“…In a recent study, curcumin could modulate the immunological capacity of Pacific white shrimp fed contaminated toxin diet (Yu et al, 2018). Moreover, diets supplemented with green tea extract amplified the humoral and mucosal immunity response, improved growth performance and presented higher challenge against S. agalactiae infection in Nile tilapia (Van Doan et al, 2019). Thus, it could be investigated that some feed additives that contain polyphenol and phytogenic active compounds could be useful as immunomodulatory factors against pesticides harmful effects on farmed fish.…”

Intensive fish culturing systems depend on provides optimal water quality conditions. Hence, the most important aquaculture practices are the removal of contamination elements related not only to the water quality parameters unacceptable for aquatic species but also to the undesirable effect on the health of fish and consumers. During the last three decades, common applications and production of pesticides have amplified progressively. Due to the excessive use of imidacloprid as a highly effective insecticide, elevated accumulation is expected in an aquatic environment. A large part of applied pesticides emitted into the environment and only a small portion of them reach the final biological target, where it caused several hazards, such as accumulation and toxicity to non‐target creatures. Plant‐derived secondary metabolites are getting great attention due to their safety and therapeutic functions. Also, several feed additives in animal diets can act as chemopreventive agents, which have the potential to decrease the toxicity risk of many pollutants and detoxification of activated metabolites. Understanding the internal action mechanisms of various safe feed additives could lead to the novel therapeutic approaches for acute and chronic pesticide toxicity. This review intends to summarize how safe feed additives alter or mitigate the toxic effects of imidacloprid in farmed fish.

The main purpose of this study was to consider the impact of Vitex agnus-castus hydroalcoholic extract, containing phytoestrogenic compounds on growth indices, sex ratio and histology of gonads of female Zebrafish. Fish larvae (4-day-old after hatching) were nourished with investigational diets (0 (control group T0), 5 g (T1), 10 g (T2) and 15 g (T3) kg−1 food) from first active feeding for 90 days. The results showed that Condition Factor (CF), Food Conversion Rate (FCR), Body Weight Gain (BWG), and Specific Growth Rate (SGR) were affected meaningfully by hydroalcoholic extract of Vitex agnus-castus (p < 0.05). These factors were significantly higher in compare to T3 treatment (p < 0.05). With increasing concentration of the extract in the diet, the ratio of female to male increased Treatment of T3 resulted in 87.23% feminization. Overall, this study suggests the use of T3 treatment achieves the best reproduction performance and a higher percentage of females in zebrafish as a model for aquaculture species. According to the results, the lowest levels of glucose and cholesterol were observed in T3 treatment and showed a significant changes with the control and treatments (p < 0.05).

“…These additives could augment the growth of beneficial microbial colonies in the digestive tract, which leads to enhance feed intake and weight gain of various aquatic species (Safari et al, 2017). Increased resistance against infectious diseases of aquatic species following the administration of different medicinal plants was also shown previously (Van Doan et al, 2019b;Van Doan et al, 2019c;Yin et al, 2008).…”

“…Medicinal plants have widely attracted the aquaculture researchers because of their beneficial influence on fish such as improving the innate immune responses, improving growth, and feed digestibility (Adel et al, 2016b;Mahmoud et al, 2019;Van Doan et al, 2019b;Van Doan et al, 2019c). These additives could augment the growth of beneficial microbial colonies in the digestive tract, which leads to enhance feed intake and weight gain of various aquatic species (Safari et al, 2017).…”

This study evaluated the effects of grape seed extract (GSE) on the growth performance, immune response, and disease resistance of common carp (Cyprinus carpio). Fish were distributed in four groups and fed diets with varying levels of GSE at 0, 10, 20, and 30 g/kg for 56 days. The final length in fish fed with 20 and 30 g GSE/kg diet significantly increased in comparison with the control group (P<0.05). The final weight and weight gain of fish fed with GSE were statistically higher than the control diet, while the feed conversion ratio was lower in GSE groups than the control. Hematological parameters did not statistically enhance with GSE supplemented diets (P>0.05). However, fish fed with 30 g GSE/kg diet displayed a higher WBC count significantly than the other group (P<0.05). The serum total protein and globulin in fish fed with 20 g GSE/kg diet significantly increased compared to the control (P<0.05). A similar pattern was noticed in results for serum and mucus lysozyme activity with a significant increase in fish fed with 20 and 30 g GSE/kg diet compared to the control (P<0.05). Total antibody levels in serum and mucus samples were also increased in fish by dietary GSE with maximum levels by 20 and 30 g GSE/kg diet. Besides, mucus protease activity was higher in fish received 20 and 30 g GSE/kg diet with maximum level shown in fish fed with 30 g GSE/kg diet compared to the control group (P<0.05). Meanwhile, all groups showed higher mucus antibacterial activity against Aeromonas hydrophila with the highest activity in 30 g GSE/kg diet in comparison with the control group. The cumulative mortality was 36.67% when fish fed with 30 g GSE/kg diet and challenged with A. hydrophila. However, the mortality rate was 40% and 53.33% in fish fed 20 and 30 g GSE/kg diet, respectively. This study suggests that supplementation of GSE could significantly enhance the growth performance, immune responses, and disease resistance against A. hydrophila in common carp.
