 5-Year Report.

For the past 18 years, Congress has appropriated approximately $1 to 4 million annually to NOAA Fisheries to fund the Program. NOAA Fisheries funds eligible members of the National Marine Mammal Stranding Network and research collaborators through grants and cooperative agreements. The funding supports the recovery or treatment of marine mammals, the collection of data from living or dead stranded marine mammals for health research, and the support of facility operation costs.
