The present study investigated the effect of partial substitution of soybean meal (SM) for fish meal (FM) with or without addition of inulin and oligofructose in pikeperch feed. A diet containing FM was considered as the basal diet, and then three other diets were prepared by: 1) replacing 50% of FM with SM (SM50), 2) replacing 50% of FM with SM and supplementation of 2% inulin (SMI50), and 3) replacing 50% of FM with SM and supplementation of 2% oligofructose (SMO50). Each diet was fed twice daily to triplicate groups of fish (36.68 ± 0.36 g) for eight weeks. The group fed SMO50 showed the highest weight gain (WG; 85.85 ± 4.46%) among the groups fed SM, with no significant difference from the FM group (79.74 ± 2.04%; p > 0.05). Specific growth rate (SGR) showed no significant differences among fish fed SMI50 (0.81 ± 0.07%), SMO50 (1.01 ± 0.09%) and FM (1.05 ± 0.02%). However, a lower SGR (0.69 ± 0.09%) was observed in the SM50 group without the supplementation of 2% inulin or oligofructose compared to the group fed FM (p < 0.05). The groups fed SMI50 and SMO50 showed no significant difference in FCR (1.23 ± 0.10; 0.91 ± 0.05, respectively) compared to the group fed FM (0.97 ± 0.04). While, a significant difference in FCR was found between the SM50-fed group without supplementation of inulin or oligofructose (1.50 ± 0.13) and the group fed FM (0.97 ± 0.04). Survival rate and whole-body composition showed no significant difference among all groups (p > 0.05). A significant decrease in serum total cholesterol concentration was observed in the SMO50 group (2.10 ± 0.29 mmole L-1) compared to the FM-fed group (3.33 ± 0.33 mmole L-1). Serum triglyceride showed a significant decrease in the groups fed SMI50 (0.98 ± 0.17 mmole L-1) compared to the group fed SMO50 (1.93 ± 0.24 mmole L-1). The concentrations of other serum biochemical parameters (total protein, glucose, lactate dehydrogenase, alanine aminotransferase, aspartate aminotransferase, and alkaline phosphatase) were not significantly affected by the dietary treatments (p > 0.05). Among all innate immunity and antioxidant parameters, only the serum malondialdehyde (MDA) concentration of SM50-fed fish (4.25 ± 0.7 nmole mL−1) was significantly lower than in the FM-fed group (with the highest MDA concentration; 25.17 ± 3.13 nmole mL−1). Serum total antioxidant capacity (T-AOC), superoxide dismutase (SOD), and catalase (CAT) were not significantly affected by the feeding (p > 0.05). Serum D-lactate concentration was not significantly affected by the dietary treatments (p > 0.05). No significant differences were found in the relative expression of IGF-I, IGF-II, GHR genes among the studied groups (p> 0.05). The results of the present study show that 50% replacement of FM with SM supplemented with a small amount of oligofructose (2% of dry matter) does not compromise the growth performance or the immune system of pikeperch. This substitution is feasible and provides a reference for cost-optimized design of feed formulation for pikeperch.
1 Introduction
Pikeperch, Sander lucioperca (Linnaeus, 1758), is considered a species of great interest for aquaculture due to its rapid growth, high nutritional value of the meat, and high commercial value (Jankowska et al., 2003; Pěnka et al., 2021), with growing interest in intensive culture development in European countries such as Poland, Netherland and Czech Republic (Klein Breteler, 1989; Zakes, 1999; Ostaszewska et al., 2005; Schulz et al., 2006; Hamza et al., 2007; Kestemont et al., 2007; Policar et al., 2019; Imentai et al., 2022). The pikeperch is the most important predator in many aquatic ecosystems and is valued for its ability to drive unwanted fish species out of water bodies (Adámek and Opacak, 2005; Specziár, 2011). Pikeperch predation is concentrated on the species most abundant in the local community (Lappalainen et al., 2006), and cyprinids are a common stomach content (Peltonen et al., 1996).
