Why Fishing Is Bad for the Environment

Some people might think that fishing is a harmless sport with no negative impacts on the environment. What you may not know, however, is that, when it comes to the environment, fishing can be a terrible thing.

In this blog post, we will explore some of the reasons why fishing is bad for the environment and some of the commonly asked questions about fishing and the environment.

Reasons Why Fishing Is Bad For the Environment


1.   Causes Habitat Destruction

Some fishing techniques can be destructive to habitats. Blast fishing and cyanide fishing are illegal in many places, and they harm surrounding habitats because they result in the removal of certain types of species that live on coral reefs.

Blast fishing refers to using explosives for catching marine animals. In contrast, cyanide fishing refers to placing a toxin near an area where corals grow, affecting nearby creatures, including fishes swimming around.

2.   Ecological Disruption

Fishing can result in the over-exploitation of marine ecosystem services.

Fishing causes adverse physiological and psychological effects on fish populations and impacts their environments by increasing stress levels and other challenges that lead to hysteresis within ecosystems.


3.   Bycatch

The number one reason you should care about bycatch is that it’s terrible for the environment and your catch.

There have been many cases where discards – unwanted fish – were found in fisherman’s collections, and this has caused concern because these by-catches often outweigh what one is looking for.

4.   Marine Debris

We all know that plastics are harmful to the environment, but did you realize how they affect marine life? Fishing debris such as buoys and lines can be just as dangerous.

In many water bodies fishing nets alone account for 46% of large plastic pieces found on shorelines.

Marine life interacts with these items in two ways – either through entanglement or ingestion- both of which cause serious health problems over time.


5.   Dilapidated Fishing Gears

Ghost fishing is when lost or forgotten fishing gear continues to catch animals.

This can be particularly wasteful and destructive because the dilapidated fishing gear will catch tons of different types that aren’t being harvested, like birds who dive for food in water bodies filled with these pesky fishing gears.

6.   Overfishing

The problem with overfishing is not just a single fish; it can have repercussions for the entire ecosystem. Harms from industrial fishing have been felt for years in the form of reduced population sizes and species extinction.

One example may be seen in Atlantic cod, where they were nearly driven to extinction by humans due to their popularity as an ingredient used in many foods.

An apparent downside of industrial fishing practices such as nets dragging along bottom sediments causes damage like tearing up rocks or ripping up seabed grasses.

Frequently Asked Questions on Fishing Effects to the Ecosystem

Why Is Fishing So Bad for the Environment?

Fishing can be disruptive to the ecosystem, primarily if it targets species that consumer’s desire. For example, fishing for salmon and tuna has declined these fish populations.
Overfishing also affects how much carbon storage area is available, contributing more towards climate change.

Are Fishing Nets Bad for the Environment?

Fishing nets cast into the ocean can result in marine life being trapped and killed. According to a report jointly produced by FAO and UNEP, these abandoned items remain at sea for centuries before fishermen, or other passersby discover them.

The net can result in the accidental capture of dolphins, turtles, and other marine animals.

The mesh nets are harmful to aquatic life and dangerous to humans who may come into contact with them during fishing or rowing activities.

Which Fishing Method Is the Most Harmful to the Environment?

Blast fishing is one of the most dangerous and destructive methods fishermen use. The explosions cause indiscriminate damage, which will kill many fish in an area and destroy their habitats. 

How Is Fishing Good for the Environment?

Fishing using selective fishing methods helps to adapt to the marine environment and thus avoid accidental catches – a win for both our oceans’ wildlife and fishermen who want nothing more than sustainable practices in place.

Fishing also maintains biodiversity.

In conclusion, fishing can be a great activity to do with friends and family. However, it is essential that we keep in mind the harmful effects of fishing on the environment.

We hope this blog post has taught you about the reasons why fishing is bad for the environment.
