1 Introduction

Yellow mystus (Hemibagrus nemurus) is a river catfish found in most habitat types, but most frequently in large muddy rivers with a slow current and soft bottom (Kottelat, 1998). This species is distributed across South-East Asian countries including Thailand, Laos, Cambodia, Vietnam, Indonesia and Malaysia (Rainboth, 1996). Yellow mystus is usually marketed as fresh fish and also serves as a highly priced aquarium fish (Rainboth, 1996; Ng and Rainboth, 1999). Artificial spawning using the heteroplastic pituitary extract in combination with human chorionic gonadotropin (HCG) has been successfully developed (Thalathiah et al., 1988, 1992). It is widely used in culturing of economically important freshwater fish species in Thailand (Amornsakun et al., 1998). As yellow mystus is a relatively new species for intensive aquaculture, the optimization of practical protocols for commercial production is still incomplete.

Compensatory growth is characterized by a phase of accelerated growth, in terms of weight gain, following a period of restricted feeding (Nicieza and Álvarez, 2009). This phenomenon can be used to enhance growth and feed utilization in many fish species (Tian and Qin, 2003; Foss et al., 2009; Tian et al., 2010; Urbinati et al., 2014). Fish farmers can benefit from unchanged or even improved productivity, while the effort to feed the fish is reduced (Känkänen and Pirhonen, 2009). On comparing growth performances between periodically restricted access to food and unrestricted access, the results can vary widely with overcompensation, full, partial or no compensation (Ali et al., 2003). While such compensatory growth has been studied in several species, there is no prior study on the response of yellow mystus to periodic feed restrictions.

Either increased feed intake and/or improved feed efficiency is needed for faster growth, as in the compensatory growth of fish (Ali et al., 2003). The activities of digestive enzymes may help understand the responses in digestive machinery during physiological acclimatization (Chan et al., 2008; Furné et al., 2008; Abolfathi et al., 2012; Pujante et al., 2015), as well as help resolve nutritional problems under feed restrictions. Carcass composition and muscle quality are quality criteria relevant to human consumption, complementing information on mass growth rates (Jobling et al., 1994; Heide et al., 2006; Foss et al., 2009). The main purpose of this study was to assess the compensatory growth of yellow mystus, when subjected to periodic feed starvation and refeeding. The assessment was based on experimentally determined growth performance, feed utilization, specific activities of digestive enzymes, carcass composition and muscle quality.

2 Materials and methods

2.1 Cyclical starvation and refeeding trial

Juvenile yellow mystus (7.12 ± 0.14 g initial body weight and 8.87 ± 0.04 cm initial length) were obtained from a private farm in Trang province, Thailand. The fish were acclimatized for 1 week in round fiberglass tanks (2 m diameter) with a 20 cm water level. They were fed twice daily (08.00 and 18.30 h) to satiation with a commercial pellet diet (MN32; Lee Feed Mill PCL, Bangkok, Thailand) for carnivorous fish (containing ≥30% crude protein, ≥3% crude lipid, ≤8% crude fiber and ≤12% moisture as feed basis). Subsequently, screened fish with similar weight and length were randomly distributed to each aquarium (90 × 45 × 42 cm with a 20 cm water level). Each aquarium had ten fish as a treatment group. In the feeding treatments, the fish were starved of feed for one day per week (1DPW), two (2DPW), three (3DPW) or four (4DPW) consecutive days per week, and fed ad libitum on the remaining days. No feed starvation was imposed in the control treatment (0DPW). Each aquarium was covered with black plastic to reduce stress due to feed starvation, and contained two hollow plastic tubes for concealment. The experiment was conducted for 6 weeks under a 12-h light/12-h dark cycle. The water was refreshed every other day by 20% replacement, and continuous aeration was supplied by air compressor pumps. The water quality parameters pH and temperature (PH500; Clean Instruments, New Taipei, Taiwan), and dissolved oxygen (DO500; Clean Instruments, New Taipei, Taiwan) were monitored using a water analyzer every week. Ammonia nitrogen (phenate method) was analyzed according to APHA, AWWA and WPCF (1998). The growth performance was monitored by recording weight and length at the end of the experimental period. Uneaten feed was collected 1 h after feeding (twice daily), dried at 60 °C until constant weight, and the determined weight was used to calculate the feed intake (FI), the feed conversion ratio (FCR), and the protein efficiency ratio (PER). These parameters were based on the dry weight of diet consumed, and were calculated per individual fish. At the end of the feeding treatment trial (the last day of refeeding), all the fish were starved for 24 h and then sacrificed by chilling in ice. The fish preparation for sacrifice conformed to “Ethical Principles and Guidelines for the Use of Animals for Scientific Purposes (Sections 1.4 and 4.5.3)”, National Research Council, Thailand. Liver, stomach, intestine and white muscle (under dorsal fin) were dissected, weighed and then kept at −20 °C until used. The whole fish carcass (body) was minced before determining its composition.

