چکیده

This research was carried out in 2017 with the aim of studying and comparing the frequency of total length, weight and the weight-weight ratio of 60 Penaeus indicusshrimp in three areas of this species (Konarak, Brais, and Gwatr) in the southern coast of Sistan and Balochistan(located north of the Mokran Sea). According to the results, the average length and weight of this species in the Konarak area was 103.9 ±16.3 mm, 24.21±6.45 gr and 82.8 ±11.6 mm, 15.95±12.4 Beris and in Gwatr was 152.1±16.7 mm, 17.08 ± 4.8 gr. The results of the study of the length-weight relation and the regression equation obtained from the Konarak coastal samples were as, R2=0.87, W=3.549TL-12.55 in Beris R2=0.79, W=3.159TL-13.17 and in Gwatr R2=0.85, W=2.702TL- 24.03. Comparison of these parameters among the regions showed a significant difference in one way ANOVA test (P < 0.05). The results indicate that the population of this species in different regions is likely to have different biological conditions that require more detailed dynamical studies to confirm or reject the difference between the populations of Indian white shrimp at the studied sites
