ABSTRACT. This study aimed to determine the fatty acid composition and nutritional quality indexes of total lipids in adipose tissue from the orbital cavity of Nile tilapia from continental aquaculture in Paraiba State, Brazil. The tilapias were captured in six fish farms, and after slaughtering and bleeding, the adipose tissue from the orbital cavity was reserved, frozen and lyophilized for analysis of fatty acid composition by gas chromatography. By decreasing order, oleic, palmitic, linoleic, stearic, and palmitoleic acids were the most abundant ones. Monounsaturated fatty acids were the most prominent group in orbital cavity adipose tissue, where as polyunsaturated fatty acids were most abundant in the diet, with a percentage of linolenic acid ranging from 32.99 to 37.57%. Nutritional quality indexes of lipids varied from 0.491 to 0.575 for Atherogenicity Index, 0.543 to 0.741 for Thrombogenicity Index, and from 1.918 to 2.176 regarding the ratio of hypocholesterolemic/hypercholesterolemic. According to the composition of fatty acids and the nutritional quality of total lipids, the use of this byproduct can be recommended for human consumption or to elaborate products for animal intake.Keywords: fatty acids, atherogenicity index, thrombogenicity index, Oreochromis niloticus.Qualidade nutricional dos lipídios totais no tecido adiposo da cavidade ocular da tilápia do Nilo da aquicultura continental RESUMO. O objetivo deste estudo foi determinar a composição dos ácidos graxos e os índices de qualidade nutricional dos lipídios totais no tecido adiposo da tilápia do Nilo da aquicultura continental do Estado da Paraíba, Brasil. As tilápias foram capturadas em seis pisciculturas. Após o abate e sangria, o tecido adiposo da cavidade ocular foi reservado, congelado e liofilizado para análise da composição de ácidos graxos por cromatografia gasosa. Os ácidos graxos majoritários detectados em ordem decrescente foram: ácido oleico, ácido palmítico, ácido linoleico, ácido esteárico e ácido palmitoleico. O grupo mais abundante no tecido adiposo da cavidade ocular foi o dos ácidos graxos monoinsaturados, enquanto que na ração o grupo mais abundante foi o grupo dos ácidos graxos poli-insaturados, com percentual do ácido linolênico variando entre 32,99 e 37,57%. Os índices de qualidade nutricional dos lipídios variaram de 0,491 a 0,575 para o Índice de Aterogenicidade, 0,543 a 0,741 para o Índice de Trombogenicidade; e 1,918 até 2,176 para a razão entre hipocolesterolêmicos / hipercolesterolêmicos. De acordo com a composição dos ácidos graxos e a qualidade nutricional dos lipídios totais, é possível recomendar o uso deste subproduto para o consumo humano ou elaborar produtos para consumo animal.Palavras-chave: ácidos graxos, índice de aterogenicidade, índice de trombogenicidade, Oreochromis niloticus.

“…The literature reports that all fish incorporate EPA and DHA, but the amount is not equal among species and, even within a certain species, other variables such as type of diet and location contribute to this variation. It is also important to note that each individual fish species has a particular degree of modification of its dietary input, and this change occurs through two pathways: catabolism and conversion, with the inclusion of desaturation and elongation (GULER et al, 2008;INHAMUNS;FRANCO;BATISTA, 2009;TAN et al, 2010;TURCHINI et al, 2007).…”

“…These studies suggest that in flood pulse environments, C. temensis begins to deposit reserves during falling water periods following the end of the rainy season, when prey become concentrated and most readily available. This seasonal variation in both the total body lipid content and the deposition of fat in specific areas in this species Inhamuns et al, 2009) further suggests that reserve deposition may be responsible for observed shape changes and may be related to cyclical color and pattern variation and the reproductive behavior of C. temensis in its natural habitat.

“…Thus, liver and corporal reserves are not utilized in a synchronized manner; rather they are disengaged and complementary. Inhamuns et al (2009) indicated that Cichla sp. contained different ratios of lipid components at different times during the flood pulse and attributed this to differing metabolic and reproductive needs.…”

Previously recognized color and pattern variants of adult Cichla temensis in Amazon flood pulse river environments reflect the cycling of individuals through seasonal sexual maturity and spawning. Individuals also vary in shape from blocky to fusiform. To determine if shape differences are related to patterns of fat reserve deposition and utilization, and to quantify the relationship of shape with color and pattern variation and life history status, specimens in each of four previously defined grades of color and pattern variation were compared using geometric morphometric techniques. Progressive shape changes occurred between grades independent of sex and correlated to gonosomatic index (GSI). Thin plate spline deformation visualizations indicate that the observed shape differences are related to fat deposition patterns. The seasonal timing of shape change and its link to color pattern variation, sexual maturity and local water level conditions suggests a relationship between the physiological and behavioral characteristics of C. temensis and the cyclical flood pulse pattern of its habitat.As variantes de cor e padrão previamente reconhecidos dos adultos de Cichla temensis em ambientes alagáveis amazônicos refletem o ciclo de indivíduos durante o período de maturidade sexual e desova. Indivíduos também variam na forma de oblonga a fusiforme. Para determinar se as diferenças de forma estão relacionadas aos padrões de deposição e utilização das reservas de gordura e quantificar a relação da forma com cor, variação de padrão e status da história de vida, espécimes de cada quatro níveis de cor e variação de padrão previamente definidos foram comparados usando técnicas de morfometria geométrica. Mudanças progressivas ocorreram na forma entre os níveis independentes do sexo e correlacionadas ao índice gonadossomático (IGS). Visualizações de finas deformações na placa da espinha indicam que as diferentes formas observadas estão relacionadas aos padrões de deposição de gordura. O período de mudança de forma e sua ligação com a variação do padrão de cor, maturidade sexual e as condições do nível da água local sugerem uma relação entre as características fisiológicas e comportamentais de Cichla temensis e o padrão de inundação cíclico do seu habitat.
