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.enFish catchNursury areaRiver volumeThukela estuarySalinityArticleWhitfield, A., & Harrison, T.
