TEDs were later developed in the 1970s by Wil Seidel, who worked for NOAA. Even in the United States use of TEDs is not universal. Not all nations enforce the use of TEDs. The modified TSDs were similar to standard TEDs except for having fewer bars. I don't know any Bills and Teds. WiMAX, Wi-Fi and TEDS standards are part of this family. TEDs are mandatory for all shrimp trawlers. In heavily trawled areas, the same sea turtle may pass repeatedly through TEDs. In 1978, the National Marine Fisheries Service (NMFS) started to develop turtle excluder devices (TEDs). TEDS can, however, be implemented in two ways. TEDS performance is optimised for wideband data rates, wide area coverage and spectrum efficiency. Turtle excluder devices (TEDs) remove a major threat to turtles in their marine environment. Turtle Excluder Devices (TEDs) have reduced sea turtle bycatch in shrimp nets by 97 percent.
