You'll need to use Basculegion to catch Alpha Gastrodon, as they are on one of the islands at Seagrass Haven. Circle the island and get off on the side where the patch of grass is.

The only other Pokemon you need to worry about are in the water, so don't be afraid to take your time in catching the Alpha Gastrodon!

How to Catch Alpha Gastrodon

Use Smoke Bombs and Razz Berries

The most important skill for catching wild Pokemon is being able to lure them with berries so that you have a clear shot on their back. Razz Berries make Pokemon easier to catch, so when combined with Heavy/Leaden/Gigaton Balls, they can make it very easy to catch Alpha Pokemon.

Alternatively, you can also use a Stealth Spray to sneak up on the Alpha.

Repeatedly catch them unawares

This method of catching a Pokemon allows you to make use of the fact that your character can move freely during battle. Since it only involves going into battle, it requires less precision than the method that involves Smoke Bombs and Razz Berries.

Additionally, this method allows you to continuously have the Alpha Pokemon be caught unawares, so even if your Pokemon is at a much lower level than the Alpha Pokemon, you'll be able to damage them, run, catch them unawares, then repeat in a loop until their HP is low enough to easily catch them.
