Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an aquarium for breeding live fish for breeding live fish in land facilities.

[0002]

2. Description of the Related Art In order to cultivate live fish and the like in land facilities, so-called live fish ikesu, live fish farms, live fish tanks and other live fish tanks are generally used. That is, this live fish breeding aquarium is intended to maintain the state of seawater in the optimum state and continue to provide a favorable environment for the fish bodies and bacteria in the aquarium.

By the way, in general, the method of purifying seawater in such equipment is carried out by a group of bacteria living in a filtration tank and a sterilizing device. That is, a group of bacteria oxidizes and decomposes organic impurities and the like, thereby purifying ammonia produced by nitrification, and further ammonia excreted from fish bodies is purified by nitrification to keep seawater clean. However, due to the material of the filter medium used in the filter tank, the size of the filter, etc., clogging occurs in a short period of time, and a passage for seawater can be created. On the other hand, at the site where seawater cannot penetrate, the fermentation process by anaerobic bacteria Caused the deterioration of seawater, which adversely affected the bacteria and fishes in the aquarium.

More specifically, there are a wide variety of materials for the filter medium in the filter tank, such as sand having a small caliber, coral, plastic, glass wool, etc., and the filter medium is multistaged in the filter tank. It was heavily sedimented and passed through seawater for filtration. As a result, in the above-mentioned filtration tank, after a short period of time, residual fatigue, vomit, feces, moss (persimmon, persimmon,
Scales, slimes (slides), bacterial carcass peeling film, dust, etc. cause clogging, and the resulting oxygen deficiency creates an anaerobic environment in the aquarium, which causes bacteria groups, fish, etc. to be hit, and thus the aquarium Inviting a decrease in the commercial value of fish in the
Depending on the situation, fish etc. were killed. In order to eliminate such a decrease in the value and death of the fish and the like bred in the aquarium, frequent replacement of seawater, cleaning of the filtration basin, etc. are required. However, by replacing seawater in a short period of time or frequently cleaning the filtration tank,
The generation, reproduction, and multiplication of bacteria that purify seawater become almost impossible, which makes it impossible to create or provide the best seawater environment for bacteria and fish in the aquarium. , This would shorten the survival time of fishes and the like. In addition, in order to solve this problem, installation of sterilization machine equipment etc. can be considered, but in that case, it will lead to a significant increase in equipment investment, and specialized technology will be required to maintain and manage such equipment. It was necessary, and this also increased costs.

Conventionally, as a method of moving seawater in a water tank, seawater is moved by a seawater pump. In that case, a faster flow velocity than is required in the entire water tank is created, and this fast water flow is generated. Flow flat in the aquarium and adversely affect the fish. In addition, in the method of moving seawater in the aquarium using a seawater pump, a stagnant place of seawater is generated at the bottom and corners of the aquarium, and the accumulation and accumulation of impurities proceed at this location, so the oxidation of impurities progresses. However, in an anaerobic environment, decay progresses and adversely affects seawater including bacteria and fish in the aquarium. It is part of the cause.

[0006]

In view of the above problems in the prior art, the present invention utilizes the water purification action of aerobic microorganisms, which is the action of purifying water containing seawater, to color seawater for a long period of time, It is an object of the present invention to provide an aquarium for raising live fish, which can prevent the rotten smell of seawater, frequent exchange of seawater, and frequent cleaning of a filter tank.

That is, according to the present invention,
In order to prevent seawater coloring, rotting odor of seawater, frequent replacement of seawater, and frequent cleaning of filtration tanks, the purpose is to purify seawater using aerobic microorganisms, which is the original function of seawater purification, and a gentle up and down exchange in the area inside the tank. By generating a circulating water flow, it is possible to reduce costs by eliminating the filtration tank, sterilization equipment, etc., which have been indispensable in the past, and to realize a significant reduction in maintenance costs. It aims to provide an aquarium, live fish farm, and an aquarium for raising live fish, including an aquarium for live fish.

[0008]

In order to achieve the above-mentioned object of the present invention, according to the present invention, the inner shape in the horizontal plane is a rectangular shape, and the inner shape is divided into planes to form a purification treatment tank and a foam. A tank and a breeding tank are formed,
The purification treatment tank and the foaming tank are formed at the same water level position, and the purification treatment tank, the foaming tank, and the breeding tank are arranged in a stepwise water level position, and seawater moves or circulates between the respective tanks.

An aquarium for live fish breeding is proposed, which is characterized by being conducted via a water conduit.

[0009]

In other words, according to the above-mentioned aquarium for raising live fish according to the present invention, a gentle up-and-down exchange circulation action is generated in the whole water in the breeding tank to expand the atmospheric contact area of water,
It keeps the dissolved oxygen content constant and makes it possible to eliminate stagnant areas of water. That is, it is possible to give a sufficient amount of oxygen to the fish and the like to be bred in the aquarium and to the bacteria group. This means that the fish have their own way of swimming due to the gentle up and down exchange circulation flow of water. The result is that the fish body is not subjected to exercise load due to forced water flow, stress is not applied to the fish body itself, it swims around actively, it becomes a healthy body itself, damage recovery is fast, and the best habitat is maintained. Will be able to continue. In addition, in the bacteria group, excrements excreted by fish and the like, residual food, vomiting, moss, exfoliated carcass membrane, garbage, etc.
Since it is always discarded outside the tank in a short time, the bacterial group does not have an extra load in the process of purifying seawater by the bacterial group, and the total amount of fish that is housed and raised and the excretion excreted from it. The balance of the cleansing action of the bacteria by the bacteria group is kept in balance. As a result, the ability to purify and recover water is fast, and the state of water in the best water tank that is colorless, transparent and odorless can always be created and maintained.
