Evaluation of Histopathological and Hematological Effects of Neonicotinoid (Acetamiprid 20% SP) on Grass Carp (Ctenopharyngodon idella)

Pesticides are usually used as an effective tool to control pests in agriculture; however, these chemicals may be a threat nontarget organisms, especially aquatic because environments the last station of pollutants. The present study evaluated toxicity commercial formulation neonicotinoid (acetamiprid 20% SP) systematic pesticide on survival, hematology, and histology grass carp (Ctenopharyngodon idella). For purposes, 105 fingerlings with average body weight 30 ± 2 g were exposed 0, 50, 100, 150, 200 mg·L−1 acetamiprid for 96 h. According data, clear mortality was observed concentration elevated ( P < 0.01 ). LC50 h 121.146 mg·L−1. hematological parameters fish changed, following exposure id="M2"> 0.05 Also, strong correlation found between concentrations stress bioindicators such glucose, total protein, albumin, cholesterol id="M3"> There not significant tissue damage group (0 acetamiprid); led tissues lesions hypertrophy, hyperplasia, uplifting gill filaments, necrosis epithelial cells, pyknosis karyorrhexis liver hemorrhage cell. Finally, acetamiprid-exposed exhibited some clinical signs including unbalanced swimming near water surface, increasing operculum movement, deaths open-mouthed. results clearly showed survival-reducing effects C. Idella, which return induced by pesticide. can base future studies environmental management.
