Yes, but the bonuses you get from your trait no longer apply. So compared to a species without the angler trait, you lose in relative value, because only the species with the Aquatic trait loses those 10% for basic resources if you go from non-Gaia to Gaia world, while everybody gains the Gaia bonuses.
Which is a really weird trade-off, and imho quite inconsistent. There are two penalties to the trait for non-wet worlds, reduced habitability and increased housing. Habitability cannot apply, since ideal worlds are locked at 100%, but housing could apply, yet it has a manual exception for ideal planets coded into the trait. The beneficial effect on the other hand don't have an exception, and as a result do not apply. There's no way you could look at the tooltip and come to the conclusion that this is how the trait works.
Imho, the bonuses should apply to ideal worlds, both for consistency, and because it would feel a lot better.
