The paper reports the capture of an abnormal specimen of Raja clavata Linnaeus, 1758 measuring 400 mm DW andweighing 987 g. This cartilaginous fish was caught from Çandarlı Bay (Izmir) by a commercial trawler. This specimen hasnose and tail deformities due to caught with a piece of trammel net (i.e. ghost fishing effect) and this phenomenon wasdiscussed and commented.