2.2 Digestive enzyme studies

2.2.1 Extraction of digestive enzymes

The frozen stomach and intestine were homogenized using a micro-homogenizer (THP-220; Omni International, Kennesaw, GA, USA) in 0.2 M phosphate buffer at pH 8 (1:5, w/v). The homogenate was centrifuged at 15,000 × g, at 4 °C for 30 min, the lipid layer on the surface was removed, and the supernatant was kept at −20 °C.

2.2.2 Protein concentration

Determination of protein concentration was based on the method of Lowry et al. (1951). Bovine serum albumin (BSA) was used as the protein standard. The protein concentrations in the crude enzyme were used for quantifying digestive enzyme specific activities (U mg protein−1).

2.2.3 Determination of digestive enzyme activity

Pepsin (EC activity was assayed using casein as substrate according to Rungruangsak and Utne (1981). The specific activities of trypsin (EC and chymotrypsin (EC were assayed using N-benzoyl-L-Arg-p-nitroanilide (BAPNA) and N-succinyl-Ala-Ala-Pro-Phe-p-nitroanilide (SAPNA) as the substrates, respectively, as described in Rungruangsak-Torrissen et al. (2006). Amylase (EC activity was determined based on Areekijseree et al. (2004) using soluble starch as substrate. Lipase (EC activity was analyzed based on Winkler and Stuckmann (1979) using p-nitrophenyl palmitate as the substrate. Products of the five assayed enzymes were compared against standard L-tyrosine (A720), p-nitroanilide (A410), p-nitroanilide (A410), maltose (A540) and p-nitrophenol (A410), respectively.

2.3 Carcass composition

The moisture, ash and protein contents were determined according to the standard method of AOAC (2005). The lipid content was extracted using ethyl acetate as described in Supannapong et al. (2008). Lipid/LBM (lean body mass) was calculated from the ratio of lipid to sum of protein and ash. All values are given as % on wet weight basis.

2.4 Muscle quality

2.4.1 RNA and protein concentration

The concentrations of RNA and protein were determined using Trizol reagent (Invitrogen, Carlsbad CA, USA) as described in Rungruangsak-Torrissen (2007). The extinction coefficients for RNA and protein used in the calculations were E260 = 40 μg RNA mL−1 and E280 = 2.1 mg protein mL−1, respectively.

2.4.2 Thermal transition characteristics of muscle protein

Thermal properties including onset (T0), peak (Tp) and conclusion (Tc) temperatures of protein denaturation, and the transition enthalpy (ΔH), were studied using a differential scanning calorimeter (DSC7; Perkin Elmer, Waltham, MA, USA). Twenty milligrams of a defrosted muscle sample was placed in an aluminum pan, sealed, allowed to equilibrate at room temperature, and then heated with comparison against an empty reference pan. The thermal properties were recorded for temperatures from 35 to 95 °C, scanned at a rate of 5 °C min−1. Muscle myosin, actin and sarcoplasmic protein were identified based on their thermal transition properties according to Skipnes et al. (2008).

2.5 Statistical analysis and calculations

The observed data are summarized as mean and SEM, and were analyzed using SPSS Version 14 (SPSS Inc., Chicago, USA). Duncan's multiple range test, with significance equated to P < 0.05, was used to test the significances of differences between means. The calculation of growth and feed utilization parameters was as follows: where Wt = mean weight (g) at day t, W0 = mean weight (g) at day t0. where F = dry feed fed (g), W0 = average initial body weight (g), W1 = average final body weight (g), N0 = initial fish number, N1 = final fish number, t = rearing period (day). where ΔT = average WG in treatment group (g)/number of feeding days (day), ΔC = average WG in control group (g)/number of feeding days (day).

