The Legend of Zelda: Ocarina of Time 3D Tips

Catch the fish immediately/easier
Go to the fishing pond and get your rod. Go to the demolished dead tree thingy and climb on it. You can see the fish being close. Cast your line, but make sure you press B button enough times to make it just like you lowered the bait into the water and nothing else. As soon as a fish bites, it should display the scene when you caught a fish, but if this doesn't happen, you at least have higher chances of catching that fish. Good if you want to catch a fish that weights a lot of pounds, or even catch the Hyrule Loach. (which is difficult to catch; I caught it only once.)
