Get Total Catch
get_total_catch.Rd
Estimate total catch from observer CPUE data
Arguments
- pot_data
NULL. Observer count pot data in the same format as the output of
load_pot_dump()
- crab_data
NULL. Observer measure pot data in the same format as the output of
load_crab_dump()
- ft_data
NULL. Fish ticket data with fields 'crab_year', 'fishery', 'effort' and whatever variables are specified in by.
- stock
NULL. Character string stock abbreviation: BSSC, WBT, EBT, BBRKC, EAG, WAG, PIGKC, SMBKC, PIBKC, PIRKC, WAIRKC.
- by
NULL. Vector of column names other than crab year, fishery, and group to use as a grouping variable.
- units
NULL. Unit of measurement, "t" or "lb". Default = "t".
Value
Data frame including crab year, fishery, grouping variables, and average weight. Average weights used for expansion to weight are only based on crab year, fishery, and sex. No other 'by' variables are included here, so that the sum of total catch by variables (i.e., sex and shell condition) will equal the total catch by sex.
Examples
get_avg_wt(pot_data, crab_data, ft_data, stock = "BBRKC")
