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.
