How do you stop ports being built in the Caspian/Red Sea?

[Turbo]

What is the easiest way to prevent provinces bordering the red sea or caspian sea from building ports? I want to stop the AI from building fleets in these areas.

Thanks!

edit the map_regions.tga file removing the white dots (ports) in those regions. That shoul do i think

Yes, and make sure that once you've done that you delete any ports which start there from descr_strat.txt.

I don't know if there are any, but if there are...

An alternative method is to add a hidden resource, eg. 'noships', to these regions and add this as a condition to not build ships, that way you can still build ports and get the trade effects, without you or the AI wasting resources on worthless fleets.
