And with a hatchery, there's less risk of depopulating all the fish around your base. The way it looks now, by the time I've got an Observatory there won't be any wildlife to observe.
When I play survival games like this, one of my major goals is to become as self sufficient as possible, to build a base with the infrastructure to provide for all my needs.
Exactly! I got the game yesterday and have been having a blast with it, but the small size of salt deposits make them difficult to find sometimes. Given that we're literally swimming in the stuff, seems reasonable to have a means to grab it.
