Moro ami fishing is breaking the coral reefs using rocks and this makes all the fish go out of their habitat and fishermen get to catch them.
Cyanide fishing uses a mixture which is called sodium cyanide to temporarily paralyze or stun the fish
Dynamite fishing is the name itself, killing fish with dynamites.

So the answer is D.
