Fleet-class: Class

Description

The component of the operating model that controls fishing dynamics

Arguments

Slots

Name: Name of the Fleet object
nyears: The number of years for the historical simulation
Spat_targ: Distribution of fishing in relation to spatial biomass: F is proportional to B^Spat_targ (uniform distribution)
Fsd: Inter-annual variability in fishing mortality rate
EffYears: Vector of verticies, years at which to simulate varying relative effort
EffLower: Lower bound on relative effort corresponding to EffYears (uniform distribution)
EffUpper: Uppper bound on relative effort corresponding to EffYears (uniform distribution)
LFS: Shortest length that is fully vulnerable to fishing (uniform distribution)
L5: Shortest length corresponding ot 5 percent vulnerability (uniform distribution)
Vmaxlen: The vulnerability of the longest (oldest) fish (uniform distribution)
SelYears: Vector of verticies, index for years at which historical selectivity pattern changed. If left empty, historical selectivity is constant
AbsSelYears: Optional values for SelYears, used for plotting only. Must be of same length as SelYears
L5Lower: Optional vector of values of length SelYears, specifiying lower limits of L5 (use ChooseSelect function to set these)
L5Upper: Optional vector of values of length SelYears, specifiying upper limits of L5 (use ChooseSelect function to set these)
LFSLower: Optional vector of values of length SelYears, specifiying lower limits of LFS (use ChooseSelect function to set these)
LFSUpper: Optional vector of values of length SelYears, specifiying upper limits of LFS (use ChooseSelect function to set these)
VmaxLower: Optional vector of values of length SelYears, specifiying lower limits of Vmaxlen (use ChooseSelect function to set these)
VmaxUpper: Optional vector of values of length SelYears, specifiying upper limits of Vmaxlen (use ChooseSelect function to set these)
qinc: Average percentage change in fishing efficiency (uniform distribution)(applicable only to forward projection and input controls)
qcv: Inter-annual variability in fishing efficiency (uniform distribution)(applicable only to forward projection and input controls)
isRel: Are the selectivity parameters relative to size-of-maturity? TRUE or FALSE
