I can't stand the ammonia flavor of Chondrichthyes, plus the bioaccumulation of heavy metals, mercury, ciguatoxins, the toxic amounts of vitamin A in liver...

There are many excellent seafood but this is dog-food grade at best, not decent food for humans unless you haven't anything else. Cooking with urine would be healthier providing the same flavor without the extra-poisons. Pretty disgusting stuff.

... which doesn't taste nearly as bad as you've heard and is produced in limited quantities only as result of the few bycatch sharks accidentally netted each year.
