Update of main indicators of the stock status of Greenland halibut in the Gulf of St. Lawrence (4rst) in 2015 / : Science response

20 Jan 2016

LAWRENCE (4RST) IN 2015 Context The stock assessment of Greenland Halibut (Reinhardtius hippoglossoides) in the Gulf of St. [...] In interim years, a summary review of the resource's main indicators is made in order to determine whether major changes in the stock status would warrant more in-depth study prior to the planned assessment in the winter of 2017. [...] Stock Status Indicators The biomass index from the 2015 DFO survey was slightly above the historical average and comparable to the value observed in 2014 (Figure 3). [...] The abundance of one-year-old fish (0–20 cm) remained high in 2015 in the DFO survey (Figure 4), and the abundance of two-year-old fish (20–30 cm) increased to its highest value in the historical series. [...] Conclusions Since 2014, the performance of the fishery has been very different in the western Gulf compared to the area north of Anticosti and Esquiman.
