The component of the operating model that controls fishing dynamics

`Name`

Name of the Fleet object. Single value. Character string.

`nyears`

The number of years for the historical 'spool-up' simulation. Single value. Positive integer

`Spat_targ`

Distribution of fishing in relation to spatial biomass: fishing distribution is proportional to B^Spat_targ. Uniform distribution lower and upper bounds. Real numbers

`EffYears`

Years representing join-points (vertices) of time-varying effort. Vector. Non-negative real numbers

`EffLower`

Lower bound on relative effort corresponding to EffYears. Vector. Non-negative real numbers

`EffUpper`

Upper bound on relative effort corresponding to EffYears. Vector. Non-negative real numbers

`Esd`

Additional inter-annual variability in fishing mortality rate. Uniform distribution lower and upper bounds. Non-negative real numbers

`qinc`

Average percentage change in fishing efficiency (applicable only to forward projection and input controls). Uniform distribution lower and upper bounds. Non-negative real numbers

`qcv`

Inter-annual variability in fishing efficiency (applicable only to forward projection and input controls). Uniform distribution lower and upper bounds. Non-negative real numbers

`L5`

Shortest length corresponding to 5 percent vulnerability. Uniform distribution lower and upper bounds. Positive real numbers

`LFS`

Shortest length that is fully vulnerable to fishing. Uniform distribution lower and upper bounds. Positive real numbers

`Vmaxlen`

The vulnerability of fish at

`[email protected]`

. Uniform distribution lower and upper bounds. Fraction`isRel`

Selectivity parameters in units of size-of-maturity (or absolute eg cm). Single value. Boolean.

`LR5`

Shortest length corresponding ot 5 percent retention. Uniform distribution lower and upper bounds. Non-negative real numbers

`LFR`

Shortest length that is fully retained. Uniform distribution lower and upper bounds. Non-negative real numbers

`Rmaxlen`

The retention of fish at

`[email protected]`

. Uniform distribution lower and upper bounds. Non-negative real numbers`DR`

Discard rate - the fraction of caught fish that are discarded. Uniform distribution lower and upper bounds. Fraction

`SelYears`

(Optional) Years representing join-points (vertices) at which historical selectivity pattern changes. Vector. Positive real numbers

`AbsSelYears`

(Optional) Calendar years corresponding with SelYears (eg 1951, rather than 1), used for plotting only. Vector (of same length as SelYears). Positive real numbers

`L5Lower`

(Optional) Lower bound of L5 (use

`ChooseSelect`

function to set these). Vector. Non-negative real numbers`L5Upper`

(Optional) Upper bound of L5 (use

`ChooseSelect`

function to set these). Vector. Non-negative real numbers`LFSLower`

(Optional) Lower bound of LFS (use

`ChooseSelect`

function to set these). Vector. Non-negative real numbers`LFSUpper`

(Optional) Upper bound of LFS (use

`ChooseSelect`

function to set these). Vector. Non-negative real numbers`VmaxLower`

(Optional) Lower bound of Vmaxlen (use

`ChooseSelect`

function to set these). Vector. Fraction`VmaxUpper`

(Optional) Upper bound of Vmaxlen (use

`ChooseSelect`

function to set these). Vector. Fraction`CurrentYr`

The current calendar year (final year) of the historical simulations (eg 2011). Single value. Positive integer.

`MPA`

(Optional) Matrix specifying spatial closures for historical years.

Each row should contain year index (e.g 10 for 10th historical year) followed by fraction of area closed to fishing for each area. i.e. each row represents a change and the number of columns is nareas + 1. The spatial closures are assumed to remain in place for the future projections unless changed by a MP. Default (if left blank) is all areas are open to fishing in historical period.

Objects can be created by calls of the form `new('Fleet')`
