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.

First Long Term Acoustic Study Tunes Into Cook Inlet Beluga Whale Foraging Ecology

February 19, 2020 — The following was released by NOAA Fisheries:

The first continuous multiyear acoustic monitoring effort across Cook Inlet provides the most comprehensive description of beluga whale seasonal distribution and feeding behavior to date.

This knowledge is critical for understanding and managing potential threats impeding recovery of this endangered population.

“Cook Inlet belugas were listed as endangered in 2008. Despite protective measures, the population continued to decline,” said Manuel Castellote, NOAA Fisheries affiliate/University of Washington/Joint Institute for the Study of the Atmosphere and Ocean biologist who led the study. “We undertook this study to provide information that managers needed to develop an effective recovery strategy.”

Castellote worked in partnership with the Alaska Department of Fish and Game to develop a passive acoustic monitoring program. It recorded beluga movements and foraging behavior within their critical habitat year-round over five years.

“Summer beluga distribution has been well studied, especially in the upper inlet. But information on foraging behavior during the rest of the year was basically nonexistent,” Castellote said. “That knowledge is essential to identify threats impeding the whales’ recovery.”

Listening for Right Whales in the Gulf of Maine

February 18, 2020 — The following was released by NOAA Fisheries:

Two passive acoustic data collection efforts are underway in the Gulf of Maine to gather information on North Atlantic right whales. One will deploy fixed archival-acoustic recorders mounted on the ocean bottom for a specific period of time. The other will use autonomous underwater vehicles called gliders, equipped to record acoustic information and report it back in near real-time.

“Real time monitoring provides the opportunity for direct conservation action through alerting vessels to the presence of endangered whales and to slow down to avoid striking the whales, while archival monitoring helps build a long-term 24/7 picture of their presence,” said Sofie Van Parijs, who leads the Passive Acoustic Research Group at the Northeast Fisheries Science Center.

“These new efforts will support routine passive acoustic monitoring of North Atlantic right whales and other baleen whale species throughout priority areas, and improve our understanding of changes in their movement patterns,” she said.

Right whales have changed their historic migration patterns in recent years, and tracking them is a difficult task.

Like most whales, this species does not spend much time on the ocean surface where they can be seen by researchers during aerial or ship-based surveys. Sound is the whale’s primary means of communicating, so if they are present in an area, they are probably making sounds. Underwater microphones can detect those sounds and even report back to researchers in near real-time.

Passive acoustic monitoring – detecting and recording sounds, in this case underwater – offers scientists another tool for learning about whale behavior and migration patterns. Advanced underwater microphones or hydrophones and autonomous underwater vehicles can detect and record those sounds. Computer programs help differentiate species and indicate time, direction and location.

These instruments can remain in the water continuously for months at a time. Along with visual sightings made from ships and aircraft, the sound recordings are revealing information about where and when whales of various species are present.

Maine wants more credit from feds for efforts to save whales

February 14, 2020 — Maine’s top marine official has told the federal government that his state deserves more credit for the efforts it has made to try to save an endangered species of whale.

Maine is tasked with coming up with new regulations that make the oceans safer for North Atlantic right whales, which number only about 400 in the world. The proposed new protections place new restrictions on the lobster fishing business, which is critical to Maine’s economy and heritage.

The National Oceanic and Atmospheric Administration informed Maine in January that its proposal to protect the whales doesn’t go far enough.

But Patrick Keliher, the commissioner of the Maine Department of Marine Resources, sent a letter to NOAA on Wednesday that outlined numerous existing and additional proposed protections that he said play a key role in protecting the whales.

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.

Maine Lobstermen Dismayed By Fed’s Push For More Gear Changes To Protect Endangered Whale

February 14, 2020 — Maine’s top fisheries regulator is telling his federal counterparts the state’s lobster fleet deserves more credit for its efforts to reduce the risk of fishing gear entanglements with the endangered North Atlantic right whale.

Department of Marine Resources Commissioner Patrick Keliher revealed this week that the National Oceanic and Atmospheric Administration told him that Maine’s proposed gear changes, including a reduced number of  vertical ropes in offshore waters, are insufficient.

In a letter sent Wednesday, Keliher tells NOAA that it is overlooking other whale protection measures that the state has taken in the past and is proposing for the future. “It needs to be taken into consideration: it’s not part of any calculations they have on the books right now,” he says.

Keliher met last night with the state Lobster Advisory Council, which includes fishermen from each of the state’s seven lobster management zones.

He says Maine should get credit for replacing floating rope lines that pose a big hazard for the whales with safer, sinking lines, and for Maine’s proposal to require inshore boats to weave weak, breakaway links into their lines.

Maine counters NMFS rejection of right whale plan

February 14, 2020 — Maine officials said that the National Marine Fisheries Service’s rejection of its submitted right whale plan didn’t take enough of the state’s efforts into account.

The NMFS rejected the state’s plan via letter earlier this week. According to NMFS, the state’s plan only reduces risk to right whales by roughly 52 percent, short of the 60 percent that the Take Reduction Team was aiming for.

Maine whale protection plan doesn’t go far enough, feds say

February 13, 2020 — Federal regulators don’t believe a Maine plan to reduce risk to endangered whales goes far enough, and that means fishermen in the state could face more restrictions.

Maine officials submitted a plan to the federal government designed to meet a requirement to better protect rare North Atlantic right whales from entanglement in lobster fishing gear. The whales number only about 400 and can die if ensnared in the gear, which is used to trap one of Maine’s best known and most valuable natural resources.

The National Oceanic and Atmospheric Administration notified the state in a Jan. 10 letter that its proposed package of measures would result in no more than a 52% reduction in risk to the whales. The required goal is 60%, said the letter, which was written by Michael Pentony, regional administrator for NOAA’s National Marine Fisheries Service’s Greater Atlantic Regional Fisheries Office.

Maine says its plan to protect whales from lobster gear is better than feds think

February 13, 2020 — Maine believes its right whale protection plan isn’t getting enough credit for reducing risk to the critically endangered species.

The state Department of Marine Resources believes that its right whale plan, with its range of lobster fishing restrictions meant to avoid gear entanglements, clocks in right around the 60 percent risk reduction target sought by the National Marine Fisheries Service.

Federal regulators – who  determined that the state plan reduced risk by just 52 percent – failed to give Maine credit for all its proposed protection measures, as well as those enacted since the last federal right whale review in 2014, Marine Resources Commissioner Pat Keliher said Wednesday.

Keliher spelled out his concerns with the federal evaluation of Maine’s plan during a meeting with members of the Lobster Advisory Council Wednesday evening and in a letter to the National Marine Fisheries Service that he sent earlier in the day asking for additional risk reduction credit.

Maine’s plan to protect whales falls short, regulators say, raising prospect of federal rules

February 12, 2020 — Maine’s plan to protect right whales does not go far enough to reduce the risk of entanglement in lobstering gear, according to federal regulators.

The National Marine Fisheries Service has concluded that Maine’s plan to use a combination of weak rope and a 25 percent reduction in the number of buoy lines in state waters achieves, at best, a 52 percent risk reduction, while federal regulators are demanding a 60 percent reduction.

“Because your proposal does not meet the 60 percent risk reduction target, we will be obligated to consider additional measures through our federal rulemaking,” said Michael Pentony, regional administrator of NMFS’s Greater Atlantic Regional Fisheries Office.
