Abstract
  This report updates the Mid-East Coast orange roughy stock assessment for 2022. The fishery, observational data from trawl surveys, acoustic surveys, and age and length composition data, and the assessment model structure and assumptions are described. The stock was estimated to be below the depletion target range but slowly rebuilding. A hypothesis of skipped spawning was used to explain a high estimated age of first spawning. The assessment was accepted for providing scientific advice.
