Wanink, J.R. (1996) The small pelagic Rastrineobola argentea: successful survivor in Lake Victoria. Naga, the ICLARM Quarterly, 19(1), p. 48.
The small cyprinid dagaa (Rastreneobola argentea) is the only indigenous species from Lake Victoria which still supports an important fishery after the population boom of the introduced Nile perch (Lates niloticus), while at the same time it is a major prey species of the perch. The observed life-history tactics and the shift from juvenile to adult exploitation mortality made dagaa a successful survivor in a disrupted ecosystem. Although the prospects for a sustainable fishery are good, the current increase in the use of mosquito seines is dangerous. Not only do mosquito seines yield a lower catch per unit of effort than alternative gear, but they also show a strong selection for juvenile dagaa.
