description |
In this work, we compared the proportion of proteins, lipids, carbohydrates and fatty acids in populations of Artemia sp. from the Araya saltworks in northeastern Venezuela, during two stages (nauplii and metanauplii) of their development. The population of Artemia franciscana from San Francisco Bay (USA) was used as reference because of its wide use in aquaculture. The organisms of both populations showed significant differences in protein, lipid, carbohydrate and phospholipid contents between both stages; however, no significant differences were established between both populations. The highest protein concentrations were found in metanauplii: 67% for Araya and 56% for San Francisco. The highest concentrations of lipids (22% and 24%), carbohydrates (17% and 11%) and phospholipids (26% and 35%) were found in nauplii for both populations. Cholesterol esters, cholesterol, triglycerids, and n-3 and n-6 fatty acids were significantly different between stages and between populations. Cholesterol esters, and n-3 and n-6 fatty acids were higher in San Francisco metanauplii, with values of 37%, 11% and 7%, respectively. The highest triglycerid concentration (39%) was found in San Francisco nauplii and the highest cholesterol concentration in Araya metanauplii (50%). The results suggest that the Artemia population from the Araya saltworks contains the necessary elements to cover the nutritional requirements of fish larvae and marine crustaceans under culture. |

En el presente trabajo se establecieron comparaciones entre la proporción de proteínas, lípidos, carbohidratos y ácidos grasos en dos estadios (nauplios y metanauplios) de Artemia sp. proveniente de la salina de Araya, nororiente de Venezuela. La población de Artemia franciscana de San Francisco (EUA) se empleó con fines de referencia, debido a su uso en actividades de acuicultura. Los organismos analizados de ambas poblaciones presentaron diferencias significativas en el contenido de proteínas, lípidos, carbohidratos y fosfolípidos entre los diferentes estadios; no obstante, entre poblaciones no se establecieron diferencias significativas. Las mayores concentraciones de proteínas se registraron en los metanauplios, con 67% para los organismos de Araya y 56% para los de San Francisco. Las mayores concentraciones de lípidos (22% y 24%), carbohidratos (17% y 11%) y fosfolípidos (26% y 35%, respectivamente) se encontraron en los nauplios tanto de Araya como los de San Francisco. Los ésteres de colesterol, el colesterol, los triglicéridos y los ácidos grasos n-3 y n-6 fueron significativamente diferentes entre los estadios y las poblaciones analizadas. Los ésteres de colesterol y los ácidos grasos n-3 y n-6 fueron mayores en los metanauplios de la población de San Francisco, con valores de 37%, 11% y 7%, respectivamente. La mayor concentración de triglicéridos se encontró en los nauplios de San Francisco (39%), mientras que la mayor concentración de colesterol estuvo en los metanauplios de Araya (50%). Los resultados sugieren que la población de Artemia sp. de Araya reúne componentes nutricionales para cubrir las necesidades alimenticias, particularmente de larvas de peces y crustáceos marinos bajo condiciones de cultivo. 2003-03-06 2021-06-03T03:55:03Z 2021-06-03T03:55:03Z info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Peer-reviewed Article Artículo Arbitrado https://www.cienciasmarinas.com.mx/index.php/cmarinas/article/view/186 10.7773/cm.v29i42.186 https://hdl.handle.net/20.500.12930/7363 eng https://www.cienciasmarinas.com.mx/index.php/cmarinas/article/view/186/161 application/pdf Iniversidad Autónoma de Baja California Ciencias Marinas; Vol. 29 No. 4B (2003); 655-663 Ciencias Marinas; Vol. 29 Núm. 4B (2003); 655-663 2395-9053 0185-3880 |
