I remember manginhas from my youth. It feels like a lifetime has passed since I last did this simple yet rewarding activity. This coastal tradition is deeply rooted in my province’s way of life. For me, manginhas was more than a pastime; it was a direct connection to the sea and its abundance. What is Manginhas? The Riches of the Low Tide Manginhas is the local term for coastal foraging. It involves going to the beach or shallow areas during low tide. We collect exposed marine life entirely by hand. This included various shellfish, small fish, and seaweed left behind by the receding water. I fully enjoyed this activity for many reasons. First, it meant spending a good portion of the day on the beach.
