Growth Performance of African Catfish (Clarius Gariepinus) Fingerlings Fed on Different Diets of Daphnias as  Live Fish Feed

A comparative study on the growth performance of African catfish (Clarias gariepinus) fed shrimp based diet (SBD), chicken offal based diet (COBD) and coppens feed was carried-out for 22 weeks in concrete tanks measuring 3.5 x 1.7 x 1.5 m3. Triplicate groups of 40 juveniles with average length of 9.15 ± 0.17cm and weight of 20.00 ± 2.58g were stored in each tank. A total of 360 juveniles were used throughout the study. Fish were fed daily at 3% of their body weight through-out the duration of the experiment. The nutrient composition of the 3 nutrients differed significantly at p<0.05. Weight gain (WG) (g) was highest (17189.33 ± 506.61g) in fish fed diet A (Coppens feed), followed by 15045.33±202.42 g (diet B) (SBD) and least (14357.33 ± 108.25 g) (diet C) (COBD). The Growth rate (GR) was highest in fish fed with diet A (111.62 ± 3.29 g/day), followed by 97.69±1.31 g/day (diet B), and least (93.23±0.70 g/day) in diet C. Specific growth rate (SGR) was highest in juveniles fed diet A (2.02 ± 0.02 %/day), followed by 1.94±0.01 %/day for diet B, and least (1.91±0.01 %/day) for diet C. Mean growth rate (MGR) was highest in juveniles fed diet A (11.88 ± 0.29 mg/day), followed by 11.74±0.15 mg/day for diet B, and least (11.69±0.09 mg/day) in fish fed diet C. The WG, GR and SGR varied significantly between the juvenile fish group fed the 3 diets at p<0.05, while MGR did not vary significantly between fish group fed the 3 diets at p>0.05. Fish fed diet A had a higher feed consumption (FC) (41650.00 ± 315.34 g/kg), than that fed diet B (39034.24 ± 86.34 g/kg) and then diet C (38276.00 ± 342.97 g/kg). Juveniles fed Coppens feed did better, with a feed conversion ratio (FCR) of 2.42 ± 0.06, followed by 2.59±0.04 for diet B and 2.67 ± 0.03 for fish fed diet C. Feed conversion efficiency (FCE) was higher in fish fed diet A (41.26±0.94 %), followed by 38.54 ± 0.54 % (diet B) and least (37.52 ± 0.51 %) (diet C). The FC and FCR varied significantly between the fish fed the 3 diets at p<0.05, while FCE was not significantly different between the 3 treatment groups at p>0.05. The water parameters of the culture water varied significantly between each treatment groups (p<0.05), and were within the rage suitable for normal growth of fish. Though coppens feed yielded better growth performance and feed utilisation, the use of COBD and SBD is recommended for fish farmers in Nigeria. More researches should be carried out on using chicken offals and shrimps in fish feed formulation.

A 3-factor -factorial experiment (2K) was designed to produce fish feeds from mixture of pigeon pea, bambara groundnut and fish meal as major ingredients, while maize, red palm oil, salt and micro nutrient pre-mix were added as minor ingredients. The raw materials were processed into flours. The ingredients were weighed out in various ratios and mixed. The mixture was extruded; sun-dried and packaged and labeled F1-F8 and a commercial feed labeled F9 served as control. The feeds were feed to juvenile Clariasgariepinus kept in 9 separate plastic bowels and fed for 42 days. The forty-five fish of uniform weight and age were grouped into 9 and stocked in the nine artificial ponds, each pond contained five fish. The feeds were analyzed for proximate composition, while the growth performance of the fish was evaluated at the end of the feeding period. Result showed that F3 (20g pigeon pea, 20g Bambara ground nut and 16g fish meal) contains the highest protein (33.14 %) and F1(20g pigeon pea, 30g bambara ground nut and 16g fish meal) the least (23.13 %). F3 exhibited the highest specific growth rate (1.14 %) followed by the F9 (control) which contains 1.09%. The highest weight gain (16 g) was observed in the fish fed the control feed. However, F3 and F4 (20g pigeon pea, 30g bambara ground nut and 18g fish meal) ranked next to the control with respect to growth performance. It is therefore possible to produce quality catfish feed from bend of pigeon pea, Bambara ground nut and fish meal. Keywords: catfish, fish feed, bambara groundnut, pigeon pea, fish meal

