The LTMS requires ICES to provide both an update in-year TAC advice for 2022 and an initial TAC advice for the first two quarters of 2023. A length-based Stock Synthesis (SS3) statistical framework was used to assess the status of the stock based on updated input data (commercial catches for 2021 and survey catches from Janu-ary 2022).
