This mod has a dependency for Fish Farm (https://mods.factorio.com/mod/Fish_Farm), but that mod is currently not being maintained. From what I've seen in mod comments, all current Fish Farm functionality was merged into Nihilistzsche_FishFarm (https://mods.factorio.com/mod/Nihilistzsche_FishFarm). You may want to change dependency to that mod.
Either that, or go with an Optional dependency for both mods, with a note to not use both at the same time.
