Summary

Abstract

Relative population numbers and weights and catch per unit effort (CPUE) by geographic areas. All data in this table is calculated from raw catch data. No data is overwritten with fixed values.Data from all strata with area sizes are included (including stratum 2b (151-200 m).

Description

Entity Information

Data Attribute / Type Description
Year
Unknown 		Year of survey
Survey
Unknown 		Country that conducted survey (Japan or United States)
Council_sablefish_management_area_ID
Unknown 		Auto generated
Council_sablefish_management_area
Unknown 		Management areas: Bering Sea, Aleutian Islands, Western Gulf of Alaska, Central Gulf of Alaska, West Yakutat, and Southeast/Outside
Geographic_area_name
Unknown 		Smaller areas within the management areas dictated by depth and habitat
area_code
Unknown 		Auto generated
Species_Code
Unknown 		RACE species code
species
Unknown 		Species common name
area_size_km
Unknown 		size in square km of the each strata within a geographic area
CPUE
Unknown 		Average CPUE (catch in number per skate of 45 hooks) scaled to each geographic area. Western Aleutian Islands are extrapolated with hard-coded ratios of historic survey catch for the Western and eastern Aleutians for sablefish only, for United States only. All values are calcualted; none are hard coded numbers prom previously publishe reports (see areaeffortsd fixed for that).
RPN
Unknown 		Relative population number (RPN) for each Geographic Area and stratum. RPN is an index of abundance and not an absolute estimate of the total number of fish. It is calculated for each stratum at each station by multiplying the CPUE for each stratum at each station by the area of the stratum in the Geographic Area. The RPN for a stratum in a Geographic Area is then calculated by averaging the RPNs for all stations within each stratum in a Geographic Area. A null value means there were no fish caught.
RPW
Unknown 		RPW (relative population number) for each strata in each geographic area, values are hard coded for previously published values from Japanese surveys for each geographic area. Western Aleutian Islands are extrapolated with hard-coded ratios of historic survey catch for the Western and eastern Aleutians for sablefish only, for United States only.
mean_length
Unknown 		mean length (cm) for species which have lengths taken in each geographic area
mean_weight
Unknown 		mean weight (kg) for species which have lengths taken in each geographic area
LastModifiedDate
Unknown 		Last date where data was calcualted and the data in this table was updated.
