  • Description:
    To assist the Council with consideration of ping rate alternatives, an analysis of observer data was conducted to characterize the range of DGN vessel speeds while fishing. This analysis uses the 8513 observed sets over the 1990-2014 fishing seasons for which time and location data were available at the start and end of the sets. The objective is to assess the costs and benefits of increasing the DGN VMS ping rate to four times per hour relative to the status quo rate of once per hour. Higher ping rates would presumably provide a higher probability of detecting prohibited fishing activity. However, our vessel speed analysis calls into question the utility of a higher ping rate for the case of DGN fishing. [doi:10.7289/V5/TM-SWFSC-570(http://doi.org/10.7289/V5/TM-SWFSC-570)]
