Note: This game includes Chinese and English instructions.

The Kuroshio is a warm Pacific current flowing northward from the equator past Taiwan to Japan. Its clear waters appear dark under the sunlight, and its swift flow attracts migratory and large predatory fish, making it a vital pillar of East Asia’s fisheries.
In this game, players take the role of fishing boats operating along the Kuroshio, gradually expanding the routes of fish schools on the table by playing cards, and catching marlins, mahi-mahi, and tuna to score points.
