Description
FEED MAKING METHOD FOR FARMING FISH
Technical Field
[1] The present invention relates, in general, to a method of producing feed for farmed fish, and more particularly, to a method of producing feed for farmed fish, in which an agar solution is added to produce feed for farmed fish which is capable of floating on water in order to prevent precipitation of the feed, and in which the surface of the feed is coated with an agar solution to drastically decrease the putrefaction rate of the feed so as to safely supply raw feed, having a high nutritional value and being easily digested, and to prevent water pollution thanks to a high feed uptake rate, and also to enable maintenance of the feed in a fresh state by keeping it in cold storage, and as well, an infrared sterilizer for drying feed for fish is used to increase the hygiene of the feed. Background Art
[2] Generally, fish has been farmed in fish farms using a process of supplying raw feed and a process of supplying mixed feed.
[3] When the raw feed is supplied, fish for feed is washed and then cut to an appropriate size to supply it to fish farms. As such, since it is difficult to store such raw feed for a long period of time and to supply it every time it is required, the feed has been stored in a frozen state. Further, the raw feed, which is supplied to the fish farm, is precipitated in water, and thus it is difficult for farmed fish to eat the precipitated feed. Furthermore, when the frozen feed is supplied into water, it may easily putrefy while thawing. Thus, before the feed putrefies, it should be removed from the fish farm, which is difficult. Consequently, the uptake rate of the supplied feed is only about 50%, and the feed is wastefully used. Moreover, since water of the fish farm should be replaced to remove the feed from the fish farm before it putrefies, loss of the feed and waste of water and electric power increase.
[4] On the other hand, in the case of supplying mixed feed, the mixed feed does not putrefy, unlike the raw feed, but suffers because it is digested less completely than the raw feed, thus increasing the probability of generating fish diseases, and because it is very expensive. Disclosure of Invention
Technical Problem
[5] Accordingly, the present invention has been made keeping in mind the above problems occurring in the prior art, and an object of the present invention is to provide a method of producing feed for farmed fish, in which an agar solution is added to raw
feed, and thus the resultant feed is capable of floating on water in order to prevent the precipitation of the feed.
[6] Another object of the present invention is to provide a method of producing feed for farmed fish, in which the surface of the feed is coated with the agar solution, and thus the putrefaction rate of the feed is drastically decreased so that raw feed, which has a high nutritional value and is easily digested, can be safely supplied, and water pollution can be prevented thanks to the high feed uptake rate, and also, the feed can be maintained in a fresh state because it is possible to keep the feed in cold storage.
[7] A further object of the present invention is to provide a method of producing feed for farmed fish, using an infrared sterilizer for drying feed for fish, therefore enhancing the hygiene of the feed.
[8]
Technical Solution
[9] In order to accomplish the above objects, the present invention provides a method of producing feed for farmed fish, comprising removing floating material of fish for feed, washing the fish for feed, and then dehydrating it; finely cutting the fish; mixing the finely cut fish with an agar solution, sea weed, and yellow soil, with stirring; loading the mixture into a mold to form it into a predetermined size and shape; and dipping the feed mixture into the agar solution and drying it, thus forming a coating film on the feed to prevent dispersion of the feed in water due to the penetration of water so as to prevent environmental pollution.
[10] Preferably, the feed mixture may comprise 100 parts by weight of finely cut fish,
20-40 parts by weight of agar solution, 3-15 parts by weight of sea weed, and 2-10 parts by weight of yellow soil, and the sea weed may comprise brown seaweed and sea tangle.
[11] Also, the method may further comprise mixing the feed mixture with fish meal, oil cake, soybeans, minerals, vitamins, and vinegar.
[12] In addition, the present invention provides a method of producing feed for farmed fish, comprising removing floating material of fish for feed, washing the fish for feed, dehydrating the fish for feed, dipping the fish for feed into an agar solution, and drying it, thus forming a coating film on the fish for feed.
[13] In addition, the present invention provides feed for farmed fish, comprising a feed mixture prepared by mixing and stirring finely cut fish for feed, an agar solution, sea weed, yellow soil, and additives and then forming the mixture into a predetermined size and shape, and a coating film formed on the feed mixture by dipping the feed mixture into the agar solution and drying it.
Advantageous Effects
[14] According to the method of producing feed for farmed fish of the present invention, an agar solution is added to produce feed for farmed fish which is capable of floating on water in order to prevent precipitation of the feed.
[15] Further, the surface of the feed is coated with the agar solution, and thus the putrefaction rate of the feed is drastically decreased, so that raw feed, having a high nutritional value and being easily digested, can be safely supplied, with the prevention of water pollution thanks to the high feed uptake rate.
[16] Furthermore, since the feed is coated with the agar solution, it can be stored in a fresh state because it is possible to keep the feed in cold storage. Moreover, an infrared sterilizer for drying feed for fish is used, therefore enhancing the hygiene of the feed.
