The present invention relates to a fishing tool for cultivating a non-adherent shellfish, and a cultivation method using the same. The fishing tool for cultivating a non-adherent shellfish comprises: a container body formed with a cultivation space having an open upper side covered by a sanitary net to accommodate a non-adherent shellfish in a state of filling a plurality of balls at a lower portion thereof； a drain formed at the lower portion of the container body； and a plurality of rope fixing holds provided on an outer surface of the container body to connect an underwater rope to place the container body under sea water. According to the present invention, a cultivation fishing tool stacked and installed in multiple stages is hung on the underwater rope to be drifted in the sea water so as to easily introduce the cultivation fishing tool into a water depth most suitable for non-adherent shellfish cultivation. Also, an optimal breeding environment is provided to remarkably increase the yield of the excellent non-adherent shellfish. In addition, a multi-stage stacking type structure is applied, such that the cultivation fishing tool is easily manufactured and installed and foreign competition in an aspect of costs can be secured. Furthermore, attachment of heterogeneous organisms or foreign substances is maximally suppressed to reduce costs required for maintenance of a cultivation device, and a large amount of non-adherent shellfish per unit area can be safely cultivated. Moreover, the practicality required for cultivation of the non-adherent shellfish, such as simultaneous production of various sizes of the non-adherent shellfish from a young shellfish to a grown shellfish, can be maximized even with one cultivation device.COPYRIGHT KIPO 2020본 발명은 비부착성 패류의 양성을 위한 어구로서, 개방된 상측이 위생망으로 덮이는 양성공간이 하부에 볼이 다수로 채워진 상태에서 비부착성 패류가 수용되도록 형성되는 용기본체； 상기 용기본체의 하부에 형성되는 배수구； 및 상기 용기본체가 해수 중에 놓이도록 수하로프를 연결하기 위해 상기 용기본체의 외측면에 다수로 마련되는 로프고정홀드；를 포함하는 비부착성 패류 수하식 양성 어구 및 이를 이용한 양식
