Sharks and squid  keep their urine in their circulory systems to prevent
natural osmosis from desicating them in the ocean. Fish have other
mechanisms, and fresh water fish have reversre mechanisms. Usual way to
prepare shark it to soak in milk to remove the urea and uric acids, much of
which are ammonia.

And never a rider that cain't be throwed.

: As for the ammonia issue, I read several years ago about a Japanese
: whaler (I think it was, anyway) that hauled aboard one of those
: deepwater giant squids, and the crew cheerfully set about preparing the
: World's Largest Order of Sashimi. They found out, the hard way,
: something that marine biologist seem not to have discovered hitherto,
: which is that deepsea squid process their ammonia excretions
: differently, under high water pressure, from their smaller
: surface-dwelling relatives. Apparently after a deep sniff, the cooks
: decided it would be a good idea to salt and scour the flesh, and then
: rinse it, to remove the slight trace of ammonia from the surface. (It
: had been alive when hauled up, or close to it, presumably dying of the
: bends or some such.) Anyway, they removed all the surface ammonia to
: discover that when they took the first bites, there was plenty more
: ammonmia where that came from, right in the flesh of the squid.
