The Probiotic Lactobacillus sakei Subsp. Sakei and Hawthorn Extract Supplements Improved Growth Performance, Digestive Enzymes, Immunity, and Resistance to the Pesticide Acetamiprid in Common Carp (Cyprinus carpio)

This study evaluated the impacts of the probiotic, Lactobacillus sakei (L. sakei), and the extract of hawthorn, Crataegus elbursensis, on growth and immunity of the common carp exposed to acetamiprid. Fish (mean ± SE: 11.48 ± 0.1 g) feeding was done with formulated diets (T1 (control): no supplementation, T2: 1 × 106 CFU/g LS (Lactobacillus sakei), T3: 1 × 108 CFU/g LS, T4: 0.5% hawthorn extract (HWE), and T5: 1% HWE) for 60 days and then exposed to acetamiprid for 14 days. The growth performance improved in the fish fed LS at dietary level of 1 × 108 CFU/g, even after exposure to acetamiprid (P < 0.05). Intestinal Lactobacillus sakei (CFU/g) load increased (P < 0.05), following supplementation with the probiotic-enriched diet. The LS-treated fish had increases in the activity of digestive enzymes (P < 0.05). Both LS and HWE stimulated antioxidant enzymes and immune system components in serum and mucus (alkaline phosphatase (ALP), protease, total Ig, and lysozyme) (P < 0.05). However, the changes were different depending on the kind of the supplement. The malondialdehyde (MDA) levels decreased in HWE-treated fish after acetamiprid exposure (P < 0.05). Both LS and HWE reduced the liver metabolic enzymes (LDH, ALP, AST, ALT, and LDH) in serum both before and after exposure to the pesticide (P < 0.05). However, each enzyme exhibited a different change trend depending on the type of the supplement. HWE showed a stress-ameliorating effect, as glucose and cortisol levels declined in the HWE-treated fish (P < 0.05). This study indicated the immunomodulatory impacts of LS (1 × 108 CFU/g) and HWE (at dietary levels of 0.5–1%). The probiotic showed more performance compared to HWE. However, the HWE mitigated oxidative stress more efficiently than the probiotic.


Introduction
Today, the development of agriculture has been with widespread use of pesticides (PCs) to control pests [1]. PCs enter aquatic ecosystems through various ways, including field drainage and runoff from land, and adversely affect aquatic life including fish [2]. Since the use of PCs is an unavoidable issue, we must look for solutions to minimize the harmful impacts of these chemicals on aquatic organisms. Probiotics are applied in fish culture as dietary supplements for various purposes. It is a real fact that probiotics improve growth, digestibility, immune system, and resistance to diseases in fish [3][4][5]. Furthermore, it is reported that probiotics may be useful in ameliorating the toxicity induced by PCs [6][7][8]. However, this role is rarely studied in fish [9].
In addition to probiotics, herbal supplements and their compounds are known to enhance fish immunity [10][11][12] and reduce the toxic effects of PCs ( [13,14] [15,16]). However, these studies are few and we need to develop our knowledge about herbs and their role as toxin-ameliorating agent in fish. The immune and antioxidant-stimulating properties of medicinal herbs mainly return to a group of compounds such as flavonoids, carotenoids, alkaloids, tannins, lectins, terpenoids, and polyphenols in their biochemical composition [17][18][19].
The hawthorn is a species of the family Rosaceae that is used in traditional medicine for a long time [20]. In traditional medicine, hawthorn is used to treat digestive disruptions, blood stasis, hypertension, hyperlipidemia, amenorrhea, insomnia, arthritis, and muscle pains [21]. In addition, many studies have reported a variety of functions for hawthorn including antimicrobial, antioxidant, anti-inflammatory, and liver protective activities [22][23][24]. The biochemical composition of hawthorn fruit includes various phytochemicals such as phenolic acids, flavonoids, proanthocyanins, essential oils, and aromatic amines [23]. In fish, a few studies have used hawthorn in diet to improve the cellular and humoral immunity. In challenge with Vibrio harveyi, better immunity is obtained in hawthorn-treated golden pompano, Trachinotus ovatus [21]. Hawthorn, Crataegus mexicana, improved antioxidant and immune system in Longfin yellowtail and Seriola rivoliana [25]. Literatures have showed no study about protective effects of hawthorn against pesticides. Acetamiprid is a neonicotinoid insecticide, which is widely applied in agriculture for control of pests throughout the world [26,27]. The aim of the present study was to examine the potentials of the hawthorn extract and the probiotic bacteria Lactobacillus sakei on growth performance, immune and antioxidant potentials, and resistance to acetamiprid toxicity in the common carp, Cyprinus carpio.

