The Age Determination of Black Pomfret (Parastromateus niger), based on Otolith Cross Sections in Iranian Coast of Oman Sea

Reza Yadollahvand and Behzad Rahnama

This study was conducted to determine the age of Black Pomfret (Parastromateus niger), based on otolith cross sections. The age of Black Pomfret was determined in the Oman Sea (Sistan and Baluchistan province), examining 94 specimens, in September 2012. From 94 otolith, 36 was sectioned and determined by age. The oldest specimen belonged to the female, with the total length of 56 cm, 6 years old and also the youngest specimen belonged to the female, with the total length of 21 cm, was estimated in 1 year. The smallest and largest specimens were 21 and 56 cm and 190 and 2161 g, respectively. The relationship between otolith size and the size and age of the fish showed that the otolith size has a strong and direct correlation with the age, total length and weight of the fish.
