Fleet-class: Class '"Fleet"'

Description Objects from the Class Slots Methods Author(s) Examples

Description

The component of the operating model that controls fishing dynamics

Objects from the Class

Objects can be created by calls of the form new("Fleet", OM).

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
