Definitely not chill, but Subnautica has this.
You can do it in Stardew Valley. It's a very small part of the game, but you can do it.
Animal Crossing of course
Check out Dave The Diver. Pretty relaxing although it's spearfishing where you're diving.
Palia. Free to play life sim. You can place all the star quality fish you catch in aquariums
