“…The transference of this fatty acid from the diet to the fish was 2.5 times higher in Treatment I than in II (Table 4). This effect was expected according to prior studies (Barilli et al, 2014;Carbonera et al, 2014;Higuchi et al, 2013;Nishiyama et al, 2014;Silva et al, 2014a), adding promising sources of LNA (chia, flaxseed and perilla). Another highlighted point was the increase of long and very long chain fatty acids, such as eicosapentaenoic (EPA, 20:5n-3), docosapentaenoic (DPA, 22:5n-3) and docosahexaenoic (DHA, 22:6n-3) acids.…”

The present work aimed at studying the effect of different drying methods applied to tilapia byproducts (heads, viscera and carcasses) fed with flaxseed, verifying the contents of omega-3 fatty acids. Two diets were given to the tilapia: a control and a flaxseed formulation, over the course of 60 days. After this period, they were slaughtered and their byproducts (heads, viscera and carcasses) were collected. These fish parts were analyzed in natura, lyophilized and oven dried. Byproducts from tilapia fed with flaxseed presented docosapentaenoic, eicopentaenoic and docosahexanoic fatty acids as a result of the enzymatic metabolism of the fish. The byproducts from the oven drying process had lower levels of polyunsaturated fatty acids. In the multivariate analysis, the byproducts from fish fed with flaxseed had a greater composition of fatty acids. The addition of flaxseed in fish diets, as well as the utilization of their byproducts, may become a good business strategy. Additionally, the byproducts may be dried to facilitate transport and storage.

The objective of this study was to evaluate growth, body chemical composition and lipid profile of Nile tilapia juvenile fed with Schizochytrium sp. Two hundred and forty Nile tilapia (Oreochromis niloticus) juvenile (1.33 ± 0.11 g) were distributed in 20 aquariums, at the density of 12 fish per aquarium. The juvenile were fed with five levels of Schizochytrium sp.: Control (0 g/kg of Schizochytrium sp. in feed); AS10 (10 g/kg of Schizochytrium sp. in feed); AS20 (20 g/kg of Schizochytrium sp. in feed); AS30 (30 g/kg of Schizochytrium sp. in feed) and AS40 (40 g/kg of Schizochytrium sp. in feed). The inclusion of Schizochytrium sp. increase the body weight, weight gain, final biomass and biomass gain of tilapia juvenile. The body crude protein of tilapia was increased after addition of microalgae. Juvenile lipid profile also was influenced when fed with 40 g of Schizochytrium sp. per kg and have it levels of omega‐3 and docosahexaenoic acid (DHA) increased, and omega 6:3 ratio decreased. Tilapia juvenile fed with Schizochytrium sp. per kg have better growth, omega‐3 and DHA levels rising in the body, being a considerable source of fatty acids for human nutrition. Levels above 20 g of Schizochytrium sp. per kg in the feed favour the increase of protein in Nile tilapia body.

“…Similarly, O. mykiss fed 1% of CLA for 140 days showed a CLA content of only 1.3% in the carcass (Ramos et al, 2008). Oreochromis niloticus fed 1% of CLA for 60 days (Dos Santos et al, 2011) and Piaractus mesopotamicus fed 1% of CLA for 49 days (Barilli et al, 2014) had similar CLA incorporation in the filet when compared with A. altiparanae (3.3 and 2.0% of CLA, respectively). In addition to species, other factors such as diet supplementation, feeding time, ingredient composition, and the proportion of CLA isomers in the diet may also affect CLA incorporation in animal tissues (Azain, 2003).…”

The effects of feeding diets with conjugated linoleic acid (CLA) to Astyanax altiparanae for different periods were investigated on carcasses’ fatty acid profile and nutritional quality. The trial was laid out in a complete randomized design with eight feeding periods (0, 7, 14, 21, 28, 35, 42, and 49 days) and four replicates. A total of 240 fish (3.4 ± 0.3 g) were distributed into four aquariums and fed with the diet containing 32% crude protein, 15 MJ kg-1 gross energy, and 2.5% of CLA. Feeding CLA diet for 49 days resulted in the higher deposition of CLA, CLA isomers, and docosahexaenoic acid (DHA). The isomer c9,t11 was highly deposited than the t10,c12. Polyunsaturated fatty acids (PUFA), n-3, and n-6 increased with feeding period, whereas saturated (SFA), monounsaturated, and medium-chain fatty acids decreased. PUFA/SFA ratio, DHA/EPA, EPA+DHA, and thrombogenicity index increased linearly. Whereas atherogenicity index reduced, hypocholesterolemic/hypercholesterolemic ratio increased in quadratic effects over feeding time. No difference was observed for the n-6/n-3 ratio. Feeding A. altiparanae with 2.5% of CLA for a minimum of 35 days improves the fatty acid profile and provides a commercial product with good nutritional quality and functional benefits.

One hundred and eighty freshwater fish, Surubim-do-Iguaçu, were distributed into three cages and fed for 25 and 50 days with control diet based on soybean oil and diet supplemented with linseed oil, rich in fatty acid 18:3n-3. The objective this work was to evaluate the incorporation of 18: 3n-3 acid during the experiment. Total lipids were extracted and fatty acids were separated in the gas chromatograph coupled to a flame ionization detector and quantified. The fish that were fed during 50 days diet supplemented with flaxseed oil, incorporated alpha-linolenic acid on your filet, increasing the amount of this fatty acid of 9.76 mg g -1 to time zero to 20.64 mg g LT -1. The best reason n-6/n-3 was found in fillets with 50 days containing flaxseed, 4.45. Thus, it is concluded that the addition of linseed oil rations brings development and improved fatty acid profile in "Surubim do Iguaçu" fillets.Keywords: Linseed oil; omega 3 fatty acid; incorporation. ResumoCento e oitenta peixes de água doce, Surubim-do-Iguaçu, foram distribuídos em três tanquesrede e alimentados durante 25 e 50 dias com ração controle, à base de óleo de soja, e ração suplementada com óleo de linhaça, rico em ácido graxo 18:3n-3. O objetivo deste trabalho foi avaliar a incorporação de ácido 18:3n-3 no decorrer do experimento. Os lipídios totais foram extraídos e seus ácidos graxos separados em cromatógrafo à gás acoplado a detector de ionização em chama e quantificados. Os peixes alimentados com ração suplementada com óleo de linhaça incorporaram ácido alfa-linolênico em seu filé, aumentando a quantidade desse ácido graxo após 50 dias de alimentação, de 9,76 mg.g -1 no tempo zero para 20,64 mg.g -1de LT no final no experimento. A melhor razão n-6/n-3 encontrada foi nos filés com 50 dias e alimentação com linhaça, 4,45. Assim, conclui-se que a adição de óleo de linhaça as rações traz incorporação e melhoria no perfil de ácidos graxos em filés de Surubim do Iguaçu.Palavras-chave: Óleo de linhaça; ácidos graxos ômega 3; incorporação.
