“…An agreement with the value of weight asymmetry observed in marine fishes (Lychakov et al, 2006) and did not depend on otolith growth rate. Moreover, the absolute value of the otolith non-asymmetry with the fish length and this is a characteristic of the littoral fishes (Lychakov, 2013).…”

“…In the analysis where a large number of specimens is used with clear differences in the fish size, such discrepancies in the otolith weight between the two sides of fish head become minimal (Lychakov et al, 2006).…”

“…Variation in the weight of the fish may be due to the otolith weight differences, which might cause acoustic inadequacies (Lychakov et al, 2006), consequently, the fish cannot avoid the impairment in the function of the sense of hearing.…”

“…Results of several investigators have revealed the function of hearing in the fish will be affected if otolith weight asymmetry becomes lower than the standards stated above for the symmetric fish species (Lychakov et al, 2006). Samarin (1992), Scherer (2001) and Lychakov (2002) have recommended that the mass non-symmetry of otolith might change the quality of reception, which could affect in return the navigation of the fish.…”

Otolith weight difference on both sides of the fish head, x, was estimated. Sagittae otolith mass asymmetry was investigated in the littoral lutjanid species Lutjanus ehrenbergii. The absolute value of |x| in Lutjanus ehrenbergii does correlate with the fish length and otolith development. Such case is similar to that in the symmetrical fish species, the absolute. An increase in the absolute value of otolith asymmetry in relation to the fish size was observed. The range of x magnitude was between -0.2 and +0.2.

“…The inconsistency and incongruity of the otolith from both sides of the head can be due the otolith weight asymmetry that could lead to acoustic imperfections in fishes (Lychakov and Rebane, 2005;Lychakov, 2006). Therefore, the damage in the tasks of the vestibular and auditory sense are unavoidable, but Lychakov et al (2006) suggested that the certain measureable morphological and physiological outcomes of otolith asymmetry are uncertain at this stage.…”

The asymmetry in the mass of the sagitta of the parrotfish species, Chlorurus sordidus and Hipposcarus harid collected from Hurghada, Red Sea coast of Egypt was investigated. In the present study, the weight of the difference between the weight of the sagitta from both the left and right sides was divided by average otolith mass. The results shown that the value of x in the two-species studied does not related to the length of the fish, though the value of otolith weight difference has shown a trend of increase with the fish length. The value of x was calculated to fall between -0.2 and +0.2.

The utricle provides the vestibular reflex pathways with the sensory codes of inertial acceleration of self-motion and head orientation with respect to gravity to control balance and equilibrium. Here we present an anatomical description of this structure in the adult oyster toadfish and establish a morphological basis for interpretation of subsequent functional studies. Light, scanning, and transmission electron microscopy techniques were applied to visualize the sensory epithelium at varying levels of detail, its neural innervation and its synaptic organization. Scanning electron microscopy was used to visualize otolith mass and morphological polarization patterns of hair cells. Afferent nerve fibers were visualized following labeling with biocytin, and light microscope images were used to make three-dimensional (3-D) reconstructions of individual labeled afferents to identify dendritic morphology with respect to epithelial location. Transmission electron micrographs were compiled to create a serial 3-D reconstruction of a labeled afferent over a segment of its dendritic field and to examine the cell-afferent synaptic contacts. Major observations are: a well-defined striola, medial and lateral extra-striolar regions with a zonal organization of hair bundles; prominent lacinia projecting laterally; dependence of hair cell density on macular location; narrow afferent dendritic fields that follow the hair bundle polarization; synaptic specializations issued by afferents are typically directed towards a limited number of 7-13 hair cells, but larger dendritic fields in the medial extra-striola can be associated with > 20 hair cells also; and hair cell synaptic bodies can be confined to only an individual afferent or can synapse upon several afferents.