3 Results

3.1 Water quality

The cyclical starvation and refeeding had no effects on the monitored water quality parameters (P > 0.05, Table 1). The pH, temperature and dissolved oxygen were similar across the five feeding treatments. A significant decrease in ammonia nitrogen was only observed in the fish deprived for 4DPW relative to the 0DPW control group.

3.2 Growth performance and feed utilization

Over the duration of the experiment, the counts of feeding days in the 0DPW, 1DPW, 2DPW, 3DPW and 4DPW groups were 42, 36, 30, 24 and 18 days, respectively. Compensatory growth, as observed by body weight, was observed in the fish deprived 3DPW (Table 2). The control 0DPW and 3DPW treatments had no significant differences in total length, CF, HSI, FI, FCR or PER, while the SGR was significantly decreased (P < 0.05) by the cyclical starvation and refeeding treatment. Starvation for 2DPW gave inferior growth performance relative to control, observed in all the above parameters. The fish deprived 1DPW had better growth performance than the 4DPW group. However, based on CC analysis, compensation (CC > 1.0) was clearly observed in the 3DPW group (CC = 1.38), followed by the groups 4DPW (CC = 1.20) and 2DPW (CC = 1.10), while the 1DPW group was inferior (CC = 0.86) (Fig. 1).

3.3 Digestive enzymes

Some aspects of physiological acclimatization in relation to intermittent feeding are depicted in Figures 2 and 3. There were no differences in pepsin specific activity across the five feeding treatments (Fig. 2a). Fish starved 4DPW had significantly higher trypsin specific activity than the other groups (Fig. 2b). Chymotrypsin specific activity was highest in the 4DPW group, and also 1DPW and 2DPW had elevated activities relative to 0DPW and 3DPW (Fig. 2c). The specific activity of amylase was unaffected by the feeding treatments (Fig. 3a). The lipase specific activity was similar in the 0DPW, 3DPW and 4DPW groups, while it had lower activity in the 1DPW and 2DPW groups (Fig. 3b).

3.5 Muscle quality

Cyclical starvation and refeeding had no significant effects on RNA and protein concentrations in the white muscle of the reared fish (Table 3). The RNA/protein ratio was similar in the 0DPW, 1DPW and 4DPW groups, while it had significantly lower values in both the 2DPW and 3DPW groups. The thermal transition properties of the major muscle proteins (including myosin, actin and sarcoplasmic protein) had similar characteristics across the five feeding treatments. The denaturation responses of the three proteins in the control group are depicted in Figure 4. The amounts of native myosin and actin, based on enthalpy response, did not differ between the feeding treatment groups (Table 3). The sarcoplasmic proteins differed only between the 1DPW and the 4DPW groups.

4 Discussion

Induced compensatory growth has been observed in a wide range of fish species when periodic feed starvation is followed by feeding to satiation, in other words with cyclical starvation and refeeding (Ali et al., 2003). In the current study, our results show that the juvenile yellow mystus can compensate for starvation on three consecutive days per week if fed to satiation on the remaining days, at least in terms of body weight, although the SGR was significantly lower than in the control 0DPW group. Within the studied period, the other feeding treatment groups could not recover their loss of growth relative to the control group, as indicated by loss of body weight, SGR or PER. However, in a prolonged experiment, accelerated growth might dominate, as indicated by the CC analysis for the 2DPW and the 4DPW groups, but not for 1DPW. This value is considered proof of compensation growth, as observed in pikeperch, Sander lucioperca (Mattila et al., 2009) and rainbow trout, Oncorhynchus mykiss (Taşbozan et al., 2016). Bavčević et al. (2010) reported compensation in body weight of gilthead sea bream (Sparus aurata), but not length, under restriction and refeeding cycles. Our findings were contradictory to this, in that the length also increased along with fish weight, and the proportion between weight and length remained unchanged as indicated by CF. Our findings, however, agree with the changes of weight, length and CF in juvenile whitefish (Coregonus lavaretus) that were not fed during weekends, and that were compared to fish fed every day (Känkänen and Pirhonen, 2009).

