 | Development of protocols for acute fish toxicity bioassays, using suitable indigenous freshwater fish species |
| Expanded Title: | The Poecilia reticulata (Guppy) test is currently the preferred fish toxicity test being used in
most South African laboratories. There are, however, several issues which hamper the
successful use of the Guppy test in bioassays (i.e. it is an exotic species and may therefore
not be representative of the fish fauna in South African ecosystems, significant variation was
detected in results between laboratories and disease result in frequent loss of brood stock).
The above emphasizes not only the need for nationally standardized fish bioassay protocols,
but also for the use of indigenous fish representing receptor organisms actually present in
aquatic ecosystems will ensure the extrapolation of meaningful, relevant and ecologically
significant results and management objectives from ecotoxicity tests. This is specifically
significant in view of the increasingly important role that toxicity-testing plays in water
resource management in South Africa. |
