<p>PURPOSE:To prevent the damage for fish bodies by forming a fish collecting part on the intake side of an ejector part, connecting the water absorption port of a booster pump with a filter interposed, and communicating the discharge port of the booster pump to the nozzle of a transport pipe. CONSTITUTION:A fish collecting part 7 is formed on an ejector part 3, and the water absorption port 4a of a booster pump 4 is connected with a filter 6 interposed. And the discharge side of the pump 4 is communicated to the nozzle 3D of a transport pipe 2. In this constitution, due to the synergism of the water absorbing power of the pump 4 and that of the part 3, fish bodies A are collected in the part 7 to be absorbed in the pipe 2 from the part 3. At that time, the bodies A are surely sent to the pipe 2 with the filter 6 to be transferred in a net 12 by the jet of the nozzle 3D. This constitution enables the transfer of live fishes without damage for fish bodies.</p> |
