One net, two boats - pelagic pair team fishing for mackerel of the French coast at Croisic. Back in the 1970s, in colder UK waters small inshore vessels found they lacked sufficient power to catch mackerel using trawls - given that mackerel are the cheetahs of the ocean! Instead, a huge fleet of handline fishermen developed up to the early 1980s when the shoals of mackerel moved to the west of Ireland and further north to the west coast of Scotland.
