The evaluation of nutrient composition in adult Chrysichthys nigrodigitatus (CN), Clarias gariepinus (CG) and Heterobranchus bidorsalis (HB) was determined on wet basis. A total of 60 samples (weight: 500g-1kg fish) comprising 20 of each species were gutted, washed, ground and analyzed for moisture, protein, fat, ash and carbohydrate, using standard methods. Results showed the mean values for moisture, protein and fat as 72.53+ 0.23 (CG)-80.73+ 0.23% (HB), 18.20+ 0.13(HB)-21.37+ 0.13% (CN) and 2.13+ 0.10 (CN)-7.25 + 0.10% (CG). The carbohydrate and ash values ranged 1.33+ 0.19 (HB)-2.55+ 0.19% (CG) and 1.63+ 0.09 (HB)-3.30+ 0.09% (CN). The caloric values for protein was 13.27+ 0.14 (CN)-17.22+ 0.14 Kcal/100g (CG), fat showed 27.26+ 0.19 (CN)-57.31+ 0.19 Kcal/100g (CG) and carbohydrate 1.17+ 0.34 (HB)-1.35+ 0.34 Kcal/100g (CN). The nutrients showed significant differences at p< 0.001 between the fishes examined. These catfishes were observed to contain adequate quality animal protein, fat and ash that would provide appreciable amounts of essential nutrients such as amino acids, fatty acids, minerals and energy to support human health.

“…Ujjania et al [27] opined that condition factor greater or equal to one is good, indicating a good level of feeding, and proper environmental condition. Mean K-values gotten from this study (0.88) were less than one (1), hence revealing that the species fell slightly from being unhealthy. This support the report of Getso et al [28] who worked on the Length-Weight Relationship and Condition factor of C. gariepinus and O. niloticus of Wudil River, Kano, Nigeria, and obtained condition factor less than one (1).…”

The silver catfish Chrysichthys nigrodigitatus is of economic importance in sub-sahara Africa. In Ogbese town, and its environs, it constitutes a means of income and food for fisherfolks and community members. Hence, this study was undertaken to assess health status of Chrysichthys nigrodigitatus using haematology and histological assessment of the fish specie due to the anthropogenic activities that takes place around the river body. A total 120 live juvenile fish samples of C. nigrodigitatus were collected around shallow habitats of Ogbese River by the assistance of fisherfolks using fish cage. Some water parameters measurements were taken: temperature, pH, DO, Turbidity and Conductivity. Morphometric measurement: Weight (g) and length (cm) of fish were taken. Haematology and histology of fish gills, liver and intestine were determined. Mean water temperature (27.70±0.18°C), pH (7.36±0.22), DO (6.98±0.15 mg/l), Turbidity (78.50±13.53 NTU) and Conductivity (148.35±27.98) of the river determined respectively. Mean body weight of fish was 148.15 ± 36.53 g, and mean length was 25.64 ± 2.86 cm. The gills, liver and intestines of the fish specie were examined to assess the architecture of the organs. Results of haematology studies of C. nigrodigitatus revealed high values in the parameters measured. Red Blood Cell was higher than the White Blood Cell with mean value of (225.63±10.45 103/mm3) while Eosinophils recorded lowest parameters with mean value of (1.75±0.52%). Results of histology of gills, liver and intestines showed that the gill filaments were eroded with deformation of the cartilage core and also hyperplasia of the secondary lamellae. The intestines showed atrophy in a mucosal layer, hemorrhage and dilation within blood vessels and within serosa of mucosa and for liver, picnotic nucleus were shattered, the hepatocytes were ruptured and there was increased kupffer cell count as a result of exposure to pollutants. The results indicated that pollution level of the environment have significant impact on health status of fish.

“…Fish oil is one of the most important animal lipids and other vital nutrients' sources that are widely consumed by all races and classes of people (Abolude and Abdullahi, 2005). Lipids from fish are well known as a rich source of long-chain n-3 polyunsaturated fatty acids (LC n-3 PUFA) such as eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) which cannot be synthesized by humans which are commonly obtained from the diet (Alasalvar et al, 2002).…”

; +2348064398527 1.1 INTRODUCTION Catfishes (Family: Clariidae) are a large group of predominantly freshwater fishes of high economic importance in many countries of the world especially African and Asian continents (Olaniyi and Omitogun, 2014); and also serve mainly as food in many homes and hotels (Omitogun et al., 2012). They also occur in the large rivers such as the Amazon and Zaire (Bruton, 1988). The family Clariidae is divided into two genuses, namely Clarias and Heterobranchus. Madu et al. (1999) reported that two species of Clarias are most popular for fish farming in Nigeria. These are C. anguillaris and C. gariepinus similarly, only two species of Heterobranchus (H. bidorsalis and H. longifilis) are commonly available (Madu et al., 1999). Recently, there has been an increase in the farming of Catfishes especially Clarias and Heterobranchus species and their hybrids in Nigeria based on their growth performance, short generation interval, and consumer preference or demand, due to their good taste, good flavour, among others (Agbo, 2015; Olaniyi et al., 2017). Consequently, there is a high demand for these catfish seeds by fish farmers for stocking (Olaniyi et al., 2017). Clarias has a single rayed dorsal fin extending almost to the tail and four pairs of barbels on their flattened, strongly depressed head (Reed et al., 1967). The rayed dorsal fin is continuous, extending to the base of the caudal peduncle. C. gariepinus (Fig. 1) has vomer teeth located at the upper jaw which are mostly conical or granular-sub-conical forming a ABSTRACT Catfishes are freshwater fishes of high economic importance in many countries of the world due to their rich source of lipids, protein and other vital nutrients. The present investigation characterizes lipids from two species; Heterobranchus longifillis and Clarias gariepinus of catfishes from Otuocha River, Anambra State, Nigeria. The oils were extracted using soxhlet apparatus and the oil were qualitatively characterized using the standard methods of AOAC and AOCS. The fatty acid profile of the oils were determined using gas chromatography. The results showed that H. longifillis had the highest oil composition of 15.33±0.28 % per 100 g DW followed by C. gariepinus (14.83±1.61 % per 100 g DW). The peroxide values of oil extracted from H. longifilis was 5.33±1.51 meq/kg and C. gariepinus, 3.34±1.51 meq/kg; the acid values for oil extracted from H. longifilis was 2.03 ± 0.23 mgKOH/g and C. gariepinus, 1.89±0.13 mgKOH/g. p-anisidine values of 15.38±0.20 and 13.57±0.0.28 were obtained for H. longifilis and C. gariepinus oils respectively while the TOTOX values are 6.12 ± 0.51 and 20.99±1.08 respectively. Fatty acid profile analysis showed that lauric (12:0), miristric (14:0), palmitic (16:0), stearic (18:0), oleic (18:1), linoleic (18:9,12), and linolenic acids (18:6,9,12) were dominant in the oils of these fishes. This study has revealed that the qualitative parameters of the extracted oils are within the recommended range by FAO. By having the lowest n-6 PUFA and best qual...
