CalculateQ: Optimize for catchability (q)

Description

Function optimizes catchability (q, where F=qE) required to get to user-specified stock depletion

Usage

CalculateQ(x, StockPars, FleetPars, pyears, bounds = c(1e-05, 15), control)

Arguments

x

Integer, the simulation number

StockPars

List of Stock Parameters

FleetPars

List of Fleet Parameters

pyears

The number of years to project forward. Equal to 'nyears' for optimizing for q.

bounds

A numeric vector of length 2 with bounds for the optimizer

control

List. Control parameters including optVB=TRUE to optimize for vulnerable biomass instead of SSB?
