NEW ORLEANS -- Four conservation groups say they'll sue the National Marine Fisheries Service because it's taking too long to analyze shrimping's effects on threatened and endangered sea turtles.
The groups contend that shrimp nets in the Gulf of Mexico kill more than 45,000 sea turtles a year and want the agency to bar shrimp trawling there until it completes its analysis.
They also want to make Louisiana enforce federal rules requiring turtle escape hatches in shrimp nets, which shrimpers say let much of their catch escape as well. State law now bars agencies from doing so.
The letter sent Wednesday began a 60-day settlement period required before suing under the Endangered Species Act.
The division of the National Oceanic and Atmospheric Administration doesn't comment about pending or active litigation, spokeswoman Allison Garrett said in an email. She said the analysis is underway.
"NOAA has known there is a problem with the number of sea turtles stranding and being killed in the Gulf since the spring of 2010," said Eric Bilsky, an attorney with Oceana, one of the groups involved. "And so, when we are coming on the spring of 2014, 'We're working on it' is not enough.
"We need to know when it's going to get done and we need it done soon. And we need the analysis not just to be an analysis; we need to know what specific steps NOAA is going to take to make sure that sea turtles are not getting killed anymore."
The Center for Biological Diversity, the Turtle Island Restoration Network and the Sea Turtle Conservancy joined the letter of intent sent Wednesday to Commerce Secretary Penny Pritzker and three NOAA officials.
