Class 'Rec'

An object for storing the MP recommendations

Slots

TAC

A numeric value with the TAC recommendation

Effort

A numeric value with the effort recommendation as a fraction of current (nyear) fishing effort

Spatial

A boolean vector of length 'nareas' specifying if area is open (1) or closed (0) to fishing

Allocate

A boolean value describing if effort should be re-allocated from close to open areas

LR5

smallest length at 5 per cent retention - in absolute units - i.e same units as Linf and L50

LFR

smallest length at full retention - in absolute units - i.e same units as Linf and L50

HS

upper harvest slot (no retention above this) - in absolute units - i.e same units as Linf and L50

Rmaxlen

retention of the largest size class - fraction between 0 and 1

L5

smallest length at 5 per cent selection - in absolute units - i.e same units as Linf and L50

LFS

smallest length at full selection - in absolute units - i.e same units as Linf and L50

Vmaxlen

selection of the largest size class - fraction between 0 and 1

Fdisc

fraction of discarded fish that die - fraction between 0 and 1

DR

Discard rate - the fraction of caught fish that are discarded

Misc

An empty list that can be used to store information and pass on to MPs in future. Selectivity-at-age and retention-at-age (vectors of length maxage+1) for the projection can be set directly with Misc$V_age and Misc$R_age, and discard mortality-at-age with Misc$Fdisc. These replace the selectivity and retention parameters in the other slots. The discard ratio is applied to Misc$R_age, and the discard mortality of the operating model is used if Misc$Fdisc is not provided. The at-length curves used to generate length composition data are not updated.
