Is it okay to eat fish with an isopod parasite on it?
I bought some frozen Hairtail fish (Chinese: 帶魚) and one of them had some kind of isopod on it. I already removed the bug and threw it out, but after some research it looks a lot like the image here: https://en.wikipedia.org/wiki/Cymothoidae
Is it still okay to cook and eat the fish?
Best Answer
It should be safe to still eat the fish, especially if you're going to be cooking it! IMO parasites like the isopod that you found are far less dangerous than less visible ones such as worms, flukes etc.
Quoting from: https://en.wikipedia.org/wiki/Cymothoa_exigua
C. exigua is not believed to be harmful to humans, except it may bite if separated from its host and handled.[14]
In Puerto Rico, C. exigua was the leading subject of a lawsuit against a large supermarket chain; itis found in snappers from the Eastern Pacific, which are shipped worldwide for commercial consumption. The customer in the lawsuit claimed to have been poisoned by eating an isopod cooked inside a snapper. The case, however, was dropped on the grounds that isopods are not poisonous to humans and some are even consumed as part of a regular diet.[9]
It seems to me that a closely analogous example to the isopod you found on fish are pea crabs in shellfish: https://en.wikipedia.org/wiki/Pea_crab. Though perhaps pea crabs are less parasitic to shellfish than isopods are to fish.
There was once I was having some cooked clams at a resto. When the clams were served, I found every single one occupied by at least one pea crab. They were cooked along with the clams. I just removed and discarded the crabs, the flesh of the clams was completely fine.

Isopods are not harmful to humans, although they have dozens of sharp claws on their underside, and Chambers said they can be quite vicious and are capable of giving a nasty nip if you pick them up.Can you eat a fish with tongue-eating louse?
A tongue-eating louse is known for doing what's described as an "icky job" as it wants to get inside the mouth of an animal where it's found to "eat" and eventually, replace the tongue. As specified in an NPR report, fortunately for us humans, the isopod is not affecting us.WARNING!! TAPEWORM PARASITE SUSHI! Would You Eat This Fish?

Answer 2
I'd say no.
Conventional wisdom suggest that when in doubt, throw it.
Throw it away, go back to your fishmonger/store and tell them about that.
If that fails, do not buy from that brand (if there's any brands attached to your frozen fish)
Answer 3
Fish is such food that causes food poisoning quickly. And if you see something there, like isopods, or the colour is not okay, or it smells strange, it's better to through it away. Even if you cook it it doesn't guarantee you safety.
