Hello fellow fishermans and farmers!

How can i use fish hatchery at Windstadt Manor? I mean can i put catched fishes into it????
For now i have only slaughterfish eggs there.
If i catch a fish , can i drop her into the fish hatchery???

Yes, go to the end of the dock and cursor over the stonework, self explanatory from there.

You activate the fish hatchery and place the fish you want to breed in there (you only need one of each species). Every once in a while, fish of the same species as what you currently have placed in the hatchery will then spawn in the water within the netted area.
