African catfish Clarias gariepinus is cultured as food fish, used to control overpopulation in tilapia ponds, and is grown as baitfish for the Lake Victoria Nile Perch fishery. Since the demand for Clarias gariepinus fingerlings is high, many farmers wish to specialize in fingerling production. In this study, the performance of three dietary feed types: freshwater rotifers with Artemia nauplii, freshwater rotifers with fish meal, and freshwater rotifers with maize bran, on the growth performance of African catfish fry, were done in a hatchery and they were raised in 9 glass tanks for a period of 21 days. Pearson’s correlation showed no relationship (r=0.1; P>0.05) between growth and water quality parameters, but indicated a strong relationship between survival rate and total length between treatments (r=0.85; P=0.02). Mean total length (TL) after 21 days were (A=15.003), (B=12.964), and (C=11.90) in mm for Treatments A, B, and C, respectively. Treatment A had the highest specific growth rate (SGR) of 6.475% day 1 followed by B (5.5320% day−1) and C (4.960% day−1). Results from this study demonstrate that after the 7 days of feeding using rotifers, Artemia is the best feed for increasing growth of Clarias gariepinus.

In an effort to contribute to resilient food and nutritional security in urban slums, a food system approach was applied to understand the key socio-economic factors driving fish species consumption in Kibera, the largest informal settlement in Africa located in Nairobi, Kenya. Data were collected from 385 randomly selected households using a structured questionnaire. A multivariate probit model was applied to estimate the relationship between the variables in order to determine the socio-economic drivers of preferences for different fish species. The results indicated that Lake Victoria sardine (Rastrineobola argentea) had the highest preference (73%) among the respondents, followed by Nile tilapia (Oreochromis niloticus) (70%) and Nile perch (Lates niloticus) (23%), respectively, with other fish species at 12%, including African catfish, marbled lungfish, common carp, fulu and tuna (Clarias gariepinus, Protopterus aethiopicus, Cyprinus carpio, Haplochromine cichlids and Thunnus sp., respectively). Large household size showed an increase in preference for the Lake Victoria sardine, while higher income influenced preference for Nile tilapia and Nile perch positively, implying that when more income is available, Nile tilapia is the preferred fish over other fish species. Increased fish prices positively influenced preference for Nile tilapia, which is explained by the willingness to pay extra for quality and origin, for instance, to avoid the cheaply cultivated Chinese fish. In the case of the Lake Victoria sardine, lower prices positively affected the preferences. Religious and cultural practices and beliefs influenced preference for species and consumption of fish. Residents who migrated from western Kenya had a higher preference for the Lake Victoria sardine, while residents born and raised in Kibera had a higher preference for Nile tilapia. Neighbourhood effects reduced the preference for consuming Nile perch. These findings provide insights into future market opportunities for specific target groups. For instance, given that small-sized fish like the Lake Victoria sardine is highly demanded, in order to increase resiliency in food and nutrition security, small-sized cheap Nile tilapia will have a large potential in the future, with ever higher demand specifically from the residents born and raised in Kibera.

Growth performance, feed utilization, survival and body indices of African catfish Clarias gariepinus juveniles fed diets containing maggot meal as replacement of fish meal was evaluated for 42 days. Sixty fingerlings of Clarias gariepinus, average weight of 10 g were randomly distributed into six circular tanks at the rate of 10 fish per tank. There were two treatments, DT1(maggot meal-based diet) and DT2 (fish meal-based diet). The fish were fed twice daily. Water quality parameters were monitored on a weekly basis throughout the experimental period. Growth, nutrient utilization and body indices parameters were evaluated at the end of the experiment. Crude protein, crude lipid and ash were higher in the fish meal-based diet (34.65%, 7.33% and 18.03% in DT2 as against 28.70%, 7.20% and 11.0.1% in DT1 respectively), while crude fibre was higher in maggot meal-based diet. The selected water quality parameters: temperature, dissolved oxygen, ammonia and pH were slightly lower in maggot meal based treatment, but none of them was differently significant. Mean weight gain, specific growth rate, protein intake, protein efficiency ratio, lipid intake and lipid efficiency ratio (17.25±0.70 g, 2.39±0.06 %/day, 95.50±1.27 g, 1.81±0.06, 23.96±0.32 g and 7.20±0.24 respectively) were all significantly higher in DT2. The feed conversion ratio was higher significantly in DT1. Survival, hepatosomatic index and condition factor were similar between the two treatments. Though the aforementioned body indices indicated that the total replacement of fish meal with maggot meal is not harmful to the fish, a partial replacement may be better for optimum output

