Therefore, wild octopuses were reared in the transparent, perforated and caped polyethylene terephthalate (PET) pots (10 l). The assay was established as one free group rearing as a control (12.7 kg/m <sup>3 </sup> of stoking density) and two individual rearing groups as I1 and I2 (13.8 kg/m <sup>3 </sup> and 18.3 kg/m <sup>3 </sup> of stoking density, respectively). The individuals were fed mainly fresh or thawed fish at 5% body weight per day. The experiments lasted for 120 days. The acclimatization period of the octopuses lasted within 3-5 days in the individual rearing and 7-10 days in the free group rearing. The final survival rates were 100% for the control and I1 or 85.7% for I2 (P>0.05). Statistically, differences were not found among the growth or specific growth rates (between 0.5 and 0.6%/day for the trials) (P>0.05). The maximum density (30.7 kg/m <sup>3 </sup>) was obtained from the I2 trial. </span> </p> <hr /> <p style="text-align:justify;"> <span style="font-size:14px;"> <br /> </span> <br /> </p>}, number={4}, publisher={Ege Üniversitesi}, organization={TÜBİTAK}
