CSRA: Catch at size reduction analysis

Description Usage Arguments Author(s)

View source: R/Misc_Exported.R

Description

What depletion level and corresponding equlibrium F arise from data regarding mean length of current catches, natural mortality rate, steepness of the stock recruitment curve, maximum length, maximum growth rate, age at maturity, age based vulnerability, maturity at age, maximum age and number of historical years of fishing.

Arguments

M

A vector of natural mortality rate estimates

h

A vector of sampled steepness (Beverton-Holt stock recruitment)

Linf

A vector of maximum length (von Bertalanffy growth)

K

A vector of maximum growth rate (von Bertalanffy growth)

t0

A vector of theoretical age at length zero (von Bertalanffy growth)

AM

A vector of age at maturity

a

Length-weight conversion parameter a (W=aL^b)

b

Length-weight conversion parameter b (W=aL^b)

vuln

A matrix nsim x nage of the vulnerabilty at age (max 1) to fishing.

mat

A matrix nsim x nage of the maturity at age (max 1)

ML

A vector of current mean length estimates

CAL

CAA

A catch-at-age matrix nyears x maximum age

maxage

Maximum age

nyears

Number of historical years of fishing
