| 内容記述 | Experiments on rheotaxis and tolerance to oxygen deficiency of the Japanese mantis shrimp Oratosquilla oratoria were carried out in the laboratory as they may control the spatial pattern and the stock of the animal in some fishing grounds. An individual was entered the inlet of the center of the experimental waterway, diameter 110 mm and length 4150 mm, with 6 cm/s or 12 cm/s in current velocity, and its rheotaxis was judged from both the current direction and the position of the outlet where the animal exited the experimental waterway. All large sized shrimps, 10 males and 10 mature females, larger than 28.8 mm in carapace length showed negative rheotaxis at 12 cm/s. Positive rheotaxis was observed for only two small males 13.9 mm and 15.0 mm in C. L. at 6 cm/s. These suggest that negative rheotaxis becomes dominant with increasing current velocity and/or body size. Its migration in Ishikari Bay was analyzed based on these results. Behavior of animals in a sealed transparent aquarium and degree of oxygen saturation in the aquarium were periodically observed at 20℃ or 25℃. Animals became inactive in O: Sat. levels of 64.3-9.1%. Fast waving of pleopods occurred in O: Sat. 39.4-16.2%. Lying animals under paralysis which were unable to pick themselves up occurred in O: Sat. levels of 11.1-7.9%. Asphyxia was caused in O: Sat. levels of 11.1-4.5%. The resting oxygen consumption rates were 0.094 and 0.168 mg/h/g at 20℃ and 25℃, respectively. The level of no excess activity were 32.1 and 37.8% at 20℃ and 25℃, respectively. The results indicate that the low oxygen saturation levels of the bottom water in September in the eastern part of the Sea of Hiuchi Nada, the Seto Inland Sea, have marked physiologically effects and is a factor leading to the reduction in stock of O. oratoria in it. |
