“…SFA content of freshwater eel oil was 37.99%. Dutta and Dutta 6 examined fatty acid profile of freshwater eel (Monopterus chucia). Predominant fatty acids found in muscle of Monopterus chucia were heptadecanoic acid/C17:0 (35.29%) for its SFA content, palmitoleic acid/C16:1 (11.16%) for its MUFA content, and linoleic acid/C18:2 (2.77%) for its PUFA content.…”

This study aimed to analyze the fatty acid composition of some potential fish oil originated from some production centers in Indonesia. Samples observed were softshell turtle oil, freshwater eel oil, shark liver oil, tuna oil, and lemuru oil. Fatty acid composition of the oil was analyzed and quantified using gas chromatography after being converted into FAME. Detected SFA, MUFA, and PUFA as ranged from 1.67-37.99%, 3.17-38.34%, and 0.70-34.99%. Oleic acid became predominant fatty acid in sofshell turtle oil, freshwater eel oil, and shark liver oil. Tuna oil was rich in DHA (24.56%), while lemuru oil was rich in EPA (14.36%).

“…MUFAs are good storage lipid preferentially used as energy sources and substrates for βoxidation in fish [31] [33]. According to Dutta and Dutta, [55] palmitoleic acid increases insulin sensitivity by suppressing inflammation and inhibits the destruction of pancreatic beta-cells which are known to secrete insulin [55]. High MUFAs recorded in these fish species denotes that they are better sources of energy to both the fish and the consumer.…”

Fish oils are good sources of essential fatty acids beneficial to human health by helping the body in preventing diseases and enhancing proper growth and development. This study is aimed at investigating the quantitative and qualitative composition of fatty acids in two commonly consumed and most abundant freshwater fishes (Clarias gariepinus and Chrysichthyes nigrodigitatus) from the Cross River at Ahaha, Obubra. The oil was converted to fatty acids methyl esters (FAME) and the fatty acids evaluated by gas chromatography – mass spectrometry using retention time method. The fatty acids profiles include saturated fatty acids (SFAs), monounsaturated fatty acids (MUFAs) and polyunsaturated fatty acids (PUFAs). The composition varied from 0.06 – 24.00% of SFAs, 0.23 – 21.40% of MUFAs and 0.23 – 12.22% of PUFAs in the both species. The major SFAs were palmitic (C16:0) and stearic (C18:0) acids while the most abundant MUFA was oleic (C18:1) acid. Dominant PUFAs in the both specie were linoleic (C18:2), eicosapentaenoic (EPA, C20:5) and docosahexaenoic (DHA, C22:6) acids. Quantitatively the composition of various fatty acids was in the order SFAs < MUFAs < PUFAs although not significantly different (p< 0.05) in the species. Chrysichthys nigrodigitatus had higher total fatty acids (TFA), PUFAs and omega –3 / omega –6 ratio than C. gariepinus with higher levels omega -6 fatty acids. The ratios of PUFA/SFA were higher in C. nigrodigitatus although both were greater than the minimum value (0.4) recommended by World Health Organization. The result indicates that the species had high quality essential fatty acids especially DHA and EPA although relatively higher in C. nigrodigitatus. Hence these species have the potentials to serve as the natural dietary supplement for all important omega -3 fatty acids.

“…Fish having energy depots in the form of lipids will rely on this palmitoleic acid. It is a beneficial fatty acid which when consumed increases insulin sensitivity by suppressing inflammation and inhibits the destruction of pancreatic betacells which are known to secrete insulin (Dutta and Dutta, 2013). These existing interspecies variability in the composition of fatty acid of fish lipids (and of the specific PUFA in particular) can be explained by the existence of a large number of external factors (environment, tropic effects) and internal factors (fish species, feeding regime and digestion, life cycle, stage, composition of lipids triglycerols, phospholipids and their topographical origin) (Ashim et al, 2014).…”

; +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...
