    Abstract

    A stratified bootstrap of icefish catch density based on the UK 2019 demersal fish survey catch rate data indicated a biomass of 53,124 tonnes (lower one sided 5th percentile: 32,399 tonnes) within Statistical Subarea 48.3. Projections for the 2019/20 and 2020/21 seasons applying the CCAMLR harvest control rule lead to catch limits (TAC) of 3,225 tonnes for 2019/20 and 2,132 tonnes for 2020/21.
