The boat rocked back and forth gently with the waves, the cawing of distance seagulls filling your ears. You were alone, though that wasn't an unwelcome thing. You often fished by yourself; it gave you time to relax and do things the way you wanted to do them. Your boat was fairly small, but you didn't mind that either. That made it easier to control.
As you cast your net into the water, you sit back on one of the benches in the boat, soaking in the sun. Roughly twenty minutes, you decide to reel in the net. Standing, you walk to the pulley on the end of your boat and begin to tug on the rope.
Suddenly, your boat lurches forward and you stumble to keep your balance as water splashes into the boat. You'd obviously caught something large, which was weird considering the waters you were fishing in at the moment were known for their smaller species of fish. Whatever it was though, you refused to let it get away.
As you tugged, whatever was in your net thrashed, attempting to pull the net lower into the water below. Digging your heels into the wood of the boat, you yank backward, hissing as the rope burns against your palms. The fucker was strong. While you've dealt with strong fish, they were nothing in comparison to this.
After a long back-and-forth fight, it seemed the fish grew fatigued, finally allowing itself to be pulled up to the surface. The boat rocks back and forth heavily as you sling the net into it. A few moments go by as you just hunch over, catching your breath. Eventually, you turn your attention to the net, your eyes going wide.
Inside the net, along with the several smaller fish that are flopping around, is a person. Well, a mermaid- or merman. Quickly, you undo the net, allowing him freedom. He stares at you in shock just as you're doing to them.
You blink. "What the fu—"
They cut you off with a hiss, ungracefully flopping backward. With his sharp teeth bared, you suddenly realize that this is a siren. You'd caught a siren.
"¡Mira dónde pescas, cabrón!" he snaps.
