Abstract

PURPOSE:To facilitate the prepn. of artificial sea water and to stabilize the water quality over a long period of time with the above preparing agent for breeding fishes, etc., by adding and mixing BAKUHANSEKI (sliceous stone produced in Japan) powder to and with an aq. soln. of artificial sea water components. CONSTITUTION:The thick aq. soln. is prepd. by dissolving about 30 to 100 pts.wt. generally commercially marketed artificial sea water components (solid), such as sodium chloride, in 100 pts.wt. water and is prepd. to the salt concn. meeting the species of living things as necessary. The BAKUHANSEKI is added thereto preferably ad 1 to 10wt.% although the compounding ratio is not particularly limited. The BAKUHANSEKI powder may be previously compounded with the powder of the artificial sea water components. The harmful components, such as ammonia and sulfurous acid, generated according to breeding are non-polluted if the artificial sea water preparing agent compounded with the BAKUHANSEKI powder in such a manner. In addition, the propagation of the aerobic bacteria is accelerated by the neutralization of the pH and the increase in the quantity of the dissolved oxygen by the elution of oxygen. Further, the stains, smells and microorganisms of the sea water can be absorbed and removed as well by the BAKUHANSEKI powder.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is mainly for preparing artificial seawater for breeding various fishes inhabiting seawater, crustaceans such as crabs and shrimps, anemones and other invertebrates in an aquarium. It relates to an artificial seawater preparation used.

[0002]

2. Description of the Related Art Needless to say, seawater is required for breeding seawater organisms in an aquarium. However, artificial seawater has been widely used as a material for easily preparing this seawater. This artificial seawater element is a mixture of dissolved components in natural seawater consisting of sodium chloride, magnesium chloride, sodium sulfate, potassium chloride, calcium chloride, and other trace components in a powder state according to its abundance ratio, By dissolving it in water, it is possible to prepare artificial seawater having a salt concentration according to the type of marine organism.

In the breeding of saltwater fish, which is generally practiced at present, artificial seawater is dissolved in tap water to have a specific gravity of 2.8-.
While adjusting to 3.0 Baume, the specified water temperature (usually 25
It is common to set the temperature to about 26 ° C), add various commercially available bacterial elements, and allow the water to adapt to the water for several days to a week without adding fish, and then add the fish and feed. At the start of this breeding, ammonia is generated in the water due to decomposition of the feed, excrement, etc., and its concentration increases with the passage of days.

However, as is well known, this ammonia is extremely toxic to saltwater fish, and even a trace amount of it greatly affects the fish body, so that with increasing concentration, some fish weaken and die, especially after the start of breeding. Weeks to 10 days are the most dangerous, and the larger the number of fish, the earlier the effect will appear. Furthermore, with the generation of ammonia, bacteria that decompose it and convert it to nitrite (NO ₂ ) grow, but this nitrite is also toxic to fish and usually cannot be tolerated at a concentration of 1 mg / l or more, The increase in conversion above does not mean that the danger is gone. That is, the seawater suitable for breeding could be adjusted only after the nitrous acid was stably and continuously converted into nitric acid by the aerobic bacteria.

[0005]

Therefore, in order to adjust a suitable breeding seawater, the nitrite concentration is constantly checked, frequent water changes are carried out to reduce the concentration, and aerobic bacteria are aerated. However, in general, this adjustment may take several months depending on the condition of the aquarium, and it takes a lot of time and the number of fish that will die will increase. At this stage, most of the beginners experience the difficulty of breeding saltwater fish and give up breeding.

[0006] Furthermore, it is difficult to maintain a good breeding seawater once it has been adjusted, it is necessary to monitor the concentration of ammonia and nitrite, and the water quality deteriorates quickly and water must be changed in a short period of time. I have to. In addition, in order to avoid the risk of ammonia and nitrous acid, it is not possible to increase the number of breeding tails per constant amount of water, and for this reason, especially when breeding a large number of seawater organisms at pet shops etc., the number of aquariums is increased and a large space Need.

