Abstract :
Mullet transferred to the Caspian Sea in 1930 from the Black Sea. This is possible over 80 years of adapting to the conditions of the Caspian Sea, to change some of morphology features. This study aimed to compare the above characteristics with their fellow Black Sea and changes in the new environment has been adaptation. The study designed with objective on study morphometric and meristic characteristics of golden mullet (Liza aurata). 98 specimens were collected from catch of beach seine in the southern part of Caspian Sea. The mean body fork length, weight were measured 310.1±40.5 mm and 310.3±146.2 g, respectively. According to exponential length-weight relationship, growth followed isometric model (b=3.01). The mean age of golden mullet was 5.75 years (range 4-8 years). Statistical analysis of variance revealed significant differences between the means of samples for the number of second dorsal fin spines and also the number of anal fin spines in males and females (p < 0.05). The comparison of the results obtained in the Azerbaijan with this study indicates differentiation and geographical separation between these stocks in the most morphometric features and meristic counts.
