Fish has been a source of white meat for many years. The demand for fish products has driven fishers to devise techniques to fish to maximize their catches. Regulations have been drafted and implemented to curb rouge fishing and to safeguard endangered species from being harvested (Anuja, Yadav, Krishnan & Kumar, 2019). This essay will address the challenges of using a hook-and-line fishing technique.
A line-and-hook comprises a hook at the end of the line. The hook must be either J-shaped or a circle hook, and barbed or not. The system can be used in different setups such as:
- Trolling lines: they are barbed hooks dragged by vessels in shallow waters or deep seas depending on the target species (Anuja et al, 2019).
- Long line: they are hooks suspended from a stationary vessel spreading across great lengths (Starr et al, 2016).
- Jigger lines: they are hooks suspended on a path that is moved vertically. The primary use of such a system is to catch squids and cod fisheries.
- Pole and line gear: this is the most commonly used small scale fishing tool (Starr et al, 2016).
Starr et al.(2016) states that this fishing method affects the fish population if mass harvesting is undertaken. It also poses a danger in the collection of certain species that are endangered or are not edible. It may cause an area to be wiped off a certain species if control measure is not put in place to curb overfishing in the area .After massive fish harvesting, the area should be left for nature to take its toll and for them to reproduce and grow again in population.
- The technique does not affect sea bottom life since they are suspended in the waters (Starr et al, 2016).
- The hook type used spares the fate of non-targeted species, i.e. a circle hook can be removed without affecting the fish baited (Anuja et al, 2019).
- There is time wastage if the fish levels are low.
- Birds that prey on kinds of seafood may end up victims of being baited and drowned if the baits and baited fish are near the surface of the sea (Anuja et al, 2019).
Hook-and-line fishing techniques have evolved over the years. It has proven to be an eco-friendly fishing technique since the process is not repeated at the same spot and fishing points are changed constantly. The species that are hooked can survive if they were not part of the intended target group. All that matters to safeguard endangered and non-targeted species is a circle hook. Fishing shall remain a useful and essential source of white meat for ages to come.
