P>Randall's threadfin bream, Nemipterus randalli, first recorded in Iskenderun Bay in Turkey in 2008, seems to have increased in the region. The species, widespread in the western Indian Ocean and with a rapid expansion, appears to have migrated to the bay via the Red Sea. Although its presence in the region has been published, there has been little or no information as to age and growth parameters of this Lessepsian migrant in its new habitat. The present study aims to determine the basic age and growth parameters of the species colonized in the region. A total of 379 collected individuals were studied from November 2007 to October 2008. Total specimen lengths ranged from 4.80 to 21.50 cm, and weights from 1.10 to 138.36 g. Maximum age was 3 years for both sexes. The length-weight relationship was described as W = 0.0011 x L3.061 (r2 = 0.982). The von Bertalanffy growth parameters were: L(infinity) = 34.96 cm; K = 0.214 year-1; t(0) = -1.244 year for the entire population. These data were compared with results from studies made in other geographic areas.
