“…Sagitta growth is however favoured along the antero-posterior axis, on their distal and ventral sides, although the a priori available growing surfaces appear to be the proximal and dorsal faces. This type of developmental process notably departs from the model proposed by Gauldie and Nelson (1990), in which physical contact of the otolith against the ventral portion of the cranium restricted otolith growth on the ventral edge. From the tenuis larva (Fig.…”

“…For a relevant interpretation of otolith-stored information, the main difficulty is to discriminate between the roles played by each of these determinants. Among the intrinsic factors, Gauldie and Nelson (1990) suggested that the sagitta position in the otic capsule could act upon its growth. To our knowledge, previous studies have not dealt with relationships between the sagitta and otic cavity, or reported on eventual constraints imposed by the bony structures during otolith formation.…”

“…9C), or, more often, one positioned closer to the antisulcal side (Dunkelberger et al 1980;Gauldie and Nelson 1990). Both this shape and nucleus location resulted from the release of soluble Ca 2+ on the proximal side, which was in turn precipitated as CaCO 3 crystals due to an increasing alkaline gradient, from the sulcal area towards the otolith edge (Mugiya 1974;Gauldie and Nelson 1990).…”

“…Otolith growth depends on endogeneous rhythms that control the deposition of matrix-dominant (D-unit) and mineraldominant (L-unit) layers. This process varies under pressure of ontogenical and environmental events, via fish physiology and metabolism (Campana and Neilson 1985;Gauldie and Nelson 1990;Gauldie et al 1991;Morales-Nin 2000). Otoliths record significant ontogenetic and ecological events as major discontinuities (''landmarks'', Campana and Jones 1992).…”

Relationships between inner ear and sagitta growth during ontogenesis of three Carapini species, and consequences of life-history events on the otolith microstructure

2002

Three species of Carapidae have in common a tenuis larval stage, during which they settle in the lagoon and take refuge in the same species of holothuroid. From the juvenile stage, Carapus homei and C. boraborensis are commensal, whereas Encheliophis gracilis is parasitic. The aims of this study were to analyse to what extent the ontogenetic changes of the otic capsule affected the shape of the inner ear and how environmental cues, due to the above-mentioned life history and the style, could influence the structure of the sagitta. Sagittal sections revealed a three-dimensional asymmetry with a nucleus close to the proximal surface. Observations of the growth axis of the sagitta suggest it has a morphogenetic impact on the otic cavity. Each sagitta contains three main zones related to the life stages of the fish. Bands and checks were observed in the third zone in C. homei and C. boraborensis, but this pattern was less discernible in E. gracilis. These structural differences in zone 3 could be related to the commensal and parasitic life styles of these fishes. Further studies dealing with otosac features and otolith functions are suggested.

“…The relationship between fish size and otolith shape reflects the combined effects of ontogeny and the environment on otolith shape (Vignon 2012). The overall species-specific shape of the otolith and the nature of its development during ontogeny from the circular larval otolith to the more complex morphology of the adult otolith is genetically determined (Hüssy 2008;Reichenbacher et al 2009;Vignon and Morat 2010), with exogenous factors having a modulating effect through, for example, the effects of feeding and growth on the nature of crystal formation (Gauldie and Nelson 1990) and the rate of protein accretion in the otolith (Hüssy 2008). The shape of the otolith may also reflect its physiological function in hearing and balance, and such variation can have an adaptive significance.…”

Abstract. Two stocks of bluefin tuna (Thunnus thynnus) inhabit the north Atlantic; the western and eastern stocks spawn in the Gulf of Mexico and the Mediterranean Sea respectively. Trans-Atlantic movements occur outside spawning time whereas natal homing maintains stock structure. Commercial fisheries may exploit a mixed assemblage of both stocks. The incorporation of mixing rates into stock assessment is precluded by uncertainties surrounding stock discrimination. Otolith shape descriptors were used to characterise western and eastern stocks of Atlantic bluefin tuna in the present study and to estimate stock composition in catches of unknown origin. Otolith shape varied with length and between locations and years. Within a restricted size range (200-297-cm fork length (FL)) the two stocks were distinguished with an accuracy of 83%. Bayesian stock mixture analysis indicated that samples from the east Atlantic and Mediterranean were predominantly of eastern origin. The proportion assigned to the eastern stock showed slight spatial variation; however, overlapping 95% credible intervals indicated no significant difference (200-297 cm FL: central Atlantic, 73-100%; Straits of Gibraltar, 73-100%; Morocco, 50-99%; Portugal 64-100%). Otolith shape could be used in combination with other population markers to improve the accuracy of mixing rate estimates for Atlantic bluefin tuna.

Trace elements and stable isotope ratios in otoliths have been used as proxies for the migration history of teleosts; however, their application in oceanic fishes remains limited. This study reports the first use of radiocarbons in otoliths to evaluate the horizontal migration histories of an oceanic fish species, the walleye pollock Gadus chalcogrammus. We conducted radiocarbon analyses of three stocks sourced from Hokkaido, Japan. The radiocarbon concentrations from the outermost portion of the otoliths from the Japanese Pacific, Northern Japan Sea (JS), and Southern Okhotsk Sea (OS) stocks were in general agreement with the seawater radiocarbon concentration of the sampling region, suggesting that pollock of all three stocks generally inhabited the within the sea region where each pollocks were sampled throughout their life cycle. However, the radiocarbon signals also provided some indications that some JS and OS stocks may be migrating between different sea regions. The proposed novel approach of reconstructing the individual migration history of marine fish using radiocarbon in otoliths may help examine fish migration with a higher temporal and spatial resolution that could not be achieved by trace elements and stable isotope ratios.
