Pokémon Diamond Version, Pearl Version, and Platinum Version - Fishing
Each area has a specific fishing success rate for each rod, for example, 50%. Once the player has the rod ready, the game waits about 3 and a half seconds. At the chance given by the success rate, an exclamation point appears over the player, at which point the player must press the A button within the next second to land the Pokémon, or the Pokémon will get away. The fishing attempt will also fail if the player presses the A button too soon while fishing.
Because of a bug, the Sticky Hold and Suction Cups abilities have no effect during the fishing process in Pokémon Diamond Version, Pokémon Pearl Version, and Pokémon Platinum Version. In Pokémon HeartGold Version and Pokémon SoulSilver Version, both abilities double the fishing success rate if the first Pokémon in the party isn’t an Egg and has either ability.
