Stock assessment data and model fit for ling (Genypterus blacodes) in New Zealand waters, using a Coleraine statistical catch-at-age model.
This is a two-sex model with 30 age classes and 29 length classes, the catch data starting in 1973 and ending in 2000. The model was fitted to five data components: longline abundance index, survey abundance index, survey catch at age, longline catch at length, and trawl catch at length.

||predicted numbers at age|
||predicted biomass, recruitment, and observed landings (year things)|
||predicted selectivity and observed maturity (age things)|
||predicted recruitment deviates from the stock-recruitment curve|
||commercial abundance index and fit|
||survey abundance index and fit|
||survey [email protected] (catch at age) and fit|
