Is this unusual? I thought wild-caught fish often (usually?) had parasitic worms in it, and that they were generally not dangerous to humans, at least as long as the fish was cooked. There's a video I saw, which I don't suggest looking up, in which a chef explains that he knows the fish is fresh if the worms are still moving.

Usually farmed fish, or wild fish caught near fish farms, are the ones riddled with parasites.

Pretty sure parasites are widely present among wild fish. Not defending fish farms, but parasites aren't only present on fish farms

aren't only present on fish farms

No. But if you keep a lot of fish really tightly packed in the same place those parasites will have a much easier time spreading.

[–] protist@mander.xyz 6 points 5 months ago (1 children)

Yes. Again, my point is that fish parasites are widely present in wild fish populations and have been since before fish farming existed

[–] tb_@lemmy.world 4 points 5 months ago

Yes... But with open net fish farming you get more fish with parasites and more parasites per fish. So it was a lesser problem before.

Open net fish farms are proven to increase parasite counts on nearby wild stock

[–] protist@mander.xyz 14 points 5 months ago

Sure, but parasites are still widely present in wild populations

[–] Chozo@fedia.io 2 points 5 months ago* (last edited 5 months ago) (1 children)

Pretty sure that's a selection bias, since most fish that are eaten - or would otherwise be examined for parasites - are farm-raised fish.

No, that's the Canadian Department of Fisheries and Oceans official study:

  1. That article neither supports nor denies your claim: it just says parasites have evolved resistance to what was previously used against them.

  2. The major issue there is with the anti parasite treatment: that is what is killing herring.

  3. Parasites do not magically appear from nowhere. They are species which have co-evolved with their hosts for millennium. These fish parasites are extremely common across the entire ocean. Farms just provide a place for large groups of fish to get infected.

All of which is to say that parasites in fish are common in wild fish which are never near farms.

[–] kbin_space_program@kbin.run -5 points 5 months ago

Then you didnt read it.

Fact is that open water fish farms devastate wild stocks.

[–] HappycamperNZ@lemmy.world 4 points 5 months ago

I suppose it depends on what type, and if they are hazardous to humans.

Worms- ok. Worms that also affect us - not OK.
