Using high performance liquid chromatography, X-ray diffraction and Fourier transformation infrared spectra, the authors characterized the sorted proteins from different otoliths. It is found that the three types of proteins in lapillus and asteriscus have different characteristics, and such differences may be responsible for different kinds of crystalline state in calcium carbonate.

Otoliths remained steadily growing during metamorphoses, the number of otolith DGIs deposited after TC marks as consistant with the rearing days(p＜0.01) which validate the daily periodicity of the otolith increment deposition of Pacific tarpon leptocephali during metamorphoses. As for otolith microchemistry, Sr/Ca ratios in otolith of the fish decreased in accompany with metamorphosis, while Na/Ca ratios in otolith changed oppositely as Sr/Ca ratio.

The head is slowly turned 90° toward the side where nystagmus is induced less intensely. Then the head is rotated 180° rapidly toward the opposite side. This article reports three cases of the ageotropic form of HC-BPPV that were cured by rapid head rotation. The three cases demonstrated that rapid head rotation was an effective maneuver to treat cupulolithiasis on the utricle side. It is recommended that rapid head rotation can be used for therapeutic diagnosis: If nystagmus subsides immediately after this maneuver, the diagnosis is cupulolithias is on utricle side. If nystagmus changes into the geotropic form, the diagnosis is cupulolithiasis on canal side or canalolithiasis in the anterior arm of horizontal semicircular canal. A repositioning maneuver for geotropic form can then be applied to treat these patients.

Several basic tenrts of otolith research have been questioned recently with regard to eel metamorphosis.specifically,some researchers have suggested that otolith increment formation is not daily,and otolith material may be resorped during metamorphosis.we conducted a rearing experiment to test the hypothesis that increment formation is daily and that the otolith continues to grow during eel metamorphosis.we marked the otolith of wild-caught leptocephali and reared these fish through metamorphosis.metamorphosis was characterized by a decreasing standard length,pre-anal length,and body depth accompanied by an increase in pigmentation and a change in behavior.

Otolith is calcareous concretions in fish inner earsIts composition and structure are very stableIts accretional growth follows a circadian rhythm that is physiologically controlled and influenced by environmental conditionsOtolith acts as biological archives providing the basis for the reconstruction of individual life traits and environmental parametersThe paper focuses on fish otolith trace elements and their isotopes, general testing methods and the prospect and problems of its application in environmental detection in recent 20 years, hoping that it could provide researchers with some thoughts and could expand its potential application in environmental science.
