Well it depends on the type of fish you are talking about.
eyeballs,bones,scales,and head, but you cannot eat the gills for sure
the gross part
head scales tail eyes entrails bones fins (some) skin
Guts, fins, tail and eyes.
lungs,
dont eat fish
depends on the fish, but i wouldn't recomend bones! :D
All parts of some fish are eaten by different people. However, it is typical in Western cultures not to eat the head, skin, spine/bones, and fins.
they dont eat they are dead
certainly not the skeleton because you could choke on all those bones.
No they dont
they dont eat other fish they just attack them to kill
dont you mean saltwater fish?
