Fishing bait

Minecraft is a game that is semi-realistic so why not add some fish baits to the game and introduce 6 more fishes to the game which you can only get by using special baits. Example: 2 fish in the game can be only caught using a worm bait or another example 1 fish can be caught by using a rotten flesh meat. 

The rotten flesh fish is harmful and it gives nausea to the players while the rest are good for you

Hope mojang adds my idea!
