The fisheries Service has linked these “strandings” to drowning in shrimp fishing nets. Despite this rise in sea turtle strandings and the devastating impacts of the 2010 Deepwater Horizon oil disaster, the conservation groups say the agency has not fulfilled its duty to protect the imperiled animals from harm.

Recent federal reports show the number of drownings in the Gulf alone likely exceeds the allowable take for the Gulf and Atlantic shrimp fisheries combined, and also indicate significant noncompliance with existing regulations. The lawsuit aims to force the fisheries service to complete the required studies and adopt interim measures to protect turtles.

“Sea turtles in the Gulf of Mexico are still reeling from the impacts of last year’s oil spill, and they simply can’t withstand the chronic threat of drowning in shrimp nets,” said Jacyln Lopez, an attorney at the Center for Biological Diversity. “The government’s own data show that record numbers of sea turtles have perished in the Gulf of Mexico this year, yet the Fisheries Service has not taken protective measures to prevent sea turtles from dying in the shrimp-trawl fishery.”

Shrimp trawling has for many decades been the primary threat to sea turtle survival in the U.S., and turtles in the Gulf of Mexico may be more vulnerable now to drowning in shrimp nets as a result of the BP spill and cleanup efforts. The shrimp trawl fishery incidentally captures and kills thousands of threatened and endangered sea turtles each year. “Turtle excluder devices” can help prevent turtles from drowning in the nets, but not all shrimpers are required to use them and still others simply don’t comply with existing regulations.
