Sabie River Justices league
The Sabie River is currently the most pristine river in South Africa, due to its high biodiversity and re-establishment of migratory pathways of ecologically important fishes. The presence of tigerfish and yellowfish is a good indicator of a free-flowing river navigable by fish, which is important for the survival of ecosystems. Acoustic tags are special technological devices that send out a signal like a “ping” in the water that is picked up by a hydrophone. Each acoustic tag has its own unique identification signal that we can use to track a specific fish. Therefore by having multiple hydrophones in the water we can keep of track where these tagged tigerfish and yellowfish are along the entire Sabie River. The Sabie River has both a fish ladder and a fish pass to allow fish to move past the barriers like a weir or a dam wall, but we are not sure if these structures are sufficient for fish migration and movement or if fish can, or will, use these structures. We are the first in South Africa to use acoustic tagging on rivers, and we are using it to see if these barrier bypass structures work, and if not that we can improve them. LET THE FISH SWIM!!
