Bottom Vertical Longline Fishing

Abstract

The Bottom Vertical Longline setting the main line close to the bottom and connecting it to branch lines that extend further to several hook lines, these branch lines have an appearance similar to vertical lines. The mainline is suspended at some distance above the bottom, depending on the length of the branch line. Thus the mainline does not touch the bottom whereas the branch lines do. If some obstacle at the bottom catches the branch line, only that particular line get damaged or lost without a risk to the rest of the gear. In this type of gear, hooks are places between the sea bottom and the mainline so that the fish, which dwell near or at the bottom, are caught.
