18988 ATL_HOOKS_PER_SEGMENT Entity Published / External 18964 AFSC/FMA/NPRB Alternative Catch Monitoring Table and Column Definitions Data Set Completed Stock assessment authors for sablefish (and potentially for P.cod) use catch-per-unit-effort information in their models. A key component of this is the spacing of the hooks on the gear. Every year, we issue a special project where the observers measure the spacing of the hooks on a few segments of gear. That special project has been absorbed into the standard data set for 2010. This entity represent the hook count and hook spacing measurements for a segment of gear.

NUMBER 2 CRUISE NUMBER 22 Yes Yes 8 0 Active Sequence generated by Norpac and supplied to the observer as an unique identifier for an observer cruise record. NUMBER NPRB_1017.ATL_HOOK_COUNT_SET 3 PERMIT VARCHAR2 6 Yes Yes Active Unique Code identifying a vessel or Processor - inherited from the NORPAC data set and created by the RAM division in Juneau VARCHAR2 NPRB_1017.ATL_HOOK_COUNT_SET 4 SET_SEQ NUMBER 22 Yes No 38 0 Active Sequence generated unique identifier of a hook spacing set. NUMBER NPRB_1017.ATL_HOOK_COUNT_SET 5 SEGMENT_NUMBER NUMBER 22 No No 3 0 Active This attribute represents a user defined integer identifying a unit of line for counting and spacing hooks. It must be unique within a hook_count_set. NUMBER 6 NUMBER_OF_HOOKS NUMBER 22 Yes No 8 0 Active Number of hooks as determined by the observer for this segment, contained within a counted set. NUMBER 7 HOOK_SPACING_IN_CM NUMBER 22 No No 4 0 Active Spacing between hooks on a segment.
