The purpose of this study was to compare the Biomass variations of zooplankton in the eastern coast of Chahbahar in the summer and autumn seasons. Sampling was done using a 100-micron zooplankton net to horizontally in two summer (Monsoon) and autumn (Post-Monsoon) in 2015 at 8 stations. According to the results, the mean of dry weight of zooplankton was 115.46±16.34 and 23.45±2.26 mg m³ in autumn. Independent T test showed a significant difference between the seasons of summer and autumn in terms of biomass (P<0.05). There were significant difference of biomass in the sampling stations (P<0.05) at each seasons. The Maximum and minimum values of biomass recorded at Station 3 (Shipbuilding) and Station 8 (Out of the Beris Port) respectively. According to the results of one-way ANOVA, there was no significant difference of salinity and temperature between different stations in the summer and autumn seasons (P>0.05). Also, the transparency at station 3 was significantly higher than other stations in summer. According to the results of Pearson correlation, inverse linear relationship were observed between biomass and temperature (r=-0.796) and salinity (r=-0.285). Bay are affected by the monsoon and the western winds of the Indian Ocean. Zooplankton density is due to environmental, nutritional and reproductive conditions in different seasons should be.

Keywords: Biomass, Zooplankton, Chahbahar Bay, Makran Sea.
