Fishing in Pokmon Emerald is a minigame that allows players to catch Pokmon using a fishing rod. It is a fun and rewarding way to add new Pokmon to your team, and it can also be a great way to earn money. To fish in Pokmon Emerald, you will need a fishing rod. You can purchase one from the Pok Mart in any town or city, or you can find one as a hidden item in certain areas. Once you have a fishing rod, you can start fishing by finding a body of water and pressing the A button. Your character will cast their line into the water, and a Pokmon will soon bite. You will then need to reel in the Pokmon by pressing the A button repeatedly. As you reel in the Pokmon, it will struggle and try to escape. You must keep reeling in the Pokmon until it is tired, and then you can throw a Pok Ball to catch it.
There are many different types of Pokmon that you can catch while fishing in Pokmon Emerald. The type of Pokmon that you catch will depend on the location where you are fishing. For example, you are more likely to catch water-type Pokmon in a lake or river, and you are more likely to catch electric-type Pokmon in a power plant. You can also use different types of bait to attract different types of Pokmon. For example, using a lure will attract Pokmon that are attracted to food, and using a Super Rod will allow you to catch Pokmon that are normally too strong to catch with a regular fishing rod.
