Commentary: With extinction looming, all must act to save whales
September 1, 2022

The commentary “Entanglement blame game good for wallets, not for whales” [Aug. 25] states that it is in response to “misleading and false information.” Ironically, the commentary has a measure of its own misinformation.
It would have us believe that “only two whales have ever been seen in Maine lobster gear” and that this gear has caused zero deaths and serious injuries.
However, NOAA Fisheries has stated, “We have documented Maine lobster gear on three live entangled right whales in 2002, 2003 and 2004.”
The whale referred to as having been entangled in 2004, known as Kingfisher, was born in 2003 and first seen entangled in Maine lobster gear the following year with rope wrapped multiple times around his right flipper, which embedded deeper and deeper into his flesh as the years passed. Though Kingfisher was seen every year previously, he hasn’t been sighted since 2015, when he was observed with deep, open wounds in his flipper. He is now, according to established scientific protocol, presumed dead; one of those cryptic deaths that are referred to in a 2021 scientific study that estimates that there are roughly three times as many right whale deaths occurring than have been reported.
Between 1980 and 2019, more than 1,700 right whale entanglements have been documented. Yet, due to historically lax gear-marking requirements and a low rate of gear retrieval from entangled whales, scientists can only determine where less than 2 percent of these entanglements occurred. Given the fact that the Maine lobster fishery represents the greatest density of vertical lines in U.S. waters within right whale habitat, it is very likely that many more entanglements have occurred in Maine lobster gear than have been documented.
While it is currently not possible to prove that other, additional right whale mortalities have resulted from entanglements in Maine gear, likewise, no pot/trap/gillnet fishery can prove that it is not contributing to right whale mortality, including Maine’s lobster fishery.
And we know that it is not only right whales who are being entangled by this fishery. To name just a few:
Spinnaker was a female humpback whale born in 2004. She is known to have been entangled four times, with three of those entanglements being in lobster gear, two of which occurred off of Bar Harbor. Spinnaker died in 2015 as a result of her entanglements.
Minke whales routinely get entangled and die in Maine gear. In 2020 and 2021, two minkes were entangled in Maine state gear as determined by the recently implemented gear-marking requirements.
The commentator, a fisherman himself for almost 50 years, says he has never seen a right whale, perhaps implying they aren’t in Maine waters. Yet there have been plenty of sightings and even more acoustic detections of these whales in waters that Maine lobstermen fish in.
Regarding the commentary’s citing of an increase in the right whale population, the fact remains that fewer than 340 are now estimated to remain on the planet, and they are being killed far faster than being born. And while it is true that 20 were born in the 2020-21 calving season and 15 in 2021-22, NOAA has stated in its 2022 calving season report that “given the estimated rate of human-caused mortality and serious injury, we need approximately 50 or more calves per year for many years to stop the decline and allow for recovery.”
The commentary makes some suggestions as to the most significant threats to the whale’s comeback, including deaths due to old age, but right whales are no longer living to old age, with the vast majority of deaths resulting from entanglements and vessel strikes. And as NOAA’s 2021 stock assessment report states, “The principal factor believed to be preventing growth and recovery of the population is entanglement with fishing gear (Kenney 2018).”
So, while the looming, potential extinction of the right whale cannot be solely blamed on Maine lobstermen, with vessel strikes and other fisheries also taking a heavy toll, the Maine lobster fishery is contributing to the crisis. Shouldn’t the fishery make the changes necessary so that both it, and the right whale, will continue on into the future? I, for one, think so.
