Arguments

param

a numeric value representing log(R0)

numeric value, recent fishign mortality rate (apical F)

Chist

a vector of historical catch observations [nyears]

M_a

numeric value, natural mortality rate

Mat_age_a

a vector of maturity at age [nage]

Wt_age_a

a vector of weight at age [nage]
