Salmon

Salmon are common passive mobs found in oceans and rivers.

Spawning
Salmon spawn underwater at 12-32 blocks away from the player.

Java Edition
Salmon spawn in groups of 3–5 in cold or frozen oceans, as well as their deep variants. They also spawn in rivers and frozen rivers.

Bedrock and Legacy Console Edition
Salmon spawn in groups of 3-5 in lukewarm, cold, normal, frozen oceans, their deep variants and rivers. Salmon spawn in small, normal, and large sizes $$.

Drops
When killed, salmon drop:
 * 1 (1  if killed while on fire)
 * 1 (5% chance)
 * 1 s (25% chance) if salmon size is small or medium.
 * 1-2 s (25% chance) if salmon size is large.
 * 1-2 orbs when killed by a player or tamed wolf.

Behavior
Salmon tend to swim in schools of fish (a maximum of six salmon per school). Salmon are able to swim up approximately 4-5 blocks in waterfalls.

The player may collect salmon by a water bucket on it, which gives the player a bucket of salmon. Salmon placed with buckets will not despawn naturally. When that fish bucket is against a block, it empties the bucket, placing water with that fish swimming in it. An empty bucket may be used as well.

Weaknesses
Salmon are unable to survive out of water. Outside of water, they flop around for a while until eventually they start to suffocate and die. Salmon will flip around on their sides. In Bedrock Edition and Legacy Console Edition, they will rotate when flipping. Salmon also cannot swim or breathe in cauldron water.

Salmon have a weakness to weapons that have the Impaling enchantment, which also affects other fish and water/ocean mobs.

Entity data
Salmon have entity data associated with them that contain various properties of the mob.
