TAS ’18 Stephen Kade created this infographic to depict a longline fishing survey.

Longline fishing is a technique that consists of one main fishing line with many baited hooks that come of that line on shorter lines, (like branches off a tree) attached at various distances. Long lines are used in both coastal areas and the open ocean and are often placed to target specific species. If the long line is suspended in the top or mid depth water, it is called pelagic longline fishing. If it is on or near the ocean floor by weighting it down to the sea floor, it is called bottom longline fishing. A high-flyer buoy is placed at either end to mark the position of the line in the water so boats can see it while submerged, and so it can be found when it needs to be retrieved. Weights are placed on each end and the middle of the line to hold the line down to a specified depth.Read the blog post
