Fleet-class: Class 'Fleet'

Description

The component of the operating model that controls fishing dynamics

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)

Esd

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 to 5 percent vulnerability (uniform distribution)

Vmaxlen

The vulnerability of the longest (oldest) fish (uniform distribution)

LR5

Shortest length corresponding ot 5 percent retention (uniform distribution)

LFR

Shortest length that is fully retained (uniform distribution)

Rmaxlen

The retention of the longest (oldest) fish (uniform distribution)

DR

Discard rate - fraction of caught fish that are discarded (must be <= 1) (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

CurrentYr

The current calendar year (final year) of the historical simulations (e.g. 2011)
