Optimization and application of an acute toxicity test with the tropical marine copepod, Acartia sinjiensis
Abstract
Currently, there are few toxicity testing protocols in Australia that use native tropical marine invertebrates.Copepods are a diverse group of zooplankton that are major components of marine food webs, and are an important food source to larger invertebrates, fish and mammals.The calanoid copepod Acartia sinjiensis is widely distributed across tropical and sub-tropical brackish to marine waters of Australia and was identified in a recent comprehensive review of marine tropical toxicity testing in Australia as a suitable test organism.This study focuses on the optimization of an acute toxicity test with A. sinjiensis, and its application in ecological risk assessments of a variety of industrial effluents.Prior to optimization, cultures produced lower numbers of animals for use in toxicity tests, and tests had a 50% failure rate due to high mortality in controls.Through refinement of culture and test conditions, including temperature, light and feeding regimes, the robustness and reproducibility of the protocol was greatly improved, with no change in sensitivity.After optimization, the EC50 ± 1SD for exposure of A. sinjiensis to copper was 33 ± 8 µg Cu/L compared to 35 ± 15µg Cu/L before.A. sinjiensis is also sensitive to other contaminants such as ammonia and phenol. This toxicity test has been used to assess the toxicity of produced formation waters (PFW) and mine tailing liquor.In PFW testing, A. sinjiensis was the most sensitive among a suite of test organisms including a tropical alga, sea urchins, oysters, prawns, and fish.The optimized test was found to be a valuable tool in the toxicity assessment of a range of anthropogenic inputs to tropical marine waters.Keywords: Calanoid; culture; effluents; ecotoxicology.
