“…Tropical aquaculture development in Bolivia has mostly focused on pond culture of the indigenous omnivorous fish known locally as "tambaqui" (Piaractus brachypomus) and "pacu" (Colossoma macropomum), or their hybrids (Valladao et al 2016;Vega et al 2018). These fish are robust and easy to grow, and are high in essential amino acids, unsaturated fatty acids, iron, and protein (Murthy et al 2015;Petenuci et al 2016). The fish were identified by the FAO as a promising native alternative to tilapia culture in the late 1970s, and its culture has been perfected in Brazil and neighboring countries.…”

New aquaculture systems are emerging in new contexts around the world in part due to aquaculture’s perceived development benefits. However, linkages between aquaculture and food security in these systems are unclear. This study investigated the impact of emerging small-scale, business-oriented fish culture in central Bolivia on the food security and dietary diversity of aquaculture producers (n = 40) and workers (n = 26) in the value chain and compared them to local non-aquaculture farmers (n = 40). Three pathways were investigated: fish consumption, household income, and women’s participation. Food insecurity was widespread and did not vary in a statistically significant way between groups, but a trend toward greater food security amongst aquaculture producers was observed. Dietary diversity was highly homogenous, with the notable exception of high fish consumption amongst producers. Aquaculture was related to higher income, and income has a modest positive effect on food security for aquaculturists and non-aquaculture farmers, but not aquaculture value chain workers. Income did not have an effect on dietary diversity. Women’s involvement in aquaculture was correlated positively to productivity, profitability, and size of operation, while male-only aquaculture was negatively correlated to these. The value chain generated employment, especially for women, but average wages were higher for men. The research provides important insight into aquaculture-food security linkages by showing that the introduction of small-scale business-oriented aquaculture systems can provide nutritious products for regional consumption and can have positive effects on food security but is not sufficient to change local dietary preferences more broadly.

“…There is general agreement that the composition of polyunsaturated ω-3 and ω-6 fatty acids (PUFAs) in fish tissue varies depending on the fish diet and on factors such as the species, gender, age, size, reproductive status, sexual maturity, feed, water temperature, geographic location and season (Almeida et al, 2009;Ramos-Filho et al, 2010;Petenuci et al, 2016). The present results showed that the freshwater fish species contained a substantial amount of PUFAs with carbon chains ranging from C 18 to C 22 , but that Nile tilapia (pond) and silver carp had very low PUFA contents.…”

“…The benefits of ω3 PUFAs for humans are associated with the synthesis of eicosanoids, such as leukotrienes, prostaglandins and thromboxanes (Souza, 2010;Kuda et al, 2018). Another important aspect is the nutritional value of PUFAs in human metabolism, which can be estimated by way of health 'indicators' that are calculated using empirical equations: the atherogenicity (AI) and thrombogenicity (TI) indexes, and the hypocholesterolemic/hypercholesterolemic (H/H), polyunsaturated/saturated (P/S) fatty acids and omega-3/omega-6 (ω-3/ω-6) ratios (Ulbricht & Southgate, 1991;Šimat et al, 2015;Petenuci et al, 2016). These indices are strongly associated with disease prevention and health promotion (Rhee et al, 2017;Cherifi et al, 2018).…”

