“…CPF toxicity can induce neurobehavioral development by inhibiting the acetylcholinesterase once metabolically activated within the organism [29]. However, the application of functional feed additives can protect fish from the impacts of pesticides, insecticides, and xenobiotics via stimulating the immune and antioxidative responses [30][31][32].…”

Due to the numerous pharmacological impacts of Spirulina platensis (SP), the effects of SP on the oxidative status of Nile tilapia farmed under chlorpyrifos (CPF) ambient toxicity were considered in this study. Fish (60 ± 6.1 g) was randomly stocked in five groups where the SP free diet was fed to the control group while the second one was fed 1% SP without CPF exposure. Additionally, CPF (15 μg/L) was added in water and fish were fed with SP at 0, 0.5, and 1% (third, fourth, and fifth groups, respectively). Samples of blood and gills, kidneys, and liver tissues were assayed for biochemical measurements. Fish exposed to CPF exhibited significant (p ≤ 0.05) increments of serum alanine aminotransferase (ALT), aspartate aminotransferase (AST), alkaline phosphatase (ALP), cholesterol, urea, creatinine, and malondialdehyde (MDA), while significantly decreased total protein, albumin, and antioxidative enzyme activities (superoxide dismutase (SOD) and catalase (CAT) were observed in tilapia exposed to CPF (p ≤ 0.05). In contrast, SP feeding resulted in decreased levels of ALT, AST, ALP, cholesterol, urea, and creatinine as well as increased total protein, albumin, SOD, and CAT activities. Based on the obtained results, it can be suggested that SP is efficient in protecting Nile tilapia from CPF toxicity by increasing the antioxidative response.

“…A decrease of lymphocytes on the 14 th day after infection indicated that antibodies were formed to fight A. hydrophila. The fight may reduce lymphocyte cell numbers, as the lymphocyte in the peripheries are allocated to the infected area 17 . Even though the lymphocytes in P1, P2 and P3 groups decreased after infection, their amount remained in the normal range.…”

Effectiveness of turmeric-enriched pellets to improve the immunity of Clarias batrachus toward motile Aeromonas septicemia disease

Background: Turmeric is known as a natural remedy to improve the immunity of organisms. This study aims to understand the effectiveness of turmeric-enriched pellets to improve the immunity of Clarias batrachus to Aeromonas hydrophila. Methods: The study was conducted from May to August 2020. C. batrachus fingerlings, 7-8 cm total length (TL) and 4-5 g (BW) at baseline, were kept in 30 L aquaria (10 fishes/aquarium; three replicated/treatment). Commercial pellets were mixed with turmeric powder. There were five treatment groups: P0 (control, no turmeric); P1 (0.5 g turmeric per Kg of pellets); P2 (0.7 g/Kg); P3 (0.9 g/Kg); Pp (positive control). Thirty days after being feed with turmeric-enriched pellets, all groups of fish were infected with 0.1 ml (108) of A. hydrophila suspension, intramuscularly. The P0 group did not receive injection, while Pp group were not fed with turmeric-enriched pellets but were infected with the bacteria. Fourteen days after infection, clinical signs and hematology of the fish were studied. Results: Pp fish showed heavy clinical signs of A. hydrophila, such as loss of balance, pigmentation, hemorrhages and ulcers. P0 fish did not show any symptoms, while the treated fish reveled some clinical signs of A. hydrophila to a lesser extent than Pp, indicating that the fish is able to face the A. hydrophila attack. Hematology for Pp fish revealed high white blood cells, indicating that the fish were infected. The blood condition of the P0 fish, as well as those of the turmeric-treated fish were normal. In general, the P3 fish showed the least clinical signs of A. hydrophila and normal blood condition, indicating that P3 treatment is best. Conclusion: The best turmeric dosage to improve the immunity of C. batrachus toward A. hydrophila infection is 0.9 g/Kg pellets.

“…In our previous study, a dietary mixture of LP20 and β-glucan enhanced the growth performance, hematobiochemical indices, and immune response of Nile tilapia. Concurrently, Nile tilapia treated with a mixture of LP20 and β-glucan displayed high resistance against DMT toxicity [30]. Nevertheless, the present study tested the influence of the dietary LP20 and β-glucan mixture on the histopathological features, antioxidant status, and anti-inflammation induced by DMT in Nile tilapia.…”

“…Yeast cell-derived substances, such as β-glucan, were also demonstrated as functional immunostimulants when included in aquafeed [29]. The mixture of LP20 and β-glucan was investigated in several studies and approved as an active immunobiotic in aquaculture [30][31][32][33]. In our previous study, a dietary mixture of LP20 and β-glucan enhanced the growth performance, hematobiochemical indices, and immune response of Nile tilapia.…”

The optimal water temperature for the normal growth of Nile tilapia is between 26 and 28 °C, and the toxicity of pesticides is strongly related to water temperature. An alternate approach to augmenting the resistance of fish to ambient water toxicity and low water temperature via synbiotic feeding was proposed. In this study, fish were allocated into four groups with 10 fish in each replicate, where they were fed a basal diet or synbiotics (550 mg/kg) and kept at a suboptimal water temperature (21 ± 2 °C). The prepared diets were fed to Nile tilapia for 30 days with or without deltamethrin (DMT) ambient exposure (15 μg/L). The groups were named control (basal diet without DMT toxicity), DMT (basal diet with DMT toxicity), synbiotic (synbiotics without DMT toxicity), and DMT + synbiotic (synbiotics with DMT toxicity). The results displayed upregulated transcription of catalase, glutathione peroxidase, and interferon (IFN-γ) genes caused by DMT exposure and synbiotic feeding when compared with the controls. Moreover, HSP70 and CASP3 genes displayed increased transcription caused by DMT exposure without synbiotic feeding. However, fish fed with synbiotics showed downregulated HSP70 and CASP3 gene expressions. The transcription of IL-1β and IL-8 genes were also decreased by DMT exposure, while fish fed synbiotics showed upregulated levels. DMT exposure resulted in irregular histopathological features in gills, intestine, spleen, and liver tissues, while fish fed synbiotics showed regular, normal, and protected histopathological images. Our results indicated that dietary synbiotics ameliorated histopathological damages in DMT-exposed tilapia through alleviation of oxidative stress and inflammation as well as enhancing the immunity.
