(Çanakkale Onsekiz Mart Üniversitesi, 2019) Gül, Benal; Nemli, Egemen
Electronic tagging methods are used in many studies for aquatic life. By using this method which is also called telemetry it is possible to obtain animal-borne data. However, for the success of the study, it is very important to know the response of the animal to the attachment process steps and the attached device. This is particularly hard when used with cephalopods as they will tend to grab on to the device, pull at it and rip it off. This is why there is limited telemetry study on cephalopods. In this study, we have tried to observe the reactions of octopuses (Octopus vulgaris,-Cuvier, 1797) and squids (Loligo vulgaris,-Lamarck, 1798) to a data storage tag which is a kind of telemetry device. The purpose of this work is to determine the duration of the device being attached to the individual, changes in its behavior, reason for detaching the device, injury and possibility of the death of individuals. At the end of the study, and the residence time of the tag varied between 1-7 days and it was determind that the octopuses created wounds on their bodies in order to remove the tag. Squids can carry the tag for 1 week. For both species, no deaths were detected due to tagging, carrying. Also, after remove the tag, individuals survived.
