Microfabrication processes have widely used as a method modifying the surface of materials. The surface processing is expected to use for the prevention of adhesions of marine organisms as a way without killing actions. In the developments of antifouling materials, it is important to achieve the quantitative evaluations of the adhesion characteristics between organisms and material surfaces. In this study, adhesion experiments were planned by using native species mussels on the surface-treated resin substrates located in an aquarium. And adhesive properties of the mussels were evaluated in the measurements of adhesion strength of byssus under tensile loading and observing the morphology of byssus. The effect of loading direction was investigated in the vertical and the shearing directions. Although the measured values of adhesion strength showed little differences in the surface conditions, the force on the shear direction tended to exceed the vertical direction in all substrate conditions. Adhesion marks of the byssus were found on the substrate surface after the tests. And, it was confirmed that the amount of the adhesion marks was different depending on the surface condition. The evaluation of adhesion was achieved in the loading experiments of byssus and in observations of the morphology of byssus.
