Why is my DexNav saying I haven't caught all the Pokemon on Dewford-106-107?

Question

I don't have surf or any rod except the old rod, and I checked those routes and Dewford and there is no grass, only fishing Pokemon, and I've already caught all the ones it says are there for the old rod(Tentacool and Magikarp) Am I missing something?

Comments

Also, if this matters, specifically, I'm playing OR

Answer 1

This is because you get Wailmer with the Good Rod only. Also, there are Pokemon you can obtain by surfing. There are also hidden encounters you can only access once you've defeated or captured Groudon or Kyogre.

Route 106's full list of Pokemon

Route 107's full list of Pokemon

Okay, I knew that, but I thought it didn't count those pokemon until you had the ability to get them, like with the bronze and silver stars, or do those mean something else.
