Unfortunately, the best catches are made during the rainy season when drying is difficult resulting in lower quality of the dried product. The lowest quality is however still usable as chicken feed. Drying is often done on the sand, on rocks or on old nets spread on the grass. Drying racks have not caught on, neither have salting or smoking. The dried fish is packed in sacks and traders take the fish to the market. A major wholesale market for dried dagaa is in Mwanza, Tanzania, and Kisumu Kenya, from where it is transported all over eastern and southern Africa for use as food or chicken feed. Sometimes it competes with dried

The silver cyprinid breeds throughout the year with two peaks, the first in August and the second in December-January. It is fast growing and reaches sexual maturity at ages which vary from 16 to 25 months.

The silver cyprinid has a lake-wide distribution covering both inshore and offshore in Lake
Victoria. It normally occurs between 0 and 20 m (0–66 ft) in depth, although both eggs and fry can be encountered as deep as 68 m (223 ft). The adult fish stay close to the bottom in
