Pesticides can induce changes in behavior and reduce the survival chance of aquatic organisms. In this study, the toxic effects of glyphosate suspension (Glyphosate Aria 41% SL, Tehran Iran) on behavior and tissues of common carp (Cyprinus carpio) were assessed. For this purpose, a 96 h LC50 of glyphosate suspension (68.788 mL·L−1) was used in the toxicity test. All individuals were divided into control and treatment groups with four replicates. Exposure operations were performed under two conditions: increasing concentration of suspension from 0 to 68.788 mL·L−1; then, decreasing to the first level. The swimming pattern was recorded by digital cameras during the test and tissue samples were collected at the end of the test. There were significant differences between the swimming pattern of treated individuals and control ones during both steps. The sublethal concentration of glyphosate led to hypertrophy, hyperplasia and hyperemia in the gill of fish. However, changes were obvious only after sampling. The exposed fish also displayed clinical signs such as darkening of the skin and increasing movement of the operculum. Moreover, glyphosate suspension affected swimming patterns of fish suggest that the swimming behavior test can indicate the potential toxicity of environmental pollutants and be used as a noninvasive, useful method for managing environmental changes and assessing fish health conditions by video monitoring.

“…According to previous studies, only 1% of pesticides act on target pests, while the remainders (99%) are discharged into the environment, where they may be toxic for nontarget organisms [4]. Tis matter is so important for aquatic life, since aquatic environments are the last station of pollutants [5]. Although biological methods are developing as environmentally friendly ways to control pests, the use of chemicals is still unavoidable due to the extent of agricultural lands throughout the world [6].…”

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

“…The most toxic form of ammonia is NH 3 which can increase by increased pH and temperature but decreases with high salinity levels (Kır & Öz, 2015; Sampaio et al, 2002; Sinha et al, 2015). Ammonia toxicity impairs the respiration capacity of gills when nitrite reaches the blood causes the oxidation of hemoglobin, resulting in the production of methahemoglobin (Shrivastava et al, 2019; Yalsuyi et al, 2021). In severe nitrite toxicity, the produced methahemoglobin reduces the blood ability to carry oxygen, leading to hypoxia features, thereby high mortality (Gomez Isaza et al, 2020).…”
