Fishers catch dagaa at night using bright lights to draw the tiny fish to the surface of Lake Victoria before netting them.
Tiny silver Lake Victoria sardines are sun-dried on woven mats by the thousands, then fried with onion, tomato and sometimes ground peanuts to make a crunchy, salty side dish eaten over ugali. Mwanza is the biggest dagaa trading hub on Tanzania's shore of the lake, and the fish's smell fills its lakeside markets.
