In sean-rohan-NOAA/akfishcondition: Groundfish morphometric condition indicator

Pacific cod Ecosystem and Socioeconomic Profile (ESP) indicator

Description

Morphometric condition indicators based on residuals from a length-weight regression for adult and juvenile Pacific cod. Separate indicator for each region.

Usage

PCOD_ESP

Format

Eight data frames (indicator for the full region and indicator by stratum for the EBS, NBS, GOA, AI) and a character vector.

• FULL_REGION_* (data frame): Residuals for the full region

  • year: Year

  • common_name: Species common name

  • mean_wt_resid: Mean residual for the full region

  • se_wt_resid: Standard error of the indicator for the full region

• STRATUM_* (data frame): Residuals by stratum

  • year: Year

  • common_name: Species Common name

  • species_code: RACE/GAP species code

  • inpfc_stratum: INPFC Stratum

  • stratum_resid_mean: Unweighted stratum mean residual

  • n: Sample size for the stratum

  • stratum_resid_sd: Standard error of the stratum mean residual

  • weighted_resid_mean: Stratum mean Residual weighted in proportion to stratum biomass

  • weighted_resid_se: Standard error of the stratum mean residual weighted in proportion to stratum biomass

• LAST_UPDATE: Date when indicator and data were last updated.
