In this study, effects of shelter, a very important subject in octopus culture, in adaptation to controlled conditions of capture-based adult E. moschata were investigated. The octopuses were sorted in three groups; Group B (white PVC tubes), Group S (black PVC tubes) and Group K (control group without shelter). During the experiments, natural sea water temperature (14.7 plus or minus 1.9 degree C), salinity (37 ppt, and natural photoperiodicity (38 degree 21'N, 26 degree 46'E) were used, and oxygen saturation level was kept above 80%. In the present study, first feeding and adaptation to controlled conditions in Group K occurred on the 2nd and 5th day of the experiment, respectively. First feeding in Group B and Group S were determined 4th day and 3rd day of the trial, respectively. Adaptation to controlled conditions in Group B and Group S was completed on 8th day and 9th day of the trial, respectively. During the period, no cannibalism and food competition were observed in any experimental groups. No statistically significant differences between the groups were found (p>0.05).
