Therefore, if the horizontal positioning of the scallop 5 is performed with reference to the concave corner portion 5g, the through hole 6 can be formed in the one-piece portion 5c without fail. For this reason, as shown in FIG. 25 and FIG. 26, the apparatus for opening a single pin-shaped piece at the front end position of the cut-out ear side-to-side wall 34 in the shell section 21 is used for the right-side juvenile shell 5. The juvenile shellfish positioning part 91 is provided, and the juvenile shellfish 5 on the right side is positioned in the horizontal direction by making contact with the juvenile shell positioning part 91 so as to fit the concave corner portion 5g. As shown in FIGS. 27 and 28, a pin-shaped single-panel juvenile positioning unit 92 is provided at the front end of the ear side contact wall 37, as shown in FIGS. 27 and 28. The left juvenile clam 5 is positioned in the horizontal direction by making contact with the concave corner portion 5g so as to be fitted to 92. If the through holes 6 are formed immediately beside these juvenile shell positioning portions 91 and 92, the through holes 6 can always be formed in the single piece portion 5c regardless of the size of the juvenile shell 5. Accordingly, it is possible to promote the growth of the juvenile clam 5.

Further, the juvenile clam positioning portion 9 for opening one piece is provided.
A part or all of the shells 1 and 92 each have a shell part 21.
May be provided independently. That is, in another example shown in FIGS. 29 and 30, the single-sheet opening juvenile shell positioning portion 91 that positions the right juvenile shell 5 is formed by the shell seat portion 21.
And a single-opening juvenile shell positioning portion 92 for positioning the juvenile shell 5 on the left side is provided separately for the shell seat portion 21 and the above-described rope retainer 30a. Further, in this example, the right-side single-pane juvenile shellfish positioning portion 91 is formed in a block shape, and the concave corner portion 5g is fitted to the right-hand corner in front of the block-shaped single-pane juvenile shellfish positioning section 91. The right juvenile clam 5 is positioned in the horizontal direction by contact. Further, the left-side single-paneling juvenile positioning unit 92 is also block-shaped, and the block-shaped single-paneling juvenile-positioning section 92 is brought into contact with the left corner of the front side of the block-shaped single-paneling juvenile positioning part 92 so as to fit the concave corner 5g.
