What is a TED?

A Turtles Excluder Device (TED) is a device inserted into shrimp trawl nets to reduce accidental bycatch of turtles.

TEDs consist of a frame, usually oval, with vertical bars set at precise spacing that allows shrimp and fish to pass through and collect in the net while turtles and other large objects are forced out through a flap system. These TEDs are fixed within a trawl net and allow a fishermans catch to be retained while turtles are excluded.

TEDs can create benefits for both fisherman and the marine environment by reducing bycatch, fuel costs and damages, improving catch quality and increasing sustainability of fisheries and marine diversity.

TEDs were first developed in the USA and are now used in regions all over the world. Learn more about TED usage, regulations and Shrimp fisheries with our interactive map.

How much does a TED cost?

Approximately RM500 or USD122

What materials are used to make a TED?

TEDs are usually constructed from steel, aluminium rod or fiberglass.

Do other types of boats use a TED?

No. TEDs are only used for Shrimp trawl vessels.

Can TEDs reduce the number of total catch?

There can be a minimal impact on catches while using TEDs. However, its difficult to measure as catch size will vary day to day. In areas of Malaysia, trials showed no major differences in total catch quantity but differences in catch composition, where nets using TEDs had smaller size shrimp than nets without TEDs. In other trials around the world, shrimp catches have varied only by -2.1% to +6.14%. Although catches may decrease slightly, damage to nets, fuel costs and bycatch can be reduced which will save fisherman money in the long term.


Do TEDs exclude other species besides turtles?

Yes, they do. They also exclude other objects such as rubbish or wood. Watch the video below to see it in practice!


Are there any other names for TEDs?

Yes, TED is the acronym commonly used for Turtle Excluder (or Eclusion Device), but can also stand for: Trawl efficiency devices, Trawl exclusion device, Trash eradication devices and Trash elimination devices.


Why do we need to protect sea turtles?

Sea turtles play an extremely important ecological role by acting as a substrate, transporting organisms attached to them to different habitats and helping to transfer significant quantities of nutrients to nutrient poor nesting grounds. They can also provide a huge revenue for countries through tourism and act as a indicator species, reflecting the conditions of ecosystems.
