Why Is Bottom Trawling A Bad Fishing Technique?

Introduction

Sobat Penurut, fishing is an important industry that provides food and livelihood for millions of people around the world. However, some fishing techniques can have negative impacts on the environment and the marine ecosystem. One of these techniques is bottom trawling, which involves dragging a large net along the ocean floor to catch fish and other marine creatures. While this method may be efficient in catching large quantities of fish, it can also cause significant damage to the seabed and the habitats of many marine species. In this article, we will explore why bottom trawling is a bad fishing technique and its impact on the environment.

The Definition of Bottom Trawling

Bottom trawling is a fishing technique that involves dragging a large net along the ocean floor to catch fish and other marine creatures. This method is commonly used to catch fish that live close to the seabed, such as flatfish, cod, and haddock. The net is usually equipped with heavy weights and rollers that help it move along the seabed, and it can be up to several kilometers long.

The Negative Impact of Bottom Trawling on the Environment

Bottom trawling can have a significant impact on the environment and the marine ecosystem. Here are some of the negative effects of this fishing technique:

– Habitat destruction: Bottom trawling can cause significant damage to the seabed and the habitats of many marine species. The heavy weights and rollers on the net can crush corals, sponges, and other benthic organisms that live on the seabed, destroying their habitats and reducing their populations.- Bycatch: Bottom trawling can also result in high levels of bycatch, which refers to the unintentional capture of non-target species. Many marine creatures, including sea turtles, sharks, and dolphins, can get caught in the net and die as a result.- Disturbance of sediment: The heavy equipment used in bottom trawling can also disturb the sediment on the seabed, reducing water clarity and harming the health of benthic organisms.- Overfishing: Bottom trawling can lead to overfishing of certain species, as it can catch large quantities of fish in a short amount of time. This can lead to the depletion of fish stocks and the collapse of fisheries.

The Alternatives to Bottom Trawling

There are several alternatives to bottom trawling that can be more sustainable and environmentally-friendly:

– Pole and line fishing: This method involves using a fishing rod and line to catch fish one at a time. It is a more selective method that can reduce bycatch and minimize the impact on the environment.- Trap and pot fishing: This method involves using traps and pots to catch fish, which are then retrieved from the ocean floor. It is also a more selective method that can reduce bycatch and minimize habitat destruction.- Longline fishing: This method involves using a long line with baited hooks to catch fish. It can be more selective than bottom trawling and can reduce the impact on the environment.

Why Is Bottom Trawling A Bad Fishing Technique?

1. Habitat Destruction

Bottom trawling can cause significant damage to the seabed and the habitats of many marine species. The heavy weights and rollers on the net can crush corals, sponges, and other benthic organisms that live on the seabed, destroying their habitats and reducing their populations. This can have a cascading effect on the entire ecosystem, as many marine species depend on these habitats for food and shelter.

2. Bycatch

Bottom trawling can also result in high levels of bycatch, which refers to the unintentional capture of non-target species. Many marine creatures, including sea turtles, sharks, and dolphins, can get caught in the net and die as a result. This can have a significant impact on the populations of these species, as they may not be able to reproduce fast enough to compensate for the loss.

3. Disturbance of Sediment

The heavy equipment used in bottom trawling can also disturb the sediment on the seabed, reducing water clarity and harming the health of benthic organisms. This can have a negative impact on the entire ecosystem, as many marine species depend on clear water and healthy benthic communities for survival.

4. Overfishing

Bottom trawling can lead to overfishing of certain species, as it can catch large quantities of fish in a short amount of time. This can lead to the depletion of fish stocks and the collapse of fisheries. This can have a significant impact on the livelihoods of many people who depend on fishing for their income.

5. Unsustainability

Bottom trawling is an unsustainable fishing method that can have negative long-term effects on the environment and the marine ecosystem. It can lead to the depletion of fish stocks and the collapse of fisheries, which can have a significant impact on the food security and livelihoods of many people around the world.

6. Lack of Regulation

Bottom trawling is often poorly regulated, which can lead to overfishing and the depletion of fish stocks. Many countries do not have adequate laws and regulations to protect the marine environment and the livelihoods of local fishing communities.

7. Alternatives

There are several alternatives to bottom trawling that can be more sustainable and environmentally-friendly. Pole and line fishing, trap and pot fishing, and longline fishing are all more selective methods that can reduce bycatch and minimize the impact on the environment. These methods can also be more profitable for local fishing communities and can help to sustain fish stocks for future generations.