On the other hand, abundant oxygen is required to grow aerobic bacteria in a saltwater fish tank, and if this oxygen is insufficient, the growth of anaerobic bacteria will be promoted and the water will become increasingly unfit for breeding. The aeration is capable of generating a large amount of fine bubbles, and as a filtering device, a large filtering tank having a high filtering capacity is required for the size of the water tank, which results in a high equipment cost.

In view of the above situation, the object of the present invention is to easily adjust the seawater suitable for breeding seawater organisms, and to maintain a good water quality condition for a long period of time stably. In addition to significantly improving the survival rate and habitation period of organisms, it is possible to reduce the frequency of water change, increase the number of breeding tails per constant amount of water, and use a highly efficient aeration and filtration device. It is to provide an artificial seawater preparation that is not needed.

[0009]

In order to achieve the above object, the first artificial seawater preparation according to the present invention has a structure in which barley stone powder is added and mixed to an aqueous solution of an artificial seawater component. The second artificial seawater preparation has a composition in which barley stone powder is mixed with the powder of the artificial seawater component.

Further, in the present invention, a preferred embodiment is a construction in which the amount of the barley stone powder used in the first and second artificial seawater preparations is in the range of 1 to 10% by weight based on the artificial seawater component.

[0011]

DETAILED DESCRIPTION OF THE INVENTION Detailed Description of the Invention The function of the present invention is that the boiled stone contained in the artificial seawater preparation of the present invention is a very porous mineral belonging to the quartz porphyry in igneous rocks, and has a pale yellowish brown to brown color. It has an appearance similar to barley rice with white phenocrysts of quartz and gray crystals of quartz scattered in the pale gray stone base, and it is produced in Kamo-gun, Gifu prefecture in Japan. However, this bakuhanishi has been used in the form of fine powder for a long time as a herbal medicine, etc., and it has been confirmed that it exhibits various medicinal effects even in modern times.

The first artificial seawater preparation of the present invention is an aqueous solution of an artificial seawater component, and the second artificial seawater preparation is a powder of an artificial seawater component mixed with the above-mentioned barley stone powder. Yes, the former can be diluted with an appropriate amount of water, and the latter can be dissolved in an appropriate amount of water to prepare seawater for breeding according to the type of seawater organism. This seawater is turbid at the beginning because it contains barley stone powder, but it becomes clear immediately in a short time by the operation of a simple filtration device used in a normal breeding aquarium, and can be immediately used for breeding seawater organisms.

However, when, for example, a saltwater fish is bred with the saltwater prepared by the artificial saltwater preparation of the present invention, it is surprising that the saltwater nitrite concentration in the water is the same as that of the saltwater fish in the past, and even the freshwater fish is almost completely destroyed. Even if it reaches a high level such as 1 mg / l or more, the fish are not much harmed and can swim well and eat well, and aerobic bacteria rapidly grow at a very early stage from the start of rearing, The nitric acid concentration is reduced by conversion to nitric acid, the water quality suitable for breeding is naturally adjusted at an early stage, and the good water quality lasts for a long time, and it is unlikely to cause stains or odors and maintains high transparency. The number of water changes can be greatly reduced.

Therefore, if this artificial seawater preparation is used,
It is extremely easy to breed seawater organisms such as saltwater fish, and even beginners can breed for a long time with almost no failure from the beginning of breeding, and the labor such as water change and cleaning is significantly reduced,
As for aeration and filtration equipment, there is no need for exceptionally high performance or large equipment, and equipment costs are reduced accordingly.

Further, as described above, since the influence of the nitrite concentration is very small, there is an advantage that the number of rearing seawater fish etc. per constant water amount can be increased. This is convenient not only for improving breeding efficiency and space efficiency in pet shops, but also for avoiding killing due to competition between fish. In other words, saltwater fish generally have a strong sense of territory and there are many conflicts among the same species.For example, susumedai fishes have a strong fighting spirit and quarrel quickly, always fighting, weak fish and those with poor physical strength are attacked. It is often hurt and killed, but this conflict can be prevented considerably by increasing the number of fish in the tank and weakening the territory consciousness. However, such a means could not be employed conventionally because the number of tails cannot be increased due to the problem of ammonia-nitrous acid.

