Crab Clues

De rumors are true. No matter what we try, we aren't netting as many crabs as before. And de ones we do catch taste wrong, even making some of my people sick! I succeeded my mother's position as head river-walker after losing her to de Twilight's Blade. Dealing with dis famine, my new duties, and my grief... It's so much for me to bear. Dis is de area where we first noticed an issue with our crabs. Can you investigate for me while I make more traps?
