Description Usage Arguments Examples

Description

Returns the fishing quota given the biomass in fish using Fisheries mortality at Maximum Sustainable Yield with a precautionary buffer. Uses a linear projection of the last 5 years (if available; stored in the cache)

Usage

Arguments

maxage

# create a fish matrix
fish <- initpop(initial_abun=250*10^6,cells=length(BESTMPA_domain),maxage=50,rate=0.7)
# quota
quota <- estimatequota(fish,maxage=20,y=2001,tot_time=2001:2071,FMSY=0.28,FMSY_buffer=0.667)
