The proportion of vessels for which interviews were obtained or not obtained.
Map of the Northern Irish ports, plus Greencastle, showing the proportion of vessels for which interviews were obtain for against those for which they were not. The size of the symbol for each port represents the number of commercially active, Northern Ireland fishing vessels registered there.

Comparision of the number of registered active Northern Ireland fishing vessels and the number with interviews, by size class.

Comparision of the number of registered active Northern Ireland fishing vessels and the number with interviews, by gear type.
Figure 8.
Map of the spatial access priorities of the Northern Irish fishing fleet.
Map of the spatial access priorities of the Northern Irish fishing fleet generated from data obtained from 103 interviews with skippers and boat owners in 2012. It shows the main areas used by the fleet. There are a number vessels that have a much greater range than this. All areas were included in mapping process; however, for the purpose of maintaining an appropriate scale for visual display, they have not been shown.
Figure 9.
Maps of the spatial access priorities of the four main fisheries within the Northern Irish fishing fleet.
Maps of the spatial access priorities of the four main fisheries within the Northern Irish fishing fleet: A) Nephrops, B) Pot fishing, C) Scallops and D) White fish. Maps were generated using data obtained from interviews with a total of 103 Skippers and boat owners in 2012. They show the main areas used by the fleet. There are a small minority of Nephrops vessels that have a greater range than this. All areas were included in mapping process; however, for the purpose of maintaining an appropriate scale for visual display, they have not been shown.
Figure 10.
Spatial overlap of fishers’ access priority areas within a given gear-length-port combination.
Map of the access priority areas chosen by nine Nephrops fishers, from Northern Ireland. The nine fishers’ vessels were within a given port-length combination and the map shows the spatial overlap in their responses.

Spatial access priority map and VMS effort maps for the over 15 m Nephrops fleet.
The spatial access priority map (2012) and the VMS effort maps (2009 and 2010) for over 15 m Nephrops fleet. VMS maps supplied by Laurence Rooney at AFBI. Processed VMS data were not available for all areas delineated by the fishers so this figure compares only main fishing areas where it was.
