The Cost

<p><em>The aim of the work was to reduce the cost of the food produced and to value blood from poultry. It consisted of collecting the poultry blood, turning it into flour and incorporating it into the feed intended to feed Clarias gariepinus fry. Next, an attempt was made to determine the effect of the poultry blood incorporated in the locally produced feed on the growth of Clarias gariepinus fry. To do this we substitute completely the fishmeal that was used, which is expensive with the blood</em><em> </em><em>meal that is found to be free. Thus, three lots of 100 Clarias gariepinus fry of 2.01g mean weight were placed in three fiberglass tubs. In each tub we have distributed a specific feed. For each type of food a quantity of 2.5kg was used. A daily ration of 5% of fry biomass was used throughout the study. They were fed 9 times a day. It is noted that the industrial food is better but there is no significant difference between locally made foods that based on fishmeal and that with poultry blood</em><em> </em><em>meal. So it is possible to replace fishmeal with poultry blood</em><em> </em><em>meal in locally made feeds.</em></p>

Fish is highly nutritious, tasty, and easily digestible. It is much sought after by a broad cross-section of the world’s population, particularly in developing countries as it provides the cheapest protein source. Nigeria is blessed with numerous inland freshwater rivers and lakes scattered all over the country. This freshwater habitat consists of many species of fish that have successfully dominated all niches over time and have for many reasons remained unstudied. The situation concealed a lot of scientific information particularly on food security and safety to the inmates and the country at large. Jega River which transcended many States in the North-Western part of Nigeria to open into the river Niger is one of such rivers largely uncared for, study-wise. African catfish (Clarias gariepinus) and Tilapia (Tilapia zillii) have been wisely selected for the present proximate composition studies. The juveniles of these fishes were purchased from local fishermen in Mariner Waje landing site of the river which flows by Jega town, a local government area in Kebbi State, Nigeria. For the study, the methodology approved by the Association of Official Analytical Chemists (AOAC) was used to determine the proximate composition of the fishes. The highest percentage crude protein content of 49.18 ± 0.30% was observed in juvenile female C. gariepinus; while the lowest protein content of 39.22± 0.50% was observed in juvenile male T. zilli. The highest percentage lipid content of 11.75± 1.50% was observed in juvenile female tilapia; while the lowest percentage lipid content of 6.25± 0.29% was observed in male African catfish. The highest percentage fibre content of 4.00 ± 0.29% was observed in male and female C. gariepinus, while the lowest percentage fibre content of 0.75± 0.29% was observed in male tilapia. There were variations (p< 0.05) when the protein and lipid contents of both the species were compared with each other. There was also a significant difference (p< 0.05) when the carbohydrate contents were compared between the fish species, but there was no significant difference (p > 0.05) when the fibre content was compared within the species. The analyses showed that both the male and female fish species studied had high protein contents.

An experiment was designed to study the effects of curcumin and thyroxine hormone supplementation in the diet to improve the reproductive performance of catfish broodstock by improving egg quality that eventually increases the production of seedlings. Catfish used in this experiment were supplemented with curcumin and thyroxine hormone through their feeds for 12 weeks. The results showed that there was no significant difference (p > 0.05) in the hepatosomatic index (HSI), gonadosomatic index (GSI), percentage of gonad maturity, total cholesterol concentration in the spawned eggs, high density lipoprotein (HDL) concentration in the spawned eggs, fertilization rate of spawned eggs, and hatching rate of fertilized eggs.  However, there were significant differences (p < 0.05) in the concentration of vitellogenin in the spawned eggs, egg diameter of the spawned eggs, and the triglycerides contents of spawned eggs. It was concluded that curcumin and thyroxine supplementations of African catfish increased vitellogenin concentrations and diameters of spawned eggs that have great potential to improve the reproductive performance.

