International Fisheries Stock Assessment Review Workshop


Over Monday 28 November to Friday 2 December 2016, the annual International Stock Assessment Workshop funded by the NRF and DAFF will be taking place at UCT (Mathematics Building Room M212).

This year the four scientists invited to comprise the Review Panel are Alistair Dunn (New Zealand), Malcolm Haddon (Australia), Ana Parma (Argentina) and André Punt (USA).


The primary topics to be covered are the following (some other issues may also be added for limited attention):

  1. South African hake — a review of progress on assessment models which take account of cannibalism and inter-species predation between the two species that comprise this resource; consideration of the implication of the current assessment for future hake TACs; a report on progress on the GeoPop spatio-temporal distribution model.
  2. Sardine — a review of progress on multi-stock assessment models for the South African sardine resource and their implications for management.
  3. Penguin-fishery interactions — a review of results of analyses related to monitoring results from an island closure study and of other studies related to the possible impact of pelagic fishing close to Robben and Dassen islands on their penguin populations.


Discussion is planned to take place from 9 am to 5-30 pm each day, with two 30 minute breaks for tea at 10-30 am and at 3-30 pm, and a 90 minute lunch break at 12-30 pm - except for part/all of the Thursday afternoon which will be reserved for the Panel to prepare their report. A detailed schedule indicating which topics will be discussed and their times will be circulated in due course.

For the most part, discussions will be at a fairly high technical level, however on the final day (Friday 2nd) at 3-30 pm in room M304 of the UCT Mathematics Building, the International Review Panel will provide a summary of their recommendations at a level suitable for a lay audience, and open for questions from the attending audience. Dr Kim Prochazka, Director Research of DAFF Fisheries Branch, will chair this session.

Documentation and attendance

Likely commencing Tuesday 22nd November, documents for background and for discussion at the workshop will be posted on the following website for prior download, as they become available:

Attendees are asked to bring their own copies of documents (found on the website above) to the meeting as they will not be made available in other forms. However, for technical reasons, there may be some documents which cannot be made available in this way; these will be emailed to those who advise attendance as requested below, and a limited number of hard copies will be available during the workshop.

Because of the need to maintain a workshop type interaction, Chairs will limit discussion during each session primarily to panel members and selected key contributors seated at the central table. However others are welcome to attend any of the sessions, and their interventions will be entertained in the discussions to the extent that time permits.

Inter alia for catering purposes, and for the provision of some documents as indicated above, we need to assess/document likely attendance. Could those wishing to attend part or all of the event please send an email to Di Loureiro copied to and Candysse Vrancken indicating the topics fow which you wish to attend. This is not necessary if you wish to attend the final Friday lay summary session only.
