Chub mackerel stock assessment using KAFKA

    Chub mackerel stock assessment has been conducted using cohort analysis with Kalman filter (KAFKA). Calculations are provided for different scenarios with a set of biological uncertainties such as natural mortality, weight at age and maturity at age. Scenarios with the highest maturity and weight have led to higher SSB values compared to the other scenarios. Stock assessment best corresponds with SSB indices.