To meet the protein requirement for adequate growth rate and feed conversion of pikeperch, at least 43% protein is required (Nyina-Wamwiza et al., 2005). This protein requirement has traditionally been met with fishmeal (FM) (Tacon and Metian, 2008) which is an excellent source of protein due to the essential amino acids, minerals, and nucleotides required for commercial production of carnivorous fish (Oliva-Teles et al., 2015). Increasing demand and competition with other users, dwindling supply, and high price have encouraged the search for more sustainable alternative ingredients to partially or fully replace FM (Lunger et al., 2007; Peng et al., 2013). In this regard, a wide range of protein sources have been evaluated to find sustainable alternative ingredients as the main protein source of plant origin (including soybeans, wheat, peas, grains or oilseeds) and animal origin (poultry meal, blood meal, feather meal) (Gatlin et al., 2007; Li et al., 2011; Badillo-Zapata et al., 2014; Pares-Sierra et al., 2014; Tangendjaja, 2015; Wang et al., 2017; Tran et al., 2019; Ye et al., 2019; Li et al., 2020).
Among all plant-based candidates, soybean meal (SM) has been suggested as one of the most promising alternatives to replace FM due to its comparatively balanced amino acid profile, high digestibility, reasonable price, sustainable supply chain, and good availability (Wang et al., 2006; Gatlin et al., 2007; Imorou Toko et al., 2008; Yue and Zhou, 2008; Lin and Luo, 2011).
Despite considerable success in partially or completely replacing fishmeal with soybean meal in fish feed (Al-Kenawy et al., 2008; Ajani et al., 2016; Rahimnejad et al., 2021; Badillo-Zapata et al., 2021), the problems with palatability, digestion, nutrient utilization, and antinutritional factors (ANFs) such as β-conglycinin, protease inhibitors, and oligosaccharides continue to limit the substitution of SM for FM in carnivorous fish diets (Mambrini et al., 1999; Papatryphon and Soares, 2001; Peres et al., 2003; Zhou et al., 2005). It is well established that high levels of SM in the diet of carnivorous fish often have negative impacts on growth rate, protein and lipid metabolism, and health status (Refstie et al., 1998; Mambrini et al., 1999; Chou et al., 2004; Tomas et al., 2005; Zhou et al., 2005; Choi et al., 2020). In addition, the inclusion of SM in fish diets can impair immune function and lead to characteristic features of intestinal inflammation and/or lesions, and abnormal vacuolization (Baeverfjord and Krogdahl, 1996; Burrells et al., 1999; Hedrera et al., 2013; Wang et al., 2016; Kokou et al., 2017).
Prebiotics are non-digestible carbohydrates that are used as dietary supplements to mitigate the effects of various anti-nutritional factors and reduce the adverse effects of replacement diets, such as diets formulated with SM (Li and Gatlin, 2004; Li and Gatlin, 2005; Burr et al., 2008). In addition, they positively affect innate immune responses via modification of the gastrointestinal microbial community (López Nadal et al., 2020), improve oxidative status by reducing oxidative damage or increasing antioxidant potential (Zhang et al., 2013; Zhang et al., 2014; Guerreiro et al., 2015), increase mineral absorption (Bongers and van den Heuvel, 2003), and improve growth rate and feed conversion (Pattipeiluhu et al., 2020).
According to previous studies, inulin and oligofructose are among the most widely used prebiotics as feed ingredients worldwide (Van Loo et al., 1999; Ringø et al., 2010). Undoubtedly, these prebiotics possess several functional and nutritional properties (Such as: fiber enrichment, reduction of serum triglycerides and blood cholesterol, bifidogenic effect, and short-chain oligomers and high solubility) that are beneficial in feed formulation (Niness, 1999) and may have a positive impact on the health status and the immune system (Watzl et al., 2005; Cerezuela et al., 2008), growth rates and/or survival (Samrongpan et al., 2008; Hoseinifar et al., 2011b), blood profiles (Hoseinifar et al., 2011a), and gastrointestinal microbiota (Ringø et al., 2006; Bakke-McKellep et al., 2007) of aquatic animals, including various fish species.
Despite the availability of some commercial aquafeeds for percids, which are mostly salmonid-targeted feeds (Stejskal et al., 2016), attention has been drawn to the inadequate formulation of specific feeds for percid fishes. In order to develop sustainable feeds for these species, their nutritional needs must be considered (Bochert, 2020). Therefore, in this study we investigated the effect of fish meal substitution by soybean meal (50%), with or without the addition of inulin and oligofructose, on growth, immune parameters, and expression of growth-related genes in pikeperch.
