The common octopus (Octopus vulgaris) is considered a strong candidate for marine aquaculture due to its high growth rate and competitive market price. To investigate product potential, This study aims to investigate the moving patterns of common octopus between pipe and no shelter type up on changes of water temperature (10, 15 and 20℃). Experiments were conducted in a recirculation aquaculture system with dimensions of 2100 × 1000 × 1100 mm for 15 days (16 to 30 Nov, 2015). Three octopuses used in the experiment was 430 ± 21.6 g in body weight. Video cameras were set on the upper, front and inside of water tank and video camera footage were analyzed by PVS (private virtual studio) program.
The octopuses showed the highest activity at 20℃ of water temperature in no shelter condition and at 15℃ of water temperature in shelter condition. The maximum moving distance and speed of 29.80 m in no shelter condition and approximately 27 10-3m/s at 20℃.
