Figure 7. A comparison of porbeagle survey abundance in 2007 and in 2009. Circles indicate porbeagle catch where crosses indicate nulls. Catch abundance per survey station is represented by a graduated symbology, whereas average temperature at the depth of the gear is represented by a colour ramp. Figure 8. Porbeagle landings in northwest Atlantic (NAFO 2-6) from 1961 to 2011.