There is a paucity of information about the chemical composition of commercially important freshwater fish species (Nile tilapia, bighead carp, grass carp, common carp and silver carp) cultivated in the western region of Santa Catarina, Brazil. This study determined the moisture, ash, protein and lipid contents and the fatty acid composition, as well as the nutritional quality of the lipids in fillets of these five freshwater fish species. Moisture was the most prominent fish component (74.7%-81.7%), followed by protein (15.8%-18.8%) and lipids (0.4%-8.2%). Saturated palmitic acid (90-1740 mg/100 g) and monounsaturated oleic acid (70-2260 mg/100 g) were the major fatty acids found in all the fish species. The grass and common carps and Nile tilapia (caged) had high contents of γ-linolenic acid (GLA), with an average of 536 mg/100 g. Bighead carp was the richest source of ω-3 PUFA, mainly eicosapentaenoic (EPA, 400 mg/100 g) and docosahexaenoic (DHA, 620 mg/100 g) acids, and had the highest ω-3/ω-6 ratio of 6.11. The nutritional evaluation of the fatty acid profile indicated that average values were: atherogenicity index (AI) ~0.59, thrombogenicity index (TI) ~0.82, hypocholesterolemic/hypercholesterolemic ratio (H/H ~1.98), polyunsaturated/saturated ratio (P/S) ~0.43 and ω-3/ω-6 ratio ~2.18, values suggesting that the consumption of these freshwater fish species could be of benefit to human health.

In this study, the fatty acid (FA) composition of the Japanese grape (Hovenia dulcis) seed oil (JGSO) was firstly evaluated. It was found that the seed oil is rich in alpha-linolenic acid (LNA), containing approximately 425 mg LNA g -1 of total lipids. A fish diet supplemented with JGSO was prepared and supplied to Nile tilapia to investigate the FA composition of the fillets. For this, Nile tilapia were submitted to two feeding treatments: a control diet with 4.2% of soybean oil, and a diet supplemented with 4.2% of JGSO. The LNA, eicosapentaenoic acid (EPA), and docosahexaenoic acid (DHA) values increased significantly (406, 153 and 126%, respectively) with JGSO in the diet and with an increase in feeding time, while the nutritional quality indexes, n-6/n-3 ratio and index of thrombogenicity, decreased 2.8 and 1.4 times, respectively. Thus, the replacement JGSO in the diet raised the nutritional lipid quality in Nile tilapia.Keywords: fatty acids, omega-3, Oreochromis niloticus, supplementation, LNA IntroductionOmega-3 polyunsaturated fatty acids (n-3 PUFA), especially alpha-linolenic acid (LNA, 18:3n-3), eicosapentaenoic acid (EPA,, and docosahexaenoic acid (DHA,, have been extensively studied and said to be beneficial to human health. [1][2][3] A high ratio of dietary n-6/n-3 (omega-6/omega-3) has been reported around the world, reaching ratios between 15:1 and 20:1, while the recommended value is between 2:1 and 1:1. 4 This imbalance in the n-6/n-3 ratios is the result of an excess intake of omega-6 polyunsaturated fatty acids (n-6 PUFAs) from corn, soybean, and sunflower oils. Furthermore, a high intake of saturated fatty acids (SFA) such as myristic acid (14:0), palmitic acid (16:0), and stearic acid (18:0), may contribute to an increase in the indexes of atherogenicity (IA) and thrombogenicity (IT) 6 and to a reduction in the hypocholesterolemic/hypercholesterolemic fatty acid ratio (HH). 7Around the world, flaxseed, perilla, and chia are known sources of LNA, [8][9][10] while fish and microalgae oils rank among the most important sources of EPA and DHA. 11,12 The Japanese grape is originally from Japan, but has quickly expanded to other countries, such as India, Paraguay, Argentina, and Brazil, due to its easy adaptation to the soil and resistance to cold. 13 The Japanese grape are deciduous trees, growing to 10 to 15 m and reaching 20 to 40 cm in diameter of the trunk, commonly used for ornamental and reforestation purposes, and the wood for production of energy, paper and cellulose. The fruit is a small dry capsule from 6 to 7 mm in diameter containing 2 to 4 seeds, attached to a peduncle, which becomes thickened and fleshy when mature, which is also sweet and pleasant-tasting. The seeds are brown with a circular shape from 4 to 8 mm in diameter.14 The peduncles (pseudofruits) can be consumed in natura or in dehydrated form and are also used for alcoholic fermentation, to produce wine or vinegar. 15,16 According to Bampi et al. 13 the peduncles are rich in sugars and have a high content of dietary fi...
