Line Fishing

Longline, which is more commonly referred to as line fishing, is a technique used mainly for commercial fishing. It is, simply put, a method which uses a long line with a selection of baited hooks and various branch lines. The branch lines are called snoods and are shorter than the main lines, and are usually attached using individual clips. Lines are set at various points in the water, depending on the species being fished, sometimes at the surface, sometimes more towards the bottom. The number of snoods and lines depends on the type of fish, the particular industry and several other factors. Some boats are 25 lines and some, larger commercial vessels have 2500 lines, each baited by hand. The ships used for longline fishing are specially equipped for this type of fishing, with unique setups and holders for the line, and proper holding and storage equipment for the large species which are typically sought on longline fishing excursions. These boats are creatively named longliners.

Swordfish, tuna and halibut are some of the fish which are commonly caught using longline fishing methods. Tuna and swordfish are examples of fish that can be caught closer to the surface, and halibut or cod can be found closer to the floor of the sea.

This type of fishing is not always widely accepted, because, as one can assume, though there are certain species or a particular species that is being sought, there are others that may be caught by accident. Sometimes these species are young, endangered or at risk, and consequently, this type of fishing can pose a threat to a specific species overall health and wellbeing.

Further, this type of fishing does not make it easy to catch and release, and therefore many fish can be killed accidentally. Albatross is an excellent example of a bird species which has been harmed by this type of fishing. Further, it isn’t even just fish that are subject to the residual damage of longline fisheries, it is also birds, turtles and sharks as well.

As awareness increases surrounding the risk and the negative consequences of this type of fishing, the industry is trying to reduce these negative consequences. Some of how this is being done include:

  • Reducing time between setting and checking lines; this helps make sure that the lines are not left to catch accidental species and reduces the impact of ‘bycatching.’
  • Better equipment; using less live bait, better, more humane hooks and other more refined equipment can help reduce these negative impacts.
  • Fishing in colder weather; warmer weather reduces the stress of fish, making many species, including those not being sought, more susceptible to being caught and more easily killed.
