“…Total n-3 content was higher in many farm-raised fillets than wild-caught fillets, but the difference was not as dramatic as it was with other fatty acids. This is most likely due to the higher costs associated with diets high in n-3 fatty acids, which are derived from fish oils [41,42]. Because of the additional costs associated with diets high in n-3 fatty acids, they are often incorporated into the diet late in the lifetime of farmed fish [43].…”

“…For wild-caught species, the diet is determined by changes in environmental conditions, while the composition of farmed species is dependent upon the amount and composition of the feed [32]. In order to control costs, diets high in inexpensive and readily available fatty acids, like SFA, MUFA, and n-6 obtained from plant or animal sources, are often used in aquaculture [41,42]. Although the fillets analyzed in this study were obtained from Trout,Rainbow (1,9;8,20) Bass, Striped (5, [31] is also shown.…”

Fillets of 76 finfish species (293 composites of three fish) were obtained from commercial seafood vendors in six regions of the United States (i.e., Great Lakes, Mid-Atlantic, New England, Northwest, Southeast, and Southwest). Full fatty acid profiles were determined for each species and are presented here. Eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) have been associated with many health benefits. Thus, fillets of each species were compared for total EPA plus DHA content, which ranged from 17 mg/100 g (pangasius/swai) to 2430 mg/100 g (Chilean sea bass). Of the top ten most popularly consumed seafoods in the US, finfish, including salmon species (717-1533 mg/100 g), Alaskan pollock (236 mg/100 g), tilapia (76 mg/100 g), channel catfish (44 mg/100 g), Atlantic cod (253 mg/100 g), and pangasius/swai (17 mg/100 g), exhibited a wide concentration range of EPA plus DHA. Large variances were found within many of the farmed species analyzed, which likely stems from dietary differences in the farm-fed diet. The results of this study provide current information on a broad range of species and will help nutritionists and the public make informed decisions regarding seafood consumption.

“…The lowering of linolenic acid in fish muscle lipids compared to initial might be due to the low amounts of this fatty acid in trial diets. Indeed, the fatty acids of muscle lipids in African catfish reflected the fatty acid profile of the dietary oil that was fed (Ng et al 2003;Babalola et al 2011).…”

“…Moreover, fish feed alone account for between 60 and 75% of the total cost of fish production (Babalola 2010). Thus, aquaculture production can be profitable only if the operators have access to balanced food at competitive prices (FAO 2016) by using locally available inputs.…”

Preliminary use of cashew kernel oil in Clarias gariepinus fingerlings diet: comparison with fish oil and palm oil

et al. 2017

The present study was performed to investigate the effect of fish oil (FO), palm oil (PO), and cashew kernel oil (CKO) as the dietary lipid sources on the growth performance, tissues fatty acids composition and economical profitability in Clarias gariepinus fingerlings. Three isonitrogenous (49.32%), isolipidic (15.18%), and isoenergetic (21 kJ/g) diets were formulated, differed only to the added lipid source and coded accordingly as D1 (fish oil), D2 (palm oil), and D3 (cashew kernel oil). Catfish fingerlings (initial body weight = 2.43 ± 0.04 g) were stocked at 1 fish/L and fed to trial diets at 5.6%. At the end of 8 weeks, C. gariepinus fingerlings fed with D1 and D3 had significantly identical growth and feed utilization efficiency. Those fed with D2 exhibited significantly and numerically low growth performance compared, respectively, to D1 and D3. Contrary to whole-body composition of fish, the muscle lipids fatty acids composition was influenced by the fatty acids profile of the dietary lipid sources. High net profit value (NPV) of 24.59$, high investment cost analysis (ICA) of 10.14$ and low benefit: cost ratio (BCR) of 2.42 were observed in fish fed with D1 while those fed with D3 allowed to have high NPV (23.15$), low ICA (7.86$) and high BCR (2.95). Like others vegetable oils, cashew kernel oil can replace expensive fish oil in C. gariepinus fingerlings diet without negatively affecting its growth performances.

“…Fish oil is an excellent lipid source in commercial aquaculture feeds for provision of energy and essential fatty acid (EFA) (Babalola, Apata, Omotosho, & Adebayo, ; Seyedvali et al., ). However, due to its high cost, limited supply and high risk of oxidation, many researchers have dedicated to examine the substitution of fish oil with vegetable oils in the past decades (Babalola et al., ; Dosanjh, Higgs, Plotnikoff, Markert, & Buckley, ; Francis, Turchini, Jones, & De Silva, ; Rosenlund, Obach, Sandberg, Standal, & Tveit, ). Dietary oil is known as a concentrated and highly digestible source of energy and also supplies animals with EFA for normal growth and development.…”

UntargetedGC‐MSmetabolomics reveals metabolic differences in the Chinese mitten‐hand crab (Eriocheir sinensis) fed with dietary palm oil or olive oil

Palm oil (PO) and olive oil (OO) have been widely used in animal diets, but the knowledge of metabolic change in animals fed a diet with different oil sources is limited. Here, we compared the metabolic differences in the Chinese mitten crab fed with PO and OO as the main dietary lipid sources by performing GC‐MS‐based serum metabolomics assays and traditional nutritional assessments. The crab fed OO displayed lower lipid accumulation and oxidative stress in the hepatopancreas than those in the crab fed PO. In the metabolomics assay, 68 metabolites with high credibility were identified and five metabolites were significantly different between two feeding groups. In these five metabolites, hydroxylamine, 3‐hydroxypropionic acid and 2‐hydroxypyridine were higher in the OO group, while lysine and citrulline were higher in the PO group. We demonstrate that olive oil can provide comprehensive benefits to the crab by providing more energy, improving cell membrane structure, containing phenols as a natural antioxidant, and improving the composition of intestinal microbiota. On the contrary, palmitic acid‐enriched palm oil tended to increase protein degradation and lipid accumulation‐induced lipotoxicity. This study illustrates that the metabolic mechanism differs between crabs fed olive oil and palm oil, and OA‐enriched olive oil is recommended as an ingredient for crab diet formulation.
