Assessment of the Quebec North Shore (4S) herring stocks in 2016

Chairperson: Charley Cyr

Context

Since 1992, the Quebec North Shore (NAFO Division 4S) herring stocks are managed using a preventive Total Allowable Catch (TAC) of 4,000 t due to the lack of scientific information to establish a formal TAC. The TAC is totally allocated to the different fishing fleets and to all catches, irrespective of the spawning stock. Between 1984 and 2010, herring landings averaged 476 t per year. Since 2011, catches have significantly increased, reaching or exceeding the TAC.

A first series of acoustic surveys was conducted in 2009, 2010, 2011 and 2013 on the Lower North Shore of Quebec (unit area 4Sw). A second series of surveys covering the whole 4S zone was initiated in 2016. When this series will be long enough, it will allow the use of an analytical assessment of the two spawning groups of the Quebec North Shore herring stocks and the establishment of limit reference points that would make it possible to develop a strategic framework for fisheries consistent with the precautionary approach.

The last assessment of the two herring spawning stocks in 4S dates back to 2011. An update of the stock status was produced in 2015. The Fisheries and Aquaculture Management Branch has requested a scientific advice on these stocks for the 2017 and 2018 fishing seasons.

Objectives

Provide a scientific advice of the spring and fall spawning herring stocks in NAFO Division 4S (Quebec North Shore) for the 2017 and 2018 fishing seasons. This advice shall include:

• An evaluation of the status of the herring stocks, based on:
• commercial fishery statistics following the 2015 and 2016 seasons (overall distribution of landings, breakdown by unit area, month and fishing gear);
• an update of the main biological indicators (age structure, maturity, condition, etc...) from sampling commercial data;
• sentinel catches and index of dispersion calculated from the Teleost catches;
• results of the 4Sw unit area acoustic surveys in 2009, 2010, 2011, 2013 and the whole 4S zone in 2016.
• The determination of the process to provide advice during the interim years, including a description of conditions that may warrant a full stock assessment earlier than originally planned;
• The identification and prioritization of research projects to be considered for the future.
• Perspectives and/or recommendations for 2017 and 2018 based on available data.
