Description

Applicable under Article 30, Paragraph 2 of the Patent Act. Published on May 28, 2021, in "Collection of Technical Support Results 2021, p. 20, Hokkaido Research Organization, Industrial Technology Center." Published on June 22, 2021, in "Summary of the Technology Transfer Forum 2021 Industrial Technology Center Results Presentation Meeting," which was published on the website. This invention relates to an attachment device for cultivating aquatic animals, and to a method for cultivating aquatic animals using the said attachment device. To prevent poaching and identify the origin of marine animals, technologies have been developed to apply tags that indicate the origin of shellfish and other aquatic animals. Examples include a method for identifying the origin of abalone by feeding them multiple seaweeds of different colors, thereby creating two or more striped patterns on their shells (see Patent Document 1); a shellfish tag characterized by the attachment of shell powder to the opposite side of the part of a clamping device that grips the periphery of a shell from both sides (see Patent Document 2); a method for forming a tag using rust generated by immersing a shell in water and reacting iron powder particles with oxygen in the water (see Patent Document 3); a method for marking shellfish by embedding a metal piece that serves as an identification piece in the ligament of bivalves (see Patent Document 4); and a method for forming a tag by chemically bonding a coloring substance to the shell surface so that the colored area does not spread to the newly growing parts of juvenile shellfish (see Patent Document 5). Furthermore, in the case of oysters, a representative species of bivalve mollusks, the shape of the attachment device used to cultivate oyster juveniles is being investigated to improve the efficiency of cultivation. For example, to improve oyster attachment, a disc-shaped oyster cultivation substrate with an attachment bed consisting of fan-shaped, grid-like, trapezoidal, or other polygonal peaks and valleys on its surface is known (see Patent Document 6). Also known are oyster cultivation attachment devices that are flat, plate-shaped bodies with multiple protruding spacers and fine irregularities on their surface to improve attachment (see Patent Document 7). Furthermore, as a technique to alter the shape of oyster shells to enhance their commercial value, a method for cultivating oysters with heart-shaped shells is known (see Patent Document 8). This method includes the step of cutting a V-shaped notch in the center of the growth end of the oyster shell, and then inserting and engaging a molding tool having a corresponding V-shaped tip into the notch to form a V-shaped depression.
