Blog Tags: Fishing Gear Entanglement
One of the dangers whales face is entanglement in fishing gear such as longlines, traps and pots. When officials become aware of these events, disentanglement teams are sent out to assess the situation and free the whales whenever possible.
Some researchers have worried that the stress of being caught in fishing gear and the prolonged exposure to humans during the rescue might permanently affect the whales, possibly hindering their ability to reproduce. But this birthing season, three formerly entangled right whales were spotted and photographed with their calves, The Washington Post reports.
Equator, so named for the rope scar around her middle, was seen with her newborn near Little Saint Simon’s island off the Georgia coast.
Over the past week, the New England Aquarium pulled off the dramatic rescue, rehabilitation and release of a 655-pound, 7-foot leatherback sea turtle which had stranded on Cape Cod (as seen in the video above). The prehistoric-looking reptile was found suffering from dehydration and shock with a significant portion of its left-front flipper missing, an injury the Aquarium said was consistent with entanglement in fishing gear, a sadly common occurrence with these severely threatened animals.
Leatherbacks are long-distance swimmers, using their giant paddle-like flippers to propel them over vast distances. This turtle from the Western Atlantic population travels all the way from the white sandy beaches of the Caribbean to the jellyfish-rich waters of New England each year, and may even swim as far north as Newfoundland. After a weekend being nursed back to health by aquarium staff, this beleaguered leatherback, which veterinarians estimated to be around 25 to 30 years old, was released off of Cape Cod on Sunday.
If the turtle survives, it will be a cheerful chapter in an increasingly desperate story about a species that has survived for a hundred million years but faces extinction in the coming decades. As many as 2,300 leatherbacks may have died at the hands of commercial fishing activities each year throughout the 1990s. Aside from entanglement in fishing gear, many turtles also face threats from poaching and countless die from ingesting plastic. Leatherbacks, whose throats are lined with backward-pointing spines to prevent swallowed jellyfish from escaping, are especially vulnerable to choking on plastic bags, which they mistake for their favorite prey.
But there is hope for the leatherback sea turtle. In 2007, Oceana petitioned the federal government to designate critical habitat for off the U.S. West Coast, where Pacific populations have plummeted by as much as 80% in recent decades. In response, earlier this year, The National Marine Fisheries Service finalized protection of almost 42,000 square miles of protected ocean habitat off the shores of Washington, Oregon and California for the endangered turtle. Turtles arrive in these areas each year after swimming as far as 6,000 miles across the open ocean from nests in Indonesia. This is the first permanent safe haven designated for leatherbacks in U.S. waters. The National Marine Fisheries Service has yet to designate similar critical habitat for loggerhead turtles in the Atlantic or Pacific Oceans even though they are required by law to do so.
Help Oceana continue to fight for this incredible animal, the largest turtle and one of the largest living reptiles on Earth.
Ever visited a sea turtle sick ward? I have, and it's an enlightening, if sad, experience. Here’s your chance to do so virtually. Oceana supporter and actress Lauren Norman visited a Florida sea turtle hospital and science center and made the video below about what she learned.
Lauren discovers the main reasons sea turtles end up in rehab (fishing gear, boat propellers and cold stunning) and what can be done to protect sea turtles from ending up tangled in fishing gear, such as the use of turtle excluder devices.
Inspired by Lauren’s video? Now take action to protect sea turtles by telling President Obama that the ancient mariners need comprehensive protections in U.S. waters. Thanks to Lauren and all of you for helping protect sea turtles!
