It would be great if we'd still have access to it, I end up never choosing the Ban/Regulate options, because Pisciculture is too good to pass on, especially when I end up with naval-focused empire. Maybe 'Whale Fishing' could be replaced in case of Ban/Regulate with some tourism-oriented infrastructure that gives some scraps of influence per harbor, but still opens up the Pisciculture? Don't know how hard that could be to do.

Thanks for replying. Frankly, I am sorely disappointed in this game, but at least your team is going in the right directing in making the necessary changes to it.
