Why can’t turtles swim along and be emptied when the trawl net is pulled up?
A4: When turtles are active, they need to return to the water’s surface every few minutes in order to breathe. Trawl nets drag along and near the bottom rather than surface of the water, for periods of 30 minutes or more. When resting or sleeping, turtles can remain under water without breathing for about two hours, however, most turtles are actively swimming when they are scooped up into trawl nets.
