Özet

The aim of this study was to investigate the sensitivity of European chub (Leuciscus cephalus, Linnaeus, 1758), a natural freshwater fish species, to a synthetic pyrethroid (deltamethrin), a carbamate insecticide (carbaryl), and an organophosphorus pesticide (malathion). This fish species was taken from Iyidere stream (Trabzon-Turkey) for bioassay experiments. The 96-h LC50 values for European chub were estimated, and their variations for each pesticide discussed. While carbaryl and malathion were less toxic than deltamethrin for European chub, the most toxic pesticide was deltamethrin (LC50: 5.34 mu gL(-1)), whereas those of carbaryl and malathion were 8.66 mg L-1 and 1.81 mg L-1, respectively.
