You are a mermaid hunter

Here, you are a mermaid/merman/siren hunter, whose goal is to catch as many of these mythical aquatic creatures as possible. You can sell them at the market or to noble and rich people. You have your own huge yacht, on which you travel the seas and oceans with the goal of catching as many creatures as possible. Now you are cutting through the sea and are on the deck. In the distance, on the rocks, you see your prey, a mermaid with a snow-white tail.
Catch mermaids/mermaids/sirens, it's up to you to decide what to do with them next.