2Materials and methods
2.1 Experimental design and diet preparation
The formulation and composition of the diets are shown in Table 1. The prebiotics inulin (with >90% purity) and oligofructose (with >95% purity) were sourced from BENEO GmbH, Germany. A basal diet was formulated using FM (45% crude protein and 12% crude lipid). Three other diets were prepared by replacing 50% of FM with SM (SM50) and supplementation of 2% inulin or oligofructose to the SM50 diet by replacing wheat flour in the diet (SMI50 and SMO50, respectively). Fish meal and soy protein concentrate were used as the main protein sources, and a mixture of fish oil and soybean oil was used as fat sources. The ingredients were properly formulated with a well-balanced energy-to-protein ratio to keep the dry matter content of each diet at 100%. For diet preparation, the ingredients were weighed on a precision scale and then thoroughly mixed in a blender (400V HTS42 2T, RM Gastro, EU) and homogenized with the appropriate amount of water. The prepared mixture was pelletized (1.5 and 2.5 mm) using a multifunctional spiral extrusion machine (P 98 CE, BRAHER INTERNACIONAL, Spain). The pellets were dried overnight at 35°C, sealed in bags and stored at 4°C until use.
2.2 Fish and feeding trial
The feeding experiment was conducted in an experimental recirculating aquaculture system (RAS) under controlled conditions at the Faculty of Fisheries and Protection of Waters, University of South Bohemia (FFWP, USB) (Vodnany, Czech Republic). The experimental facility was equipped with twelve round tanks (150 l) with a BaseDrum 15 mechanical dram filter (Ratz Ltd, Remscheid, Germany) and a 2000 l mobile biological filter (Ekory Ltd, Jihlava, Czech Republic) and a C-0 oxygen cone (Aquacultur Fischtechnik Ltd, Nienburg, Germany). Water in the tanks was supplied at a constant flow rate of 2.5 L min-1 to change tank volume every 30 min. Seventy randomly intensive cultured pikeperch (36.68 ± 0.36 g) according to Policar et al. (2016) were distributed to each tank and fed with a commercial feed (Inicio Plus, BioMar, 3 mm) for two weeks to acclimate them to the experimental conditions. At the end of the acclimation period, four prepared experimental diets were fed to triplicate four groups twice daily (07:00 and 15:00) for 8 weeks until satiation. Feeding was stopped 24 h before weighing or blood sampling to minimize handling stress. Rearing water temperature, pH, and dissolved oxygen (DO), nitrite (NO2-), and ammonium nitrogen (NH4+-N) concentrations were maintained at 21.1 ± 0.3°C, 7.19 ± 0.06, 98.08 ± 0.64%, 0.41 ± 0.08 mg L-1, and 0.78 ± 0.29 mg L-1, respectively. The photoperiod was maintained with a 12:12 light/dark cycle.
2.3 Sample collection
At the end of 8 weeks feeding experiment, all fish were weighed individually for calculation of growth parameters, feed utilization and survival rate. Five intact fish from each tank were randomly sampled and stored at -20°C for analysis of proximate composition. Ten fish per tank were randomly captured, anesthetized (clove oil, 0.3 ml 10 l-1 water), and blood samples were collected from the caudal vein using non-heparinized syringes and allowed to clot at 4°C for 24 h. The collected blood serum was separated by centrifugation at 5,000 × g for 10 minutes and stored at -80°C for subsequent analysis of blood biochemical values, innate immunity, antioxidant parameters, and D-lactate concentration.
2.4 Whole-body composition
Whole-body composition analysis was conducted according to the standard procedures (Association of Official Analytical Chemists (AOAC), 2005). Moisture was measured by drying in a NÜVE type FN 400P oven (NÜVE, Ankara, Turkey) at 105°C to constant weight (Adineh et al., 2020). Crude protein was analyzed using the Kjeldahl method (BUCHI Labortechnik AG, type K-360, Königswinter, Germany) (Zaefarian et al., 2017). Crude lipid was determined using the extraction method of Hara and Radin (1987) with slight modifications (Zajic et al., 2013). Ash content was analyzed in a muffle furnace L 40/11 BO (Nabertherm GmbH, Lilienthal, Germany) at 550°C for 4 h (Zaefarian et al., 2017).
