2526 specimens of the rock lobsters, Panulirus homarus were caught from Iranian seashores of the Oman Sea during November 1999 to November 2000. Samples were collected by plastic American traps from different fishery stationsat Ramin, Chabahar, Puzm and Meidani. Mean weight and length of the lobsters were compared by HSD Tukey test. Length classes of the lobster populations from different fishing sites were acquired using Bhattachrya method. Mean carapace length (mm) and body weight of the specimens were : 74/91×11.09 and 477.3×184.11 in Ramin, 82.57×10.07 and 425.63×155.98 in Chabahar, 71.49×15.33 and 384.69×199.5 in Puzm and 85.54×12.55 and 587.04×215.53 in Meidani, respectively. Results showed that mean weight and length of the lobsters were increased in Puzm, Ramin, Chabahar and Meidani, respectively. Also males had larger length and weight sizes than females. There were 3, 1, 2, and 2 length classes in the lobster populations of Ramin, Chabahar, Puzm and Meidani, respectively. Lobsters with 6.4- 8.2 cm carapace length were dominant in all fishing sites. The best dispersion of length classes was observed in Ramin.
