Histopathological Changes of Rainbow Trout (Oncorhynchus mykiss) after Exposing Sublethal Composite Nitrogen Fertilizers

摘要

Subchronic toxicity of composite inorganic fertilizers such as ammonium sulfate, composite fertilizer 15-15-15, and composite fertilizer 25-5-10 on the skin, liver, kidney, pancreas, digestive system and gills of the juvenile rainbow trout (Oncorhynchus mykiss) was studied in two weeks toxicity tests under static-renewal test conditions. Histological lesions were observed in skin, liver, kidney, pancreas, stomach, and gills of the fish. In order, the most effected organs were skin, liver, and kidney.
