Se estudió el reemplazo total de aceite de hígado de bacalao por aceites vegetales en las dietas de juveniles de lenguado de California (Paralichthys californicus). Se formularon cinco dietas con aceites de oliva, maíz, linaza y dos combinaciones de linaza y maíz, y se compararon con una dieta testigo que contenía aceite de hígado de bacalao. Después de 12 semanas de experimentación se observó un crecimiento mayor en los ejemplares alimentados con la dieta testigo; sin embargo, no hubo diferencias significativas en crecimiento y supervivencia entre las dietas experimentales. Los ácidos grasos provenientes de los aceites de linaza, maíz y oliva fueron los más acumulados en los tejidos, incrementando en proporción al total de ácidos grasos. Una reducción de 20:5n-3 y 20:4n-6 en presencia de altos niveles dietéticos de 18:3n-3 y 18:2n-6 sugiere que, como en la mayoría de los peces, la síntesis de 18:3n-3 a 20:5n-3 y de 18:2n-6 a 20:4n-6 es muy baja o inexistente. Aun cuando el contenido de 22:6n-3 en el músculo de los ejemplares alimentados con la dieta testigo fue aproximadamente de 2.0 a 2.5 veces más alto que en el de los ejemplares alimentados con las dietas experimentales, no se observaron diferencias significativas. Un decremento proporcional de 20:5n-3 en comparación con todos los ácidos grasos y la ausencia de un incremento en el tejido sugiere que este ácido graso se utilizó en la síntesis de 22:6n-3. Las reducciones significativas en el nivel de 20:5n-3 indican que si se hubiera realizado el experimento durante un periodo de tiempo más largo, se hubiera llegado a un nivel en donde se registrarían efectos adversos en el crecimiento. Es necesario realizar más estudios, especialmente sobre los cambios proporcionales y cuantitativos de 20:5n-3 y 22:6n-3 en la composición del tejido muscular. |
