PORTLAND, Maine (AP) — One of the world’s rarest whale species is having more babies this year than in some recent seasons, but experts say many more young are needed to help stave off the possibility of extinction. The North Atlantic right whale’s population numbers an estimated 384 animals and is slowly rising after several years of decline. The whales have gained more than 7% of their 2020 population, according to scientists who study them. The whales give birth off the southeastern United States every winter before migrating north to feed. Researchers have identified 15 calves this winter, the National Oceanic and Atmospheric Administration said Monday. That number is higher than two of the last three winters, but the species needs “approximately 50 or more calves per year for many years” to stop its decline and allow for recovery, NOAA said in a statement. The whales are vulnerable to collisions with large ships and entanglement in commercial fishing gear. This year’s number is encouraging, but the species remains in peril without stronger laws to protect against those threats, said Gib Brogan, senior campaign director with environmental group Oceana. The federal government is in the midst of a moratorium on federal rules designed to protect right whales until 2028, and commercial fishing groups have pushed for a proposal to extend that pause for even longer. There is still time left for more baby whales to be born this winter, but 50 is not a reasonable expectation because of a lack of reproductive females in the…This article was originally published on Mongabay
