For example, Smith (1999) showed that for menhaden reduction vessels in Virginia, vessel-specific ratios of actual annual landings to annual CDFR estimates of catch ranged from 0.
CDFR Compliance, Spotter Pilot Activity, and Fishing Days
Beginning in 1998 to the present, compliance for completing CDFR forms by snapper rig captains has been 100%, and captains provided between 318 and 482 CDFR forms annually (Table 2).
Some, but not all, snapper rig captains completed CDFR's even on days when they did not fish, noting if they did not leave the dock, or that they went to sea but did not set; hence, one completed CDFR form may not equal a "trip" with sets.
The CDFR Program for the reduction fishery was originally designed in the late 1970's as a joint state, Federal, and menhaden industry effort to provide better information on menhaden catch locations and fishing effort (Smith, 1999).
Since 2005, captains of snapper rig vessels have provided GPS coordinates of their purse-seine set location on CDFR forms.