2.5 Blood biochemistry, immunity, and antioxidant activity
Kits using a VET-TEST 8008 analyzer (IDEXX Laboratories Inc, Maine, United States) were used to measure serum biochemical indices, including total protein (TP), triglycerides (TG), total cholesterol (CHO), glucose (GLU), alanine aminotransferase (ALT), aspartate aminotransferase (AST), alkaline phosphatase (ALP), and lactate dehydrogenase (LDH). Catalase (CAT) and superoxide dismutase (SOD) activities were determined spectrophotometrically using commercially available assay kits (ThermoFisher Scientific, CA, USA, and Sigma, 19160, respectively). Malondialdehyde (MDA) concentration was measured spectrophotometrically using commercial assay kits (Sigma-Aldrich, Missouri, USA). Lysozyme activity of the samples was measured by a turbidimetric method (Parry, 1965). Briefly, 10 µL of serum diluted 1:2 with 10 mM PBS, pH 6.2, was placed in a 96-well flat-bottomed plate. To each well, 200 µL of freeze-dried Micrococcus lysodeikticus in the above buffer (0.3 mg mL-1, Sigma) was added as a lysozyme substrate. The decrease in absorbance at 450 nm was measured over 15 min at 3 min intervals at room temperature in a plate reader. One unit of lysozyme activity was defined as an absorbance reduction of 0.001 min-1. The units of lysozyme present in serum were determined using a standard curve constructed with hen egg white lysozyme (HEWL, Sigma), and the results were expressed as units mL -1. Peroxidase activity was determined according to Quade and Roth (1997). Five µL of serum was diluted with Hanks’s buffer (HBSS) without Ca+2 or Mg+2 to a final volume of 50 µL in a flat-bottomed 96-well plate. As substrate, 100 µL of 10 mM TMB containing 0.025% of 30% H2O2 was added, and the color change reaction was stopped by adding 50 µL 2 M H2SO4. Optical density (OD) was read at 450 nm in a plate reader. Sample without serum were used as blank, and its OD value was subtracted for each sample value. One unit was defined as the amount that produced an absorbance change of 1, and the activity was expressed as units mL -1 in each sample. Total immunoglobulins (Igs) content was determined according to the method described by Siwicki and Anderson (1993). Briefly, an aliquot (0.1 mL) of each serum sample was mixed with an equal volume of a 12.0% PEG solution (polyethylene glycol, Sigma) and incubated at room temperature for 120 min and centrifuged at 5000 × g for 5 min at 4°C to precipitate immunoglobulin. The supernatant was diluted 30 times with 0.85% NaCl, and the protein content was determined by the Bradford method. The difference between the protein values of the untreated and PEG treated samples was determined as the total Igs content and expressed as mg mL -1.
2.6 Serum D-lactate concentration
Serum D-lactate concentration was determined using a commercially available kit (D-lactate colorimetric assay; Sigma-Aldrich). Absorbance at 450 nm was measured with a Wallac Victor 3 Multi-well Plate Reader (Perkin Elmer).
2.7 Gene expression
2.7.1 RNA extraction and reverse transcription
To extract total RNA, liver samples were collected from RNAlater and then the RNeasy Mini-Kit (QIAGEN, Germany) was used according to the manufacturer’s protocol. The extraction protocol included on-column treatment with DNase I (Qiagen). RNA concentration was measured spectrophotometrically using NanoDrop 2000 (Thermo Fisher Scientific, Germany) and RNA purity was assessed by 260/280 and 230/280 ratios. Reverse transcription was performed with total RNA as follows: 1 μg of total RNA was first incubated with an oligo (dT) primer (sequence: 5′−CCTGAATTCTAG AGCTCA(T)17-3′) in a 20 μL reaction at 70°C for 5 min and then cooled on ice. After addition of dNTPs (New England BioLabs Inc.), 200 U RevertAid Reverse Transcriptase (ThermoFisher Scientific, Germany), and the reaction buffer supplied with the enzyme, the resulting 30-μL reaction was heated at 42°C for 60 min and at 70°C for 15 min. A RT control, in which RevertAid Reverse Transcriptase was replaced with pure water, was added to exclude possible contamination of samples by genomic DNA. cDNA samples were subsequently stored at -20°C.
