This study investigates modifications and the net design of shrimp trawls in addition to their development process in Iskenderun Bay. Small sizes of traditional bottom trawl nets have been used for shrimp fishery since trawl fishery started in the region. Recently, cutting shape trawl imported from Arabic countries has been introduced by local trawl fisherman. However, they can neither manufacture the same design nor mend the nets. Finally they formed a different model trawl by trial and error method. These net plans designated as traditional net, cutting net shape net and combined net are given here according to the FAO standards, and their modifications and desings are compared. Although these nets have different design characteristics, two of them, namely traditional and combined nets are similar in their two seems and asymmetrical gear design feature. The third one namely the cutting net has four seems in wings.
