The study found that 85,000 sea turtles were reported caught by commercial fisheries worldwide over the last 20 years, but the scientists estimate that the actual number is two orders of magnitude higher than that -- in the millions.
The 85,000 figure only accounts for sea turtle bycatch that was reported, but the actual number of turtles caught is significantly higher because typically less than 1% of fleets have fishing observed and many small scale fisheries have no observer coverage at all.
The study looked at sea turtles caught by gillnets, longlines and trawls, three of the most commonly used fishing gear types. The bottom line here is that the number of sea turtles caught as bycatch is enormous. Without additional bycatch reduction and better enforcement of established protections, many sea turtle populations may go extinct.
We're celebrating a big win yesterday for loggerhead sea turtles.
In response to two petitions submitted in 2007 by Oceana, the Center for Biological Diversity and the Turtle Island Restoration Network, yesterday the National Marine Fisheries Service and the Fish and Wildlife Service issued a proposed rule to change the status of North Pacific and Northwest Atlantic loggerhead sea turtles from “threatened” to “endangered” under the Endangered Species Act.
The government also proposed listing loggerhead sea turtles around the globe as nine separate populations, each with its own threatened or endangered status.
The change in listing status means the populations are in danger of extinction and will trigger a legal requirement for proposed critical habitat, an important step in achieving improved protections for key nesting beaches and migratory and feeding habitat in the ocean.
This winter has been a doozy around the country, and not just for humans. On Tuesday, The Miami Herald published a letter to the editor from Oceana's chief scientist Mike Hirshfield on the effect of this year's harsh winter on sea turtles. Check it out:
Officials are calling this one of the worst years on record for sea turtle strandings in the United States. Approximately 2,500 sea turtles have been found wounded or dead as a result of cold-stunning in the increasing frigid waters of the Atlantic Ocean and Gulf of Mexico. Volunteers are busily scouring the coastline for sea turtles that can be rehabilitated and eventually released back into the wild, and rescue centers are becoming inundated with sea turtles fighting for survival.
To a scientist, it all makes perfect, if unfortunate, sense. Cold-blooded reptiles like sea turtles are simply unable to warm themselves in cold water. While sea turtles are commonly found in northern U.S. waters during the summer and early fall, they typically migrate to warmer climates by late October. Unfortunately, not all of them made it out before the area temperatures dropped to unbearable levels, and with a winter like we are having, it is bound to be a deadly scenario.
