Robson is closer to home in this final instalment, but his European fishing trip promises many exotic and varied sporting challenges. First, he is on the hunt for the classic prize of game fishing – the mighty blue marlin. The intrepid seaman’s base is Faial, an island in Portugal’s Azores group. As Robson sets out, clouds gather on the horizon. Will the weather thwart his mission? Next stop is the Canary Islands where Robson attempts to test the limits of his gut by tasting escolar – a snake mackerel found in warm waters around the world. Consumption of escolar is banned in several countries because of its ability to make the eater violently ill as rapidly as half an hour after a meal. The Canary Islanders are big fans of the delicacy. Will Robson share their enthusiasm? The final destination of the series is the River Ebro in Spain, home to the wels catfish. This freshwater monster, which can grow up to ten feet in length, can only be found in European rivers and lakes. Robson is a dab hand at reeling in a 20lb salmon. But how will he fare against one of these beauties, which can be 16 times that size?
