14 March 2022, Kolambugan, Lanao del Norte, Philippines - Paolo E. Bueno, 16, poses for a portrait on the fish pen he works on from time to time. The pen holds about 20.000 bangus (milkfish) which takes about four months to grow from fingerlings to a marketable size. Fish pen is the term mostly used locally for a facility that is stationary with bamboo stakes hammered into the sea bed. Fish cages are most often free floating in deeper water.
