    AbstractThe effects of dietary Lagnaria breviflora leaves extract (LBLE) on the growth performance, feed utilisation and haematological parameters of juveniles African catfish, Clarias gariepinus (mean = 8.45 ± 0.6 g) raised in a flow water (mean temperature 26.7°C, mean pH 7.52, mean dissolved oxygen 6.05 mg/L) were assessed in this study. Diets (400 g/kg crude protein; 4631.5 kcal/kg gross energy) supplemented with LBLE at levels of 0 (control), 0.5, 1.0, 1.5 or 2.0 g/kg diet were served to fish in triplicates (each replicate has 20 fish) until they appeared satiated for 12 weeks. Then, they were challenged with Aeromonas hydrophila infection for further 2 weeks. Fish served dietary LBLE had considerable higher weight gain (64.76 g) and specific growth rate (765.5% g/day) than the fish group fed with the control diet with a reduced feed conversion ratio (1.45) (p < 0.05). Compared to fish fed with the control diet, the villi height (146.30 µm) and width (284.35 µm) of the intestines increased greatly in a dose (LBLE in diets) dependent order. Similarly, dietary LBLE increased (p < 0.05) the packed cell volume (46.11%) and haemoglobin (17.03 g/dL), whereas 1.5 g of LBLE increased the counts of white blood cells. Glutathione S‐transferase (769.43 U/mg protein), glutathione peroxidase (84.14 U/mg protein) and superoxide dismutase (433.15 U/mg protein) activities were significantly higher (p < 0.05) in fish fed with diets supplemented with LBLE compared to the control one. Additionally, dietary LBLE increased phagocytic and lysozyme activities and protected C. gariepinus against bacterial infections where the lowest death was observed in the fish fed on the diet containing 1.5 g LBLE/kg feed. These findings showed that the fish fed with LBLE/kg diet improved their immune system, antioxidant and growth performance in addition to providing protection from A. hydrophila infection with the optimum dose of 1.80 g/kg diet.

    AbstractEdwardsiella tarda is one of the most common causes of fish diseases that hinder aquaculture. Oxidative stress in farm animals can induce a number of pathological disorders, production and general animal welfare. The use of exogenous dietary nonenzymatic antioxidants such as alpha‐lipoic acid (ALA) can stop a pro‐oxidant state and thus appears to have the potential to modulate the immune system and protect fish from bacterial infection. Thus, this study investigates the stimulatory effect of dietary ALA on growth performance, antioxidant capacity, liver enzymes, immunity and protection of African catfish, Clarias gariepinus (B.), against an infection with E. tarda. Five isonitrogenous and isocaloric diets (400 g/kg of crude protein) containing ALA at doses of 0.0 (control), 500, 1000, 1500 or 2000 mg/kg diet were served to 300 juveniles of African catfish (mean weight = 8.2 ± 0.2 g) adequately thrice per day for 12 weeks. Thereafter, 0.1 mL of E. tarda (ATCC 15947; 1.0 × 108 CFU/mL) was intraperitoneally injected into 10 fish from each tank and was monitored for 14 days. The results showed that ALA‐fortified diets significantly boosted the fish growth, feed consumption and utilization and feed conversion ratio but no did not affect fish survival rate. The highest final fish weight (g), weight growth (g) and weight gain (%) were all considerably higher in fish fed with ALA‐fortified diets (p < 0.05), especially from 1000 to 200 mg/kg ALA than the control group. Also, an enhanced hemato‐biochemical, antioxidant and immune indices were noticed in African catfish‐fed ALA‐enriched diets. In a dose‐dependent order, the levels of haematological indices such Ht, Hb, RBCs, WBCs and platelets were markedly increased (p < 0.05). Additionally, fish fed with ALA‐based diets showed substantial (p < 0.05) declines in aspartate and alanine aminotransferase values, with the lowest values being found in the 2000 mg/kg diet while control group had highest values. Further, African catfish fed the feed fortified with 2000 mg ALA/kg diet showed the highest levels of lysozyme, respiratory burst, proteases and esterase activities (p < 0.05). Following exposure of fish to E. tarda infection, a significant reduction in the mortality was obtained in African catfish fed with ALA‐based diets, especially from 1500 to 2000 mg ALA/kg diet (3.3%); while fish fed with the control diet had highest mortality (86.7%). Therefore, diets supplemented with ALA evoked fish growth performance, antioxidants and nonspecific immunity of African catfish. Also, resistance of African catfish to E. Tarda infection were raised when fed ALA‐fortified diets at optimum inclusion rate of 1300 mg ALA/kg diet.

