SDN:B07::NDT017Multiple net/multiple cod-end system stratified oblique tow  
DEFINITION
  • Multiple nets are deployed on a single frame with opening and closing capability. In the case of a system like MOCNESS, the first net (0) is deployed to the bottom depth, open. Once at the bottom the zero net is closed, at the same time opening the second (net 1) net. This net is hauled to a predetermined depth and then closed while the next net is opened. The procedure continues until the final predetermined depth is reached (normally the surface). For systems like the Multinet, the system can be deployed without a net open and the first net is opened at depth. This deployment strategy can also be done with a single net with multiple a cod-end system. Examples of gears that can be deployed that way include MOCNESS, BIONESS, Multinet, other multiple net opening/closing systems (Wiebe and Benfield 2003, Plates 28-31).
