Tissue-specific Histopathological alterations in Catla catla following exposure to Acetamiprid 20% SP

Abstract

Nowadays, the worldwide widespread use of pesticides enhances the likelihood of unfavorable toxicity to creatures other than the target pest. Pesticides are a major concern around the world, as they can bioaccumulate into different fish tissues, which will consequently result in serious health concerns for the consumers. In this context, the present study depicts several serious histopathological alterations of vital tissues of freshwater fish Catla catla exposed to Acetamiprid 20% SP at a lethal (50 mg/L-1 for 96 hours) and sub-lethal concentration for 1, 4, and 8 days. However, it is strongly suggested that Acetamiprid 20% SP is moderately toxic to Catla catla. The fish's evident histological alterations are a high degree of pathological lesions. The examination of the gills indicated fusion, epithelial degradation, vacuolation, hyperplasia, and deformity at the tips of secondary lamellae, and tissue destruction at the epithelial site have all been seen as lesions. Infiltration of leucocytes, atrophy, breaking of muscle fibers, and vacuolation-like changes in the muscles were observed.
