Class "Fleet"

Share:

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
