| 内容記述 | The burrowing behavior in Pseudogobio esocinus was ascertained based on the photographic and optical observation in the glass tank. The preference of the grainsize of sand or gravel of the fish was examined. The sand or gravel was divided into five sizes of diameter of 0.50-1.00, 1.00-2.00, 2.00-4.00, 4.00-6.73 and 6.73-7.93 mm. The action was taken in the following order; the fish sucked the sand in the bottom in the buccal cavity and exhausted it from the gill slits, put the head in the sand, lifted the tail with the horizontal opening of pectoral fins to the angle of 20° to 30°, and burrowed into the sand using the thrust force caused by the sweeping action of the tail. After finishing the burrowing, the head was kept in an upper position than the tail, and the pectoral fins were opened a little and the other fins closed. The time needed in burrowing was 3.0-4.5 sec in the case of a fish of total length of about 100 mm and 3.5-5.0 sec of the total length of about 130 mm. Eighty four to 92% of the individual number of the fish distributed on the sand bottom of the diameter of 0.50 to 2.00 mm and 33-100% out of them burrowed into the bottom. But little distributed on the gravel bottom of the diameter of 2.00-7.93 mm and none burrowed into the bottom at all. The fish of the total length of 80-160 mm and the total length of 50-80 mm burrowed mainly into the grain-size of 0.50-1.00 mm and the grain-size of 1.00-2.00 mm, respectively. | |||||
