Characterization and variations of organic parameters in teleost fish endolymph during day-night cycle, starvation and stress conditions

Author(s) : Guibbolini M , Borelli G , Mayer Gostan N , Priouzeau F , De Pontual Helene , Allemand D , Payan P
Description : The aim of the present work was to examine the modifications of the organic composition of fish endolymph under environmental conditions (day-night cycle, starvation and Cl-2-Stress) known to modify otolith growth. Endolymph electrophoretic patterns were compared. An antibody raised against the trou...

Daily variations of endolymph composition: relationship with the otolith calcification process in trout

Author(s) : Borelli G , Guibbohni M , Mayer Gostan N , Priouzeau France , De Pontual Helene , Allemand D , Puverel S , Tambutte E , Payan P
Description : Ionic and organic parameters of the otolith calcification process in the trout Oncorhynchus mykiss were analysed in plasma and endolymph over the day:night cycle. Plasma pH remained constant and total CO2 concentration was significantly lower (by 21%) during the day than at night. Calcifying paramet...

Reconstructing individual food and growth histories from biogenic carbonates

Author(s) : Pecquerie, Laure , Fablet, Ronan , De Pontual, Helene , Bonhommeau, Sylvain , Alunno-bruscia, Marianne , Petitgas, Pierre
Description : Environmental conditions experienced by aquatic organisms are archived in biogenic carbonates such as fish otoliths, bivalve shells and coral skeletons. These calcified structures present an accretionary growth and variations in optical properties - color or opacity - that are used to reconstruct ti...
