“…Similarly, the study of Rajabiesterabadi, et al. (2020) demonstrated that the antioxidant effects of OLE improved antioxidant enzymes of fish at transcriptional levels. Additionally, antioxidant agents are capable of increasing fish RBC resistance in hypotonic mediums, which may be due to the protection of membrane fatty acid stability (Yang et al., 2013).…”

“…Among them, olive leaf extract (OLE) contains phenols, polyphenols, flavonoids and essential oils which act as an alternative to antibiotics in aquaculture (Zemheri‐Navruz et al., 2019). Resultingly, the inclusion of OLE in the diet of common carp displayed enhanced growth performance, digestive enzyme activity, immunity and resistance against infectious diseases (Rajabiesterabadi et al., 2020; Rajabiesterabadi et al., 2020; Zemheri‐Navruz et al., 2019). The addition of OLE enhanced the antioxidative capacity and upregulated the antioxidative‐related genes in common carp (Rajabiesterabadi, et al., 2020; Zemheri‐Navruz et al., 2019, 2020).…”

Alteration of haematological and antioxidant parameters in common carp ( Cyprinus carpio ) fed olive ( Olea europea ) leaf extract after exposure to Danitol ^®

The present study aimed to assess the benefits of dietary olive (Olea europea) leaf extract (OLE) on haematological, biochemical and antioxidant parameters in the blood and livers of common carp (Cyprinus carpio) exposed to the pesticide Danitol®. Four treatments were carried out: (a) fish fed the control diet for 37 days (control); (b) fish fed the control diet for 30 days, followed by 7 days of exposure to 0.05 mg/L Danitol®; (c) fish fed the E1 diet for 30 days, followed by 7 days of exposure to 0.05 mg/L Danitol® (1 g/kg OLE); and (d) fish fed the E2 diet for 30 days, followed by seven days of exposure to 0.05 mg/L Danitol® (2 g/kg OLE). Exposure to Danitol® significantly decreased red blood count (RBC), haematocrit, haemoglobin, plasma and hepatic catalase (CAT), and superoxide dismutase (SOD) activities. However, the pesticide increased plasma alanine aminotransferase (ALT), aspartate aminotransferase (AST), alkaline phosphatase (ALP), and plasma and hepatic malondialdehyde (MDA) contents. The RBC showed lower resistance against hypotonic osmotic shock, as established by the osmotic fragility test. OLE administration restored the changes caused by Danitol®, of which the most pronounced effects were observed in the fish fed 2 g/kg OLE. We may conclude that Danitol® exposure causes oxidative stress, yet provide protection against numerous adverse effects through the supplementation of olive oil extract (OLE), resulting in a higher red blood cell count.

“…Several researches have shown that dietary herbal immunostimulants change leucocyte differential count along with change in other humoral immune parameters (Adel et al, 2015, 2020; Nya & Austin, 2009a, 2009b); however, it is not the case for all studies. Dietary supplementation with O. europea leaf extracts (Rajabiesterabadi et al, 2020), Lavandula angustifolia (Yousefi et al, 2020) and Allium cepa mill (Akrami et al, 2015) had no significant effects on leucocyte differential count, but changed humoral immune parameters in different fish species.…”

Aquaculture has an important role in global protein supply all over the world, and rainbow trout, Oncorhynchus mykiss, is one of the most important coldwater fish species in aquaculture industry. Rainbow trout global production exceeded 800,000 tons in 2017, which more than 20% of this value has been related to Iran (FAO, 2019). Due to its importance, extended researches have been conducted on nutritional aspects of this species. Nutrition is an important factor in aquaculture, because it directly affects fish growth and health as well as the farm profitability (Abdel-Tawwab, 2016). As a result, finding nutritional methods to augment fish health is worthy. Among different feed additives, dietary herbal additives showed promising health-boosting effects in fish (Abdel-Tawwab, 2016;, 2019. For example, herbal additives may improve haematological parameters in fish, because they are antioxidant and prevent haemolysis

The response of lufenuron‐ And flonicamid‐exposed Cyprinus carpio to saltwater challenge: Study on ion‐regulation and stress genes expression and plasma antioxidant characteristics

2020

Two groups of juvenile common carp (Cyprinus carpio) were exposed to sub‐lethal concentrations of lufenuron (0.11 mg/L) and flonicamid (0.43 mg/L) for 21, followed by exposure to saltwater (12 g/L). The fish were sampled before saltwater exposure (i.e. after 21 days exposure to the pesticides) and 24, 72 and 120 hr after the saltwater challenge. Plasma antioxidant characteristics and the expression of gill osmoregulatory and stress genes were studied. The results showed that Na+/K+‐ATPase gene expression of the lufenuron‐exposed fish was higher than the flonicamid‐exposed one. However, there were no significant differences in Na+/K+‐ATPase gene expression between the pesticides‐exposed fish and the control group. Both lufenuron and flonicamid increased the expression of cortisol receptor gene. Cortisol receptor expression increased 24 hr after the saltwater exposure and decreased afterwards. HSP70 gene expression of the pesticides‐exposed fish showed no significant difference compared to the control group; however, the salinity challenge caused significant elevation in HSP70 gene expression at 72 and 120 hr. Plasma SOD activity of the flonicamid‐exposed fish was significantly lower than the control fish, before the saltwater exposure; however, an inverse pattern was observed 24 hr after that. Compared to the control fish, plasma CAT activity and MDA levels increased in the pesticide‐exposed fish after the saltwater exposure. In conclusion, exposure to lufenuron and flonicamid increased cortisol receptor gene expression, which indicates stress induction. Both pesticides induced oxidative stress, before and after the saltwater exposure.