Probiotic Preparations.
The probiotic Lactobacillus sakei subsp. sakei 15521 was prepared from the Iranian Research Organization for Science and Technology in Tehran, Iran, as lyophilized form and incubated in Rogosa and Sharpe agar (MRS) culture medium at 38°C for 48 h. Then, the medium was centrifuged for at 4°C ( × 4000g) 4 min and the supernatant discarded. The pellets were washed three times using phosphate buffer, bacteria added to the phosphate buffer again, and the experimental concentrations were determined at 600 nm by a spectrophotometer. Finally, the experimental concentrations of bacteria were added to the basic food [28].

Hawthorn
Extract. The fruits of hawthorn were provided from Shast Kalate forest, Gorgan, Iran. The fruits were dried at 40°C in an oven. 200 g of dried hawthorn powder was added to 80% ethanol and stirred in an incubator with shaking for 24 h. After that, the suspended particles were removed using Whatman No. 1 paper. The extract was concentrated by a rotary evaporator at 40°C, pulverized by freeze drying, and stored at −18°C until use.

Antioxidant
Power of the Extract. The antioxidant power of the extract was evaluated by four methods as follows and the results presented in Table 1. 2.3.1. Antioxidant Activity by Free Radical Scavenging (DPPH) Method. 100 μl of the extract was mixed with 0.2 ml of 0.1 M 2,2-diphenyl-1-picrylhydrazyl (DPPH) in 150 μM methanol, incubated at 22°C for 35 min, and then its absorbance read at 520 nm. Antioxidant activity was finally calculated using the following formula [29]:

Total Flavonoid
Assay. The total flavonoid content of the hawthorn extract was assayed at 510 nm using aluminum chloride method [31]. A mixture of 250 μl of the extract, 1250 μl of distilled water, and 75 μl of sodium nitrate solution (5%) was prepared, and then, aluminum chloride (10%) was added upon 5 min incubation at 23°C. After incubation, a solution of sodium hydroxide (500 μl) and distilled water (775 μl) was prepared and added to the solution and homogenized, and the adsorption spectrum was read.

Experimental Diets.
To prepare experimental diets, firstly a commercial feed (protein: 34%, fat: 6%, fiber: 5%, moisture: 8%, ash: 9%, and phosphorus: 1%) was purchased as basal diet from Faradaneh company, Iran, which did not contain any supplements. The basal diet was thoroughly ground, mixed with some water to make dough, pelleted by grinder, and dried at 35°C. The experimental diets were prepared by adding Lactobacillus sakei at concentrations 1 × 10 6 and 1 × 10 8 CFU/g feed and hawthorn extract at levels of 0.5 and 1% according to Tan et al. [21]. Doses were selected based on positive results from previous reports on the growth and health of other aquatic animals [21,33,34].
2.6. Acetamiprid and Exposure Trial. Before exposure test, the lethal and acute dosages of acetamiprid for the fish were determined to select experimental concentrations. To estimate lethal range of acetamiprid, fish (n = 30, 10/tank) were exposed to dosages of 0, 6, 8, 10, 12, 14, 16, and 18 mg/l of acetamiprid for 96 h to estimate the LC 50 [36]. The mortality of the fish was recorded upon exposure with time at 24, 48, 72, and 96 h. The probit statistical analysis was used to estimate the lethal concentrations (Table 2) inducing 10% (LC 10 ), 30% (LC 30 ), 50% (LC 50 ), and 70% (LC 70 ) mortality. After feeding period, fish were exposed to acetamiprid at a concentration of 25% of LC 50 for 14 days [16]. The static renewal design was used with the daily water change of 70%.
2.7. Growth Indices. After the feeding experiment, feeding was stopped for 24 h and fish were anesthetized using 100 mg/l eugenol. Growth and nutrition indices were calculated by sampling all fish per tank using the following formulas [35]: where Fiw is the final weight and Iwi is the initial weight.
2.8. Sampling. The blood and mucus samples were taken after feeding period and after 14 days of exposure to acetamiprid.
2.9. Digestive Enzyme Activity. To determine digestive enzyme activities, fish (n = 3/tank) were randomly sampled, euthanized using high dosage of eugenol, dissected, and after the intestine tissue separated. The intestine was emptied and  [37]. The supernatant was obtained by centrifugation at 4°C ( × 6000g for 10 min) and stored at −80°C. Amylase was estimated at 600 nm upon reaction of the enzyme with 2% starch as substrate [38]. Lipase was assayed at 405 nm upon the action of the enzyme on polyphenol myristate, as target [39]. Protease enzyme was measured at 440 nm by García-Carreño [40] method. Azo-casein was used as target for the enzyme.

