it's not catching. just follow the story. Magma Emblem, Magma base... Slateport ship... Lilicove, Aqua Base.....
no more wailmer!!
You get wailord in route 129 or evolve your wailmer into a wailord.
In emerald, there is a slim chance you'll catch one in Route 129, but the easier way is to catch a Wailmer and evlove it.
They are rare if you surf on Route 129. It's much easier to catch a Wailmer and evolve it into Wailord.
Rather than catching a Wailmer at Lv. 40, you can find one by surfing on Route 129 or Fishing on Route 136 with the Super Rod. (though they're very rare, I'd say evolve Wailmer) You can catch a wailord at route 129 by super rod. Their level could be very high, although i met a lvl 28 wailord there by accident.
route 129 use super rod
evolves from a wailmer catch wailmes surfing rt 129
lvl 40 or find wailmer on route 129 (surf)
You must evolve wailmer/surf and find one on route 129. There are few there. Wailmer will evolve at level 40.
If you want to catch a wailord you have to catch a wailmer first. And then get wailmer to evolve at level 40. You can also catch a Wailord on route 129 on emerald. You can catch a wailmer on routes 103, 105, 106, 107, 108, 109, 110, 115, 121, 122, 123, 124, 125, 126, 127, 128, 129, 130, 131, 132, 133, 134, and 135.