2.7.2 Relative real-time PCR
Relative real-time PCR assays were performed with gene-specific primers for growth-related genes of pikeperch, including growth hormone receptor (GHR), insulin-like growth factor-I (IGF-I), and insulin-like growth factor-I (IGF-II). Primer sequences are listed in Table 2. Assay reaction volume: 2 μL of 10x diluted cDNA, 7.5 pmol of each primer, and 1× FastStart Universal SYBRGreen Master (Rox) (Roche)] were run in a Mx3005p RT-PCR cycler (Agilent Technologies) as follows: initial denaturation at 95°C for 10 min, followed by 40 cycles of denaturation at 95°C for 17 s, primer annealing at 58, 60, 62, or 65°C for 35 s, and extension at 72°C for 25 s. PCR was performed in duplicate for all samples. The relative values of the target transcript abundance in individual samples were determined by the comparative CT method (ΔΔCT) according to Pfaffl (2001). The mRNA expression of the reference gene (GAPDH; Table 1) was used for normalization. Normalized expression of target genes is expressed as mean ± SEM relative to control.
2.8 Statistical analysis
Before the analysis, the characteristics of the data distribution and the homogeneity of the dispersion were evaluated using the Shapiro-Wilk test and Levene’s test, respectively. Then, data with normal distribution were analyzed using one-way analysis of variance (ANOVA) followed by Tukey’s honest significant difference (HSD) test. Non-homogeneous data were analyzed using a non-parametric Kruskal-Wallis test followed by multiple comparison of the mean ranks of all groups. Statistical significance was assumed at p < 0.05. Data are presented as mean ± SEM. All analyzes were performed with SPSS version 17.0 (SPSS Inc., Chicago, IL, USA).
3 Results
The group fed SMO50 showed the highest weight gain (WG; 85.85 ± 4.46%) among the groups fed SM, with no significant difference compared to the FM group; 79.74 ± 2.04% (p > 0.05; Table 3). Specific growth rate (SGR) showed no significant differences among fish fed SMI50 (0.81 ± 0.07%), SMO50 (1.01 ± 0.09%) and FM (1.05 ± 0.02%; p > 0.05). However, lower SGR (0.69 ± 0.09%) was observed in the SM50 group without supplementation of 2% inulin or oligofructose compared to the group fed FM (p < 0.05; Table 3). Similarly, a significant difference in FCR was observed between the SM50-fed group without supplementation of inulin or oligofructose (1.50 ± 0.13) and the group fed FM (0.97 ± 0.04; Table 3). The groups fed SMI50 (1.23 ± 0.10) and SMO50 (0.91 ± 0.05) showed no significant difference in FCR compared to the group fed FM (0.97 ± 0.04; Table 3). The FCR was significantly lower in the SMO50-fed group (0.91 ± 0.05) compared to the group fed SM50 (1.50 ± 0.13). The survival rate in the four groups ranged from 95.13 to 97.77%, with no significant difference observed among all groups (p > 0.05; Table 3). The proximate composition of whole-body is shown in Table 4 and no significant difference was found among all groups (p > 0.05).

Table 4 Whole-body composition of pikeperch fed the experimental diets for 8 weeks (% dry matter basis).
Replacement of FM with SM resulted in a significant decrease in serum total cholesterol concentration (T- CHO) in the SMO50 group (2.10 ± 0.29 mmole L-1) compared to the FM-fed group (3.33 ± 0.33 mmole L-1; Table 5). There were no significant differences between the other SM-fed groups and the FM-fed group (p > 0.05). Serum triglyceride showed a significant reduction in the groups fed SMI50 (0.98 ± 0.17 mmole L-1) compared to the group fed SMO50 (1.93 ± 0.24 mmole L-1; Table 5). No significant difference was observed in triglycerides between the other groups (p > 0.05; Table 5). The concentrations of other serum biochemical parameters (triglyceride: TG, total protein: TP, glucose: GLU, lactate dehydrogenase: LDH, alanine aminotransferase: ALT, aspartate aminotransferase: AST, and alkaline phosphatase: ALKP) remained unchanged (p > 0.05; Table 5).
