Study: Fish gear entanglements stunting endangered right whales growth

North Atlantic right whales – which can weigh as much as 70 tons – pay a high price for dragging hundreds of pounds of rope and fishing gear for thousands of miles for days or months, sometimes years, according to a study published today in the journal “Current Biology.” Lobster-gear entanglements are stunting the growth of the endangered species, the study concluded.  Researchers from NOAA, the Woods Hole Oceanographic Institution, New England Aquarium in Boston and Oregon State University analyzed photographs from aerial surveys and drones to determine that right whales are exhibiting the stunted growth due mostly to entanglement and that females appear to be producing smaller calves.

Right whale protections: Will they save this endangered species in 2021

Editor s note: This is part of a series of 10 stories on a variety of topics that take a look back at 2020 and forward to 2021. Many policies and practices were changed or adjusted because of the pandemic or other disruption  and we look at how those changes will shape the future.  For North Atlantic right whales, the most endangered great whale  and marine mammal    on Earth, the good news for the new year started early, with the birth of three calves in the fall. But a fourth calf washed up dead on a North Carolina beach in late November, believed to have died of natural causes soon after birth.
