Physical Features

Background: Fish is known to be one of the cheapest sources of animal protein and have essential nutrients needed in human diets. The present study investigated the proximate and nutrient composition of three species of fish, Champsocephalus gunnari, Oreochromis niloticus, and hybrid catfish (Clarias gariepinus). Methods: The sample collection, proximate and mineral analysis were conducted using the standard protocols of sample collections and chemical analysis. Results: The results revealed that Champsocephalus gunnari, Oreochromis niloticus, and Clarias gariepinus contain moisture (66.00±0.50%, 52.00±1.00%, and 70.00±0.20%), crude protein (9.20±0.1323%, 3.75±0.02%and 5.80±0.05%), crude lipid (10.16±0.91%, 2.37±0.01% and 12.00±0.30%), ash (11.92 ±0.02%, 39.40±0.03% and 11.97±0.06%), and crude fiber (2.03±0.01%, 2.36±0.02% and 0.19±0.01%) respectively. The mineral contents were: iron (4.50±0.01mg/kg, 3.70±0.01 mg/kg and 4.70±0.02mg/kg), Zinc (2.35±0.01mg/kg, 2.15±0.0100mg/kg and (1.89±0.01mg/kg) for Champsocephalus gunnari, Oreochromis niloticus, and Clarias gariepinus respectively, while copper was only detected in C. gunnari (0.25±0.01mg/kg). The same amount of chromium (0.01±0.00 mg/kg) was detected in all the samples. Manganese was undetected in all the samples. Conclusion: In conclusion, the present study demonstrated the nutritional value of Champsocephalus gunnari, Oreochromis niloticus and Clarias gariepinus. This information would help in choosing any of the fish bases on their nutritional values rather than taste and other physical features.

Nile Tilapia Oreochromis Niloticus

Commonly utilized feed ingredients for culture of Nile tilapia ( Oreochromis niloticus ) and Africa n catfish ( Clarias gariepinus ) from Kenya , Tanzania and Rwanda were collected over a period of six months (January - June 2010) and evaluated for their nutritive composition through proximate analysis. Most of the fish feed ingredients were found in all the three countries except a few that were unique to one or two countries as detailed in the results . Feed ingredients of animal origin exhibited significantly (P <0.05) higher crude protein levels (407 - 635 g/kg DM ) compared to the feed ingredients of plant based origin . Freshwater shrimp s ( Caridina nilotic a ) contained the highest crude protein levels of 635 g/kg DM. Feed ingredients of animal origin had low ether extracts (EE) with an exception of Omena fish ( Rastrineobola argentea ) . Crude fibre (CF) was generally higher on feed ingredients of plant origin and ranged between 55 - 368 g/kg DM while Nitrogen Free Extract s (Nf E) and ash content were higher in the feedstuff s of plant origin with an exception of maize bran which had the lowest value. Omena fish and freshwater shrimp had higher ash content of 182 and 228 g/kg DM compared to other feed ingredients of animal origin, which may indicate contamination with soil particles during drying process . Based on the feed ingredient availability, potential competition with other human uses, content of crude protein and crude fibre and the feasibility of removal of anti -nutritional factors, C . nilotica , blood meal, meat and bone meal , were identified as most promising sources of animal based protein. Cotton (Gossypium spp) and sunflower ( Helianthus annuus ) seed cakes provided the best option as source of processed plant based protein. L eaves of gallant soldier ( Galiso nga parviflora ) , sweet potato ( Ipomoea batatus ), cassava ( Manihot esculenta ) and papaya ( Papaya carica ) were identified as high potential feedstuffs of plant origin either processed or in raw form for small -scale fish farming . We recommend that in well fertilized semi- intensive ponds , maize ( Zea mays ) , wheat ( Triticum aestivum ) and rice ( Oryza sativa ) bran may be utilized where available to supplement natural pond food

