“…Moreover, the incorporation of the calcium at the level of the edges involves a decrease in the Ca 2+ concentration and a weaker development of the distal side. This process has been corroborated by recent studies dealing with the various , 1997;Takagi, 1997Takagi, , 2000aPisam et al, 1998), which were shown to be responsible for the establishment of a proximo-distal gradient favoring the CaCO 3 deposit on the sulcal side (Payan et al, 1999(Payan et al, , 2004. In Carapidae, the saccular epithelium presents the typical zones found in different teleosts (Pisam et al, 1998;Takagi, 1997Takagi, , 2000aTakagi, , 2002, indicating that the different zones should have the same properties.…”

The biomineralization of otoliths results mainly from the release of soluble Ca 2+, which is in turn precipitated as CaCO 3 crystals. In some Carapidae, sagittae sections have been shown to reveal a three-dimensional asymmetry with a nucleus close to the sulcal side, an unusual position. This study seeks to understand otolith formation in Carapus boraborensis. The unusual shape of the otolith is partly explained by the distribution of the epithelium cells, and particularly the sensory epithelium. Experimental evidence shows for the first time that aragonite growth takes place along the c-axis. These aragonite needles present two different habits. On the sulcal side is found the acicular form resulting from rapid growth during a short period of time. On the anti-sulcal side, the prismatic form seen there is due to a slower growth speed over longer periods. The otolith surface was observed each hour during a period of 24 h in fishes reared in similar conditions. This allowed for the first time the direct observation on the otolith surface of the deposition of the two layers (L-zone and D-zone). In C. boraborensis, the organic-rich layer (D-zone) develops during the day, whereas the CaCO 3 layer (L-zone) seems to be deposited during the night.

“…These patterns may have arisen simply due to differences in precipitation rates and therefore incorporation dynamics of elemental impurities (Strasser et al 2008, Walther et al 2010). In addition, other studies have quantified the elemental composition of the endolymph fluid from which the otolith is mineralized and found heterogeneity between dissolved elements and proteins in the proximal and distal regions of the endolymph (Payan et al 1999(Payan et al , 2004b. The endolymph fluid in trout was found to contain 20% higher Na + concentration on the proximal side, which is the same side on which the sulcus is formed (Payan et al 1999).…”

“…The uptake of elements into otoliths strictly depends on the element composition of the endolymph, an acellular medium, which is secreted by the inner ear epithelium (Payan et al 2004). Active element and ion discrimination at several barriers along the way from the environment to the endolymph causes a decoupling of otolith increment from ambient conditions or food composition (Payan et al 2004;Campana 1999). Food-carried elements are selected at intestine/blood, blood/inner ear epithelium as well as inner ear epithelium/endolymph barriers (Payan et al 2004).…”

Dietary effects on multi-element composition of European eel (Anguilla anguilla) otoliths

Otolith microchemistry is widely used as a tool to track individual migration pathways of diadromous Wsh under the assumption that the elemental composition of Wsh otoliths is directly inXuenced by the physicochemical properties of the surrounding water. Nevertheless, several endogenous factors are reported to aVect element incorporation into Wsh otoliths and might lead to misinterpretations of migration studies. This study experimentally examined the inXuence of eight diVerent diets on the microchemical composition of European eel (Anguilla anguilla) otoliths using laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS). Seven natural prey types and one artiWcial diet were fed during 8 weeks in freshwater circuits. Results show for the Wrst time that food has no signiWcant inXuence on the incorporation of Na, Sr, Ba, Mg, Mn, Cu and Y into European eel otoliths. This indicates that the incorporation of elements usually chosen for migration studies is not aVected by diet and that individual feeding behaviour of A. anguilla will not lead to any misinterpretation of migration pathways.
