Port Dover

From the rules:

Once, the small village of Port Dover, situated on the north shore of Lake Erie, harboured the world's largest fresh water fishing fleet. Now, become one of the local captains deploying fishing tugboats and vying for the precious freshwater fish.

Essentially, a set collecting / stock manipulation game, players collect "fish" or cubes in 5 different colors. To collect fish, you send out your boats to one of five ponds. Usually, when you dispatch a boat to a pond, you change a fishes vaule and move a fish to a different pond. After three rounds, players score for the value of any fish type for which they have the majority.
