How Manufacturers Drown Fish by Adding, Not Subtracting, Electricity

The use of electricity in the fishing industry has become increasingly prevalent in recent years, but not all applications of electricity in fishing are beneficial for the environment and the fish themselves. In fact, some techniques used by manufacturers to capture fish are causing harm and even leading to fish fatalities.

The Dangers of Electrotrawling

One such technique that is causing harm to marine life is electro-trawling. This method involves dragging an electrical current through the water to stun and capture fish. While it may seem like a quick and easy way to catch a large amount of fish, the truth is that electro-trawling can have disastrous consequences for the environment and fish populations.

One issue with electro-trawling is that it can lead to the capture of non-target species. This means that other animals that live in the same area as the fish being targeted, such as dolphins, sea turtles, and seabirds, can also be affected by the electrical current and may be injured or killed as a result.

Additionally, electro-trawling can cause physical damage to fish populations. The electrical current can cause burns and wounds on the skin of fish, making it difficult for them to swim and forage for food. Over time, this physical damage can lead to a decline in the overall health of the fish population, as well as a reduction in the number of fish that are able to successfully reproduce and maintain the population.

The Alternative: Sustainable Fishing Practices

Fortunately, there are alternative fishing methods that are more sustainable and better for the environment. For example, traditional fishing methods, such as hook and line fishing, do not rely on electricity and do not pose the same risks to marine life. These methods allow fishermen to target specific species of fish and avoid capturing non-target species, reducing the overall impact on the environment.

Another option is the use of selective fishing gear, such as nets with smaller mesh sizes. This type of gear is designed to capture only the target species of fish and reduce the impact on non-target species and the overall ecosystem.

The Benefits of Sustainable Fishing

Sustainable fishing practices not only benefit the environment but also provide numerous benefits for the fishing industry and for consumers. For example, fishing using sustainable methods can help to maintain healthy fish populations and preserve the biodiversity of the ocean. This not only ensures that there will be a steady supply of fish for future generations, but it also provides a more stable and reliable source of income for fishing communities.

In addition, sustainable fishing practices can lead to improved product quality and safety for consumers. Fish that are caught using sustainable methods are often healthier and of higher quality than those caught using harmful techniques like electro-trawling. This leads to a better product for consumers and a stronger reputation for the fishing industry.


In conclusion, the use of electricity in fishing may seem like a convenient solution, but the truth is that it can have serious negative consequences for the environment and fish populations. By transitioning to sustainable fishing practices, such as traditional fishing methods or the use of selective fishing gear, we can help to protect the health of our oceans and ensure a stable source of fish for future generations.