Acacia Albida

The present study was conducted to find out the nutritional values of Faidherbia albida (Acacia albida) seeds and pulp to be used as components in livestock feeds. The samples were randomly collected from various trees during the period of January to February. The samples were separated, milled and analysed for proximate components and mineral elements using standard methods of the AOAC. Proximate analysis results showed that the concentrations of tested parameters in the seed and the pulp respectively on % dry matter were: dry matter (90.0 + 0.4; 93.3 + 0.2), ash (3.3 + 0.1; 6.7 + 0.1), crude protein (20.6 + 1.2; 19.5 + 0.4), crude lipid (13.3 + 0.1; 3.3 + 0.1), crude fibre (6.7 + 0.1; 13.3 + 0.2), and available carbohydrate (46.1 + 0.1; 50.53 + 0.7). The results indicated that the contents of dry matter, ash, crude fibre and available carbohydrate were significantly higher (p < 0.05) in the pulp compared to the seed while the crude lipid values, however, were significantly higher (p < 0.05) in seeds compared to pulp. Crude protein values did not differ significantly (p > 0.05) between treatment means of seeds and pulp. The estimated energy value was significantly higher (p < 0.05) in the seed (1,682 kJ/100g) compared to pulp (1,363kJ/100g). The results for the mineral analysis indicate that the seeds and pulp contain appreciable concentrations (mg/100g) of Ca (136.6 + 5.0; 55.0 + 5.0); Mg (135.0 + 2.0 + 5.0; 84.7 + 3.0); P (26.6 + 0.9; 29.6 + 0.7); K (144.5 + 0.2; 88.8 + 0.1); Na (12.5 + 0.1; 6.8 + 0.1); Fe (6.2 + 0.2; 8.8 + 0.3); Cu (5.8 + 0.1; 2.5 + 0.1) and Zn (8.0 + 0.1; 3.0 + 0.1). Mineral elements in seed are significantly higher (p < 0.05) compared to that of pulp in most cases. From the results it can be inferred that the seed and pulp of F. albida could be an important source of feed ingredient for livestock if properly harnessed.

Objective: To study the incidence and seasonal dynamics of different fungi affected freshwater fishes in Lake Manzala with molecular identification of the isolated fungi. Animals: 300 Nile tilapia (Oreochromis niloticus) and 300 catfish (Clarias gariepinus). Design: Descriptive study. Procedures: Random samples of Oreochromis niloticus (O. niloticus) and Clarias gariepinus (C. gariepinus) were collected from Manzala fish farms. Clinical and postmortem examination of fish was applied. Isolation and identification of different fungi were performed by conventional methods. Furthermore, the molecular characterization of isolated fungi was carried out. Results: C. gariepinus had a higher rate of infection with different fungal species than O. niloticus. Aspergillus spp. (Aspergillus niger and Aspergillus flavus) were the most fungal isolated from the examined fishes, followed by Penicillium spp. and Candida albicans. Aspergillus spp were detected in all seasons with a higher rate in summer and spring. A. flavus, A. niger, Penicillium spp. and C.albicans isolates were amplified from both C. gariepinus and O. niloticus at the specified molecular weight using PCR. Conclusion and clinical relevance: Fungal infection affected the fish showing different external and internal lesions, all species of Aspergillus were found in all seasons with a high rate in, hot seasons, summer and spring. The Prevalence of Penicillium and C. albicans were also reported. All fungal isolates were identified on the phenotypic and molecular bases.

Wet And Dry Seasons

Smoke-drying Clarias gariepinus (catfish) provides animal protein and a source of livelihood in Lagos, Nigeria. Changes occurring to seasonal and mineral compositions of smoke-dried catfish using local Traditional Drum Kiln (TDK) and a newly constructed Eco-Friendly Kiln (EFK) fitted with a flame, drying and electronic components was carried out in this study. The smoke-drying process was carried out in both wet and dry seasons and smoke-dried catfish samples stored at ambient and adjusted refrigerated temperatures of 28 and 4 0C. The smoke-drying procedure was  standardized at 60 - 80 0C and kiln lasted 24 ± 3 hours. Moisture content results showed a significant difference when the catfish samples were smoke-dried using TDK and EFK and stored in ambient and controlled temperatures in both wet and dry seasons while crude protein, lipid, ash and crude fibre values were significantly different when stored only in dry season. Mineral elements phosphorus, sodium, copper, magnesium and iron showed a significant difference when stored at both temperatures and seasons using both kilns. Mineral elements were found to be most stable in smoke-dried catfish samples when stored at controlled temperatures. This work proved that standardizing smoke-drying process using both kilns resulted in good quality smoke-dried catfish but showed that higher biochemical values were obtained when EFK is used.