Comparative study on African catfish hypophysation indices using ovaprim and chicken pituitary gland extract (CPGE) was carried out. Sixteen (16) African catfish brood stocks between 1100 and 2300 g in ratio 2:1 and four (4) numbers of layer birds (Gallus gallus domesticus) between 1200 and 2200 g in ratio 1:3 were used respectively. The experiment was batched into “A” and “B”. Batch ‘A’ was placed on ovaprim while batch ‘B’ was placed on CPGE. An indoor hatchery vat, measuring 0.6096 m x 1.8288 m x 0.3048 m each was used for the incubation. Digital measuring kits were used to monitor water quality parameters and measurement of the brood stocks weights independently. Brood stocks on ovaprim and CPGE treatments had the following mean hypophysation indices in these order: fecundity (11100±7690 and 17760±13863), latency period (9.53±0.54 and 9.77±0.49), fertilization percentage (94.03±5.90% and 90.6±10.11%), hatchability percentage (75.6±0.81% and79.35±10.27%), number of eggs produced (5889±657.37 and 9403.33±589.80), total number of larvae hatched (4717.33±1111.0 and 7111.33±506.64), SGR (0.67±0.31 and 1.1±0.31), and survival rate (64.81±0.71 and66.24±2.19) respectively. There was no significant difference (p = 0.05) in the mean values of fecundity, latency period, fertilization and hatchability percentages in both treatments but there was significant difference (p ≤ 0.05) in number of eggs produced and total number of larvae hatched in both treatments. The water quality parameters were within the range for induced breeding techniques and there was no significant difference (p= 0.05) in both experiments. Both ovaprim and CPGE had excellent results from the induced breeding of Clarias gariepinus and yielded good results. Therefore, CPGE could be recommended from the view point of excellent results and its availability from chicken slaughter houses as against ovaprim which are imported.

A 56 day study was carried out to evaluate effect of temperature changes on survival, growth performance and haematology of Clarias gariepinus fingerlings fed housefly maggot meal (magmeal) diet. Ninety (90) Clarias gariepinus fingerlings, (initial mean weight 4.33±0.03g) were subjected to different environmental regulated temperature conditions in three locations (laboratory, outdoor, greenhouse). The observed average temperature was 26.53±0.01°C, 26.06±0.01°C and 31.52±0.00°C for laboratory, outdoor, greenhouse, respectively. Ten fingerlings stocked per experimental tank were fed in triplicates at 5% body weight in two portions per day. It was observed that different water temperatures affected fish growth. All experimental fish in the greenhouse died after 8 days of exposure. This happened around 14.00 hrs when water temperature reached 40°C. There was no significant difference (P<0.5) in final weight, weight gain, food conversion ratio and standard growth rate among the fish reared in the laboratory (26.53°C) and outside tanks (26.06°C), respectively. The initial carcass crude protein (Cp) value was 58.97%. At the end of the experiment fish reared in the laboratory had a crude protein value of 63.97±0.06% Cp and those reared outdoor (26.06°C) had 71.28±0.00% Cp. No significant difference in values of packed cell volume; white blood cell; haemoglobin and mean corpuscular haemoglobin concentration was found between fish reared in laboratory (26.53°C) and outside (26.06°C). However, the red blood cell (RBC); mean corpuscular haemoglobin and mean corpuscular volume showed significant difference (P>0.05). The result confirms that Clarias gariepinus fingerlings reared at a mean temperature of 26°C (within the recorded optimal temperature range for good growth) performed well. Clarias gariepinus fingerlings are not able to survive when water temperature reaches to 40oC.

