外文摘要：Deltamethrin (DM) has excellent insecticidal activity and has been used worldwide. Previous stud-ies have indicated that DM in the environment is toxic to aquatic creatures. However, there is a lack of research assessing the potential threat of DM residual in feed ingredients. Since DM is a lipo-philic insecticide, It is also unknown if variations in dietary and body lipid levels might influence the toxicity and DM residues. Six different diets were formulated, each with two varying levels of lipid content and three levels of DM.The growth performance of shrimp declined as the dietary DM levels increased. When shrimp were fed a diet containing a high dose of DM, a reduction in their antioxidant capacity was observed. Additionally, the hepatopancreas and intestinal histolog-ical morphology were severely harmed by the presence of DM in the diet. DM in the diet increased the susceptibility of shrimp to pathogens and induced gut microbiota dysbiosis, disrupting the bal-ance of inter-species interactions. DM was not found in the muscle and hepatopancreas of the shrimp. In conclusion, the presence of DM in feed reduced the growth performance and antioxidant capacity of shrimp, damaging their intestinal health. DM was rapidly metabolized within the shrimp's body. ? 2023, The Authors. All rights reserved.
