The CMU Journal of Natural Sciences is published four times a year, in January, April, July and October. The African Catfish (Clarias gariepinus) was exposed to different toxicant concentrations of 100, 200, 300, 400, 500 mg/L using a static nonrenewable bioassay method. Another set up without the toxicant was set up to serve as control. Two replicate concentrations for the different toxicants used in thirty (30 L) litres rectangular tanks were also set up. The aquariums were filled to fifteen-liter mark, loaded with ten fishes and properly labelled. Parameters such as cumulative average value of operculum movement; tail beat frequency, cumulative number of discoloration, erratic swimming, and mortality were monitored in-situ. The results showed that the lethal effect of the toxicants on the fishes depends on concentration and duration of exposure to the toxicant. Also in-situ observation showed that the cumulative average number of discoloration, erratic swimming, and mortality increased with increase in concentration and exposure time, while the cumulative average of operculum movement and tail beat frequency decreased with increase concentration and exposure time. 2020-05-20T04:41:50Z 2020-05-20T04:41:50Z 2020 Chiang Mai University (CMU) Journal of Natural Sciences 19,2 (Apr-Jun 2020), p.191-205 2465-4337 http://cmuj.cmu.ac.th/uploads/journal_list_index/514613152.pdf http://cmuir.cmu.ac.th/jspui/handle/6653943832/68663 Eng Chiang Mai University
