Abstract: This study was carried out from September 2002-April 2003 in the Karatas Coasts (Iskenderun Bay). A total of 274 specimens were trawled by monthly sampling. The age of Upeneus pori was estimated by examining sagittal otoliths and it was found out that the age composition varied from 0+ to IV+ age classes. The mean total length and total weight values were calculated as 9.83±1.56 cm to 9.74±5.03 g and the calculated length-weight relationship was W = 0.0107*L2.9487. The von Bertalanffy growth parameters were L∞: 21.98 cm, K: 0.194 year-1 and to: -1.168 year. The instantaneous rate of total mortality (Z) was 5.24, the natural Mortality (M) was 0.46 and the Fishing mortality (F) was estimated to be 4.78. The Exploitation rate (E) was calculated as 0.91 using value of M and F. Therefore, the population of U. pori off Karatas coast of Iskenderun Bay was under the threat of overfishing.
