Fisheries that have good management practices limit the amount of turtles that are accidentally caught (i.e. trawls) and then if turtles still happen to get caught, they use techniques that put the live turtles safely back into the water. "Sea turtles caught in trawl nets, hooked in longlines, or entangled in other gears, may be stressed," according to the FAO. "Most are conscious and able to swim away after removal from the net, but some may be tired or appear lifeless. Turtles that appear lifeless are not necessarily dead. They may be comatose. Turtles returned to the water before they recover from a coma will drown. A turtle may recover on board your boat once its lungs have drained of water. This could take up to 24 hours" (FAO, 2009, p.64).
So how can you help?