    The microbial phytase, derived from Buttiauxella gaviniae, Yersinia mollarettiv and Hafnia spp., is proven to be safe for avian and porcine feeding and promotes their overall growth performance. Here, we have evaluated microbial phytase's effects on the growth, bone mineral content, antioxidant status, immune responses and the resistance of African catfish (Clarias gariepinus) fed with high soybean meal-based diets against Aeromonas hydrophila infection. Five isonitrogenous diets (40% protein) were supplemented with different levels of microbial phytase ranging from 0 as a control to 250, 500, 750 and 1000 FTU/kg diet. African catfish (n = 300; 8.5 ± 0.3 g) were allocated in 15 50-L tanks (in triplicates) and were fed on the prepared tested diets for 12 weeks. After the end of the feeding period of 12 weeks, 10 fish from each replicate was intraperitoneally infected with A. hydrophila (0.5 × 105 CFU/ml) and monitored for 14 days. Dietary phytase levels linearly and quadratically improved the growth performance of African catfish and stimulated feed intake. Bone levels of calcium, phosphorus, magnesium and zinc were also positively modulated in phytase-fed fish, especially at 750-1000 FTU/kg diet. Similarly, counts of red and white blood cells as well as haemoglobin, packed cells volume, platelets, lymphocytes and heterocytes were significantly modulated in all fish fed with phytase-supplemented diets. Higher levels of serum total protein, albumin and globulin were also observed in fish fed with a 750-1000 FTU/kg diet of phytase. Conversely, aspartate and alanine aminotransferase activities were lower in fish fed with a 750-1000 FTU/kg diet of phytase, compared to those fed the control diet. Moreover, antioxidant enzymes (superoxide dismutase, catalase and glutathione peroxidase), reduced glutathione levels and immune responses (lysozyme, respiratory burst, protease and alkaline phosphatase activities) biomarkers were linearly and quadratically elevated, while malondialdehyde values were linearly and quadratically decreased in fish groups fed with phytase-based diets. After administering A. hydrophila, 60.0% of the fish fed the control diet perished, while no mortalities were observed in fish fed with 750-1000 FTU/kg diets. Taken together, the current study reveals that dietary phytase could improve the growth performance, blood profile, bone mineralization, antioxidant activities, immunity and overall protection of African catfish against A. hydrophila infection. Dietary phytase may be efficiently used in the feeding of African catfish to enhance their overall performance and mitigate health conditions with optimum level of 900 FTU/kg diet.

    Antinutritional components must be substantially reduced to ensure better utilization of unconventional feeds in animal nutrition. Among the different methods of processing, soaking represents a simple and inexpensive alternative. This study attempted to determine the nutritional properties of socked Jatropha curcas kernel (JCK) and the effect of its dietary inclusions on Clarias gariepinus (n = 50; mean initial weight = 6.19 ± 0.52 g). Three treatments of JCK (i.e., soaking 24, 48, and 72 h) were tested alongside a control group. The result showed that soaking substantially improved proximate composition and reduced anti-nutrient compared to the control JCK. A similar trend of improved performance was observed when the treated JCK was included in diets composed of 35% crude protein; a total of 315 kcal g−1 energy and fed to C. gariepinus for 56 days. Alongside the improvement observed in growth, it was also noted that carcass protein and haematological variables were improved with the dietary administration of soaked JCK. Histological examination of the intestine and liver tissues also revealed fewer signs of histopathological degeneration in the fish, consequent upon dietary inclusion of soaked JCK (i.e., 72 h) compared to those raised on the raw JCK-included diets. It was, therefore, concluded that soaking could be a much easier method of nutritionally improving JCK for the administration to C. gariepinus.

