Description

Method of reserving the freshness of live fishes and the cultivation using mineral ions}

The present invention relates to a method for maintaining freshness and culture of live fish, and more particularly, moving live fish, such as wild animals and aquaculture, from a sea or cage farm to a fish farm or an aquarium, and then most of the live fish die after several days. There was a problem in the distribution and preservation of live fish, but by adding ionic minerals to the saltwater of fish farms and aquariums to keep fresh fish fresh and preserved, it is rich in fresh and beneficial minerals for people who eat live fish. The present invention relates to a method for maintaining freshness and farming of live fish using ion minerals.

In general, water contained in aquaculture tanks, such as fish farms, which farm various kinds of live fish, is easily contaminated by ammonia (NH3), nitrous acid (NO2), and food waste from various excreta generated during fish farming. Because of this, when left unattended, fish may have various diseases and cause death, as well as secondary pollution when these polluted waters are discharged to the outside of the tank.

Live fish moved from the sea, cage farms, fish farms, etc. to the public aquariums do not provide any feed for freshness, quality, and flavor, and most live fish die within a few days (2-5 days). There was this.

Therefore, there are problems such as rising prices of live fish due to distribution problems that must be supplied daily from aquaculture and fish farms for the supply of fresh live fish. There have been frequent cases of illegal drugs.

In addition, how much minerals are needed for animals or humans, why they are needed, and how important they play an important role in maintaining freshness and survival is well described in our patent application No. 10-2006-01367839, “Compound Ion Mineral Composition”. .

The present invention has been made in order to solve such problems and concerns, the object of the present invention is the essential element of fish and the most beneficial to the human body, but the most insufficient calcium (Ca), potassium (K), magnesium (Mg), zinc ( Maintain the freshness of live fish using ion minerals that can supply livestock with four minerals such as Zn) to reduce live mortality, improve distribution structure, and inexpensive, fresh and high in mineral content. It is about aquaculture method.

In order to achieve the above object, the present invention primarily uses calcium chloride, potassium chloride, magnesium chloride, and zinc chloride to prepare a chloride solution having a total content of 20-30% having a neutral pH.

This mineral solution was added to an aquarium containing seawater where oxygen was supplied for 24 hours and filtration of dirt, for each concentration of 0.0% (not added), 0.05% (2000 times), 0.1% (1000 times) and 0.2% (500 times). 80 days of 20 flounders from each West Aquarium cage were added to each aquarium to observe the mortality, and the flounders in the mineral-free aquariums were stored frozen for testing of mineral elements after death. The flounder of the addition aquarium was taken out after 30 days, frozen, and used for testing for mineral element analysis.

However, the reason for setting the time of 30 days here is a breakthrough if it survives only freshly within about 10 days in distribution and preservation, and the flounder of the added group has not lost any flounder after 30 days. Surviving flounder was more than 80% of the total.

As described above, the present invention supplies the four major minerals, such as calcium (Ca), potassium (K), magnesium (Mg), and zinc (Zn), which are essential elements of fish and are most beneficial to the human body. Thus, there is an effect of reducing the mortality of live fish, by improving the distribution structure by this effect is cheap, fresh, and has the effect of tasting live fish with a high mineral content beneficial to the human body.

Hereinafter, the present invention is to maintain the freshness of live fish, reduce mortality, improve the distribution structure and maintain the freshness and freshness of live fish using ionic minerals that can be eaten by eating cheap, fresh, high mineral content beneficial to the human body A detailed description of the method is as follows.

The concentrations of the above minerals were in terms of ppm and consisted of Ca (calcium / 29,000PPM), K (potassium / 84,000PPM), Mg (magnesium / 8,900PPM), and Zn (zinc / 600PPM). Note, 1% concentration is 10,000 PPM)

Five tons of seawater off the west coast and 100 fish of the same size from the west coast cages were transferred to a live fish tank and filled with 1 ton of saltwater in each of the four aquariums prepared in advance. After adding and dissolving uniformly, 20 flounders were added.

The test aquarium was oxygenated and filtered for 24 hours, and no feed was added.

Each aquarium was divided into A, B, C, and D and minerals were added to each aquarium as follows.

Aquarium A: 0.0% mineral stock (not added)

Aquarium B: Add 0.05% of mineral stock (2000 times) (500g to 1 ton of seawater)

Aquarium C: 0.10% (1000 times) of mineral stock solution (1,000g per ton of seawater)

Sample Preparation for Survival Results and Elemental Analysis

1. Survival Results

Aquarium A: 20 animals, including 12 animals on 3rd day, 7 on 4th day and 1 on 5th day, died 100% within 5 days.

Aquarium B: 90% survival (2 dead) after 30 days, 13 (75%) survival after 60 days,

Aquarium C: 100% survival after 30 days, 17 animals (85%) after 60 days,

Aquarium D: 100% survival after 30 days, 16 (80%) survival after 60 days,

2. Sampling for Mineral Element Analysis

In Aquarium A, one dead animal was stored as a sample on the fourth day.

And, the samples in the aquariums B, C, and D were taken and stored frozen in one tank in each tank after 30 days.

The frozen samples were commissioned by Korea Testing and Research Institute and analyzed according to the Hazardous Metals Test of Food Code 2006.

As can be seen from the above results, Mg and K did not change much compared to the body's intrinsic content of flounder, but 0.05% of Ca and about 25% and Zn also increased by 10%.

Therefore, the result is not absolute but mortality was only 10%, Mg 0.1% and 0.2% of the mineral stock solution increased by about 15% in Mg, about 8% in K, and about 30 ?? 40% in Ca. Zn increased by about 25%. As can be seen from the results, it was found that the contents of Ca and Zn, which are trace minerals, were increased much more than the increase of Mg and K, which are large minerals. Accordingly, the mortality was only 0%, and the effect was very excellent. .

Accordingly, by supplying ionic minerals with neutral pH, the survival rate in the distribution and preservation of live fish can be improved, thereby improving the distribution structure and greatly reducing the price of live fish. Furthermore, ingesting fresh live fish containing high concentration of minerals It has been found through the present invention that the beneficial benefits such as indirectly safe intake of minerals beneficial to the human body. For example, according to the results of the present invention, it can be concluded that if one adult consumes 1 kg of live fish fed with minerals, in theory (when digested at 100%), the daily recommended amount of minerals may be consumed.
