Description Slots Objects from the Class Author(s) Examples

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

`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

(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
