Namiji: Aquamarine

From BoardGameGeek:

In Namiji, you are two to five fishermen of yesteryear who are about to take a journey of discovery of beautiful and wild marine life. You will need to have a fruitful day at sea to win the game. To do this, you will have the opportunity to contemplate magnificent marine species, to fish with a line or a net to fill your racks with colourful fish and haul in your crustaceans traps. Aquamarine is the first expansion for Namiji. It contains all the item stretch goals from the original Kickstarter campaign and a booklet containing the expansion's rules and the Boats' stories. The booklet is also available for download from the Namiji website. Aquamarine adds the whirlpool and additional creatures to the game. It is an expansion and cannot be played without the base game Namiji.
