Item Identification

Title: StationEfforts
Short Name: StationEfforts
Status: In Work
Abstract:

Unions SRRECPUE and CPUE to produce all Station/Stratum-level CPUE, RPN, and RPW values. From here on when mean weight is calculated it is not averaged as length is, it is always calculated using the a and b parameters in specie_catch_codes. SRRE is short for shortraker and rougheye rockfish. In short, this is an intermediate table used for calculating CPUE and indices of abundance (RPNs and RPWs). It is catch and effort by depth strata.