The Mean

Aquaculture industry is facing challenges of the high cost of fish feed, and therefore it is very crucial to explore the alternative raw materials for feed formulation at the lowest cost. Therefore, the objective of the present study was to evaluate the effect of Plukenetia conophora shells on the growth, haematological and biochemical parameters, and its genotoxicity on African catfish Clarias gariepinus juveniles. Five experimental diets were formulated having three replicates at 0% (0WS), 25% (25WS), 50% (50WS), 75% (75WS) and 100% (100WS) inclusion of walnut shell respectively. The fishes were fed on experimental diet two time a day for 12 weeks. The results showed that the fish in tank 25WS had the best weight gain with the mean of 33.5±5.8 g and the least was recorded in tank 100WS. The specific growth rate was highest in-tank 75WS with the mean value of 0.46±0.05 g was recorded. The highest feed intake was found in fish fed with 25% inclusion of P. conophora. The fish fed with P. conophorashowed increased values of haemoglobin, (12.05±1.63g/dL), Red blood cell, (2.785±0.28µL) and White blood cell, (11.25±4.59µL) compared with control diet values of fish fed of Red blood cell, (1.81±1.54µL) and White blood cell, (5.15±6.57µL). There was a reduction in the haematological value of the fish fed with control feed having Haemoglobin, (10.75±8.13g/dL). The genotoxicity test that was carried out showed that the highest counts of micronucleus were in tank 75WS. The Duncan Multiple Range Test (DMRT) shows a significant difference (p0.05) in the growth performance of the fish. It is concluded that inclusion of 50% P. conophora shells in the feed of C. gariepinus gave no negative impact on the health status and growth performance of the fish.

Feed Digestibility

Cameroon’s fish protein consumption levels remain inadequate due to low fish production. The effects of Light Matrix Organics (LMO), a probiotic combination on the growth performance, feed digestibility, blood and carcass composition of the African catfish, Clarias gariepinus were investigated. Probiotics are live microorganisms which when administered in adequate amounts confer health benefits on the host. A basal diet was formulated and supplemented with LMO at 0.0 ml/kg (T0) as control; 1.66 ml/kg (T1); 2.49 ml/kg (T2); 3.32 ml/kg (T3) and 4.15 ml/kg (T4) and fed to 340 Clarias gariepinus fingerlings in two blocks (with average fish weights of 1.00±0.40 g and 0.1±0.05 g respectively), for sixty (60) days in replicate plastic tanks. Fish were fed twice daily at 4% body weight. Results show that the Mean weight gain, Specific growth rate and Protein efficiency ratio were significantly highest (P<0.05) in fish fed diets supplemented with LMO at 4.15 ml/kg (T4) and lowest in T0 (control). Apparent Digestibility Coefficients (ADC) of C. gariepinus for Dry Matter% and Crude Protein% decreased significantly in the general order: T4>T3>T2>T1>T0, except for Crude Protein which was significantly higher (P<0.05) in T3 than in T4. ADC Lipid% was higher (P<0.05) in both T2 and T4 than in all other treatments while ADC Energy was highest (P<0.05) in T2. Blood parameters were significantly higher (P<0.05) in LMO supplemented diets except for haematocrit (Ht) and red blood cells (RBC). Carcass nutrients differed significantly with LMO supplemented diets producing significantly lower (P≤0.05) fat but storing more energy than fish on the control diet. Incorporating LMO in treatment T2 was significantly more (P<0.05) economically efficient than other treatments. The supplementary use of LMO at the rate of 2.49ml/kg fish feed is therefore recommended based on the high economic efficiency and above average growth performance. Key words: probotic, light matrix organics, Clarias gariepinus, growth performance, digestibility, economic efficiency.

