Stock assessment data and model fit for saithe (Pollachius virens) in Icelandic waters, using an ADCAM-type (separable) catch-at-age model.
This is a single-sex model with 14 age classes, the catch data starting in 1980 and ending in 2014. The model was fitted to two data components: survey abundance index and commercial catch at age.
List of class
||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|
||survey abundance index and fit|
||commercial [email protected] (catch at age) and fit|
||survey [email protected] and fit|
Bjornsson and Magnusson (2009) give a general description of the ADCAM modelling platform. The specific model used in this assessment is described in the ICES (2015) assessment report.
Fleet selectivity is modelled with three periods: 1980-1996, 1997-2003, and 2004 onwards.
