This experiment was conducted to introduce the main families and identify the species of Pleuronectiformes on coastline of the Persian Gulf along Hormozgan province, from Gavbandi in southwest to Hormoz Strait. The study was carried out from March 2003 to June 2004.In this study, 329 fish were sampled. The fish were either caught by trawl or bought from the local fishmongers. The sampling was carried out in 9 different regions seasonally. Some 36 traits and parameters including 18 morphometric (measurable), 11 meristics (countable) and 7 apparent ones were determined. Analysis of morphometric data and dendrograms using cluster method and comparing the biometric data with the identification check list, it turned out that there were 6 main and dominant families including Citharidae, Bothidae, Soleidae, Psttodidae, Cynoglossidae, Paralichtidae in the area. In addition, the identification of above-mentioned families indicated that 15 species of such families are inhabiting the Hormozgan coastline of the Persian Gulf. The identified species are as follows:Brachirus orientalis, Parachirus marmoratus; (family Soleidae); Cynoglossus arel, Cynoglossus bilineatus, Cynoglossus puncticeps, Cynoglossus lachneri (Family Cynoglossidae); Pseudorombus elevatus, Pseudorombus arsius, Pseudorombus malayanus, Poecilopstei javanicus (Family paralichtidae); Arnoglossus aspilos, Arnoglossus arabicus, Laeopes guentheri (Family Bothidae); Psettodes erumei (Family Psettodidae) and Citharoides macrolepis (Family Citharidae).
