| Abstract: | Toxicity tests reveal that the zebrafish (Brachydanio rerio) is very sensitive to malathion, an organophosphorus insecticide, and 24 to 96-h LC50 values showed a gradual decrease as the exposure time was increased. Zebrafish exposed to long-term sublethal concentrations failed to spawn and invariably exhibited skeletal deformities. Possible causes of the reduced gonadosomatic index and skeletal deformities are discussed. |
