What is the environmental impact of commercial fishing?

The fishing industry affects a number of marine conservation issues, including: fish populations, water pollution, and habitat degradation. Some researchers have claimed that the size of the fishing industry needs to be significantly decreased in order to maintain healthy marine environments around the world.

What are the environmental impacts of fishing?

Environmental Effects

In addition to harvesting large amounts of fish and seafood to sell, large-scale fishing operations catch and often unintentionally kill untargeted marine life, including juvenile fish, corals and other bottom-feeding organisms, sharks, whales, sea turtles, and birds.

How much does commercial fishing contribute to pollution?

Plastic pollution plagues every corner of the ocean and despite growing awareness, the problem is only getting worse. Fishing gear accounts for roughly 10% of that debris: between 500,000 to 1 million tons of fishing gear are discarded or lost in the ocean every year.

What are the impacts of commercial fishing?

Aside from deliberately catching vast numbers of fish and engaging in practices like trawling which cause damage to ocean habitats, commercial fishing accounts for vast quantities of bycatch – where non-target species of marine animals are accidentally (or sometimes intentionally) caught, then tossed dead or dying back …

Why does fishing hurt the environment?

Some aspects of fisheries can have significant and long-lasting effects, e.g. destructive fishing techniques using dynamite or cyanides or inadequate fishing practices (e.g. trawling in the wrong habitat); pollution from fish processing plants; use of ozone-depleting refrigerants; dumping at sea of plastic debris that …

Does commercial fishing contribute to climate change?

Although there is a decline of fisheries due to climate change, a related cause for this decrease is due to over-fishing. Over-fishing exacerbates the effects of climate change by creating conditions that make a fishing population more sensitive to environmental changes.

Is fishing good for the environment?

Anglers play an important role in protecting and conserving the aquatic environment. They act as custodians of the waters they fish and are often the first to notice and report pollution incidents or other environmental issues that need addressing.
