Summary
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).

area_size_km
Unknown |

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 |
