Weatherfish (Misgurnus fossilis) as a new species for toxicity testing?

Original language description

Selection of appropriate test species is a critical issue when assessing effects of environmental contam-ination on fish because the ecological relevance of commonly used test species might be restricted due to their exotic origin. In the present study, a European freshwater fish with frequent occurrence in agri-cultural areas is suggested as a potential alternative: the European weatherfish (Misgumus fossilis). Its suitability for acute embryo toxicity tests (FET) was investigated with regard to practical implementa-tion, sensitivity to contaminants and tolerance against environmental conditions of concern. For this purpose, weatherfish embryos were exposed (72 h) to the reference substance 3,4-dichloroaniline (DCA) in three independent tests. Furthermore, the effects of dissolved oxygen (DO) deficiency on weatherfish embryos were studied to evaluate their suitability e.g. for sediment bioassays. Obtained results revealed that the sensitivity of weatherfish embryos towards DCA (72 h-EC50 = 0.52 mg/I; 72 h-LC50 = 0.71 mg/I) was highest compared to other species and three times higher than that reported for the commonly used zebrafish (Danio rerio). Even though knowledge of DO requirements during the embryonic period of European fish species is scarce, weatherfish can be stated as one of the most tolerant native species (LC90 for DO = 0.53 mg/I after 48 h exposure plus 72 h post-exposure). Its high ecological relevance for Europe, the particular sensitivity towards DCA and high tolerance against DO depletion highlight the potential of weatherfish as additional species for toxicity testing.
