Journal Article 2017 09 23 The aim of this study was to determine the influence of environmental parameters on<br />the abundance of monkey goby Neogobius pallasi. A total of 526 and 163 individuals of<br />monkey goby specimens were caught by electro-shocker in the Kaboodval and Shirabad Streams, respectively. The ranges of total length of the specimens in Kaboodval and Shirabad Streams were respectively 22-137.55 mm and 32.64-137.97 mm. All the specimens of both streams belonged to the 5th age group (0+-4+). The morphological, hydrological, biological and physicochemical parameters were investigated in both streams. The results showed that the hydrological parameters and vegetation coverage in the Kaboodval Stream and also, water velocity and depth in the Shirabad Stream had significant relationship with the monkey goby abundances (P https://ijerr.gau.ac.ir/article_3704_b12fb6f6aefc3a5ac4daa8692ceee311.pdf
