| Abstract: | Experiments were conducted to test the effects of turbidity (10–50 NTU) and light (0–2 μE m−2 s−1) on the feeding efficiency of white bream Abramis björkna preying on Chaoborus flavicans . Increased turbidity and low light levels did not have a significant impact on the feeding of white bream. In total darkness feeding was impeded indicating that white bream depends on vision for feeding. The dominance of white bream in temperate eutrophic lakes could be attributed to their success of feeding in turbid and low light environments. |
