no. 1 approach

[0111] figure 2 A schematic diagram showing a first embodiment of the cage of the present invention. figure 2 denotes a cylindrical cage 10 . The cage 10 is constituted by using mesh woven cloth of a mesh sheet of 4 mesh or more for the side part 1, and the top surface is an opening part 3 in a perforated state. The bottom portion 2 is made of a woven fabric having a coarser mesh than that of the side portion 1 and has voids smaller than 4 meshes. Inside the cage 10, cephalopods can be maintained in a living state.

no. 2 approach

[0113] image 3 A schematic diagram showing a second embodiment of the cage of the present invention. image 3 It is the cage 11 on the top surface side of the side surface part 1 which shows the structure which provided the return part 4 on the square column. The side part 1 and the return part 4 on the top side are formed using a woven fabric with the same mesh. The upper end side of the return part 4 of the cage 11 is not closed, and the top surface is an opening 3 in a perforated state, so that it is easy to carry out bait input and the like. As in the first embodiment, the base 2 has a void of less than 4 meshes. In this second embodiment, the upper end of the side part 1 and the upper end of the return part 4 are respectively fixed and suspended on the wall of the extending direction (direction W of the arrow in the figure) of each sling and the tank wall of the breeding tank by the sling 5 to adjust The shape of the cage. At this time, the return degree of the retur...

Embodiment

[0116] The present invention is described in further detail below through examples, but the present invention is not limited to the following examples.

[0117] by image 3 The shown second embodiment was used as a reference, and the cage (A) was produced according to the following structure.

[0118] Side part: Using a 50-mesh polyethylene woven cloth (white), a cage having a square columnar side part with a width of 65 cm and a height of 70 cm was produced.

[0119] Bottom: Use triangular mesh polyethylene woven cloth to set a square columnar bottom.

[0120] Return part: Set the return part using the same fabric as the side part. The length of the return part is designed to be 20cm. When the state is suspended and stretched, the inferior angle of the angle formed by the return part and the side part ( image 3 θ1) is 160 degrees.

Abstract

The purpose of the present invention is to provide a cephalopod breeding basket or a cephalopod escape preventing sheet, which can keep cephalopods in a viable state and be used for cultivating, domesticating, displaying, transporting, and storing cephalopods, and prevents cephalopods from escaping. Provided is a cephalopod breeding basket (10) that can keep cephalopods in a viable state and is configured such that a net-shaped sheet having a mesh number of at least four is used in at least a portion (a side surface section (1)) thereof. Also provided is a cephalopod escape preventing sheet that can keep cephalopods in a viable state and is configured such that a net-shaped sheet having a mesh number of at least four is used in at least a portion thereof.

Description

technical field [0001] The present invention relates to a cage for raising cephalopods and a sheet for preventing cephalopods from escaping, and their use, wherein the cephalopods can be maintained in a living state. Background technique [0002] In order to provide a stable supply of food resources, the cultivation techniques of various aquatic organisms are being actively developed. However, although cephalopods such as squid and octopus have been deeply involved in the dietary life of the Japanese, their farming techniques have not been established. [0003] For example, the importance of the culture environment when raising octopuses is also pointed out, and various structures using octopuses under cultivation are proposed (Patent Documents 1 and 2, Non-Patent Document 1).
