Utilización nutritiva de fuentes de proteína alternativas a la harina de pescado en dietas de engorde para dorada (Sparus aurata)

[ES] Se estudia la utilización nutritiva de niveles crecientes de cuatro fuentes proteicas, harina de soja, de altramuz, harina de gluten de maíz y harina de carne y huesos, alternativas a la harina de pescado en dietas de engorde para dorada, especie que junto con la lubina ha experimentado uno de los mayores índices de crecimiento en el terreno de la acuicultura en los últimos 20 años en Europa

Harina de erizo de mar (Diadema antillarum) com ingrediente alternativo en piensos para bocinegro (Pagrus pagrus): efecto sobre el crecimiento y utilización de la dieta

[EN]The effect of dietary inclusion of sea urchin meal (Diadema antillarum) on growth and feed utilization was investigated in a growth trial with red porgy (Pagus pagrus) of 208g initial body weight, during 6 month feeding period. High quality fish meal and fish oil diet was used as a control (Diet C); urchin meal was included at 8% and 16% dietary levels (EM8 and EM16). Compared to the control diet higher values for absolute and relative final weight and SGR were obtained either for fish fed EM8 and EM16 diets; for the latter diets values for FCR and final HSI were significantly smaller respect to those for the control diets. No differences were found among diets for the total feed intake, VSI and K factor. Obtained results indicate the suitability of the sea urchin meal as alternative ingredient in diets for the red porgy, improving fish growth and feed utilization. More studies are being done at the moment in red porgy and other fish species in order to better determine the optimum dietary levels taking into account other important culture and quality parameters.

Utilización de cangrejo y harinas en un pienso para pulpo común Octopus vulgaris

The present work evaluates whether the addition of 2 species of crab (Portunus pelagicus and Grapsus grapsus) as attractants (10%) in experimental moist diet based in discarded bogue (Boops boops) may increase ingestion and growth in O. vulgaris. Besides, another diet based on flour, made from discarded bogue and G. grapsus, was tested. Finally, a 40-60% discarded bogue-crab P. pelagicus was provided as a control diet. Four male octopuses, kept The present work evaluates whether the addition of 2 species of crab (Portunus pelagicus and Grapsus grapsus) as attractants (10%) in experimental moist diet based in discarded bogue (Boops boops) may increase ingestion and growth in O. vulgaris. Besides, another diet based on flour, made from discarded bogue and G. grapsus, was tested. Finally, a 40-60% discarded bogue-crab P. pelagicus was provided as a control diet. Four male octopuses, kept in PVC net cages in the same tank, were fed each diet for 8 weeks and several parameters were calculated: absolute growth rate (AGR, g./day), standard feeding rate (SFR, %/day) and feed efficiency (FE). The addition of crab to the diet under the conditions described did not improve ingestion, growth or feed efficiency in this species, while the flour based diet generated negative growth.

Efecto de la inclusión de harinas de cangrejo de diferente origen en piensos para bocinegro (Pagrus pagrus) sobre el crecimiento, utilización de la dieta y coloración de la piel

[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.

Propagación in vitro de Cymodocea nodosa para su utilización en la restauración de sebadales

[ES] Las técnicas de propagación in vitro son consideradas como una de las soluciones más plausibles al declive de las comunidades de fanerógamas que actualmente se registra en todo el mundo. En este trabajo, se establecieron cultivos de Cymodocea nodosa, a partir de explantos, que mediante multiplicación vegetativa o formación de callo previo emitieron hojas nuevas en medios que contenían la citoquinina TDZ. Otros reguladores afectaron a la extensión y la regeneración de la hoja. Los fragmentos, constituidos por hoja, rizoma y raíz, se comportaban como una unidad fisiológica, donde el carbono fijado por la hoja era rápidamente traslocado al resto del tejido. Estos explantos asimilaron preferentemente el amonio y el fosfato inorgánico, siendo indispensable la presencia de tejido sumergido para mantener los niveles de fósforo.
