Class

The component of the operating model that controls marine 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. Can also be a matrix [nsim, proyears]. If type_PT = "u", the harvest rate of the immature component of the population in the pre-terminal fishery. The harvest rate is the ratio to kept AEQ catch to (kept AEQ catch + return), where AEQ are adult equivalents.
u_terminal: Numeric. Can also be a matrix [nsim, proyears]. If type_T = "u", the harvest rate (ratio of kept catch to return) of the terminal marine fishery.
K_PT: Numeric. If type_PT = "catch", the catch target of the immature component of the population 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).
