SDN:B07::NDT008Single net or net pair double oblique tow  
DEFINITION
  • A single net or net pair is deployed open from a moving platform to a predetermined depth. It is then returned to the surface (always open). Without returning the net to the deck, the net starts down again and fishes to the predetermined depth (usually the same depth as the first). If this pattern is repeated more than twice without returning the net to the deck, it becomes a towyo. This technique is ideal for long integrated tows, i.e. for catching patches of zooplankton. Examples of gears that can be deployed that way include ring nets, Bongo nets, Tucker trawls, and other non-opening closing nets (Wiebe and Benfield 2003, Plates 2 and 3).