    This study evaluated the effects of cooking for different hydrothermal-treatment durations (10, 20, 30 and 40 min) on the proximate composition, amino acid profile, fatty acid composition and organoleptic parameters of filets of African catfish Clarias gariepinus (Burchell, 1822). Filets of the fish were prepared from market size African catfish with similar breeding history. Parameters of the processed filet under the different hydrothermal durations were also compared against a raw–unprocessed control group except during organoleptic analysis. The results obtained revealed a significant increase in protein, fat and ash content until the 30th minute of hydrothermal processing (p ≤ 0.05). Beyond this processing time, protein and fat significantly reduced while ash remains unaffected. The same trend was observed for most essential/non-essential amino acids isolated as well as the prominent saturated fatty acids, monounsaturated fatty acids and polyunsaturated fatty acids. In all, the raw control group consistently recorded the least values of nutritional components. The perception of assessors was, however, found to be similar (p ≥ 0.05) in terms of organoleptic parameters regardless of the duration of the processing time of the filets. It was concluded that cooking the African catfish filet using the hydrothermal method should not be extended beyond 30 min.

    A feeding trial was conducted to evaluate the effect of pawpaw–onion powder (POP) mixture on the growth, and haemato‐biochemical and antioxidant responses of Clarias gariepinus (4.02 ± 0.01g/fish) for 60 days. Five trial diets were formulated as control (without POP or antimicrobial growth promoter (AGP)), AGP (basal diet + 10ml AGP/kg diet), POP 2.5 (basal diet + 2.5g POP/kg diet), POP 5.0 (basal diet + 5.0g POP/kg diet) and POP 10 (basal diet + 10g POP/kg diet). Two hundred and twenty‐five fish were equally distributed into five groups in triplicate and fed twice daily. The results indicate that AGP or POP supplementation exerted no effects on the growth and blood profile among the various groups, but a significantly higher lymphocyte count was observed in POP 10g/kg. The highest whole‐body protein and lipid contents were noticed in fish fed the control diet (p < .05), whereas POP 5.0g/kg group recorded the highest hepatosomatic value. Furthermore, the cholesterol level was found to be lower in the AGP‐ and POP‐fed fish compared with the higher level recorded in the control. The glucose concentration and superoxide dismutase enzyme activity were found to be higher in POP 2.5‐fed fish, whereas POP 10‐fed fish showed higher catalase activities compared with other groups (p < .05). Based on the result obtained, this study showed that dietary POP had no significant impact on the growth performance but has direct effects on the whole‐body lipid content, lymphocyte count, cholesterol level, alanine aminotransferase, alkaline phosphatase and antioxidant response of Clarias gariepinus.

    ABSTRACT African catfish, Clarias gariepinus (B.), may be wounded naturally due to cannibalism, high density, and/or any other action. These wounds may be a precursor to further pathogen infection, causing health deterioration and economical loss if not well treated. Hence, the wound-healing capability of clove basil (Ocimum gratissimum) leaves extract (CBLE) on African catfish was investigated. A basal diet containing 40% crude protein was formulated and enriched with CBLE levels of 0.0, 5, 10, and 15 g/kg diet. Fish (54.20 ± 1.12 g) were lacerated (1 cm long) in the caudal and lateral regions. After that fish were fed one of the tested diets in a complete randomized design for 14 days, during which wound closures and histological changes were observed. Fish fed CBLE-enriched diets had faster wound-healing percentages and daily healing rates over those fed the control diet. Fish fed lower CBLE levels needed more time to achieve complete wound healing; meanwhile fish fed the 15 g/kg diet showed a complete wound healing (100%) on the 10th and 8th day postwound (dpw) in both lateral and caudal regions respectively. Wound healing in caudal and lateral regions of CBLE-fed fish in response to time period was related to the accumulation of bioactive compounds in fish, which enhanced their antioxidant and immunity. On the 14th dpw, the least healing percentage (88.09%) was recorded in the lateral and caudal regions in fish fed the control diet. On the other hand, the dermal wound in the caudal region healed faster than that in the lateral one; this was because of the variation in tissue composition and texture in both regions.

