“…Furthermore, our result agreed with those reported by CA Laetz, DH Baldwin, TK Collier, V Hebert, JD Stark and NL Scholz [ 82 ] who indicated that histopathological damage to the liver, pancreas, and intestine may result in decreased feed digestion and metabolism efficiency because these tissues play critical roles in the regulation of biochemical parameters, particularly proteins, lipids, carbohydrates, and hormones, as well as the synthesis and secretion of digestive enzymes. Other important factors that explain the delay in fish growth could be the transformation into the energy of a portion of nutrients from the digestion of feed consumed to cope with chemical stress that constitutes the exposure to agricultural pesticides [ 83 ] . The highest reduction in growth in the combined agrochemical exposed group may be attributed to a synergistic impact between glyphosate and malathion; this effect could be explained in light of the fact that binary pesticide combinations generated synergistic acetyl-cholinesterase inhibition [ 82 ].…”

Background Pesticide exposure is thought to be a major contributor to living organism health deterioration, as evidenced by its impact on both cultured fish species and human health. Commercial fish diets are typically deficient in selenium (Se); hence, supplementation may be necessary to meet requirements during stress. Therefore, this study was conducted to investigate the protective role of selenium yeast (SY) supplementation for 60 days against the deleterious effects of glyphosate and or malathion chronic toxicity at sublethal concentrations in Oreochromis niloticus . Methods Two hundred and ten fish were divided into seven groups (n = 30/group) as follows: G1 (negative control); G2 (2 mg L− 1 glyphosate); G3 (0.5 mg L− 1 malathion); G4 (glyphosate 1.6 mg L− 1 and malathion 0.3 mg L− 1); G5 (glyphosate 2 mg L− 1 and SY 3.3 mg kg− 1); G6 (malathion 0.5 mg L− 1 and SY 3.3 mg kg− 1); and G7 (glyphosate 1.6 mg L− 1; malathion 0.3 mg L− 1 and SY 3.3 mg kg− 1). Results Results revealed significant alteration in growth performance parameters including feed intake (FI), body weight (BW), body weight gain (BWG), specific growth rate (SGR), feed conversion ratio (FCR), and protein efficiency ratio (PER). G4 has the highest documented cumulative mortalities (40%), followed by G3 (30%). Additionally, the greatest impact was documented in G4, followed by G3 and then G2 as severe anemia with significant thrombocytopenia; leukocytosis; hypoproteinemia; increased Alanine aminotransferase (ALT) and Aspartate aminotransferase (AST), urea, and creatinine, as well as malondialdehyde (MDA), superoxide dismutase (SOD) and glutathione peroxidase (GPx). Considering the previously mentioned parameters, selenium yeast (Saccharomyces cerevisiae) (3.3 mg kg− 1 available selenium) mitigated the negative impact of both the agrochemicals, whether exposed singly or in combination, in addition to their antioxidative action. Conclusions In conclusion, our study found that organophosphorus agrochemicals, single or combined, had negative impacts on Oreochromis niloticus regarding growth performance, biochemical and hematological changes in the serum, as well as induced oxidative damage in liver and kidney tissues. Supplementation of SY at the rate of 3.3 mg kg− 1 diet (2.36 mg kg− 1 selenomethionine and 0.94 mg organic selenium) ameliorated the fish performance and health status adversely affected by organophosphorus agrochemical intoxication.

“…The increased energy used by S. senegalensis exposed to lower 4-MBC through increased swimming distance can be associated with effects on energetic budget. In fact, effects of chemical stressors on energetic balances have already been reported (Agbohessi et al, 2014;Rabasa and Dickson, 2016;Anacleto et al, 2018). Such excitatory swimming response after 4-MBC exposure may also have later implications on growth or successful feeding and reproduction.…”

Many personal care products integrate UV-filters, such as 4-methylbenzylidene camphor (4-MBC) which has been detected in aquatic habitats. Possible effects of 4-MBC to aquatic organisms have been poorly studied. Therefore, the main objective of this work is to study the effects of 4-MBC exposure to Solea senegalensis during metamorphosis, a sensitive life stage of this flatfish. To achieve this, at the beginning of metamorphosis (13 days after hatching, dah) fish were exposed to 4-MBC (0.2–2.0 mg L− 1) for 48 h. After this period, fish were transferred to clean medium and were fed and maintained until more than 80% of fish in control group completed the metamorphosis (24 dah). Mortality, malformations and metamorphosis progression were studied on a daily basis. In addition, growth, behavior and biochemical markers of neurotransmission (acetylcholinesterase, AChE), oxidative stress (catalase, CAT; glutathione S-transferase, GST, and lipid peroxidation, LPO) and anaerobic metabolism (lactate dehydrogenase, LDH) were determined at the end of the experiment. An acceleration of metamorphosis progression was observed during and 2 days after the 4-MBC exposure in all concentrations tested. In addition, decreased length, inhibition of CAT activity and induction of oxidative damage (LOEC = 0.928 mg L− 1 4-MBC for length, CAT and LPO) were observed. A short-term exposure to 4-MBC at the onset of metamorphosis, a critical period of development, affected S. senegalensis at several levels of organization, even after nine days in clean medium, including growth and metamorphosis progression, suggesting possible long-term adverse effects to this species.

For a meaningful interpretation of toxic effects in fish, knowledge of sub-lethal events is essential and for this reason, we have conducted a series of studies with a relevant environmental concentration of a mixture of herbicides; Atrazine, simazine, diuron and isoproturon (ASDI) pollutants and using immune (Fatima et al. 2007) and endocrinological changes as principal endpoints under controlled laboratory conditions. Goldfish (Carassius auratus) were exposed to a cumulative concentration of 50µg/l of ASDI mixture for 12 weeks which was reported above the permissible level in the drinking water of Belgium (EAEW report, 1998) and nearby aquatic environments, confirming some of these herbicides still persistence despite restriction policies (Pesce et al. 2010;Agbohessi et al. 2014).Control and exposed fish were sampled at week-4, 8, and 12. We investigated the endocrine modulatory effect of ASDI which shows a low degradation rate in water. Thus, at the realistic level of ASDI concentration, significantly increased levels of cortisol and aromatase after 4-weeks were recorded. Reduction in aromatase activity at 8 and 12 weeks is followed by estradiol (E2) showing a positive correlation between them. Hence, 11-Keto reduced significantly at 4-8 weeks and enhanced at 12 weeks. Remarkable reduction in E2 and 11-Keto may be correlated with the reduced egg production in stressed fish by these herbicides. However, no remarkable change in testosterone is observed at 4 and 12 weeks as compared to the control. ASDI mixture treatment induced remarkable induction in vitellogenin (Vtg) biomarker protein in male stressed fish. Furthermore, it may confer that modulation in the pathway of the reproductive cycle may alter the gamete quality, quantity and consequently may disrupt spawning and mating behaviour in fishes even at a realistic level of pollutant in the environment.