Supplemental enzyme in artificial diets with difference doses for African catfish Clarias gariepinus (initial weight of 0.0048±0.0001 g and total length 0.7633±0.0392 cm) were examined for 12 days feeding trial. The aim of this study was to analyze the effectiveness supplemental enzymes in diets for growth performance of catfish larvae. Tubifex sp. (control) and a multi enzyme was included at the level of 0.00 (ME0), 1.00 (ME1) and 2.00 g kg-1 (ME2 diet as a test diets. Each of the four experimental diets was randomly assigned to four plicate groups. Larva was allocated into 150 L aquaria at a density of 1350 larvae per aquarium. Data was analyzed using SPSS 20, followed by Duncan’s test. The result showed that the survival rate and condition factors were no statistical difference between experimental diets and control group. The highest final length, final weight, total food consumption, villi length and enzymes activity  were recorded in the Control (P<0.05) and significantly different with other treatments. Feed efficiency’s control significantly different with other. Harvest size distribution, in the small size group (1-2 cm) did not show significantly different, in the medium size group (2-3 cm) and large size group (3-5 cm) the Tubifex sp. treatment were significantly different from the other treatments (P<0.05) whereas between ME0, ME1 and ME2 treatments were not significantly different. Among the supplemental enzyme in test diets, ME2 can improve weight and total length 6.25% and 13.4%, respectively than ME0 treatment. The results suggested that enzyme supplementation can improve intestinal structure and growth performance of catfish larvae. The supplemental enzyme in diets with doses up to 2 g kg-1 can increase intestinal villi’s length but have not been able to increase fish growth performance as use worm.

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.

<p>Most fish farmers in Malawi culture unimproved fish strains whose growth is slow and mature while still small. Four strains of <em>Oreochromis</em>, namely; selectively-bred/improved <em>O. shiranus</em> (F<sub>8</sub>), two reciprocal F<sub>1</sub> <em>Oreochromis</em> hybrids, and <em>O. karongae</em> as a control (mean weight 2.5 ± 0.7 g) were stocked at a density of 5fish/m<sup>2 </sup>in 9m<sup>2 </sup>hapas replicated three times, and cultured for 90 days at Bunda Fish Farm. Fish were fed twice a day with feed formulated using maize bran and soybean containing 30% crude protein throughout the experimental period. The final mean weights were significantly different (p&lt;0.05) across the treatments whereby; hybrid <em>O. shiranus</em> (male) X <em>O. karongae</em> (female) was 12.09g, hybrid <em>O. shiranus</em> (female) X <em>O. karongae</em> (male) was 9.72g, improved <em>O. shiranus</em> (F<sub>8</sub>) registered 9.23g, and <em>O. karongae</em> was the least with 9.00g. Apparent food conversion ratio was also statistically different (p&lt;0.05) across the treatments whereby; <em>O. karongae</em> was 3.63, hybrid <em>O. shiranus</em> (female) X <em>O. karongae</em> (male) was 3.25, improved <em>O. shiranus</em> (F<sub>8</sub>) was 3.16 and hybrid <em>O. shiranus</em> (male) X <em>O. karongae</em> (female) was lowest with 2.26. There were no significant differences on the water quality parameters across the treatments throughout the experimental period and were within the required ranges for growth and survival of tilapias fish species. The results suggest that <em>Oreochromis</em> hybrids may be suitable candidates for aquaculture in terms of production as they performed better than the improved <em>O. shiranus</em> and the control <em>O. karongae</em>.</p>

The objective of this research was to evaluate the supplementation of turmeric in the diet on antioxidant status and growth performance of African catfish (Clarias gariepinus) in zero water exchange condition. This study used a completely randomized design with 4 treatments and 4 replications. Each treatment consisted of feed supplementation turmeric at dosage of 0; 2.5; 5 or 7.5 g kg-1 diet. One hundred catfish juvenile (5.95±0.05 g) were stocked in intermediate bulk container (IBC) tank (1×1×1 m3) and rearing in zero water exchange condition for 60 days. Catfish were fed at satiation twice a day, in the morning and evening. The results showed that an increase in antioxidant content in catfish fed with the addition of turmeric, which simultaneously also reduced the percentage of liver damage. The parameters of liver damage can be seen from several parameters i.e. pale liver, droplet fat and fat content in the addition of turmeric treatment is lower than without the addition of turmeric. However, catfish fed with the addition of turmeric did not show significant results in terms of growth performances.
