This study was conducted on population dynamic of Periophthalmus waltoni by using length frequency data of 1225 specimens of this species that were collected by hand and dip net from mangrove forest khamir port in the hormozgan province during September 2015 to June 2016. Growth of parameters were estimated using ELEFAN programmer of FiSAT II software. The growth parameters of von Bertalanffy equation were estimated as: L: 13.75 cm and K: 0.68 year -1 t0: -0.29 for males and 13.75 cm and 0.51 year -1 t0: -0.39 for females. The mean length of P. waltoni specimens caught in the study area 8.92±0.05 cm for males and 9.05±0.06 for females. The weight means for males and females were 7.27±0.13 gr and 7.68±0.17respectively. The b was 2.91 and 3.04 for male and female. The length-weight relationship for males and female were W=0.0114 L2.911(r2=0.957) and W=0.0087L3.041 (r2=0.955) respectively. Maximum age was estimated to be 6+ years. Tow chohorts were distinguished. The maximum recruitment was in April at 22.33% for males and in July at 13.97 for females. The natural mortality coefficient was 1.58 and 1.4 in female and male.

Keywords: Age and growth, Periophthalmus waltoni, Persian Gulf, Hormozgan province.
