The present invention relates to an apparatus for winding a seedling thread for sea squirts, wherein a single worker can easily and readily rotate a rope alone to uniformly wind a seedling thread on the rope according to a body and physical strength of the worker, thereby allowing a user to efficiently perform an operation of winding a seedling thread. The apparatus for winding a seedling thread for sea squirts, which enables a seedling thread to which sea squirt larvae are attached to be wound in a lengthwise direction of the rope comprises: a main frame erected as the lower end thereof is fixed to the bottom; a motor frame connected to the upper end of the main frame to have an opened front side; a motor cover connected to let the back side thereof seal the opened front side of the motor frame; an electrical motor connected to the back side of the motor cover to be accommodated in the inner side of the motor frame, where an output shaft thereof penetrates through the front side of the motor cover to protrude; a main hook connected to the output shaft of the electrical motor to rotate together, to which one end of the rope is hooked; a sub frame spaced apart to face the main frame and erected as the lower end thereof is fixed to the bottom; a bearing unit installed and fixed to the upper end of the sub frame; and a sub-hook supported by the bearing unit to rotate and face the main hook, to which the other end of the rope is hooked, wherein the rope rotates together when the main hook rotates by driving of the electrical motor, thereby enabling the seedling thread to be wound in a lengthwise direction of the rope.본 발명은 1인의 작업자가 혼자서도 자신의 신체 및 체력에 맞추어 쉽고 용이하게 봉줄을 회전시키면서 종사를 일정하게 봉줄에 감을 수 있어 능률적이고 효율적인 종사 감기작업을 수행할 수 있는 멍게의 종사 감기장치에 관한 것으로서, 멍게유생이 부착된 종사를 봉줄의 길이방향을 따라 감기도록 하는 멍게의 종사 감기장치에 있어서, 하단이 바닥에 고정 설치되어 직립하는 메인프레임과, 상기 메인프레임의 상단에 결합되고, 전면이 개구된 모터프레임과, 후면이 상기 모터프레임의 개구된 전면을 밀폐하도록 결합되는 모터커버와, 상기 모터커버의 후면에 결합되어 상기 모터프레임의 내부에 수용되고, 출력축이 상기 모터커버의 전면을 관통하여 돌출된 전기모터와, 상
