Fishery

The Fishery supplies your city with food. It is normally built in conjunction with the second quest, Construct a Fishery. You can only build the fishery on shore regions with the blue banner. Building the fishery and completing the quest gives you a profit.

Options
Like other resource structures, the only option for the fishery is upgrading 4 productions lines. If you upgrade them they will boost the output of food coming from the Fishery.