    Abstract The growth performance, nutrient utilization and health status of Cyprinus carpio fed various levels of Moringa oleifera leaf meal as a replacement for soybean meal was investigated. Six isonitrogenous diets were formulated with Moringa oleifera leaf meal at 0%, 10%, 20%, 30%, 40% or 50% crude protein replacement. The diets were fed to the fish at 5% body weight to 360 Cyprinus carpio juveniles (8.12±0.21 g) allotted to 18 happas (1 m3) in a completely randomized design for 12 weeks. The results revealed that crude protein replacement levels of 30% had significantly better final weight, weight gain, specific growth rate, protein efficiency ratio and feed conversion ratio, while survival rates were not significantly different. Also, haematological, biochemical and immune responses of the fish fed Moringa oleifera leaf meal fortified diets were significantly improved. The results further suggest that higher inclusion replacement is possible but opined that, for growth and economic consideration, Moringa oleifera leaf meal could be used to replace 30% crude protein of soybean in the diet of Cyprinus carpio juveniles.

  • The effect of different feeding rates and restriction on the growth performance of Clarias gariepinus
    Oloyede Tiamiyu, V. T. Okomoda and H. Helen

    This study seeks to investigate the effect of restricted feeding regimes at different rate on growth performance of Clarias gariepinus using static and flow through system. Fingerlings were divided into six batches for each systems with the first and second batch fed at 5% body weight (BW) every day and every other day respectively, the third and fourth batch were fed 10% BW every day and every other day respectively while the fifth and sixth batch were fed 15% BW every day and every other day respectively. Result obtained shows that fish fed every other day exhibited compensatory growth at 5% BW in the static system while in the flow through system fish grow better at all feeding rates when fed every other day. Increasing feeding rate however beyond 10% BW did not improve growth when fed every day or every other day in the static system due to poor water quality. This therefore implies that catfish farming can make more profit feeding African catfish at 5% body weight every other day in the static system and up to 15% body weight (every other day) in flow through system, hence taking advantage of the compensatory growth response phenomenon.

    Cambridge University Press (CUP)
    SummaryThis study was conducted to determine the efficacy of preserved and fresh pituitary extract of Clarias gariepinus (Burchell, 1822) to induced spawning in the same species. Growth performance of fry was also monitored for 15 days to determine the possible effect of natural hormone treatment on the fry. Pituitary glands (PG) were obtained from 12 male broodstocks, six extracted PG were preserved in 96% ethanol 24 h before injection, while the other were extracted and used in their fresh state. The PG solutions (1 g ml−1 of saline water) were injected at 1 ml kg−1 of the female broodstock. Ovaprim® (a synthetic hormone) was used as the control and administered at a rate of 0.5 ml kg −1 of fish. After a uniform latency period of 9 h 30 min, fish were striped, fertilized, incubated and the performance evaluated. Results obtained revealed better hatching performance using Ovaprim® synthetic hormone (64.52%), however, preserved PG gave better hatchability (59.74%) than fresh PG extract (51.39%). After 15 days of feeding ad libitum with shell-free Artemia cysts, the growth of fry spawn with preserved PG was comparable with that of the control, while least performance was observed using the fresh PG. It was concluded that preservation of PG in ethanol 24 h before injection had a positive effect on breeding performance and could be exploited in the commercial production of C. gariepinus fingerlings.

