Assessment of the Gulf of St. Lawrence (4RST) Atlantic halibut

Regional Peer Review - Quebec Region

February 17, 2015
Mont-Joli, Quebec

Chairperson: Bernard Sainte-Marie

Context

The directed Atlantic halibut fishery is practiced on a competitive basis and is carried out by longliners. To protect the population’s reproductive potential, this fishery is subject to several management measures including the control of catches by a total allowable catches (TAC). Atlantic halibut represent a by-catch for other fleets, in particular the gillnet Greenland halibut fleet.
At the request of the fisheries management Branch, resource assessment is done every two years. The purpose of the review is to determine whether changes have occurred in the status of the resource that would justify adjustments to the management plan based on the retained conservation approach.

Objectives

Provide scientific advice on Atlantic halibut stock status in NAFO Divisions 4RST. This advice shall include:

• Description of the biology of Atlantic halibut and its distribution;
• A summary of oceanographic conditions in the Gulf;
• Analysis of the commercial fishing data including landings, fishing effort, catch per unit effort, biological data;
• Analysis of data from the DFO annual research trawl survey in August and sentinel fisheries;
• Identification of monitoring indicators of the stock status during the interim years;
• Perspectives for 2015 and 2016 based on available indicators;
• Based on the assessment needs, setting research priorities for the next 5 to 10 years.