On the other hand, according to the artificial seawater preparation of the present invention,
Most of the saltwater fish can be reared even if the salt concentration of the seawater to be prepared is lowered. That is, in general preparation of artificial seawater, the Baume degree is set to about 2.8 to 3.0, but when the artificial seawater preparation of the present invention is used, it is not necessary to have a high salt concentration as described above. It is possible to cultivate saltwater fish at a Baume degree of around 1.0 or less without any danger, and it is also possible to dilute salt concentration to mix saltwater fish and freshwater fish. There is an advantage that the amount is small and economical, and the amount of salt dripping outside the water tank is very small.

The various excellent advantages as described above are brought about by the barley stone powder incorporated in the artificial seawater preparation of the present invention, and the action is mainly based on the porous structure and multi-material composition peculiar to barley stone. It is supposed to be. That is,
It is confirmed by electron micrograph that barley stone is a very porous mineral, and the particles themselves have a sponge-like porous structure even in the form of fine powder. A unique multi-material mineral containing a large amount of various components such as magnesia, potassium oxide, sodium oxide, lime, ferrous oxide, ferric oxide, titanium oxide, phosphoric acid anhydride, and manganese oxide in small amounts together with compounded water and attached water. However, since it is porous and has a very large surface area, it exhibits a high adsorption power, and it has the property of eluting various minerals and oxygen in water and neutralizing PH. By the correlation of elution, it shows a water quality regulating action for keeping the amount of dissolved components in water such as minerals within a certain range.

Although the detailed mechanism of action of seawater prepared using the artificial seawater preparation of the present invention is unknown,
Hazardous components such as ammonia and nitrous acid generated during the breeding of seawater organisms are detoxified by the adsorbing action of barley stone powder and other physical or chemical actions, and dissolved by neutralization of PH and elution of oxygen. It is considered that the increase of oxygen content promotes the growth of aerobic bacteria. The pH at normal seawater concentration is a weak alkaline region of about 8.0 to 8.3, which is a factor that makes it difficult for aerobic bacteria to grow, which is generally said to grow faster in the neutral region. There is.

Furthermore, in seawater prepared with this artificial seawater preparation, dirt and odorous components are adsorbed on barley stone powder, and the microorganisms that are the source of these components are also adsorbed and their activity is hindered. Since the above water quality adjusting action is exhibited, good water quality with high transparency is maintained for a long period of time, and water is activated by elution of minerals and oxygen, so that the health and vitality of seawater organisms are maintained. It is estimated that high survival rate and long life period can be achieved.

The artificial seawater component used in the artificial seawater preparation of the present invention may have a composition ratio close to that of a dissolved component in natural seawater, and any powder mixture commercially available as a source of artificial seawater can be used. Can also be used. The main components of this artificial seawater include sodium chloride, magnesium chloride, sodium sulfate, potassium chloride, calcium chloride, sodium hydrogen carbonate, potassium bromide, boric acid, ammonium chloride, potassium phosphate, etc. Also, various trace components other than these can be appropriately blended.

The blending amount of the barley stone powder in the artificial seawater preparation of the present invention is not particularly limited, but both the first and second artificial seawater preparations are usually 0 with respect to the above-mentioned artificial seawater components. The range of 0.5 to 10% by weight, particularly 1 to 5% by weight is preferable. If the amount is too small, the above-mentioned action and effect are not sufficiently exhibited. It is uneconomical because it requires high material cost.

The first artificial seawater preparation of the present invention is
It is a liquid form in which barley stone powder is blended in an aqueous solution of an artificial seawater component, but since it is possible to adjust the salt concentration according to the species by dilution, the artificial seawater component (solid) is 30 to 100 parts by weight of water. It is preferable to prepare a concentrated aqueous solution in which about 100 parts by weight is dissolved. In addition, various bacteria, wound preventive and therapeutic agents, nutritional supplements and other additives can be added to both the first and second artificial seawater preparations as needed.

