The predatory impact of invasive alien smallmouth bass, Micropterus dolomieu (Teleostei: Centrarchidae), on indigenous fishes in a Cape Floristic Region mountain stream
Fish populations in the Rondegat River, a mountain stream in the Olifants-Doring system in the Cape Floristic Region, South Africa were surveyed to assess the impact of predatory alien invasiveExpand
The impact of trout on galaxiid fishes in New Zealand
It is argued that managers should be more proactive in their response to the plight of galaxiids, and avenues of research are identified that will benefit native fish conservation activities in the future. Expand
The impact of invasive fish and invasive riparian plants on the invertebrate fauna of the Rondegat River, Cape Floristic Region, South Africa
Investigation of the impact of invasive smallmouth bass and black wattle on assemblages of macroinvertebrates and fish in a cobble-bed foothill river indicates that smallmouthbass, in contrast to indigenous fish, do not exert a strong influence on the abundance of their invertebrate prey. Expand
Threatened Endemic Fishes in South Africa's Cape Floristic Region: A New Beginning for the Rondegat River
The successful treatment culminated from a decade-long process that was facilitated through collaboration among a South African nature conservation authority, the South African Institute for Aquatic Biodiversity, and the American Fisheries Society Fish Management Chemicals Subcommittee. Expand
Optimising invasive fish management in the context of invasive species legislation in South Africa
Background : South Africa hosts a large number of non-native freshwater fishes that were introduced for various industries. Many of these species are now listed under the National EnvironmentalExpand
A preliminary assessment of the impact of alien rainbow trout (Oncorhynchus mykiss) on indigenous fishes of the upper Berg River, Western Cape Province, South Africa
Impacts of alien rainbow trout (Oncorhynchus mykiss) on critically endangered Berg River redfin (Pseudobarbus burgi), Cape kurper (Sandelia capensis) and Cape galaxias (Galaxias zebratus) in theExpand
Immediate impact of piscicide operations on a Cape Floristic Region aquatic insect assemblage: a lesser of two evils?
Given that alien invasive fish negatively affect both fish and aquatic insect communities in South Africa, the long-term positive conservation impact of removing these fish is likely to outweigh the short-term negative effects of the piscicide. Expand
Managing conflict-generating invasive species in South Africa: Challenges and trade-offs
Background: This paper reviewed the benefits and negative impacts of alien species that are currently listed in the Alien and Invasive Species Regulations of the National Environmental Management:Expand
Evidence of source-sink metapopulations in a vulnerable native galaxiid fish driven by introduced trout.
Investigation of Galaxias vulgaris populations in New Zealand found that trout, rather than habitat, drove recruitment failure, and trout-free reaches appear to act as sources in a river network but are susceptible to future invasions by trout. Expand
Spatial extent and consequences of black bass (Micropterus spp.) invasion in a Cape Floristic Region river basin
Black bass (Micropterus spp.) are invasive fish that have adversely affected native fish communities in many regions of the world. They are known to threaten native fishes in the Cape FloristicExpand