Liver weight correlates positively with the body weight of fish (Känkänen and Pirhonen, 2009), while the relative index (HSI) indicates the ratio of its mass and the body mass. Decreases in both liver mass and HSI are known in fish during periods of undernutrition and increases in both occur with the overcompensation or compensation when feeding restrictions are removed (Weatherley and Gill, 1981; Gaylord and Gatlin, 2000). Therefore, not having differences in HSI probably indicates that there was no malnutrition despite periodic feed starvation. Further analyses such as hematological parameters and liver histopathological examination could be used to assess this hypothesis. Generally, fish can adjust their behavior in response to energy reserves to optimize energy intake against the risk of starvation (van Dijk et al., 2002; Näslund and Johnsson, 2016). Considering the feed utilization parameters, the feeding treatments had no effects on FI, FCR or FER (P > 0.05). This indicates that the fish in the periodically feed starved groups ate more per meal in order to maintain their average FI. Moreover, based on our water management, this feeding schedule maintained the water quality, and all the quality parameters were within the standard requirements for fish farming (Zweig et al., 1999). The 4DPW treatment group had significantly reduced ammonia concentrations relative to the control. A possible mechanism for reducing ammonia excretion may be associated with significant upregulation of proteolytic activities, mainly trypsin and chymotrypsin, which reduce the amount of waste nitrogenous compounds excreted by the fish (Mo et al., 2016). The ecological implications of improved water quality in aquaculture systems, from optimal feeding protocols, should be of interest.

Fluctuations in feed utilization have been reported in various studies, with periods of cyclical starvation and refeeding (Tian and Qin, 2003; Foss et al., 2009; Tian et al., 2010; Urbinati et al., 2014). Zaldúa and Naya (2014) suggested that there is a progressive decrease of intestinal mass with starvation time and an increase of gut mass during refeeding, and these could involve changes in the enterocyte turnover rate and intestinal epithelial configuration. Observation of digestive functions through enzyme activities could help understand physiological acclimatization to a feeding regimen. Chan et al. (2008) and Pujante et al. (2015) reported no difference in the pepsin specific activity between groups of starved and refed tilapia (Oreochromis mossambicus), or of thick-lipped grey mullet (Chelon labrosus), whereas either the trypsin or chymotrypsin specific activity showed significant differences. Both these prior reports are in agreement with our observations in juvenile yellow mystus, suggesting that pepsin is less sensitive than trypsin and chymotrypsin to the feeding strategy (Rungruangsak-Torrissen et al., 2006).

About 40–50% of ingested dietary proteins are digested in the intestine by trypsin (Eshel et al., 1993). This enzyme regulates its own activity and many zymogens. The highest activity of trypsin in the fish deprived 4DPW might indicate insufficient protein intake causing an excessive production response. The fact that FI, FCR and PER were not affected by the cyclical starvation and refeeding (Morshedi et al., 2016) is due to the fish adapting in their efficient utilization of food (Wang et al., 1998). Moreover, protein intake is associated with growth by complicated mechanisms, suggesting that the effects of cyclical starvation and refeeding seen in trypsin activity alone should be small. On the other hand, no proteolytic enzyme activity was significantly reduced with a decreasing feed starvation period, suggesting that protein catabolism was well maintained or increased in the other treatment groups relative to the control. A similar type of response has been observed in juvenile roach (Rutilus rutilus caspicus) when feed deprived for 1–3 weeks and then refed (Abolfathi et al., 2012). As for chymotrypsin, this enzyme has different active sites than trypsin and responds to different dietary proteins. Its relatively high activity in the 1DPW and the 2DPW groups suggests that the various enzymes respond in individually different ways to control protein utilization. Elevated activity of this enzyme was associated with a slow growth rate in a study by Rungruangsak-Torrissen et al. (2006) and by Chan et al. (2008).

