Stock assessment and population dynamics of Acipenser persicus in the southern Caspian Sea (Iranian Waters)
In order to the Persian sturgeon stocks in the Southern part of Caspian Sea (Iranian side), the present study was carried out by measuring different population parameters (length, age, weight), and changes of catch effect and CPUE. Although, the amount of sturgeon stocks have considerably been decreased during previous years, but according to the collected data, the stock and amount of catch of A. persicus was increased. During last decade, the catch per unit effort fluctuated from 2.249 to 2.971 kg. Also, mean length, weight and age of this species were declined and the age-structure showed significant changes. In total, the results showed that the young population of Persian sturgeon is increasing and catch data of this species showed an increase, too.
