A type of fishing gear in which short lines carrying hooks are attached to a longer main line at regular intervals. The main lines can be as long as 80 miles and have several thousand hooks. Longlines can target bottom-dwellers or top/mid-ocean dwellers.
In telephone systems nomenclature a long line is a transmission line in a long-distance communications network such as carrier systems, microwave radio links, geosynchronous satellite links, underground cables, aerial cables and open wire, and submarine cables.
a fishing line usually made of monofilament
Fishing tackle involving a horizontal line fit with hooks and held by floats.
culture The process of culturing shellfish in deep-water by hanging culture apparatus (shell-ropes, tubes, nets, etc.) from a horizontal rope suspended in the water by floats.
A type of fishing gear used to catch fish on the ocean bottom or in the water column. A typical longline includes a long fishing line with baited hooks dangling every few feet.
A longline consists of many short lines, each baited with a hook, suspended vertically from a main line that is dragged horizontally through the water. Longlines can carry thousands of hooks and stretch as long as 40 miles. This method is generally associated with moderate to high bycatch, depending on how many hooks and where and when the lines are set. Longlines set for tunas, for instance, also catch swordfish, sharks, turtles, and seabirds (the latter are attracted to the baited hooks as they are put in the water). Longlining can also be perilous to fishers as they haul in/ put out the line.
A fishing gear in which short lines carrying hooks are attached to a longer main line at regular intervals. Pelagic longlines are suspended horizontally at a predetermined depth with the help of surface floats. Demersal longlines are set at the seabed with weights.
