Item type: Journal Article • Journal: African Journal of Aquatic Science • Authors: PSO Fouché --- Zoology Department, South Africa RG Heath --- Golder Associates Africa, South AfricaThe Xikundu fishway, in the Luvuvhu River near Thohoyandou, was monitored for 23 months in 2004–2006. Adults and juveniles of 60% of the expected fish species were collected in the fishway, and two major upstream migrations occurred. Most Labeo and... -
