Otolith atlas of fish of the Sinos River.
Otoliths are calcium carbonate structures located in the inner ear of fish; they are responsible for hearing and balance. The inner ear has three pairs of otoliths: the lapilli, the sagittae and the asterisci. The sagittae otoliths are the largest and their format is species-specific. Because of their composition, otoliths can resist to the digestive tract of ichthyophagous species, and they ca...
متن کاملRelationship between fish length, otolith length and weigth of Sind sardine Sardinella sindensis, (Day, 1878) from coastal waters of Jask (Oman Sea)
Correlation between fish length, length and weight of otolith of sardine in the Southern waters of Iran still unknown. Therefore, because of commercial and ecological importance of Sardinella sindensis, relationships between fish length (total length), length and weight otolith was studied.

متن کاملAge determination and morphological study using otoliths in Cyprinus carpio Linnaeus, 1758 in the Southern Caspian Sea
The relationships between sagitta otolith morphology and fish size were examined for common carp in the Southern Caspian Sea and also the aging of different length groups were determined. Statistical tests to examine correlation between left and right otoliths dimensions were carried out and no statistically significant difference between them was found. The biggest otolith had 0.032g weight be...
