Size selectivity of sorting grid was studied for Common pandora in the Gulf of Antalya. Trawling’s were carried out in October - December 2012, with a traditional bottom trawl net (600 mesh around the mouth). The fish totally retained in upper codend (catches) and bottom codend (escapes) were used to estimate the selectivity. Selectivity data analyzed as covered cod-end method by means of a logit function of Maximum Likelihood Method. The Kolmogorov – Smirnov test (KS – test) was applied in order to determine the difference between size groups of escapes and catches codends. The percentages of the total catch in terms of weight were 56% retained and 44% escaped. Mean L50 value of common pandora was calculated as 14.47 ± 0.27 cm. Total weight of common pandora caught in hauls was 29.937 kg. The results confirm that using sorting grid fixed mesh codend gave higher L50 value than size selectivity studies with different mesh size and shapes.
