Abstract
This study investigated find the respiration rate in accordance with the water temperature conditions and salinity by analyzing respiration pattern of philippinarum(Ruditapes philippinarum). We conducted to observe and record the flow of fluid by breathing in the target organism using PIV method. Philippinarum were placed in the experimental tank after stabilizing of water temperature and salinity. Recording was commenced when the tank flow was in static after putting particle into the tank. Laser generator was mounted on the side of experimental tank and camera on the front of the tank. the scattering of particles from the light source was recorded and the images were post-processed by software and analyzed results. At 15.1℃ and 27.0‰, the maximum turbulence intensity was 5,468×10SUP-6/SUP m/s. At 19.4℃ and 26.8‰, the maximum turbulence intensity was 26,357×10SUP-6/SUPm/s. Comparing the maximum turbulence intensity between the two experiments shows a difference of about 4.8 times.
