Compilation of the local articles on the toxicological experiments by using the freshwater fishes as subject for the study has revealed some 66 reports, containing 527 cases and involving 22 fish species of 10 families. The chemical agents are 96 in number, 40.9 % of which are classified as the insecticides. Most (81.9 %) of the study cases are acute static bioassay. The well known and commercially important food fishes of the species Cyprinus carpio (Linn.), Tilapia nilotica (Linn.) and Puntius goniotus (Bleeker) are commonly selected as the tested animals. An evaluation on the suitabilities based on the available biological data and toxicant sensitivity of all the fishes in use indicates that Labeo frenatus (Flower), Epalzeorhynchos bicolor (Smith) and Poecilia reticulata (Peter) may have a good potential for borth chronic and acute bioassays. Sensitivity fishes of economic value such as P. gonionotus (Bleeker), Pangasius sutchi (Flower) in their early stages are possibly suitable for the acute toxicological study. Whereas Morulius chrysophekadion (Bleeker) and Lates calcarifer (Block) are biological and practically unfit for the study. Descriptions of nine interesting species of the fishes are buifly given, and reviewed testings are cross-referenced by chemicals and by fishes.
