    Résumé

    Mackerel icefish have been harvested in the CCAMLR Region for over thirty years. In the Atlantic sector of the Southern Ocean they feed preferentially on krill and are themselves preyed upon by fur seals and several avian species. These attributes make them suitable for consideration within the CEMP. With that in mind the following indices are outlined that might be incorporated in the programme: Standing Stock, Cohort Strength and Recruitment, Natural Mortality, Length at Age 1+ and 2+ years, Condition, Gonad Maturity and Diet
