Abstract

This document has selected some spatial plots of survey and industry catch rates and catches to assist an understanding of the Greenland halibut distribution. Figure 1 shows the location of most of the Canadian catch of Greenland halibut in 2006 and 2007 (Brodie et al., 2008), while Figure 2 plots the distribution of Greenland halibut from Canadian fall surveys for these two years (Healey, 2008). Catch per haul distribution for the 2007 summer survey on Flemish Cap is shown in Figure 3 (Vázquez and González-Troncoso, 2008). Figure 4 plots the Spanish Scientific Observers Program data CPUE for 2001 to 2006 (GonzálezTroncoso, Sacau and González-Costas, 2007). Figures 5 and 6 show the distribution of catches based on the Spanish Scientific Observers Program data and Spanish survey data respectively (GonzálesCostas, pers. commn).