Among the parameters of innate immunity and antioxidants, lysozyme activity (LYZ), peroxidase, and total immunoglobulin (T-Ig) showed no significant differences among the studied groups (p > 0.05; Table 6). In contrast, a significant difference was observed in the serum malondialdehyde (MDA) concentration of the group fed FM (25.17 ± 3.13 nmole mL−1; Table 6) compared to the groups fed SM50, SMI50, and SMO50 (ranging from 4.25 to 14.77 nmole mL−1; Table 6). Total antioxidant capacity (T-AOC), superoxide dismutase (SOD) and catalase (CAT) in serum were not significantly affected by the feeding (p > 0.05; Table 6). Serum D-lactate concentration was not significantly affected by the dietary treatments (p > 0.05; Figure 1). The results of gene expression analysis of growth-related genes, IGF-I, IGF-II, and GHR showed no significant difference among the studied groups (P > 0.05; Figure 2).

4 Discussion
Different effects have been reported in various omnivorous and carnivorous fish species due to dietary soybean supplementation (Viola et al., 1982; Shiau et al., 1989; Shiau et al., 1990; Webster et al., 1992; Shimeno et al., 1993; Refstie et al., 2000). Previous studies on carnivorous fish have shown conflicting results on the replacement of FM with SM, including the possibility of replacing FM with only a small amount of SM (Krogdahl et al., 2010; Merrifield et al., 2011) and a large tolerance to the replacement of FM (Webster et al., 1992; Zhang et al., 2018).
In the present study, replacing 50% of FM with SM did not impair the growth performance of pikeperch. This result is consistent with a study in which FM was replaced with up to 100% SM in the diet of an omnivorous fish, Pacific fat sleeper (Dormitator latifrons), and showed adequate growth without effects on body composition and survival (Badillo-Zapata et al., 2021). Replacement of FM up to 70% with crude protein from toasted soybean meal also did not compromise growth of carnivorous blue catfish, Ictalurus furcatus (Webster et al., 1992). Similar to our results, Zhang et al. (2018) reported no significant changes in growth performance of Japanese sea bass, Lateolabrax japonicus, when 50% of FM was replaced with SM. In contrast to these reports, an impaired growth performance was revealed in some carnivorous fish species such as Atlantic salmon, Salmo salar (> 20%; Krogdahl et al., 2003) and cobia Rachycentron canadum (> 40%; Chou et al., 2004) when FM was partially replaced with SM. Among the groups fed SM50, SMI50, and SMO50, the highest weight gain was observed in the group fed SMO50, highlighting the beneficial effect of oligofructose on the growth rate of carnivorous fish (Mahious et al., 2006).
According to the present results, the specific growth rate significantly decreased in the SM50-fed group, and supplementation of the prebiotics (inulin and oligofructose) significantly improved the specific growth rate. In the current study, there was a significant increase in FCR in the SM50-fed group compared to the FM-fed group. While, oligofructose supplementation resulted in significantly lower FCR in the SMO50-fed group (0.91 ± 0.05; close to the FM-fed group) compared to the SM50-fed group (1.50 ± 0.13). A study on Atlantic salmon showed a reduction in feed conversion when 40% of FM was replaced with SM (Refstie et al., 1998). In contrast, no negative effects on growth and FCR were observed in rainbow trout, Oncorhynchus mykiss when 60% of FM was replaced with SM (Barnes et al., 2012). Similarly, an inclusion level of SM up to 40% does not seem to adversely affect growth, feed efficiency, and protein utilization in cobia (Chou et al., 2004). In Carassius auratus gibelio ♀ × Cyprinus carpio ♂, the best growth responses and feed efficiency were obtained with a limited substitution to < 38.52-41.81% and 40.75%, respectively (Liu et al., 2020).
Replacing 50% of FM with SM, either with or without probiotics, did not result in significant changes in whole-body composition in the present study. Consistent with the present results, whole body proximate compositions were not affected when 0, 70, 80, 90, and 100% of fish meal protein was replaced with dehulled soybean meal in red sea bream (Pagrus major) diets (Kader et al., 2012). A previous study on sea bass is consistent with these results (Tibaldi et al., 2006) when fish were fed either a FM-based diet (control) or an isoprotein, isolipid and isocaloric soy replacement diet. The diets consisted of replacement of FM protein with: 25% toasted, dehulled, and solvent-extracted soybean meal; 50% dehulled and toasted soy seeds subjected to dry extrusion and mechanical oil extraction; 50% enzyme-treated soybean meal; and an inclusion of 60% composed of 30% toasted, dehulled, and solvent-extracted soybean meal and 30% enzyme-treated soybean meal.