The artificial seawater may be prepared by adding an appropriate amount of tap water to both the first and second artificial seawater preparations and setting the required salt concentration. Although the suitable range of this salinity differs depending on the marine organisms to be raised, it is about 0.5 to 1.2 Baume for ordinary saltwater fish and 1.2 for invertebrates such as anemones and crustaceans such as shrimp and crab. ~ 1.5 Baume is enough. As a matter of course, the breeding cost is high, but the salt concentration closer to that of natural seawater does not hinder the breeding of these marine organisms. When saltwater fish and freshwater fish are mixed, it is preferable that the Baume degree is about 0.2 to 0.8, although there is a difference depending on the fish species.

The water temperature during breeding is usually set to about 25 to 26 ° C., but it has been found that a variety of saltwater fish breeding can be carried out at a high temperature of 28 ° C. or higher,
This is also an advantage of the artificial seawater preparation of the present invention. As described above, the water change may be performed at an extremely low frequency as compared with the conventional one, and may be performed at a time when a large amount of nitrite is generated, and the water change of 1/3 is sufficient. Usually, the same water can be used for a long period of 2-3 months.

Further, the artificial seawater preparation of the present invention is not limited to seawater used for aquariums for appreciation, but can also be used for preparation of seawater for commercial fish tanks containing fish, shrimps, crabs, shellfish, etc. It can also be used for rearing seaweed.

From the start of the breeding of the above-mentioned saltwater fish, tap water is replenished only for natural evaporation without changing the water to maintain the water level,
At 30 days after feeding twice a day, nitrite was not detected at all and PH was 7.5. This non-detection of nitrite is considered to be the result of faster growth of bacteria that convert nitrite to nitric acid because the filtration capacity is higher than in the water tank specifications of Example 1.
And the transparency of the water was very high and all fish were healthy, lustrous and prey-friendly. Furthermore, all fish continued to survive healthy for more than 3 months after the start of breeding, no fish were weak or died, and the nitrite concentration was 0.1 mg /
It has remained at a low value of 1 or less.

Example 3 The same liquid artificial seawater preparation as in Example 1 was diluted with tap water to prepare 25 liters of artificial seawater having a salt concentration of 1.0 Baume, which was placed in a water tank having the same specifications as in Example 1. After the water was clarified by operating the filtration apparatus and 30 water was clarified, 30 damselfishes (body length: about 2 cm) were added and a breeding test was conducted at a water temperature of about 25 ° C. From the beginning of this breeding, tap water was replenished only by natural evaporation without water change to maintain the water level, and the feed between the fish was fed twice daily until 30 days had passed, and the fight between the fish was slight. There were no dead fish in the tail, and the water remained highly transparent.

From the start of the breeding, tap water was replenished only for natural evaporation without changing the water, the water level was maintained, feeding was carried out twice daily, and 30 days later, nitrite was completely detected. However, PH was 7.2, which was almost neutral water. The transparency of the water was very high, and there was no dead fish in either saltwater fish or freshwater fish. Both were healthy, had good color and luster, and had good aquatic plants. Furthermore, all the fish have survived more than 3 months after the start of breeding, and no fish have weakened.

Example 5 An artificial seawater preparation comprising a powder mixture of 300 parts by weight of artificial seawater component powder (same as in Example 1) and 10 parts by weight of barite stone powder was used, and this was added to tap water and mixed. An artificial seawater with a salinity of 1.0 Baume was prepared. Then, this artificial seawater was placed in a commercial water tank having the following configuration, the filtration device was operated for 24 hours, and then the following saltwater fish was placed in this water tank for breeding. The breeding starts in the winter (December).

