You go to Celestic Town, Register your Super Rod and fish. You can catch the Corphish with a Rarity of 30%.
You need to evolve it from Corphish and to find a corphish you need to go to the route just left of Mauville City and go to where the pond is, surf then fish with super rod. You will easily find a Corphish at around lv30. If you just level him up once, he will evolve.
Lotad turns into a Lombre which is pretty much a water Pokemon and being very good. Another is Marill and Corphish. (There's also of course Kyogre, but he's a bit harder to find and catch)