Significant Difference

High cost of qualitative fish feed is one of problems hampering the development and profitability of fish farming and consequently leads to food insecurity in terms of food availability and accessibility. The study was conducted to determine growth parameters and carcass composition of Clarias gariepinus juveniles of mean weight 21.74g+0.54g fed with varying levels of dietary inclusion of Clitoria ternatea seed meal substituted for soybean meal over a period of eight weeks. Four iso-nitrogenous experimental diets were formulated at 0% (control), 25%, 50% and 100% inclusion levels of C. ternatea seed meal. The 8-week feeding experiment was conducted in rectangular plastic tanks, each treatment having three replicates with two feeding regime at 5% body weight and weighed every week. At the end of the intensive feeding period, samples from each treatment were oven dried for nutritive analysis of the fish carcass. The values of mean weight gain for diets I and III were 27.7+1.11 and 27.23+0.94 respectively. Comparatively, the growth parameters values; FI(g), SGR(%), FCR(g), PER(%) and NPU(%) for control diet and diet III were the best with no significant difference (p>0.05). The Carcass evaluation revealed that Diet I had the highest crude protein which was not significantly different (p>0.05) from diet III. It was established that fish fed 50% inclusion level of C. ternatea seed meal had effective comparable biological values with the control diet in terms of growth performance and feed utilization. The total fish production (kg) showed no significant difference (p>0.05) between diets I and III.

Aim: The aim of this study is to assess fermented parkia infusion in feed as organic strategy to improve feed quality and immune system of African catfish (Clarias gariepinus) fingerlings. Place and Duration of Study: Department of Biochemistry, Ibrahim Badamasi Babangida University, Lapai, Niger State, Nigeria, between 1st January 2017 and 25th March 2017. Methodology: In the present study, feed ingredients were fermented for 72 hrs with probiotic starter culture from Parkia biglobosa (TF diet) in comparison to a control diet with similar ingredients to the experimental diets but totally unfermented (CF diet) and used to make feed pellets. The experimental feeds were fed at 5% of body weight of each dietary treatment to triplicate groups of 20 fish per tank (100 Liter capacity), two times daily for 10 weeks. Proximate composition and mineral content of diets and whole fish, Feed efficiency, growth performance and Biochemical parameters of the fish were evaluated. Results: The result of proximate compositions of experimental diets revealed a significantly higher protein and ash contents in TF compared to the CF. Carbohydrate content was significantly lower in TF diet while crude fibre, moisture and fat contents were not significantly higher in CF compared to TF. The highest values of some minerals such as sodium (Na), potassium (K), phosphorus (P) and magnesium (Mg) were also recorded in the TF while the least was recorded in CF. The result of feed efficiency and growth performance indicated similar feed acceptance and intake between fish fed the fermented diet and the control. The activities of serum antioxidant enzymes activities of superoxide dismutase and catalase were significantly (P < 0.05) higher in serum of fish fed TF compared to that in fish fed CF diet. Conclusion: It can be deduced from this study that the fermented diet improved the immunity of fish and does not adversely affect the growth performance.

Positive Effects

In the present study, a possible nature immunostimulant and growth promoter—humic substances (HS) originating from Siberian leonardite mineraloid—were tested on juvenile Clarias gariepinus performance. Feed additive was applied onto commercial pelleted feed at four HS levels—0, 1, 3, and 6% w/w (HS0, HS1, HS3, HS6, respectively). Diets were tested in five repetitions (in total, n = 1800 individuals, mean body weight 28.1 ± 6.2 g) for 56 days. Growth and production parameters, fish condition and somatic indices, and overall mortality were evaluated after 14, 28, 42, and 56 days of exposure. Whereas, plasma samples were collected only after 0, 28, and 56 days, when fish health status was assessed with biochemical parameters (total proteins, TP; alanine aminotransferase, ALT; aspartate aminotransferase, AST; lactate dehydrogenase, LDH; cholesterol, CHOL; triglycerides, TAG) and fish antioxidant status with glutathione (reduced glutathione, GSH; oxidized glutathione, GSSG; glutathione ratio GSH/GSSG). Although a significantly positive effect of HS feed additive on growth performance was not found in the present study, moderately positive effects were found regarding biochemical parameters (ALT, AST, LDH, CHOL, and TAG) and antioxidants (GSH/GSSG ratio) that were improved especially in the HS3 group.
