Precious marine product aquaculture device suitable for shallow sea

The invention belongs to the field of sea farming, and particularly discloses a precious marine product aquaculture device suitable for shallow sea. The device comprises an uncovered cube plastic box (1), two cambered-surface-shaped plastic plates (2 and 3) and a sinking prevention hard plastic plate (4), wherein the cambered-surface-shaped plastic plates (2 and 3) are located below the uncovered cube plastic box, and the sinking prevention hard plastic plate (4) is located on the lower portion. Four steel pipes (5) are fixed to four corners of the uncovered cube plastic box (1), penetrate through the sinking prevention hard plastic plate located on the lower portion and enable the uncovered cube plastic box (1) and the sinking prevention hard plastic plate (4) to be connected into an integrated structure. A steel conical fixing head (6) of a hollow structure is welded to the bottom of each steel pipe (5), and the tip of each fixing head (6) is provided with two rows of round holes (7) arraying around a corresponding vertex. The device is simple in structure, greatly improves the survival rate of fry of precious marine products and is beneficial to mass application and popularization.
