Summary of Catch Estimates from the Marine Recreational Fisheries Statistics Survey

Description

Species-specific estimates of harvest weight and numbers of fish, released fish, and total catch are summarized for any combination of year(s), state(s), bimonthly wave(s), fishing mode(s), and fishing area(s) from the Marine Recreational Fisheries Statistics Survey (MRFSS) data.

Usage

catchseries(estdir = NULL, species = NULL, state = NULL,
 byst = 1, wave = NULL, bywave = 0, mode = NULL, 
 bymode = 0, area = NULL, byarea = 0, styr = NULL,
 endyr = NULL)

Arguments

estdir the path and main directory (in quotes) under which catch/effort sub-directories are stored.
species 10-digit NODC species code. A complete list of species codes is provided at the MRFSS website
state state(s) code of data to include. A complete list of state codes is provided at the MRFSS website. Atlantic and Gulf States: 23= ME, 33= NH, 25= MA, 44= RI, 9= CT, 36= NY, 34= NJ, 10= DE, 24= MD, 51= VA,37= NC, 45= SC, 13= GA, 12= FL (121= East FL, 122= West FL), 1= AL, 28=M S, and 22= LA. Any combination of states can be included in c(). North Atlantic= c(9, 23, 25, 33, 44), Mid Atlantic= c(10, 24, 34, 36, 51), South Atlantic= c(13, 37, 45, 121), Gulf of Mexico= c(1, 22, 28, 122).
byst numeric value. 0 = combine data from states, 1 = show data on state-by-state basis. Default=1
wave bimothly wave(s) of data to include. Bimothly Waves: 1= Jan-Feb, 2= Mar-Apr, 3= May-Jun, 4= Jul-Aug, 5= Sept-Oct, 6= Nov-Dec. Any combination of waves can be included in c().
bywave numeric value. 0 = combine data across waves, 1 = show data on wave-by-wave basis. Default=0
mode the fishing mode(s) of data to include. Valid codes will depend on year. Years 1982-2004: 3= Shore, 6= Party & Charter Boats, and 7= Private & Rental Boats. Years 2005-present: 3= Shore, 4= Party Boat, 5= Charter Boat, and 7= Private & Rental Boats. Any combination of modes can be included in c().
bymode numeric value. 0 = combine data across modes, 1 = show data on mode-by-mode basis. Default=0
area area code of data to include. Area codes: 1= State Territorial Seas (Ocean<=3 mi excluding Inland), 2= Exclusive Economic Zone (Ocean>3 mi), 3= Ocean <=10 mi West FL and TX, 4= Ocean > 10 mi West FL and TX, 5= Inland, 6= Unknown. Any combination of areas can be included in c().
byarea numeric value. 0 = combine data across areas, 1 = show data on area-by-area basis. Default=0
styr the starting year of data to include.
endyr the ending year of data to include.

Details

Catch/effort estimates must be extracted using function extractMRFSS before summarization. Harvest, release and weight estimates are always summed by year regardless of whether other factors (state, mode, wave, and area) are aggregated or not. Additional statistics (standard error and proportional standard error) are provided for each estimate. Definition of estimates can be found at the MRFSS wesbite.

Value

Details a list element summarizing the selected arguments.
Results a list element containing the table of summary statistics (i.e., estimate, standard errors, and proportional standard errors) of harvest and release numbers and harvest weight (kg).
