We took a "short" 2+ hour drive from Dubrovnik to Kotor, in Montenegro today. The Bay of Kotor is a UNESCO World Heritage Site, and even our short visit clearly showed the importance of this area. Both images are in the direction of abstract.
We saw a lot of aquaculture happening in the Bay of Kotor. This first image shows fish farming pens.
The second is shellfish farming with the buoys supporting the lines that the shellfish grow on
Here is a shot of part of the Bay of Kotor. The fish / shellfish farming was taking place to the right of where this shot was taken from.
