Commercial fishing is terrible not only for the environment but leaves a large amount of trash in the ocean. It creates a ton of micro plastics and fucks up entire biomes.

if you ever watch a documentary of the great pacific garbage patch it usually shows the most rampant and dangerous items from aquatic life tends to be discarded fishing nets. They all suck though, just nets suck more and get cut off all the time.

Commercial fishing is probably the biggest contributor to ocean plastic pollution.

Much like commercial industry is the biggest contributor to atmospheric pollution.

You know, I think I'm beginning to see a trend here.

Fishing industry is evil and sucks big times. They just dump their gear (e.g. nets and longlines) in the open water and it's a bane for turtles, sharks, whales, sea birds, seals etc. It's not an accident. The gear seems to be deliberately dumped as the expensive stuff is removed. Read this article if you want to know why they do it. In addition those trawler/fish factory vessels are often part of ghost fleets where 75% of them kill every living being within a miles long radius for weeks on end without any controlling instance.

If you're now under the assumption that it would be better to buy fish from fish farms. It also sucks tremendously. At least when farmed in open pen sea cages out of multiple reasons:

• Pesticides and Antibiotics are released into the sea
• Viruses and parasites escape into the sea
• Salmons escape and alter natural biodiversity
• Excess food and waste lead to oxygen deprivation in the surrounding waters (dead zones)

In addition (and I don't know why WWF isn't calling it out): Whales are essentially hunted because of farmed fish. That's my own conclusion. They don't openly admit it but because whales need tons of krill they are a direct competition to the omega-3 supplement market and feed for salmon farms. The culprits are Norway (they are real eco terrorists if you look behind their green facade at home), Ruzzia, Japan & Scottland. Not only whales but also penguins and seals depend on krill. And those animals are already suffering from H5N1 (with animal agriculture being the culprit again).

What the greedy bastards don't get is, when they kill off the whales, they kill off the krill too. As so often humans disturb eco systems developed over millions of years. In this case it's the poop loop.

The intention of my wall of text is to move the people who have a modicum of interest left to save the oceans to consider to ditch any fish caught in the oceans or bred on salmon farms (btw they are feeding them chicken bones too). Humans need Omega 3 DHA & EPA fatty acids. You can easily get those via algae capsules. That's where fish get theirs from essentially.

Only we the consumers have the power to break the vicious circle but we're to uneducated and complacent. As long as there's a market they'll ruthlessly plunder the ecosystems till nothing is left. Some say we're already nearing that moment with parts of the oceans.
