dc.description.abstract The ichthyofauna of the Thukela Estuary, a small (55 ha), shallow (<1_5 m) system on the KwaZulu-Natal coast (mean annual river runoff of 3865_106m3, from a large catchment of29 000km2, is seasonal: peak inputs occurring between November and March), was dominated by the juveniles of marine taxa that used the estuary as a nursery area. A striking feature of the above community was the decline in fish abundance with increasing river input, with flow values >100m3 s_1 leading to increased loss of species from the system. This decline was linked to the lack of saline intrusion into the estuary and increased freshwater flooding through the system. en
