DETAILED DESCRIPTION OF THE INVENTION The present invention will be described below with reference to the accompanying drawings. FIG. 1 shows a cannibalism-preventing raw fish transport container according to the present invention.
FIG. 1 is a perspective view showing an example, in which a flat box 1 having an open upper part is divided into a plurality of partitions 3, ...
It has a structure fractionated into

In the present invention, the vertical, horizontal and height dimensions of the inner method of each section are such that when two to five raw fish are accommodated in this section, each raw fish cannot turn. It is necessary to choose a range. Such a dimension is 1 in the longest direction, that is, in the vertical direction, based on the length of the raw fish.
It is within the range of 30%, 50% in the direction perpendicular thereto, and 70% in the height direction. Larger dimensions result in cannibalization, as the live fish contained can move freely. However, if the size is too small, deterioration of water quality in each compartment is accelerated, and metabolic activity is weakened due to restriction of exercise, which causes deterioration of freshness.
Therefore, the size of this section is usually 100 to 130% in length and 50 to 50 in width based on the length of the raw fish to be stored.
65%, 50-80% height range, for example 300m long
In the case of the squid of m, the length is 300 to 400 mm and the width is 15.
It is preferable to select in the range of 0 to 200 mm and the height of 150 to 240 mm. The thickness of the container and the partition plate is not particularly limited as long as it can withstand the mass of the cannibalized raw fish and seawater, but it is usually 3 to 10 m.
It is selected within the range of m.

As the material of the flat box 1 and the lattice-shaped partition plate 2 which compose the container of the present invention, wood, metal, plastic or the like is used, but fiber-reinforced plastic (in terms of light weight and high strength) FRP) is preferred.
Further, the grid-like partition plate 2 can be provided with circulation holes 4, ... For communicating the seawater of each section with each other.

The container of the present invention must be provided with a lid for suppressing the vertical movement of the stored raw fish and for preventing the raw fish from escaping from the upper opening.
This lid is composed of a perforated plate or a mesh. It is advantageous to form the bottom outer surface of each flat box forming the container so that it can be fitted into the upper opening of the flat box, because each container can be used by stacking a plurality of layers.
