Clearance rate of the mussel Mytilus galloprovincialis. I. Response to extreme chlorophyll ranges

Clearance rate (CR) measurements in Mytilus galloprovincialis were determined over 16 experiments in which the mussels were exposed to diets characterized by variable chlorophyll content (0.28–104.88 µg Chla L–1) in order to: (1) establish the lower trigger level and the saturation reduction, (2) el...

The results demonstrated that time exerted a significant effect on CR, which varied throughout the experiment in different diets. The CR response differed fundamentally in the significant reduction of CR after prolonged exposure to low and high chlorophyll-content diets compared with the medium ones. Taking into account the data from the sixth hour onwards, a sharp lower trigger level threshold was established at 2.08 µg Chla L–1, showing an on/off CR response. The threshold for saturation reduction was about 26.91 µg Chla L–1 and showed a progressive response to chlorophyll concentration. Se realizaron 16 experimentos en los que se determinó la tasa de aclaramiento (TA) en Mytilus galloprovincialis sometido a dietas con distinto contenido de clorofila (0.28–104.88 µg Chla L–1) con objeto de: (1) establecer su umbral de activación y de saturación, (2) dilucidar si estos umbrales están regidos por una respuesta de tipo encendido/apagado o bien por una respuesta progresiva, y (3) determinar el efecto del tiempo de experimentación en la medida de la TA en condiciones extremas, cuantificadas en términos de contenido en clorofila. Los resultados del presente trabajo pusieron de manifiesto que el tiempo de experimentación ejerce un efecto significativo sobre el comportamiento de la TA, la cual varió a lo largo del experimento con diferentes dietas. La respuesta de la TA difirió fundamentalmente en su reducción significativa tras de una exposición prolongada a dietas con alto o bajo contenido de clorofila en comparación con dietas con contenido medio. Teniendo en cuenta los datos a partir de la sexta hora de experimentación, se observó un abrupto umbral de activación a una concentración de clorofila de 2.08 µg L–1, mostrando una respuesta de tipo encendido/apagado. En el caso del umbral de saturación, la concentración de clorofila a partir de la cual se apreció una reducción de la TA se situó en torno a 26.91 µg Chla L–1, mostrando una reducción progresiva con la concentración de clorofila de la dieta.Iniversidad Autónoma de Baja California2009-12-08info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionPeer-reviewed Article Artículo Arbitradoapplication/pdfhttps://www.cienciasmarinas.com.mx/index.php/cmarinas/article/view/164510.7773/cm.v35i4.1645Ciencias Marinas; Vol. 35 No. 4 (2009); 405-417Ciencias Marinas; Vol. 35 Núm. 4 (2009); 405-4172395-90530185-3880reponame:Ciencias Marinasinstname:UNIVERSIDAD AUTÓNOMA DE BAJA CALIFORNIAinstacron:UABCenghttps://www.cienciasmarinas.com.mx/index.php/cmarinas/article/view/1645/1786info:eu-repo/semantics/openAccessoai:cienciasmarinas.com.mx:article/16452024-08-22T17:01:39Z