The aimed of this research was to evaluate the effects of dietary probiotic microcapsules B.cereus P22 and S. lentus (L1k) at different dose and frequency on growth performance, immune response and resistance of African catfish infected with A. Hydrophila. Probiotics used in this study were B. cereus P22 and S. lentus L1k encapsulated by spray draying method. The research was carried out for 56 days with eight treatments and four replications. The treatments were K- (negative control), K+ (positive control), A (feed supplemented with 0,5% of microencapsulated probiotic, fedevery day), B (feed supplemented with 0,5% of microencapsulated probiotic, fed once every three days), C (feed supplemented with 1% of microencapsulated probiotic, fed every day), D (feed supplemented with 1% of microencap-sulated probiotic with an administration once every three days), E (feed with 2% of microencapsulated probiotic with an administration every day) and F (feed with 2% of microencapsulated probiotic with an administration once every three days). On day 42, all of the fish except K- were challenged by intramuscular injection of A. hydrophila (108 CFU ml-1). In 40 days after infection, there were no significant difference on survival rate (SR) between treatments (p> 0.05). Treatment E displayed the higher growth rate (4,54±0,02%), total probiotic B. cereus (P22) and S . lentus (L1k) (4.06± 0.09 log CFU g-1; 4.02±0.08 log CFU g-1) than other treatments; whereas treatment D showed the best feed conversion rasio(1.191±0.013), and treatment F offered the highest total bacterial count (7.11±0.53 log CFU g-1). An administration of 2% microencapsulated probiotic in every day frequency demonstrated the better growth performance, immune res-ponse and resistance of African catfish to A. hydrophila compare with other treatments. AbstrakPenelitian ini bertujuan untuk mengkaji dosis dan frekuensi pemberian mikrokapsul probiotik melalui pakan terhadap kinerja pertumbuhan, respons imun, dan resistensi ikan lele yang diinfeksi Aeromonas hydrophila.

This study was conducted to evaluate the effect of the substitution of fishmeal by Lima bean flouron the growth performance, survival rate and feed cost of Clariasgariepinusbetween March and May 2018 within the AIO ICG of the Batié District. It also aimed to contribute to the development of alternative sources of animal protein on a global scale. For this purpose, 300 fry of Clariasgariepinuswith an average weight of 3 ± 1.41g were divided into five batches and fed three times a day with rations corresponding to 5% of their ichthyobiomass. The rations R0, R25 R50, R75 and R100 respectively corresponded to the substitution rates of 0, 25, 50, 75 and 100% of fish meal by that of Lima bean. The physic-chemical characteristics of the water (pH, temperature, dissolved oxygen, nitrites and nitrates) were measured daily. The following results were obtained: The highest weight gains were obtained with the rations R25 (20.56 ± 0.40 g), R50 (20.64 ± 0.32 g), R75 (20.98 ± 0.46 g) and the lowest with the rations of R100 (16.21 ± 0.28 g). The highest average daily gain were 0.36 ± 0.02 g; 0.37 ± 0.01 g ; 0.38 ± 0.01 g respectively for the R0, R50 and R75 rations and the lowest with R100 (0.29 ± 0.01 g). The highest value of the specific growth rate (2.47 ± 0.07%) was obtained with the ration R0 and the lowest (1.61%) with the ration R100. The consumption index reached its highest and lowest values with the rations R100 (4.74 ± 0.42) and R50 (3.57 ± 0.43) respectively, compared to the value of the ration R0 (3.31 ± 0.37) for this parameter. Concerning the condition factor K, the highest value was recorded with the R50 diet (1.11 ± 0.49) while the lowest value was obtained with the R75 diet (0.95 ± 0.45). The cost of producing one kilogram of food was higher with the R25 ration (504.59 FCFA) and lower with the R100 ration (443.20 FCFA). Our results revealed that incorporating 75% Lima bean flour into the feed increases the growth performance of Clariasgariepinus fry and reduces the cost of food production.

