Wildlife Experts Worry About Lack of Newborn Right Whales
Wildlife researchers in Georgia and Florida are concerned about the population of endangered whales. The winter birthing season just ended, but no newborn sightings have been reported.
There are currently an estimated 450 North Atlantic right whales.
Since December, researchers have been looking for newborns off the coasts of Georgia and Florida. Each winter, pregnant female whales migrate to the area to give birth in warmer waters, usually from December to late March.
Barb1 Zoodsma oversees2 the right whale recovery program for the National Marine3 Fisheries Service in the southeastern United States.
“It’s a pivotal moment for right whales,” Zoodsma said. “If we don’t get serious and figure this out, it very well could be the beginning of the end.”
Last year, the number of right whale deaths was greater than the number of births. In the U.S. and Canada, there were 17 right whale deaths recorded, while only five right whale births were reported.
Research on the whales have found that most female right whales are only living only to half their expected years. Research on the whales that gave birth last year showed that they were having babies for the first time in seven or eight years. That is more than double the usual time between pregnancies4.
Philip Hamilton is a scientist at the New England Aquarium5 in Boston. Hamilton has studied right whales for 30 years.
He said, “Following a year of such high mortality, it’s clear the population can’t sustain that trajectory6.”
This is why researchers are saying more needs to be done to protect the species.
In January, conservationists like the Defenders7 of Wildlife and the Center for Biological Diversity took legal action against the U.S. government. They argued that it failed to protect right whales as ordered by the Endangered Species Act. The Center called for more restrictions8 on the fishing industry.
Philip Hamilton suggests that placing speed restrictions on ships in certain areas will help protect the whales further.
“It all has to happen quickly,” he said. “We can’t handle waiting 10 or 20 years.”
Examinations of the 17 bodies showed that a ship had hit at least four of the right whales. Another two of the deaths were caused by fishing gear entanglement9.
As a result, some fishermen are testing equipment designed to bring traps to the surface. Others are experimenting with equipment that will prevent large whales from being trapped in the first place.
Net trapping is not always deadly. But, scientists suspect that a trapping incident causes emotional effects that could harm a pregnancy10.
Nonetheless, there is still hope for the right whale population.
As the whales return to their feeding areas this spring, scientists plan on looking for newborn stragglers.
Charles “Stormy” Mayo is a right whale researcher in Provincetown, Massachusetts at the Center for Coastal11 Studies. Mayo remains12 hopeful about the possibility that right whale babies were born this season a little further north, as far up as Virginia’s coast.
In Cape13 Cod14 Bay last year, two calves15 were seen that had not been seen earlier in the south.
It is also possible that after a light birthing season this year, a baby boom could happen next year. This has been happened before. In 2000, only one newborn birth occurred while the following year there were 31 births.
Zoodsma said, “I do think we can turn this around. But it’s sort of like, what’s our willpower to do so? This is a time for all hands on deck.”
