This is a single-sex model with 11 age classes, the catch data starting in 1979 and ending in 2002. The model was fitted to two data components: survey abundance index and commercial catch at age.
x.sbw
scape
containing:
N |
predicted numbers at age |
B |
predicted biomass, recruitment, and observed landings (year things) |
Sel |
predicted selectivity and observed maturity (age things) |
Dev |
predicted recruitment deviates from the stock-recruitment curve |
Survey |
survey abundance index and fit |
CAc |
commercial C@A (catch at age) and fit |
The survey abundance index was preprocessed so that it contains only age 4 and older.
Estimated parameters: R0, Rinit, Rplus, Sleft[commercial], Sfull[c], q, and 33 recruitment deviates.
