These regulations remain in effect until Sept. 7. Meanwhile, Mossbacher heads back to federal court to justify the new regulations. So, stay tuned for the next installment of 'As the TED ; From North Carolina to Texas, fishermen say TEDs are losers when it comes to shrimp. They claim all of the dif- ferent TED designs expel turtles and lots of shrimp too. But Sea Grant agent Jim Bahen and Varnamtown netmaker Steve Parrish have been hard at work to correct this flaw. The duo began their work with miniature TEDs in the Navy's flume tank—a test tank for ship and submarine designs. After hours of testing and yards of videotape, Bahen and Parrish came back to North Carolina with a better idea of how TEDs worked underwater. That's when the changes began. Parrish modified his own design, the Parrish soft TED, and another design that used a metal grid to deflect the turtle out of the net. Then Parrish and Bahen headed to Georgia for a real test aboard The Georgia Bulldog, a research and testing vessel operated by Georgia Sea Grant. The TEDs were installed one at a time in a 65-foot, two-seam shrimp net, a standard net used for brown shrimp in North Carolina. As a control, no TED was placed in the other net towed by the trawl. In nine tows alongside Georgia's shrimp fleet, the TED nets either netted as many or more shrimp than the control net without the TEDs. "The modifications reduced shrimp loss significantly," Bahen says. To prove how well the modified TEDs worked, Bahen placed an underwater video camera in the net. He now has footage that shows how the TEDs work underwater, how they reduce shrimp loss and how they expel Bahen is assembling the footage into a video that he will have available to show fishermen early this fall.