Zinc (Zn) is an important trace element in fish diets that is required for growth, immunity and antioxidant defense mechanisms. The current study assessed the effects of both organic and nanoparticle zinc oxide (ZnO and ZnO-NPs, respectively) on growth performance, immune response and the antimicrobial effect against Pseudomonas aeruginosa in African catfish Clarias gariepinus. Fish were fed either a control diet or diets supplemented with organic ZnO at concentrations of 20 and 30 mg kg-1 or ZnO-NPs at concentrations of 20 and 30 mg kg-1. After 60 d, a subset of the fish was injected intraperitoneally with 3 × 107 CFU ml-1 of P. aeruginosa. Results showed that body weight gain, feed conversion ratio and specific growth rates were significantly increased in ZnO-NPs20 compared to all other groups. The dietary supplementation with 20 mg kg-1 of ZnO-NPs improved the antioxidant status of fish. Moreover, IgM, lysozyme and nitric oxide showed a significant increase in the fish which received the ZnO-NPs20-supplemented diet. A significant upregulation of growth and stress-related genes was seen in the ZnO-NPs20-supplemented group compared to other groups. However, there was no significant difference in the expression of immune-related genes among ZnO-NPs20, ZnO-NPs30 and ZnO30 groups. These findings highlight the potential use of nano-ZnO for improving growth performance, antioxidant status, immunological status and antibacterial activity against P. aeruginosa in African catfish.

Abstract Background The study was conducted to compare parasitic loads of Clarias gariepinus from cultured and natural habitats. A total number of 80 live adults (200–799 g) C. gariepinus comprising of 20 each were randomly obtained from two cultured habitats (ponds) and two natural habitats (rivers). In the laboratory, these fish were all examined for the presence of parasites. Their sexes were identified while the lengths and weights were measured and recorded prior to dissection. The parasites observed were also identified using morphological characteristics. Results Out of the 80 C. gariepinus sampled, 43 (53.75%) were infected and a total of 409 parasites comprising of 141 (34.47%) ectoparasites and 268 (65.53%) endoparasites were observed from the infected fish. The prevalence of parasitic infection in cultured and natural habitats was 20% and 33.75%, respectively. The results showed that there was a significant difference (P < 0.05) in parasitic infection of C. gariepinus obtained from cultured and natural habitats. Parasitic loads were observed to be significantly higher in natural habitat (33.74% and 26.16% for river A and river B, respectively) compared to cultured habitat (20.54% and 19.55% for pond A and pond B, respectively). The prevalence of parasites in relation to sexes of C. gariepinus was not significantly different (P > 0.05) for both habitats. It was also noted that catfishes with body weight 500–599 g had the highest prevalence (100%) both in cultured and natural habitats. Conclusions The study showed that the parasite loads were more in C. gariepinus obtained from natural habitat compared to those obtained from cultured habitat. It is therefore recommended that the sanitary conditions under which fishes are reared in fish pond should be improved and fish stocked from natural habitats or unscreened ponds should be quarantined to eliminate and treat possible parasitic infection before introducing them into other fish ponds.

One hundred and twenty (120) juveniles of African catfish Clarias gariepinus were obtained in May 2015 from a reputable Fish Farm in Enugu to the University Research Farm (latitude 074o North and 082o South, longitude 068o East and 076o West with annual mean temperature of 30oC). The fish were fed for 49 days from June – July 2015 with diets containing 4 different inclusion levels of phosphorus T1 [0.6% P], T2 [0.8% P], T3 [1.00% P], T4 [1.2% P] and T5 [0% P] which served as control diet, to determine optimum P requirement for fish growth at probability level of P < 0.05 between various treatments and control. Each diet was formulated to contain 40% crude protein composed of yellow maize, soybean cake, palm kernel cake and fish meal. Fish fed with graded levels of phosphorus were significantly higher (P < 0.05) than control in FW and MDWG. There was however no significant difference (P > 0.05) in FCR and PER between T1, T2, T4 and control but T3 was significantly (P < 0.05) better in FCR (0.33) than control (0.39). Similarly, T3 was significantly (P < 0.05) higher in PER than control. Fish in T3 had the best growth performance indicative that 1% P is the optimum requirement for the growth of C. gariepinus.Res. Agric. Livest. Fish.4(3): 215-220, December 2017
