Abstract

The sexual dimorphism and intra sexual dimorphism in males of Rhinogobius brunneus wereinvestigated at Jiam stream, a tributary of the Bukhan river from May, 2005. The frequency distributions in standard length were similar for the females and maleLs, but maleSs were smaller than the females and maleLs. The ratio of MaleL (N= 79) to maleS (N= 79) was 1 : 0.46. The comparison between female (N= 79) and maleL (N= 79) gave significant differences (P<0.05) in 18 morphometric characteristics (SNL, AHD, PHD, ML, DL, MW, AHW, IFW, PHW, ED, HL, FDFL, SDFB, CFL, AFB, VFL, PFL, PFB) and 12 characteristics (SNL, AHD, ML, DL, MW, AHW, IFW, PHW, HL, FDFL, CFL, PFB) (PMW, HL, CFL, VFL, PFL) in female (N= 36) and maleS (N= 36) had significant differences (P<0.05) and three characteristics (ML, DL, HL) had very significant differences (P<0.001). Eleven characteristics (SNL, AHD, PHD, ML, DL. MW, AHW, IFW, PHW, HL, FDFL) were significantly different in maleL (N=36) and maleS (N=36) (P<0.05) and six (ML, DL, MW, AHW, HL, FDFL) were very significantly different (P<0.001).