The size of the water tank 120 cm x 45 cm
* 45 cm Water amount 210 liters Filtering device A large filter tank (60 cm x 45 cm x 45 cm) containing 4 kg of granular zeolite was provided, and SQ-10 (New Flower manufactured by Mizusaku Corp. as in Example 2) was used as an auxiliary in the water tank. Uses a filter connected. Floor sand in aquarium Fine silica sand Approximately 10 kg Water temperature 26 ° C in winter, 30 ° C in summer Input fish Medium length butterflyfish, etc. body length approx. 1
In addition to 3 to 5 medium-sized sea fish of about 5 cm at all times, about 10 to 20 small seawater fish such as small butterflyfish, squirrels and cobalt sparrows at all times, and always 2 to 5 freshwater fish such as grammy, plati, and barritus.

From the start of this breeding, tap water was replenished only for natural evaporation without changing the water once to maintain the water level, and the breeding fish were sold and new incoming fish were introduced while continuing feeding twice a day. During the period up to 6 months, a small number of newly arrived small fish died only 2 to 3 days after the introduction, and there were no other problems. It is probable that this dead fish had already been damaged or sick at the time of arrival.

At the time of the above 6 months, however, the nitrite concentration was 0.1 mg / l or less and there was no problem in water quality, but the nitrate concentration was high, so the first water change I went. For this water change, with the breeding fish still in the aquarium, use a hose to draw 1/3 of the total amount of water from the bottom of the aquarium, supplement tap water to match this, and then use the same artificial seawater preparation as above. In addition, the Baume degree was adjusted to 0.8. Two small fish died within a few days from the time of this adjustment, but there were no other problems, and no dead fish came out until the second water change three months later.

The second water change (9 months after the start of breeding) was carried out in order to respond to the new arrival of saltwater fish sensitive to water quality, and 1/3 of the total amount of water in the same manner as the first time. Was removed, and tap water and an artificial seawater preparation similar to the above were added to adjust the Baume degree to 1.0. However, no dead fish occurred after this water change, and all the fish are alive and healthy. It should be noted that, including this second water change, the bed sand in the aquarium has not been washed by agitation since the start of breeding, and the filter medium in the filtration tank has not been washed with the initial water filling. The transparency of No. 1 was continuously good, and there was no problem as a commercial water tank.

EFFECT OF THE INVENTION According to the artificial seawater preparation of the present invention, a liquid form can be diluted with an appropriate amount of water, and a powder form can be dissolved in an appropriate amount of water. It is possible to prepare artificial seawater for breeding according to, and even if the prepared artificial seawater reaches a high concentration of nitrite at the early stage of breeding that can not be tolerated by freshwater fish in the past, there is very little harm to fish and Since aerobic bacteria rapidly proliferate at a very early stage from the start and the water quality suitable for breeding is adjusted early and naturally, and the good water quality lasts for a long period of time and does not generate dirt or odor and maintains high transparency. The number of water changes can be greatly reduced compared to the conventional case.

Therefore, if this artificial seawater preparation is used,
It is extremely easy to breed seawater organisms such as saltwater fish, and even beginners can breed for a long time with almost no failure from the beginning of breeding, and the labor such as water change and cleaning is significantly reduced,
As for aeration and filtration equipment, there is no need for exceptionally high performance or large equipment, and equipment costs are reduced accordingly. In addition, as described above, the effect of nitrite concentration is very small, so there is an advantage that the number of breeding tails of saltwater fish etc. per fixed amount of water can be increased, and this will only increase breeding efficiency and space efficiency in pet shops etc. Not only that, it becomes possible to weaken the territory consciousness of the fish with a strong fighting spirit and avoid the killing due to the fight between the fish. Furthermore, even if the salt concentration of seawater to be prepared is lowered, most of the saltwater fish can be bred, so the amount of artificial seawater components used is small and economical, and the amount of salt dripping outside the aquarium is greatly reduced, In addition, there is an advantage that saltwater fish and freshwater fish can be mixed.

According to the third aspect of the present invention,
There is an advantage that the above-mentioned excellent effect can be reliably exhibited and an inexpensive artificial seawater preparation can be provided.