Western Cameroon is one of the regions most in needs of innovative and healthy solutions for freshwater fish conservation. This study aimed at evaluating the socio-economical characteristics of fish smokers and technical factors on the species smoked in the Noun Division. A total of 91 fish smokers were chosen. The socio-economic data were on age, gender, religion, number of dependents, marital status, ethnic group, education level, economic activities, smoking goals and workforce. The results of this study showed that fish smoking is practiced mainly by women (70%) which is common in Sub Sahara Africa small scale fish sector. The smokers are aged from 20 to 50 years (80%), married (92.2%) and taking care of a family of 1 to 10 persons (80%). These smokers are Muslim (74%), belonging to the Bamoun ethnic group (81%). They were also involved in other activities: agriculture (29%) and trade (1%). About 67% of the sampled smokers’ population had an experience of more than 10 years in the domain. The Purpose of smoking was largely sales (97%) and subsistence (3%). Nile tilapia (Oreochromis niloticus) was the most smoked species (36%), followed by African catfish (Clarias gariepinus) with a proportion of 32%. The average quantity of fresh fish smoked was 110 kg/day/smoker, with Oreochromis niloticus being more produced (60±4.74 kg/day/smoker). With regard to the smoking techniques used, hygiene measures were poorly respected. The major constraints revealed by the survey were that freshwater’s traditional fish smoking activities in Noun Division are influenced by gender, economic and cultural background. There is a lack of technical support material and financial means. Any implications for future investigations on health and food safety will be suitable for fresh fish smokers and the entire consumers.

Accumulation of heavy metals in fish is considered a critical problem for human health. Therefore, the study aimed to quantify the concentrations of iron (Fe), zinc (Zn), manganese (Mn), and lead (Pb) in Oreochromis niloticus and Clarias gariepinus from two areas in Al Sharqia governorate, Egypt, from September 2017 to August 2018. A human health risk assessment was conducted to evaluate the potential hazards associated with fish consumption. Metals concentrations (mg/kg dry weight) in muscles of catfish ranged 1.88-221.26 for Fe; 1.78-19.77 for Zn; BDL-238.51 for Mn; BDL-22.75 for Pb. In muscles of tilapia fish metals concentrations ranged 7.96-149.10 for Fe; 1.20-19.77 for Zn; BDL-230.82 for Mn; BDL-25.93 for Pb. Pb had Hazard quotients (HQs) which indicated potential health risks to tilapia consumers at both study areas and catfish consumers at the Faqous area. Fishermen were at higher risk compared to the other consumers.

The effects of various processing methods on the proximate composition and dieting ofAmaranthus hybridusandAmaranthus cruentusfrom West Cameroon were investigated in this study. Both amaranths leaves were subjected to same treatments (sun-dried and unsliced, sliced and cooked), milled, and analysed for their mineral and proximate composition. Thirty-SixWistaralbino rats of 21 to 24 days old were distributed in six groups and fed for 14 days with 10% protein based diets named D0 (protein-free diet), DI (egg white as reference protein), DII (sun-dried and unslicedA. hybridus), DIII (cooked and slicedA. hybridus), DIV (sun-dried and unslicedA. cruentus), and DV (cooked and slicedA. cruentus). The protein bioavailability and haematological and biochemical parameters were assessed in rats. The results showed that K, P, Mg, Zn, and Fe had the higher content in both samples regardless of processing method. The sun-dried and unslicedA. cruentuscontained the highest value of crude protein 32.22 g/100 g DM (dry matter) while the highest crude lipid, 3.80 and 2.58%, was observed, respectively, in sun-dried and unslicedA. hybridusand cooked and slicedA. cruentus. Cooked and slicedA. hybridusandA. cruentuscontained high crude fiber of 14 and 12.18%, respectively. Rats fed with diet DIII revealed the best protein bioavailability and haematological parameters whereas 100% mortality rate was recorded with group fed with diet DIV. From this study, it is evident that cooked and slicedA. hybridusandA. cruentuscould play a role in weight reduction regimes.
