SDN:B07::NDT021Multiple net/multiple cod-end system oblique stepped continuous horizontal tow
- Multiple nets are deployed on a single frame with opening and closing capability. The first net (0) is deployed to a predetermined depth, open. Once at that depth, that net is closed, at the same time opening the second (net 1) net. This net is towed horizontally for some distance then quickly hauled to some shallower depth (2) where the net is closed and the next net is open. That net is then towed horizontally for some distance then hauled quickly to some shallower depth and closed, the next net open, and so on until all the nets have been fished horizontally over a series of fixed depths. This deployment strategy can also be done with a single net with a multiple cod-end system. Example of gears that can be deployed that way include the MOCNESS, the BIONESS, the Multinet or other multiple net opening/closing systems (Wiebe and Benfield 2003, Plates 28-31).
