Attribute Summary

Score Req'd? PKey? » Name Data Storage Type Description
100 No No Depth_ID Unknown auto generated
100 No No Haul_Position_ID Unknown auto generated
100 No No hachi Unknown Hachi(also called skate) number. Each hachi gets a number at each station starting with 1 and numbered sequntially.
100 No No depth_time Unknown time at which hachi was hauled
100 No No depth Unknown depth taken at haul-back for every 5th skate and when there is a depth stratum change
100 No No intrpdep Unknown depth interpolated for hachi's where no depth was recorded (recorded for every 5th skate)
100 No No depth_stratum_id Unknown Autogenerated ID
100 No No baited Unknown number of hooks with bait only at haul-back
100 No No ineffective Unknown number of hooks that were not fishing effectively at haul-back because they were snarled with other hooks, bent, broken, or missing
100 No No rpn_filter Unknown If there is a value here the hachi is not being used for RPN calculations. This is mainly used for filtering out hachi's when there was killer whale depredation.
100 No No depth_stratum_id2 Unknown Autogenerated ID
