| Current study analyzes the chemical composition of lipids in fish commonly found in the dams of the state of Ceará, Brazil, namely Pterygoplichthys pardalis (bodó), Hoplias malabaricus (traira), Cichla ocellaris (tucunaré), Prochilodus brevis (curimatã) and Oreochomis niloticus (tilapia). The animals were collected during the summer and Folch extraction procedure was used for the extraction of lipids, whilst Iupac methodology (International Union of Pure and Applied Chemistry [Iupac], 1987) was used to methylate the fatty acids. Methyl esters were analyzed by GC/MS and the different components in fish oil were identified. Palmitic acid, C16:0 (35.71-45.02%), was the saturated fatty acid with the highest percentage, while oleic acid, C18:1Δ9 (10.62-25.29%)... |

| O objetivo do trabalho foi avaliar o crescimento, a composição e o perfil lipídico corporal de jundiás criados em diferentes densidades de estocagem (DE: 4,2; 6,4; 8,6 e 10,8kg m-3) em sistema com recirculação de água. Durante 120 dias, 420 peixes (peso inicial=182,95±2,96g) foram alimentados uma vez ao dia, até a saciedade aparente, com dieta peletizada formulada. Observou-se que, quanto maior a DE utilizada, menor é o peso individual dos peixes, entretanto a biomassa por tanque aumentou (P<0,05). Melhor conversão alimentar (1,69) e maior quantidade de gordura intraperitoneal (3,92) foram observadas nos peixes submetidos à densidade 4,2kg m-3. A proteína corporal foi afetada pelas DEs. Ocorreu diminuição dos ácidos graxos saturados e aumento dos... |

| ABSTRACT: The objective of this paper was to estimate the genetic divergence among 49 soybean ( Glycine max L. Merrill .) genotypes to assist grain quality-focused breeding programs in the choice of progenitors. The genetic divergence was estimated using the Mahalanobis generalized distance from the percentages of protein, oil, and fatty acids oleic, linoleic and linolenic after cultivation of genotypes in different environments. Genotypes were grouped by agglomerative methods and the two and three-dimensional projections of the distance matrix were obtained. The average protein and oil contents in the four environments ranged from 34.25 to 45.18% and from 16.48 to 23.01%, respectively. The average contents of the fatty acids oleic, linoleic and linolenic... |
