Von Bertalanffy theoretical asymptotic length (cm)
Population standard deviation of asymptotic length (cm)
Instantaneous natural mortality rate (yr-1)
TRUE / FALSE specifying whether natural mortality is a function of individual length following Lorenzen (Lorenzen, 2000; Lorenzen, 2005)
Apical (fully selected) instantaneous fishing mortality rate (yr-1)
Minimum length at 50% fishery selectivity (cm)
Slope of the ascending region of selectivity at length (cm), see details
Maximum length at 50% fishery selectivity (cm)
Slope of the descending region of selectivity at length (cm), see details
Von Bertalanffy length at age 0 (cm)
Population standard deviation of length at age 0 (cm)
Von Bertalanffy growth coefficient
Population standard deviation of Von Bertalanffy growth coefficient
Maximum longevity (years)
An arbitrary age selected to represent “old” fish (years)
The number of age 0 fish in each simulated cohort, typical value =100,000
