Joint MoP-SC Workshop on Harvest Strategy Management Objectives (WS2023-HSMO)
The joint SIOFA MoP-SC intersessional workshop to define management objectives (WS2023-HSMO) will consist of 2 sessions that will be held from 07:30 to 11:30 UTC on Tuesday 7 and on Wednesday 8 November 2023.
The arrangements for WS-2023-HSMO are:
Orange roughy (Hoplostethus atlanticus) acoustics
The SIOFA Scientific Committee (SC) is tasked to provide management advice for three important species (orange roughy, splendid alfonsino and Patagonian toothfish) to the Meeting of parties of SIOFA. CMM 2020/15 (paragraph 5) requires out that the orange roughy (Hoplostethus atlanticus) stocks shall be assessed every three to five years. The first stock assessments of orange roughy were conducted in 2018 (Cordue 2018a, 2018b) and the second assessments were conducted in 2022 (Roa-Ureta 2022). The next stock assessment is scheduled for completion for SC10 in 2025.
Age and growth of orange roughy (Hoplostethus atlanticus)
The SIOFA Scientific Committee (SC) is tasked to provide management advice for three important species (orange roughy, splendid alfonsino and Patagonian toothfish) to the Meeting of parties of SIOFA. CMM-15 (2020) paragraph 5 requires that the orange roughy (Hoplostethus atlanticus) stocks shall be assessed every three to five years. The first stock assessments of orange roughy were conducted in 2018 (Cordue 2018a, 2018b) and the second assessments were conducted in 2022 (Roa-Ureta 2022). The next stock assessment is scheduled for completion for SC10 in 2025.
SIOFA Vulnerable marine ecosystems mapping
SIOFA Conservation and Management Measures (CMM) 2019/01 directs the Scientific Committee (SC) to provide maps of where vulnerable marine ecosystems (VMEs) are known to occur, or likely to occur, in the Agreement Area. The Meeting of the Parties shall act on the advice of the SC in regards with the VME habitat mapping and update its interim bottom fisheries measures.
Bomb radiocarbon ageing of alfonsino (Beryx splendens)
This is a pilot study to validate ageing of alfonsino using bomb radiocarbon analyses of alfonsino otoliths.
Its main objective is to provide advice to the SIOFA Scientific Committee on the validity of ageing of alfonsino (Beryx splendens) in the SIOFA Area.
Protocols to designate and evaluate MPAs in the SIOFA Area
This project will provide options for consideration by the SIOFA Scientific Committee for evaluating and monitoring protected areas in the SIOFA Area.
Overall objectives:
Objective 1: Provide advice to the SIOFA Scientific Committee on the options for evaluating and monitoring current protected areas (CMM2020/01 Annex C) in the SIOFA Area.
Objective 2: Provide advice to the SIOFA Scientific Committee on approaches to developing protocols for designating new protected areas (as per CMM2020/01 paragraph 5d) in the SIOFA Area.
