Determining Age and Morphology of Aspius Aspius Taeniatus (Mung Fish) Using Otolith in the South Basin of Caspian Sea

After weighing otolith separated from Aspius aspius taeniatus fish in south basin of Caspian Sea, morphological studies were done such as determining length, width, area, and perimeter. The age of otolith was determined after cutting. Analysis of relationship between otolith parameters and fish age show weight and length of otolith are correlated with the age. The best indicators in determining age of Aspius aspius taeniatus are otolith weight (R=0.96), and length (R=0.82). Relationship between morphological parameters of otolith and size of Aspius aspius taeniatus fish (length and weight) indicate length, weight, perimeter and area of otolith are good indicators in determining length and weight of fish body. Exponential relationship between length and weight of the fish body was measured by correlation higher than R=0.96.
