DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a circulating breeding apparatus for fish and shellfish, and more specifically, a plurality of breeding vessels for artificially breeding shellfish and fish are arranged in a single tank, and the tank is provided with the same. And a device for always maintaining the environment fresh.

[0002]

2. Description of the Related Art When seafood is artificially bred, seawater or freshwater (hereinafter referred to as "raw water") sent to a breeding container containing fry or larvae is used to excrete fish and shellfish,
It is contaminated by residues of the administered feed.

[0003] Therefore, it is desirable to always keep the inside of the breeding tank that contains the fish and shellfish in a fresh environment. For this purpose, the breeding container for the fish and shellfish should be placed in a water tank equipped with a filtering device or an aeration device. Has been done.

[0004] When various kinds of fish and shellfish are classified and accommodated in separate breeding containers, and the plurality of containers are placed in one large aquarium and bred, the growth or type of the juveniles or larvae is determined. It is convenient because it can be taken out according to the situation.

[0005]

When a large number of breeding containers are arranged in one water tank, it is uneconomical to attach a filtration tank or an aeration device to each breeding container. There are many disadvantages to maintenance or management.

[0006] In view of the above problems, a main object of the present invention is to provide a recirculation system for fish and shellfish which can always maintain a fresh environment inside a single aquarium in which a large number of fish and shellfish breeding containers are arranged. A breeding device is provided.

[0007]

In order to achieve this object, a fish and shellfish circulating breeding apparatus according to the present invention comprises a raw water storage tank, a filtration tank for purifying raw water in the raw water storage tank, and a plurality of fish and shellfish. A breeding tank containing the breeding container, a purified water pipe extending horizontally at the bottom of the breeding tank and having a fountain hole for the purified water, a contaminant reservoir provided at the bottom of the breeding tank, and water in the breeding tank. And a drain pipe provided with a siphon pipe device for returning a part of the raw water to the raw water storage tank.

DESCRIPTION OF THE PREFERRED EMBODIMENTS One preferred embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a schematic diagram showing a configuration of a circulating breeding apparatus 10 for fish and shellfish of the present invention, in which raw water stored in a raw water storage tank 12 is purified through a filtration tank 14, and the purified water is first purified water. Breeding tub 2 that stores a plurality of breeding containers 20 that store fish and shellfish, stored in the tank 16 and the second water purification tank 18
2, a contaminant reservoir 24 for collecting contaminants in the breeding tub is provided in the breeding tub 22, and the water supplied to the breeding tub 22 is returned from the breeding tub 22 to the raw water storage tank 12, so that the raw water is constantly circulated. It is configured in.

A conduit 28 having a first pump 26 is connected to the raw water storage tank 12 and the bottom of the filtration tank 14 for sending water in the raw water storage tank 12 to the filtration tank 14.
The purified water that overflows and flows out from the top is stored in the first water purification tank 16.

The first water purification tank 16 and the second water purification tank 18 are connected by a conduit 32 having a second pump 30.

The first water purification tank 16 has a conduit 3 provided with a third pump 34 at the upper part of the breeding tank 22 so as to discharge purified water.
6 is connected to the breeding tank 22.

The second water purifying tank 18 is connected to a water purifying pipe 42 extending in the longitudinal and horizontal direction at the bottom of the breeding container 20 via a conduit 40 having a flow control valve device 38. The water purification pipe 42 is provided with a plurality of fountain holes 44 at appropriate intervals on its upper side wall.

The flow control valve device 38 can be an electric automatic flow control device known per se, and the amount of water sent from the second water purification tank 18 to the breeding tank 22 can be adjusted as required.
It can be controlled to a desired amount.

It is preferable to provide a suitable shelf member 46 for disposing the breeding container 20 for storing larvae or larvae of bred fish and shellfish above the fountain hole 44 of the water purification pipe 42. As the breeding container 20, for example, an “abalone breeding device” disclosed in Utility Model Registration No. 3049278 can be applied.

A contaminant reservoir 24 is formed at a part of the bottom of the breeding tank 22 to collect contaminants such as fish and shellfish excreta or feed residue in the breeding container 20 disposed in the breeding tank 22. In order to discharge the water in the breeding tank 22, a siphon pipe device 48 having an inlet end is provided above the contaminant reservoir 24, and the siphon pipe device 48 has a drainage having an electric siphon control valve 54. Raw water storage tank 12 by pipe 50
Has been contacted.

In the circulating breeding apparatus 10 for fish and shellfish of the present invention, for example, a guide plate 52 known per se can be provided to guide the water flowing in the breeding tank 22 in a desired direction.

[0017]

[Operation and Effect] The circulating breeding apparatus 10 for fish and shellfish of the present invention
Is configured as described in detail above, after arranging the breeding container 20 containing a fry or shellfish of the seafood in the breeding tank 22, and after filling the seawater or freshwater via the raw water storage tank 12, The purified water filtered through the filtration tank 14 is supplied to the breeding tank 22 according to the operation of the second pump 30 and the third pump 34.

In particular, water is sprayed from a fountain hole 44 opened on the upper side wall of the purified water pipe 42 arranged at the bottom of the breeding tank 22 to the fish and shellfish breeding container 20 disposed above the fountain container. For example, when the breeding container 20 is the one described in Utility Model Registration No. 3049278, supra, the effect is further improved.

Further, if the purified water supplied to the breeding tank 22 is contaminated by fish and shellfish excreta contained in the breeding container 20 or residue of feed, etc., the sediment is contaminated by the contaminant reservoir 2.
4 and the water in the breeding tank 22 is constantly discharged to the raw water storage tank 12 in a very short time via the drain pipe 50 having the siphon pipe device 48. It can be maintained in a constant clean state.

According to the present invention, the amount of water sent from the second water purification tank 18 to the breeding tank 22 is controlled by the flow control valve device 38 twice a day, for example, together with the natural tide time.
The ebb and flow state is created in the breeding tank 22 by the siphon pipe device 48 and the electric siphon control valve 54, and discharge of contaminants can be easily performed by fluctuation of the water level of the breeding water.
