[EN]The inclusion of two different crab meals in diets on fillet quality parameters was investigated in a six month growth trial with red porgy (Pagus pagrus). A high quality fish meal and fish oil diet was used as a control (Diet C). Fish meal protein in the control diet was replaced by increasing levels of protein from a river crab meal (Procamburus clarkii) (CR) and a marine crab meal (Chaceon affinis) (CM) at 10% and 20% each of them. The inclusion of both crab meals in diets, either at 10% and 20% substitution levels, did not affect the texture quality parameters of flesh except for the adhesiveness, where animal fed on CR20 showed the smallest value respect to those fed the Diet C. Compared to the control fish, a reduction of the fillet lipid oxidation indicated by the Tbars index was observed for fish fed both crab meal based diets, at the higher inclusion level (20%). Increasing dietary levels of the marine crab meal showed an increment of the monoenoicos, n-9 and oleic fatty acid content in the fillets. Results indicate that both crab meals used in present study are suitable as alternative ingredients for red porgy diets in terms of fish flesh quality.

[EN] The effect of dietary inclusion of two type of crab meal on growth, feed utilization and skin coloration performance was investigated in a growth trial with red porgy (Pagrus pagrus) of 233g initial body weight, during 6 month feeding period. High quality fish meal and fish oil diet was used as a control (Diet C). Protein of fish meal in the control was replaced by increasing dietary levels of protein derived from a river crab meal (Procamburus clarkii) (CR) and a marine crab meal (Chaceon affinis) (CM) at 10% and 20% each of them. Regarding growth results, fish fed the CM20 diet showed the highest values in absolute final weight and percent of the initial weight. For animals fed the crab meal based diets, the colour result was better than that of fish fed the control one, showing skin redness similar to that of the wild specimens. For both ingredients, increasing dietary inclusions were accompanied for an increment of the colour saturation, being in this case the obtained value for the CR meal higher than those for the CM meal. Present results indicate that crab meals used in this study are suitable as partial replacers for fish meal in diets for the red porgy.

[ES] La escasa disponibilidad y el alto coste del aceite de pescado han impulsado a los científicos a buscar fuentes alternativas a este recurso, como por ejemplo los aceites vegetales. En este estudio hemos evaluado el efecto de dos diferentes fuentes lipídicas vegetales (lino y soja) sobre el estado de salud de la dorada. Los resultados indicaron que tanto una elevada (70%) como la total (100%) sustitución de aceite de pescado por aceites vegetales en la dieta de juveniles de dorada influyen negativamente en el crecimiento y conversión del alimento. Todas las dietas, con excepción de la del 70% de sustitución, presentaron un menor crecimiento y un peso final significativamente menor (p< 0,05) que el control. La composición lipídica dietética se reflejó en los ácidos grasos de los macrófagos del riñón anterior, aunque se observó una incorporación selectiva de ARA y EPA. La expresión de Mx en respuesta a ambos estímulos (bacteria y Poli I: C) fue homogénea en todos los grupos, pero los niveles basales fueron más altos en los peces alimentados con dieta vegetal. Este resultado podría indicar un posible efecto beneficioso de los lípidos vegetales sobre el sistema inmune de los peces.

"[ES] En España las posibilidades de empleo de las personas en riesgo de exclusión social no son satisfactorias. Se trata de un problema que centramos en las concepciones educativas de la enseñanza-aprendizaje inicial, que orientan minoritariamente a la formación para el empleo como a la oferta y demanda de trabajo de esos colectivos. En nuestro sistema educativo de la desatención y marginación del alumnado en riesgo de exclusión social se pasó a la educación especial; luego, a la normalización e integración, lo que condujo a la inclusión educativa. En ese momento final que nos encontramos aparecen visiones innovadoras como la escuela para todos, empleo con apoyo, y vida con apoyo que desarrollan el paradigma de la autonomía y vida independiente. [EN] Employment chances for people in risk of social exclusion are not satisfactory in Spain. This has been a problem at the core of educational conceptions concerning primary education, scarcely orientated towards the employment of such groups. In our system, from margination and neglect of our pupils in risk of social exclusion, we sent them to special education first, then to normalization and integration and finally to inclusive education. Nowadays, innovative visions such as school for all, employment and life with support are developing the model of autonomy and independent life. "
