Problems solved by technology

Specifically, there is a problem that the amount of dissolved oxygen in the water decreases because the water tends to stagnate, and it is difficult to remove residual bait and excrement, making it easy to get sick

Embodiment Construction

[0027] like figure 1 and figure 2 As shown, the cultivating device 1 of the present invention is formed by stacking a plurality of circular petri dishes 2 into multiple layers and being accommodated in a cup-shaped water tank 3 whose lower part has a smaller diameter than the upper part. The central portion of the stacked Petri dishes 2 has a structure in which a circular tube-shaped central cavity 4 is formed from the bottom to the top in the water tank 3 .

[0028] Here, the Petri dish 2 is composed of four shell storage parts 2a divided into sectors in the circumferential direction, and a mesh body 2b such as a punched metal plate or a mesh filter is provided on the bottom surface of the shell storage part 2a. . Furthermore, by stacking the petri dishes 2 in the vertical direction, the arc-shaped recesses 2c of the petri dishes 2 are layered to define a circular tubular central cavity 4 on the central axis. Observation and harvesting can be easily performed by dividing ...

Abstract

Provided is a farming device whereby benthic organisms such as bivalves can be marketed in a constant amount at a low price and, furthermore, the number of organisms under farming per unit area can be increased by feeding fresh water flow and setting the environment to imitate the natural habitats of the organisms. A farming device wherein a plurality of dish type containers (2), which are dipped in a water tank (3) and serve as farming beds for benthic organisms (S) such as bivalves, are vertically stratified, and horizontal spaces (D1) are formed between a central cavity (4), which vertically penetrates through the thus stratified farming beds, and the individual farming beds connected to the cavity (4).

Description

technical field [0001] The present invention relates to an apparatus for cultivating benthic organisms such as bivalve molluscs, and more particularly to an apparatus for cultivating benthic organisms such as clams, meretrix meretrix, and clams that inhabit environments exposed to tidal currents. Background technique [0002] Bivalve molluscs, represented by clams, meretrix meretrix, clams, etc., are representative public fish and shellfish in my country (Japan), and are sources of marine protein that can be obtained at low cost by ordinary people. However, due to water pollution in sea areas and the reduction of sandy beaches and tidal flooding areas caused by revetment works along the coast, the amount of resources and catches is decreasing sharply. At present, although bivalve molluscs are cultured in various places to ensure the amount of resources and catches, most of the culture methods are to artificially scatter juvenile shellfish on the beach and cultivate them in a...
