In this study, 2 species (Scorpaena notata, Scorpaena porcus) belong to Scorpaena genus were caught monthly by trawl surveys carried out between January 2005-July 2007 in İzmir Bay, in order to determine of morfometric and meristic characteristics and length-weigth relationships parameters. During the research period, 658 Scorpaena notata and 221 Scorpaena porcus indi-viduals were investigated. The lenght-weight relationship of fishes were estimated as W=0.0164*L3.074 (r2=0.960) and W=0.0209*L2.987 (r=0.993) for Scorpaena notata and Scorpa-ena porcus, respectively. As a result of student t-test (p<0.05), it was determined that the growth characteristics of S. notata and S. porcus are positive allometry and isometry respecti-vely in the bay. In addition, 19 morphometric measurements taken and 7 meristic characteristic were counted for 23 S. notata and 29 S.porcus individuals.
