<P>PROBLEM TO BE SOLVED: To improve a survival rate in breeding larvae of fishes that are intractable species in seed production. <P>SOLUTION: The breeding water circulation fluidized system is used in breeding, keeping, and moving larvae in breeding of larvae of fishes that are intractable species in seed production, The breeding water circulation fluidized system for breeding, keeping and moving the larvae of fish species that are intractable in seed producing, and a method of breeding, keeping and moving larvae in breeding the fish species that are intractable in seed production using the same are comprised of a combination of a water tank 1 having a bottom surface in a round-bottomed (hemisphere), conical, or funnel shape and a downward water flow generating device 2. The water flow rising along a water tank wall from the water tank bottom is generated by abutting the downward water flow with the water tank bottom, thus a circulation flow is generated in the breeding water 3 at the water tank bottom. <P>COPYRIGHT: (C)2012,JPO&INPIT |
