Deepwater Tornado Trolling (DWTT) is the working title for a novel fishing technology that comprises a looping line that is deployed vertically from small vessels, offering radically increased hook capacity compared with conventional jigging systems, and permitting fishing of pelagic species down to 300-400m depth.
Looping surface lines are a common fishing method. Looping deepwater jigs have been developed and tested by fishermen before, but the method has never been subjected to sufficient R&D efforts to overcome certain technical and operational challenges that have prevented its successful introduction in commercial fishing.
In a three-year project supported by the Research Council of Norway, Fiskevegn collaborates with SINTEF Fiskeri og Havbruk to develop Deepwater Tornado Trolling to a fully viable, commercial fishing technology.
The project is addressing hydrodynamics, technical design, fishing operations and Health-, Environment- and Safety issues. The project page can be followed at www.facebook.com/dypvannsrunddorg.