Intestinal Microbial Population.
After disinfecting of the skin by 70% ethanol, the fish abdominal cavity was dissected and the intestine separated, washed, and homogenized in phosphate buffer (PBS, pH = 7:2) using a tissue homogenizer. The homogenized solution was diluted in phosphate buffer. The bacterial colonies were grown on MRS (Merck, Germany) and TSA medium at 30°C for 48 h to assay lactic acid bacteria (LAB) and total intestinal bacteria (TBC), respectively [41].

Immunological Assays.
To determine immune parameters of serum, fish (n = 3/tank) were anesthetized by eugenol (90 mg/l), and blood was taken from caudal vein using a 1.5 ml syringe, stored in heparinized tube, left at 23°C for 90 min h, and centrifuged at 4°C (3500 × g, 8 min) to collect serum. The serum was stored at −75°C for further assays. Mucus sampling was done by putting fish in polyethylene bags containing saline solution. The supernatant was separated after 3 min through centrifuging of the mucus at 4°C (2650 × g for 12 min) [42].
Serum and mucosal lysozyme activity was measured at 550 nm according to Mirghaed et al. [43] method based on the ability of serum or mucus in lysis of Micrococcus luteus.
Complement activity was measured using sheep red blood cells [44]. 500 μl of serum sample was diluted sequentially (pH = 7) using veronal buffer (EGTA + gelatin + magnesium, pH = 7). 200 μl of red blood cell suspension was added to each tube. The tubes were incubated for 15 min at 15°C. Hemolysis was stopped by adding 10 mmol gelatin veronal buffer−EDTA. After centrifugation, the amount of hemolysis was measured in supernatant at 414 nm.
Total Ig content was calculated based on Siwicki [45] method through calculating the difference between protein content of serum and mucus before and after precipitating by 12% polyethylene glycol. The activity of myeloperoxidase (MPO) was estimated at 450 nm by a microplate reader upon reaction of the enzyme with tetramethylbenzidine hydrochloride as target [46]. Nitroblue tetrazolium (NBT) reduction was assayed at 540 nm upon reaction of the samples with N,N-dimethylformamide [47]. The protease activity was assayed at 450 nm upon reaction of the enzyme with azo-casein (100 mM) as target at 30°C for 20 h [48].

Biochemical and Enzymatic
Assays. The antioxidant potentials were evaluated by estimating glutathione peroxidase (GPx), catalase (CAT), and superoxide dismutase (SOD) using assay kits (Zellbio, Berlin, Germany) and manufacturers' instructions. SOD was assayed upon reduction of cytochrome C [49]. CAT was estimated upon decomposition rate of hydrogen peroxide [50]. Malondialdehyde (MDA) as an indicator of lipid peroxidation was measured based on its reaction with thiobarbituric acid (TBARS) [51].
Liver enzymes were assayed using commercial kits (Pars Azmun Co., Tehran, Iran) for ALP, AST, and ALT according to the manufacturer's protocol [52].
An ELISA method was applied to assay cortisol levels using an assay kit (IBL Co., Germany). Glucose changes were also measured by Pars Azmun commercial kit, Iran [52]. Total protein in serum was measured by the Bradford [53] method. Also, the albumin concentration was estimated by colorimetric method using the Nicholson method at 620 nm [54]. Globulin was assayed by calculation of the difference of protein and albumin content in blood. The activity of alkaline phosphatase activity in mucus was measured by the Pars Azmun commercial kit, Iran, at 405 nm according to manufacturer's instructions [55].
2.13. Data Analysis. The data (mean ± SE) was analysed by version 16 of SPSS software. After normality test by the Kolmogorov-Smirnov test, the differences among the means were evaluated by one-way analysis of variance, followed by the comparison of the means by Tukey test.

