Simple. Get the rod from a fisherman in a house in Mossdeep. Then, face any body of water, just not the puddles in some places. Press start, go to bag, go to key items, and it should be there. Choose it, press use, and wait. If it says you have a bite, press A. Try it again if you don't get a bite. Sometimes Pokemon will get away. It takes a longer time to reel in big catches. The little ones are usually Magikarp. When you catch something, you will go into battle with it. You can catch it with a pokeball. I suggest catching them with net balls or dive balls since they are all water Pokemon. Hope I helped! :)
if you have one whitch you get in the battle zone you walk up to water a sea of river then go on key items press A to the super rod then go on use (u need to face the water) then when you get a bite press A once or twice then if you were quick enough you will fight a Pokemon
