“…TG was the predominant component found in the selected Indian fresh water fish and constituted more than 80% of total lipids . Steelhead trout viscera comprised TG (74.1% of total lipid) as the major constituent . Similar result was reported for Alaska pollock viscera, where TG accounted for 72.14% of total visceral lipid .…”

Lipids from Asian seabass visceral depot fat (SVDF) were extracted using different methods including heating in air, heating under vacuum, autoclave, and solvent extraction. Lipid extracted by heating under vacuum had the highest yield (67.33%) (p < 0.05). All extracted lipids had triglyceride (TG) as the major component, followed by phospholipid (PL). Oleic acid (C18:1 n‐9) constituted as the most abundant fatty acid in all lipids, followed by palmitic acid (C16:0) and linoleic acid (C18:2 n‐6), regardless of extraction methods. Docosahexaenoic acid (C22:6 n‐3) and eicosapentaenoic acid (C20:5 n‐3) accounted for 6.88–7.41 and 1.76–2.51%, respectively. During storage of 30 days at 30°C, lipids extracted by heating under vacuum or by solvent had the higher oxidative stability as indicated by the lower peroxide value (PV), thiobarbituric acid reactive substances (TBARS), conjugated diene (CD), and ρ‐anisidine value (AnV). Lower increases in free fatty acid (FFA) content were also found in the samples obtained by those two methods. Extraction of lipid by heating under vacuum or solvent could lower the formation of volatile lipid oxidation products. Thus, extraction method had the profound impact on yield and storage stability of lipids from SVDF. Practical applications: Asian seabass visceral depot fat is considered as the byproduct during butchering process. This fatty tissue can serve as the potential raw material for lipid production. Several methods have been used for extraction of lipids, in which yield and chemical compositions can be varied. Therefore, the appropriate extraction method should be implemented to increase the efficacy of lipid extraction and to obtain lipid with high quality and oxidative stability. As a consequence, Asian seabass viscera can be better exploited and fish lipid rich in n‐3 fatty acids can be produced and used as nutraceutical or supplement. Lipids from Asian seabass visceral depot fat are extracted using different methods including heating in air, heating under vacuum, autoclave, and solvent extraction. Extraction by heating under vacuum rendered the lipid with the highest yield and the oxidation occurred at the low extent. During storage of 30 days at 30°C, lipids extracted by heating under vacuum also have the high oxidative stability. Therefore, Asian seabass viscera could be the potential raw material of lipid rich in n‐3 fatty acids, which can be extracted and used as nutraceutical or supplement.

“…Twenty nine fatty acids were obtained from the oil of C. gariepinus in the present study. Thirteen fatty acids were identified from n the skin of C. gariepinus oil by Sayem et al [32] and 20 fatty acids from its viscera by Effiong and Fakunle [33] obtained twenty. The fatty acids reported in the three studies were Lauric acid (C12:0), Pentadecenoic acid (C15:0), Capric acid (C10:0), Undecanoic (C11:0), Dodecanoic acid (C12:0), Palmitoleic acid.…”

It was found that Linoleic acid (Effiong and Fakunle) [33] and Oleic acid (Goyens et al,) [34] . are highly required by human body to maintain good health status Both acids are not produced by the human body and can be assimilated from fish as food (Kolanowski and Laufenberg [2] ; Sayem et al [32] found that the total proportions of polyunsaturated fatty acids were higher in pure cultured catfish than wild ones.…”

Wild and hatchery fingerlings of Clarias gariepinus were cultured in recirculated aquaculture system. They were fed five diets composed of fish meal: poultry by-product meal at a ratio of 100:0%, 75:25%, 50:50%, 25:75% and 0:100%, respectively. The gross chemical composition showed no significant differences in the flesh of wild and hatchery fingerlings in composition, except that the fat content of 25:75% diet was significantly higher (p<0.01) in the wild fingerlings. The highest calorific values was shown by wild fingerlings given 25:75% diet .The lowest fat to protein ratio was obtained by fingerlings fed 75:25% diet. The 29 fatty acid obtained from the oil of C. gariepinus included 15 saturated fatty acids, 7 monounsaturated and 7Polyunsaturated fatty acids.

“…Fish oils are majorly composed of natural bioactive lipids which are commercially used in pharmaceutical and food industries [1]. Fish oil remains the most valuable oil due to its quality and the various health benefits [2]. Fish oil contains majorly polyunsaturated fatty acids and essential fatty acids that cannot be synthesized by the body but can be obtained through diet.…”

Oil composition of Clarias gariepinus collected from various locations were studied and compared. Oils contained in the fishes were extracted using Soxhlet extraction method. The physiochemical properties of the oils were determined using official methods of analysis while the fatty acid composition was analysed using Gas Chromatography- Mass Spectrophotometer. The functional groups present in the oils were also detected using Fourier Transform Infra-red Spectroscopy (FTIR). The oil content for the fishes was in the range of 30.65%-40.57%. The oil extracted from C. gariepinus collected from Badagry lagoon had the highest peroxide and iodine values (5.12 mg KOH/g and 129 mgI2/100 g). The fatty acid composition shows that the oils contains large number of essential polyunsaturated fatty acids except for the oil extracted from C. gariepinus collected from Ikorodu lagoon that contains large number of monounsaturated fatty acids. The FTIR spectra show the presence of carboxylic acid, methylene, esters, ketone and alcohol functional group. It was deduced from this study that habitat had strong impact on the oil composition of C. gariepinus.
