PROBLEM TO BE SOLVED: To solve such problems that the culturing of adhesion shellfishes such as abalone requires functions such as (1) not forming stagnation in a culturing water vessel, (2) not leaving feces and residual feeds in the culturing water vessel, (3) having a wide culturing area, (4) easily harvesting, (5) easily being cleaned, (6) monitoring the cultured shellfishes and water quality, (7) being inexpensive and utilizing already existing facilities as much as possible, etc. SOLUTION: This spiral type shellfish-rearing plate is provided by installing a spiral type plate having a down grade slope toward the central part of spiral rotation and also making a part having a radius of an optional distance from the rotation central part as a hollow part in an optional water vessel so as to create the function and environment required for the culturing of the shellfishes.
