Abstract: 

In this study, some biometric characteristics were studied in three lagoons, Almagol, Ajigole and Alagol in 2009-2010. Sampling take place monthly using collapsible traps (Funnel Trap). In this study the max 2310 male and 1779 female specimens and the lowest 594 male and 665 female specimens were in the Ajigol. In the three lagoons, females were smaller than males. Comparing the average mean length males and females showed significant difference among the Ajigol with the other lagoons and the Alagol with the other lagoons, respectively (P<0.05). In length-weight relationship, correlation coefficient was recorded as r=0.97 and r=0.96 for male and female, respectively. The growth pattern was minus algometric. Maximum CPUE value was 34.67 g/trap in spring, in the Alagol and minimum CPUE, 0.56 g/trap in winter for the Ajigol. However, invasive Macrobrachium nipponense shrimp into Golestan lagoons effect on their ecology and food web.
