This research was conducted with the aim of determining the biodiversity of Pertaran communities in three areas with mangrove cover and in 9 stations including one station in Gowatr Bay and 4 stations in each of Gowatr bay and Bahu Kalat on the eastern coast of Chabahar port. From each station, from the winter of 2019 to the fall of 2014, three sediment samples were collected seasonally for the separation and identification of sediments and one sample for the analysis of grain size and total organic matter of the sediments by Grab van Veen with a cross-sectional area of 0.028 square meters. In total, 12 genera belonging to 10 families were identified. Among the groups of the detected families of spionidae, the highest percentage of the average frequency with 13.70% was related to the Spionidae family. The survey of the density of the birds in total is 17800 ± 180 in the mentioned seasons, the average density of the birds in winter is 8720 ± 42 and the average density of the birds in the autumn is 9080 ± 181.63 in the mentioned seasons, the lowest average in winter is related to the Nereidae family: 0.5 600±67 and the most number was for Spionidae family: 1280±31.47 individuals in one square meter. The lowest average in autumn was related to the Nereidae family: 560 ± 32.65 and the highest to the Spionidae family: 1160 ± 62.94 individuals per square meter. The results of the parametric one-way analysis of variance test showed that the abundance of Pertaran communities in different seasons and stations had a significant difference (P<0.05) and the average abundance was higher in winter than in autumn. A positive and significant correlation was obtained between the parameters of total organic matter and sediment granularity with density. The low diversity and the low percentage of organic matter in the winter season show the negative effect of the winter monsoon on the biodiversity patterns of the wetlands of the Goater Bay and the decrease in turbulence and stress caused by waves and temperature along with the abundance of organic matter causes an increase in the diversity and predominance of species in It is autumn season.