Hematological indices are commonly used to evaluate the physiological and health status of fish in studies focused on replacing fishmeal with soybean in the diet (Ajani et al., 2016; Rahimnejad et al., 2021; Xu et al., 2022). Despite lowering blood cholesterol levels by replacing animal proteins with soy protein in various animal models (Cho et al., 2007), it has been claimed that a formulated diet containing 45% SM with or without Heat-Killed Lactobacillus plantarum has no effect on total cholesterol level in amberjack, Seriola dumerili (Dawood et al., 2015). Similarly, our results showed no significant change in serum total cholesterol levels when FM was replaced with SM. However, a significant decrease was observed in the oligofructose supplemented group fed SM50 (2.10 ± 0.29), which underlines the probable effect of oligofructose supplementation on cholesterol levels in fish (Hoseinifar et al., 2011a). In agreement with the present study, serum total cholesterol was not significantly decreased when 40% FM was replaced by SM in the diet for Japanese sea bass, Lateolabrax japonicas (Rahimnejad et al., 2019). However, increasing the substitution of SM for FM from 40% to 80% resulted in a decrease in serum total cholesterol in this species (Rahimnejad et al., 2019). Similarly, replacing FM with SM (47.6%) in the diet of rainbow trout lowered plasma cholesterol levels (Yamamoto et al., 2010). The reported reductions could be due to either interruption of intestinal uptake of dietary bile acids and cholesterol (Makino et al., 1988) or enhancement of LDL-R transcription in hepatocytes (Cho et al., 2007). The capacity of the antioxidant system is a key indicator reflecting health status and oxidative stress in fish (Deng et al., 2015). Therefore, the effects of soybean meal on the innate immunity and antioxidant parameters of pikeperch were also investigated. In the present study, there were no statistically significant differences in LYZ, POX, T-Ig and T-AOC. In addition, two representatives of the first line defense antioxidants, SOD and CAT, did not change significantly in the studied groups. However, MDA as one of the most important indicators of lipid peroxidation with a high level of biotoxicity to cells (Parvez and Raisuddin, 2005) significantly increased in the FM-fed group with the highest MDA value (25.17 ± 3.13 nmole ml L−1). The lower MDA value in the groups fed SM50, SMI50, and SMO50 could be attributed to the activity of other first line defense antioxidants such as glutathione peroxidase (GPx) or second line defense antioxidants such as ascorbic acid, uric acid, and glutathione (Ighodaro and Akinloye, 2018). On the other hand, soybeans contain phenolic compounds and flavonoids, of which isoflavones are the most abundant (Liu et al., 2005). The isoflavones have been shown to act as potent antioxidants and may be responsible for preventing lipid peroxidation (Jha et al., 1985).
Serum D-lactate is a well-established marker that indirectly assesses intestinal mucosal barrier function (Zhang et al., 2018). In the present study, no significant differences in serum D-lactate concentration were observed among all groups, indicating that the barrier function of the intestinal mucosa was not disturbed after replacing FM with SM.
Biotechnology elements (growth-related genes) such as GHR, IGF-I, and IGF-II are also used as biomolecular tools to evaluate growth response in fish studies (Picha et al., 2008) and to evaluate the efficacy of commercial feeds and plant proteins (Mzengereza et al., 2021). The present data indicate that the relative expression of the growth-related genes GHR, IGF-I, and IGF-II was not affected by the replacement of FM. In agreement with the present results, no significant changes in the relative expression of IGF-I and IGF- II were reported in red sea bream liver upon replacement of 24% of fish meal with soybean meal (Mzengereza et al., 2021).
5 Conclusion
The results of the present study show that the substitution of 50% of FM by SM with a small amount of oligofructose does not compromise the growth performance or the immune system of pikeperch. This substitution is feasible and provides a reference for cost-optimised design of feed formulations for pikeperch.
