Yield in biomass per length group of NSS herring 1982-90; Effect of F on stock biomass; Sensitivity of the model to varation in k and Lmax
Supplementary file 2. Input data to SystmodII
Each year from 1982 until 2009 NSS herring stock (ICES working grop reports and Holst et al., 1996): No of individuals at age; Average weight at age; Average length at age; Standard deviation to length at age; VPA data for total Stock biomass and spawning Stock biomass;Yearly F-values. Natural mortality at age
Supplementary file 3. Output data from Systmod II
The model was run assuming observed F and historical recruitment: Simulated no of individuals per year and lengthgroup; Simulated length and biomass per year and lengthgroup, Simulated yield. A possiblity to calculate catch and resulting biomass when assuming different F-values.
