Preferably, the box body is made of a non-toxic corrosion-resistant polymer material.

Due to the adoption of the technical scheme, the invention has the following beneficial effects:

by utilizing the benthic characteristics of the turbot, the turbot is cultured in a box-type culture unit with flat bottom and shallow water depth, the plurality of culture units are stacked by the characteristic that the culture units can be connected along the vertical direction, the three-dimensional space for culture is utilized to the maximum extent, the contradiction between the overlarge culture water surface requirement of the turbot and the limited area of an offshore platform or a cabin is solved, meanwhile, the culture units are arranged on the offshore culture platform, the specifications are unified, the culture units can be stacked in multiple layers, the stacked three-dimensional culture units are connected into a whole through a top horizontal connector, the end parts are fixed on the platform or a ship structure when the culture unit is used, therefore, the problem that the gravity center of the three-dimensional culture device is too high and the culture unit overturns due to shaking caused by the offshore environment such as external storm and current is solved, the turbot culture is possible from the bank to the deep and long sea, and the ship-borne three-dimensional culture of the turbot in the long sea is realized.

The bottom surface of the box body is flat and inclines downwards from the first end of the box body to the second end of the box body, so that the sediment in the box body can be conveniently flushed by water flow into the dirt collecting groove, and the sewage discharge port is used for discharging feed residues or fish feces out of the box body; the water inlet is arranged at the bottom of the first end of the box body, the water outlet is arranged at the upper part of the second end of the box body, and water can be drained through overflow to form water circulation. The support column plays the supporting role, and the convenient range upon range of detachable connection of two culture units about can realizing is dismantled in the adoption of first grafting structure and second grafting structure.

The horizontal connector is arranged at the top of the stacked culture unit group, can connect the culture units into a whole in a three-dimensional manner and is fixed on the shipborne culture platform to prevent the culture units from shaking and overturning.
