The aim of this study was determine the selectivity properties of trammel net which have 100, 110, 120, 130 and 140 mm mesh size for Cyprinus carpio in Manyas Lake. Fieldwork was carried out in two different stations of Manyas Lake, in a monthly period from April 2007 to March 2008 and with a total of 24 catching trials. The SELECT method was used to determine the selectivity parameters. In the experiments, 208 C. carpio with length ranges between 28.4-65.4 cm were caught. According to the Lognormal model, the optimum total lengths were determined as 39.05, 42.95, 46.85 and 50.76 cm for 100, 110, 120, 130 and 140 mm mesh sizes respectively. As a result, in terms of the length at first maturity and legal status, the mesh size of nets used for C. carpio catching in Manyas Lake should not less than 120 mm.
