The Ageing Unit at the Bedford Institute of Oceanography is responsible for ageing between 5,000-10,000 otoliths annually in support of stock assessments for cod, haddock and silver hake (see Production Ageing).Cod and haddock otoliths are mass-processed: batches of 100 otolith pairs are carefully aligned and embedded in a black polyester resin.

(iii) crystal habit, here defined as any deviation in crystal shape from the predominant orthorhombic aragonite in sagittae and lapilli, or hexagonal vaterite in asterisci; and (iv) overall mineralogy, here defined as relative proportion of orthorhombic aragonite versus hexagonal vaterite visible on an otolith's surface.

The otolith crystals were aragonite according to XRD and Raman analysis. The incremental lines contained C, O, and Ca, with Si as a trace element. In the layer between the incremental lines, Si was not detected. The circadian incremental lines were unclear and irregularly observed in both Lobianchia gemellarii and Diaphus gigas. Their ...

Dec 30, 2019· Otolith structures in the ray Raja clavata and the shark Squalus acanthias may have been known for a long time, but either were mistakenly interpreted as a series of singular crystals [8, 24, 31, 40, 60, 66] or only vaguely described without showing the morphology in detail [32, 67].

Aug 21, 2020· This research examined the impacts of acoustic stress in peled (Coregonus peled Gmelin, 1788), a species commonly cultivated in Russia.This study presents a comparative analysis of the macula sacculi and otoliths, as well as primary hematological and secondary telomere stress responses, in control and sound-exposed peled.

The otolithic membrane is part of the otolith organs in the vestibular system. The otolith organs include the utricle and the saccule.The otolith organs are beds of sensory cells in the inner ear, specifically small patches of hair cells. Overlying the hair cells and their hair bundles is a gelatinous layer and above that layer is the otolithic membrane.

otolith as homogeneous in crystal form, composed almost entirely of monoclinal aragonite crystals (Degens et aI. 1969). The complex crystallinity of the oreo otoliths resembles thatofthe mollusc shell, which, although aragonitic, often has a pattern of complex variation in crystal habit (Carriker et al. 1980).

The stone-like otoliths from the ears of teleost fishes are involved in balance and hearing and consist of calcium carbonate crystallites embedded in a protein framework. We report that a previously unknown gene, starmaker, is required in zebrafish for otolith morphogenesis. Reduction of starmaker activity by injection of modified antisense oligonucleotides causes a change in the crystal ...

Three classes of information are stored in the crystalline structure of the otolith: shape conservation, coexisting crystal morphs, and consecutive changes in crystal morph. Analysis of this crystalline information supports the hypothesis of control of growth of the otolith by proteins from the sensory epithelium or macula.

Aug 01, 2013· The crystal domains observed on the sulcal face of P. mexicana otoliths (Fig. 6a) may correspond to prisms described for other teleost otoliths, in which those prisms build up large parts of the otolith and are arranged radially along the axis of otolith growth (Gauldie, 1993) – similar to the orientation of domains observed here.