    ABSTRACT The value of toasted Mucuna utilis seed meals was investigated in this study by evaluating the nutritional profile and the utilization of the processed seeds in isonitrogenous (35% CP) and isocaloric diets (17 kJ g−1) for African catfish Clarias gariepinus (Burchell 1822). Toasting the M. utilis seed significantly reduced the levels of tannins, phytate, trypsin, and hemagglutinin in the seeds. However, protein, gross energy, arginine, histidine, and valine were increased (P ≤ 0.05). The processed seed was then used to formulate five experimental diets by progressively increasing its inclusion (by 50 g kg−1) from zero up to 200 g kg−1. A sixth diet was also formulated with raw M. utilis included at 200 g kg−1 to determine the efficacy of the processing method applied in this study. Fifty fingerlings of C. gariepinus (2.02 g ± 0.08) stocked in 18 hapas measuring 1 × 1 × 1 m3 were then fed the diets for 56 days. The growth of C. gariepinus fingerlings was significantly improved by the addition of the toasted M. utilis seed meal. However, fish fed the diet containing 200 g kg−1 of raw M. utilis had poor growth with higher mortality (35%). Estimation of the feeding cost using the diets revealed reduction in production cost of fish with the inclusion of toasted M. utilis seed meal. It was concluded that toasting significantly improved the nutritional quality of this unconventional feedstuff, allowing better utilization at up to 200 g kg−1 inclusion level in the diet of African catfish C. gariepinus.

    Walter de Gruyter GmbH
    Abstract The performance of Clarias gariepinus (Burchell, 1822) fingerlings reared in white, green, blue, black and red coloured tanks was investigated. Each colour was tested in triplicate 1 m3 tanks with an initial stocking density of 100 fingerlings per tank (1.07 g). Fish were fed a commercial diet at 5% body weight per day for eight weeks. Fish weights were sampled every 2 weeks to adjust feeding rates. Tank colour had a significant effect (P &lt; 0.05) on the overall performance of the fingerlings. Rearing in black tanks resulted in a higher daily feed intake (0.44 g) and better growth performance when compared to other tank colours, while the poorest performance was observed in blue and green tanks. Carcass protein and fat content at 8 weeks revealed a trend similar to that observed for growth. Also, serum glucose tests showed higher levels in light background tanks and were thought to be an indication of stress. Survival was not affected by tank colour. It was concluded that dark-coloured tanks such as black or red were better in comparison to light-coloured tanks for the rearing of African catfish fingerlings

    Walter de Gruyter GmbH
    Abstract This study was conducted to determine the effect of storage conditions on the quality of feed and the aftermath effect of feeding fish with such feeds. Three commercial diets used for this study included Coppens®, Multifeed® and Vital feed®. Feed was stored either by opening the bag to the atmosphere (WO), the bag opened with neck tied using a rubber ring to prevent exposure to the atmosphere (OT) or sealed (SC) until the start of the feeding trials. The feed was stored under these conditions for six months. Nutrient analyses revealed significant changes in feeds held under the WO condition when compared with other storage conditions. Nutritive changes also varied with commercial feed type. Mould infestation of the feed was noticeable more in the WO condition of storage compared to the SC condition. After feeding C. gariepinus for fifty-six days, lesions were observed on fish fed mouldy feed held under the WO condition, which led to mass mortalities. Growth performance was higher in all fish fed SC stored feed, and for those fed Coppens® and Multifeed® under OT storage conditions. It is advised that storage of fish feeds up to six months should be undertaken with considerable care and attention.

    Walter de Gruyter GmbH
    Abstract The aim of this study was to determine the effect of different water change frequency on the growth of African catfish Clarias gariepinus. Fingerlings with initial mean weights of 7.02 ± 0.05g were stocked (50 fish each) in fifteen concrete tanks (2×2×2m) and were conditioned under five different treatments of water renewal, namely: TRT1 (no water change), TRT2 (water renewed daily), TRT3 (water renewed after four days), TRT4 (water renewed after eight days) and TRT5 (water renewed after fourteen days). After 56 days of feeding, results revealed best growth performance of fingerlings in tanks with water renewal frequency of TRT3 and TRT4. Similarly, survival was higher in these frequencies compared to the others; the control treatment, however, had the least performance for all parameters measured. It is therefore recommended that water renewal should be done once between four and eight days to enhance growth of African catfish fingerlings reared in a static system.
