Using action cameras to estimate the abundance and habitat use of threatened fish in clear headwater streams
Item type: Journal Article • Journal: African Journal of Aquatic Science • Authors: B Hannweg --- , South Africa SM Marr --- , South Africa LE Bloy --- , South Africa OLF Weyl --- , South AfricaSnorkel and electrofishing surveys are the traditional baseline methods for fish surveys in clear headwater streams. However, action cameras provide a non-harmful alternative to monitor freshwater fish populations to develop informed conservation management initiatives. In this paper, estimates from photographs... -
Habitat utilisation of Pseudobarbus afer and Sandelia capensis in headwaters of the Swartkops River, Eastern Cape, South Africa
Item type: Journal Article • Journal: African Journal of Aquatic Science • Authors: B Hannweg --- , South Africa SM Marr --- , South Africa LE Bloy --- , South Africa OLF Weyl --- , South AfricaHabitat degradation is one of the greatest threats to endemic freshwater fish in the Cape Fold Ecoregion. One habitat restoration strategy is the replication of critical habitat using artificial materials. In this paper, we evaluate the habitat occupancy of two... -
Can bait improve the efficiency of underwater video monitoring of fish in headwater streams? A case study from the Rondegat River, South Africa
Item type: Journal Article • Journal: African Journal of Aquatic Science • Authors: SZ Bajaba --- , South Africa S Hugo --- , South Africa AJ van Wyk --- , South Africa SM Marr --- , South Africa NG Vine --- , South Africa OLF Weyl --- , South AfricaThe use of action cameras for underwater video sampling provides a non-harmful alternative for monitoring endangered and threatened fish populations in clear headwater streams. Here, we examine the use of baited remote underwater video systems (BRUVS) for the monitoring of...
