SDN:B07::NDT022Multiple net/multiple cod-end system discontinuous horizontal tow  
DEFINITION
  • Multiple nets are deployed on a single frame with opening and closing capability or this type of deployment also applies to a single net with a multiple cod-end system. The net system is deployed to a predetermined depth with the first net either open or closed. At depth, the first net is opened (if it was closed) or closed (if it was open) and the next net opened in this case. The open net is towed horizontally for some distance and then closed. The next net is NOT open upon the previous net's closing and the system travels some distance at the same depth before another net is opened. This sequence continues until all nets are fished at the specific required depth intervals. In this deployment configuration, there are intervals between nets that are NOT sampled. Examples of gears that can be deployed that way include MOCNESS, BIONESS, Multinet, multiple net opening/closing systems; cod-end serial samplers such as LHPR, ARIES (see Wiebe and Benfield 2003, Plates 27B-31C).
