A WAY TO RAISE RANCHU ● CULLING ROUND - IV

Fourth Culling Round - Three And A Half Month After Hatching

The ranchu size should be reaching 2 6/8 in (70 mm). During this round look for overall quality of the ranchu. All faults previously not noticed will be obvious now. Tail tension that looked good before could have weakened. Tail peduncle plate (osara) must be strong and fully developed at this time to support the tail tension.

Physical strength in some fish might have faded and will be recognized during this round.

Previous selections where made to recognize faults and deformities that could be harmful or fatal to the fish in one way or the other. This round is to recognize fish potentials for the future. Big attention is given to the tail tension, right and left symmetry of the body, swimming ability and overall development. Preparing the fish for its 5th last and most demanding round. The number is reduced from 2/3 to up to a half.
