Harvest-class: Class "Harvest"

Description

The component of the operating model that controls harvest.

Slots

Name

Character. Identifying name

type_PT

Character. Whether to manage preterminal fishery catch from exploitation rate ("u") or catch target ("catch"). Default is "u",

type_T

Character. Whether to manage terminal fishery catch from exploitation rate ("u") or catch target ("catch"). Default is "u",

u_preterminal

Numeric. If type_PT = "u", the exploitation rate of the immature stock in the pre-terminal fishery. This will be converted to an instantaneous fishing mortality rate, i.e., F_preterminal = -log(1 - u_preterminal).

u_terminal

Numeric. If type_T = "u", The exploitation rate of the return in the terminal fishery. This will be converted to an instantaneous fishing mortality rate, i.e., F_terminal = -log(1 - u_terminal).

K_PT

Numeric. If type_PT = "catch", the catch target of the immature stock in the pre-terminal fishery.

K_T

Numeric. If type_T = "catch", the catch target of the return in the terminal fishery.

MSF_PT

Logical. Whether to implement mark-selective fishing in the preterminal fishery, with no retention on unmarked fish.

MSF_T

Logical. Whether to implement mark-selective fishing in the terminal fishery, with no retention on unmarked fish.

release_mort

Vector length 2. The proportion of released fish that die after release, in the pre-terminal and terminal fishery. Implemented to model mark-selective fishing. Not used if either MSF_PT or MSF_T is FALSE.

vulPT

Vector length maxage or matrix [nsim, maxage]. Vulnerability schedule (between 0-1) in the preterminal fishery. Values indicate the proportion of fishing mortality experienced by each age class, where F_preterminal = -log(1 - u_preterminal).

vulT

Vector length maxage or matrix [nsim, maxage]. Vulnerability schedule (between 0-1) in the terminal fishery. Values indicate the proportion of fishing mortality experienced by each age class, where F_terminal = -log(1 - u_terminal).
