Description Usage Arguments Examples
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)

|
maxage |
Maximum age considered in |
y |
current year |
tot_time |
The time over which the model is run including spin-up time |
FMSY |
Fisheries mortality at Maximum Sustainable Yield |
FMSY_buffer |
quota set to fraction of FMSY as per precautionary principle |

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)
