Fish are aquatic life-forms that are found everywhere throughout the different types of oceans.
They are referred as mobs and are listed below.
Fish can be found swimming in rivers and oceans. All types of fish appear in oceans. Only cod and salmon appear in rivers, and they can also spawn in player-created bodies of water. Upon death, they drop the raw equivalent of their meat, with a chance to drop a bone[Bedrock Edition only] or bone meal.[Java Edition only]