Since glucose is an essential energy source for a number of tissues, it is particularly important to maintain the levels throughout starvation (Romijn et al., 1990). The amylase specific activity was unaffected by feeding treatment, indicating that the juvenile fish had similar abilities for carbohydrate digestion. This digestive function relates to the maintenance of energy and is necessary for metabolic homeostasis. Our findings agree with the expression of amylase in rainbow trout (Furné et al., 2008) and in thick-lipped grey mullet (Pujante et al., 2015). Generally, carnivorous fish diets contain abundant proteins and lipids, and high lipase activity contributes to successful digestion of the lipids in food (Chakrabarti et al., 1995). The rate of compensation in these treatment groups might be affected by lipid metabolism. Overall, it appears that trypsin, chymotrypsin and lipase are sensitive to cyclical starvation and refeeding and play important roles in utilizing nutrients. In terms of these enzymes' activities, our four experimental groups had different strategies to control their nutrient homeostasis. The successful growth compensation in the 3DPW group was enabled by maintaining the activities of the observed enzymes. The 4DPW group physiologically acclimatized to restricted dietary protein by controlling the activities of the key proteolytic enzymes, trypsin and chymotrypsin, to improve protein digestion. Yarmohammadi et al. (2013) suggested that lipids were the preferred nutrients for mobilization in juvenile Persian sturgeon (Acipenser persicus) during starvation periods. Therefore, increased activity of chymotrypsin in association with growth reduction, but with decreased lipase activity, indicate insufficient nutrients for growth in both the 1DPW and the 2DPW groups. However, the fish in both the 3DPW and 4DPW groups were higher in lipase activity than in 1DPW and 2DPW. Sacristán et al. (2014) proposed that with food absent for a long period and then refeeding, the de novo synthesis of digestive lipase would be stimulated, inhibiting the use of stored lipids as energy by intracellular lipase. Similar levels of lipase activity in the 3DPW and 4DPW groups as in the control 0DPW group might be due to boosting of mechanisms that improved nutrient utilization.

The proximate composition of fish at the end of experiment was unaffected by treatment and similar to that of the control fish. This indicates that the juveniles can defend their proximate composition in the face of feed cyclical changes, and this aspect appears to be more important than accelerating growth, at least in some of the treatment groups. Similar proximate compositions between the deprived (one week starvation and two weeks subsequent refeeding) and control (continuous feeding) groups have been reported previously in gibel carp (Carassius auratus gibelio) and in Chinese longsnout catfish (Leiocassis longirostris) (Zhu et al., 2004). However, long-term starvation can significantly change the carcass composition of juvenile tongue sole, Cynoglossus semilaevis (Tian et al., 2010). Tian and Qin (2003) reported no treatment effects on protein, ash and moisture, but on lipid and lipid/LBM, in barramundi (Lates calcarifer) experiencing starvation and refeeding cycles. The decreased lipid/LBM was considered an indicator predictive of compensatory growth response, based on the lipostatic model (Jobling and Johansen, 1999). The unaffected lipid/LBM in our findings suggests that the observed compensatory growth of this species was unrelated to the lipostatic model.

White muscle is a reservoir for metabolism and protein growth (Carter et al., 1995). Therefore, the muscle quality parameters are more sensitive than the body composition to starvation-refeeding cycles, and show physiological changes. The fish with a higher growth rate had a lower RNA/protein ratio (Sunde et al., 2001; Thongprajukaew et al., 2013). Therefore, the high ratios in the 2DPW and the 3DPW treatment groups indicate superior protein synthesis compared to the 1DPW group. However, there were no differences in the RNA/protein ratio between the starvation treatments as compared to the control 0DPW group. van Dijk et al. (2005) reported no change in the RNA/protein ratio during 21 days of starvation in juvenile roach. A similar finding was also observed in juvenile rock carp (Procypris rabuidi) that were starved for 1, 2 and 3 days followed by refeeding (Yun et al., 2012). These findings indicate that the response in protein synthesis capacity (RNA/protein ratio) varies by fish species, and variations may also be expected in optimal cyclical starvation and refeeding intervals. Data on the thermal transition properties indicated the presence of some major proteins (actin, myosin and sarcoplasmic protein) in the muscle. The ΔH value relates to the amount of native proteins that require the most energy for full denaturing (Matos et al., 2011). The similarity of ΔH values indicates normal physical exercise across the feeding regimens (Thongprajukaew et al., 2015).

5 Conclusions

The current study investigated juvenile yellow mystus (Hemibagrus nemurus) subjected to periodic feed starvation-refeeding cycles that could provide farmers savings in terms of labor costs. Starving the fish for three consecutive days per week and then refeeding on the remaining days induced clear growth compensation, sufficient for competitive growth of the juvenile fish. This choice was near optimal, as decreasing the number of weekly feeding days gave inferior growth, except for the control case with regular daily feeding. Partial compensation by accelerated growth was also observed in fish fed two or four days weekly. Further period choices in alternating between starving and refeeding might also improve the compensation. The findings from this study provide an alternative feeding schedule for the aquaculture production of yellow mystus, with potential benefits to labor management.
