Milne-Edwards, 1882 and the Pacific Hydrothermal Vent Crab, Bythograea Thermydron Williams, 1980 (Decapoda, Brachyura) Company, Joan B. Thuesen, Erik V. Childress, James J. Rotllant, Guiomar Zal, Franck 19 pages, 3 figures, 3 tables [EN] Changes in enzymatic activities and protein content of leg muscle and hepatopancreas tissue of two deep-sea crabs were studied after 34 days of food deprivation. Geryon longipes and Bythograea thermydron are the most abundant deep-sea crab species in their respective environment. Geryon longipes dwells on the middle and lower slope of the northwestern Mediterranean Sea and has a bathymetric range between 450 and 1950 m depth. Bythograea thermydron dwells in Pacific hydrothermal vent sites and has a bathymetric range between 2000 and 3000 m depth. After 34 days under laboratory conditions, citrate synthase activities in the hepatopancreas of G. longipes and B. thermydron were found to be much lower in food-deprived crabs compared to fed crabs. In both species, no lactate dehydrogenase activity was detected in hepatopancreas tissue, and no food deprivation effects were observed for either lactate dehydrogenase or citrate synthase activities in leg muscle tissue. No changes in protein were found after 34 days of food deprivation, either. Enzyme activities of fed and food-deprived specimens maintained in the laboratory encompassed the natural range of variation measured in freshly caught crabs of both species. Lactate dehydrogenase, citrate synthase, and protein content of freshly caught specimens of G. longipes were significantly lower than in freshly caught specimens of B. thermydron. The results are discussed taking into account the surrounding environmental features both species encounter and from the point of view of the potential use of citrate synthase activity as an indicator of nutritional condition in deep-sea crustaceans. © 2008 Brill Academic Publishers [ES] Los cambios en las actividades enzimáticas y en el contenido de proteínas en los tejidos de músculo y de hepatopáncreas de dos cangrejos de gran profundidad fueron estudiados después de 34 días de ayuno. Geryon longipes y Bythograea thermydron son las dos especies de cangrejo de gran profundidad más abundantes en sus respectivos hábitats. Geryon longipes se distribuye en el talud medio e inferior del Mediterráneo noroeste y presenta un rango batimétrico entre los 450 y 1950 m de profundidad. Bythograea thermydron se distribuye en las fumarolas hidrotermales del Pacífico y presenta un rango batimétrico entre los 2000 y 3000 m de profundidad. Después de estar 34 días en condiciones de laboratorio, las actividades de la citrato sintetasa en el hepatopáncreas de G. longipes y B. thermydron fueron inferiores en los cangrejos mantenidos en ayunas comparadas con las actividades de los cangrejos alimentados. En ninguna de las dos especies se detecto actividad de la enzima lactato deshidrogenasa del hepatopáncreas, y no se observaron efectos del ayuno en la actividad de la lactato deshidrogenasa ni de la citrato sintetasa del tejido muscular. Tampoco se encontraron cambios en el contenido de proteínas después de 34 días de ayuno en ninguna de las dos especies estudiadas. Las actividades enzimáticas de los individuos alimentados y la de los no alimentados, ambos mantenidos en laboratorio, abarcaron el rango de variación natural encontrado en los cangrejos de ambas especies analizados inmediatamente después de ser capturados. La actividad de la lactato deshidrogenasa, de la cintrato sintetasa, y el contenido en proteínas de los individuos recién capturados de G. longipes fueron significativamente inferiores con respecto a los individuos recién capturados de B. thermydron. Los resultados se discuten en base a las condiciones ambientales de cada uno de los hábitats donde las especies se distribuyen y en base al potencial uso de la actividad de la citrato sintetasa como indicador de la condición nutricional de los crustáceos de gran profundidad The work reported in this study was supported by grant GRQ 95/8.039 (“Generalitat de Catalunya”) to F.