Protease activity showed significant increases (P < 0:05) in T 5 in comparison with control, while the enzyme activity of control had no differences with other treatments (P > 0:05).
After exposure to acetamiprid, the lysozyme exhibited more activity (P < 0:05) in all treatments than in control.

Blood Biochemicals.
The results of the liver metabolic enzymes are presented in Table 6. Liver metabolic enzymes showed significant changes in serum in the treatments after feeding period (P < 0:05). AST and ALT activities declined in T 5 in comparison with control (P < 0:05). In addition, AST and ALT showed similar activities among all supplemented groups (P > 0:05). ALP activity had no differences among all treatments (P > 0:05). LDH activity decreased (P < 0:05) in T 3 , T 4 , and T 5 in comparison with control and T 2 . The lowest LDH activity (P < 0:05) was related to T 5 .
After exposure to acetamiprid (Table 6), the ALT activity decreased in T 5 in comparison with control (P < 0:05). ALT activity exhibited similar values (P > 0:05) among all supplemented groups. ALP and AST activities decreased in T 3 , T 4 , and T 5 in comparison with control (P < 0:05). The lowest ALP and AST activities were found in T 5 ( Table 6, P < 0:05). There were no differences in ALP and AST activities between control and T 2 (P > 0:05). The LDH activity of all treatments decreased in comparison with control (P < 0:05).

The CAT activity in treated fish showed no changes (P > 0:05) after exposure to acetamiprid.

Discussion
The application of probiotics and herbs has increased in aquaculture to improve fish growth and immunity. We investigated the prompting impacts of the probiotic, Lactobacillus sakei, and a medicinal plant, hawthorn extract (HWE), on growth, immunity, and the toxin resistance  7 Aquaculture Nutrition ability in the common carp. The growth results showed that the probiotic at high dietary level (1 × 10 8 CFU/g) can effectively improve the growth performance (i.e., FW, WG, SGR, and FCR), even after exposure to acetamiprid, as the highest growth efficiency was related 1 × 10 8 CFU/g probiotic. In addition, we observed increases in the intestinal load of lactic acid bacteria in the probiotic-supplemented fish in comparison with control, indicating the efficient modulation of intestinal bacterial flora by the dietary probiotic. By contrast, such effects were not observed in fish fed HWE (i.e., T 4 : 0.5% HWE and T 5 : 1% HWE). Therefore, these results indicate that the probiotic has more improving effect on growth compared to the plant extract. The enhancing effect of L. sakei on growth may return to the general role of probiotics in improving digestion and absorption of the nutrients, digestive enzyme activities, and production of growthstimulant metabolites and in excluding the pathogenic bacteria in the gut, as previously shown in many researches [56,57]. In this regard, we observed elevations in the activity of amylase and protease in response to dietary L. sakei. As the results showed, the use of the probiotic improved growth indices, even after exposure of the fish to acetamiprid. Although the role of probiotics in reducing the pesticide toxicity has been experimentally reported [6,7,58,59], it is rarely studied in fish [9,60]. The probiotic bacteria may break down pesticides over bioremediation process using the enzymes including phosphotriesterases, phosphatases, carboxylesterases, and organophosphate hydrolases to meet their needs to nitrogen, carbon, and energy [61,62]. In addition, fermentation is another process that probiotic bacteria  Figure 1: The mucus immune parameters in common carp, Cyprinus carpio, after 60 days of supplementation with experimental diets: T 1 (control): nonsupplemented fish; T 2 : fish fed diet containing 1 × 10 6 probiotic; T 3 : fish fed diet containing 1 × 10 8 probiotic; T 4 : fish fed diet containing 0.5% hawthorn extract; T 5 : fish fed diet containing 1% hawthorn extract.

Aquaculture Nutrition may use to metabolize pesticides [6]. Similarly, a combination of the probiotics (Bacillus subtilis + Lactococcus lactis and L. lactis + Saccharomyces cerevisiae) in diet of Indian carp Labeo rohita mitigated the retarded growth in fenvalerate-exposed fish, which was related to the prompting effects of the probiotic on food consumption [60]. In Java   9 Aquaculture Nutrition barb, Barbonymus gonionotus, the use of Lactobacillus spp. in diet reasonably restored the reduced growth in fish exposed to the pesticide Sumithion [9].
Many researches have shown the role of probiotics and herbs in improving the fish immune system [63][64][65][66]. The immune-stimulating properties of Lactobacillus sakei is also reported in fish [33,34,67]. The results of this study confirmed this immunogenic role, because we observed increases in immune components and also antioxidant enzymes in the supplemented fish; however, the change trends were different depending on the kind of the supplement. In this regard, fish fed diet containing 1 × 10 8 probiotic and 0.5 and 1% hawthorn extract showed higher values of antioxidant and immune components in almost all treatments both before and after exposure to acetamiprid. However, hawthorn treatments seem to be more effective in improving the immune and antioxidant system than the probiotic treatments. Although the stimulating properties of probiotics on fish immunity are widely reported, there is little data about this function with pesticides [68]. Probiotics improve the immune system in a variety of ways, such as modulating of intestinal bacterial flora, competing with and eliminating pathogenic bacteria in the gut, stimulating the activity of innate immune system components such as lysozyme, complement, and immunoglobulin, and upregulation of immune-related gene expressions [65,[69][70][71]. Also, as mentioned earlier, probiotics can biodegradate and fermentate the pesticides in the gastrointestinal tract, which may reduce their immunotoxic impacts [6,61,62]. Although the role of probiotics as antioxidants and also their inducing effect on enzymatic antioxidant enzyme system are reported, its mechanism is still unknown. Antioxidant function of probiotics in fish is attributed to their prompting impacts on modulation of antioxidant genes. For example, in the gilthead seabream Sparus aurata, the expression of SOD and GPx in the mucus is upregulated in Shewanella putrefaciens-and Bacillus-treated fish [72]. Similarly, the SOD and GPx values were stimulated in response to dietary B. licheniformis in O. mossambicus [73]. In Indian carp, Labeo rohita, the diet containing Bacillus subtilis + Lactococcus lactis and L. lactis + Saccharomyces cerevisiae mitigated the toxic effects of the insecticide fenvalerate. In their study, the probioticcontaining diets had sparing effects on SOD and CAT activities. In addition, the probiotic improved NBT, total protein, and albumin values in blood of fenvalerate-exposed fish [60].
There were many studies reporting increases in MDA levels as the main marker of oxidative stress, following exposure to pesticides in fish [74,75]. MDA levels declined in hawthorn extract-supplemented fish, which may suggest an ameliorating effect for the supplement on the oxidative stress. The mitigating role of medicinal plants on pesticideinduced oxidative stress has been also reported in other studies, which is usually attributed to their stimulating effects on antioxidant enzymes and the presence of some compounds such as phenolic compounds and flavonoids in their biochemical composition [16,76,77].
In blood, increased concentration of hepatic enzymes (ME) may indirectly reflect liver dysfunctions and damages, although ME are not generally specific [78]. The use of the probiotic and hawthorn reduced LME levels both before and after exposure to the pesticide. However, each enzyme showed different change trends depending on the type of the supplement. Decreased levels of LME may demonstrate a protective effect for the supplements on the liver [79]. In this regard, it seems that the use of 1% hawthorn has more performance than other supplements, because LME decreased in this treatment. Similarly, the reducing effects of probiotics [80] and herbs [77,81,82] on LME are previously reported in pesticide-treated fish.
As the main stress hormone, cortisol is released in blood after exposure to variety of stressors. Cortisol breaks down hepatic glycogen stores to release glucose into the bloodstream to meet energetic costs of the stress [83,84]. In this study, hawthorn extract showed a stress-ameliorating effect, because cortisol and glucose levels reduced in HWE-treated fish both before and after exposure to pesticide. Pesticideinduced stress in fish and following increases in cortisol and glucose have been reported in many studies [85][86][87]. The current results were in line with previous studies that have reported the mitigating effect of herbs on stress caused by pesticides [13,16,88,89]. In probiotic treatments, the cortisol levels decreased only in the treatment 1 × 10 8 CFC/ g probiotic after exposure to the pesticide, which may return to the mitigating impacts of probiotics on stress [90,91]. In this study, although fish growth and immunity improved in the supplemented fish, the survival rate was not affected over exposure to the pesticide.
The outputs of this study revealed the immunomodulatory properties of LS (at dietary levels of 1 × 10 8 CFU/g) and HWE (at dietary levels of 0.5-1%) in the common carp. The probiotic exhibited more growth-prompting effect compared to HWE. However, the HWE mitigated oxidative stress more efficiently compared to the probiotic.