[17]
Brief Description of the Drawings
[18] The above and other objects, features and other advantages of the present invention will be more clearly understood from the following detailed description taken in conjunction with the accompanying drawings, in which:
[19] FIG. 1 is a flowchart showing a process of producing feed for farmed fish, according to a first embodiment of the present invention; and
[20] FIG. 2 is a flowchart showing a process of producing feed for farmed fish, according to a second embodiment of the present invention. Best Mode for Carrying Out the Invention
[21] Hereinafter, a detailed description will be given of a method of producing feed for farmed fish according to the present invention, with reference to the appended drawings.
[22] Referring to FIG. 1, fish for feed is finely cut, mixed with various materials, including an agar solution, and stirred, thus producing feed which can easily float on water and has a high nutritional value.
[23] To this end, fish suitable for feed is selected, and floating material thereof is removed, after which the fish is washed. Subsequently, the washed fish is dehydrated to be semi-dried and is then finely cut. Upon dehydration, when an infrared sterilizer is used, the fish is rapidly dried and sterilized at the same time, and thus it is possible to conduct a process hygienically.
[24] As such, the fish for feed preferably includes fry, that is, the young of fish. In addition, since a finely cutting process may be performed, large fish may be used.
[25] After finely cutting the fish, it is mixed with various materials, including the agar solution, and stirred. In addition to the agar solution, sea weed, yellow soil, and additives are used.
[26] The agar solution has a property of easily floating on water by virtue of its very low
specific gravity. Hence, when the agar solution is mixed and stirred, it functions to prevent the precipitation of the raw feed in water and to enable the feed to float.
[27] Thus, conventional disadvantages, such as a low feed uptake rate by farmed fish due to precipitation of raw feed, may be overcome, and the feed uptake rate can be drastically increased.
[28] Examples of the sea weed include brown seaweed and sea tangle. The sea weed including the brown seaweed and the sea tangle, which has an effect of discharging harmful heavy metals from the body, is added to the feed, in order to prevent bacterial infection of farmed fish and to help treat and mitigate fish diseases. Further, yellow soil functions to aid digestion and to effectively treat and mitigate fish diseases.
[29] Examples of the additives include fish meal, oil cake, soybeans, minerals, vitamins, and vinegar, which may be used to promote the uptake of various nutrients, thereby aiding the growth of farmed fish.
[30] In particular, the vinegar contained as the additive enables the further reduction in the size of the finely cut fish and softens the fish. Therefore, the digestion of the farmed fish taking such feed may be promoted.
[31] The feed mixture comprises 100 parts by weight of the finely cut fish, 20-40 parts by weight of the agar solution, 3-15 parts by weight of the sea weed, 2-10 parts by weight of the yellow soil, and 1-5 parts by weight of the additives.
[32] After the mixing and stirring process, the feed mixture is loaded into a mold and then formed into shapes and sizes appropriate for the eating habits of the fish. Subsequently, the feed thus formed is stored in a refrigerator or a freezer.
[33] According to the method of producing the feed of the present invention, the agar is mixed to produce the feed, such that the precipitation of the feed is prevented, thus increasing the feed uptake rate. Thereby, waste of the feed is decreased, and putrefaction of the feed and water pollution can be considerably reduced.
[34] Turning now to FIG. 2, a flowchart showing the process of producing feed for farmed fish, according to a second embodiment of the present invention, is shown. As shown in FIG. 2, the feed, which is produced according to the production method of FIG. 1, is dipped into the agar solution in order to coat the surface of the feed with the agar solution. Although the agar solution is a gel at room temperature, it changes into a liquid sol state when heated. Thus, when heat is applied to the agar solution, the agar solution is converted into sol. Subsequently, the mixed feed having a predetermined shape is dipped into the above agar sol, removed therefrom, and then dried. The agar solution adhering on the surface of the mixed feed changes into a gel state such that the surface of the mixed feed is coated. Accordingly, the penetration of water into the feed is prevented, thus preventing the dispersion of the feed in water, leading to the prevention of environmental pollution caused by the dispersion of conventional feed in
water.
[35] Further, the feed may float on water, and as well does not come into direct contact with water or air, thus inhibiting the putrefaction of the feed.
[36] Conventionally, water of fish farms is frequently replaced to prevent the occurrence of fish diseases as well as water pollution due to putrefaction of the feed. Thus, excessive water is used and the power required to operate a pump is wastefully consumed. With the goal of solving such a problem, although mixed feed has been used, it is much more expensive than the raw feed, and thus the use thereof is avoided.
[37] However, according to the method of producing the feed of the present invention, the surface of the feed is coated with the agar solution, and thus farmed fish can eat all the feed before putrefaction of the feed. In addition, since the feed does not precipitate, the extent of putrefaction and uptake of the feed may be accurately monitored by a worker, thereby drastically decreasing the use of water and power.
[38] In addition, feed may be produced using fish alone, rather than the above mixed feed including various materials. That is, fish is finely cut to an appropriate size, dipped into an agar solution, and then dried, such that the fish may be coated with a film of agar in a gel state to be suitable for use in raw feed.
[39] In this way, the feed may be produced according to the above production methods disclosed by the present inventor. Mode for the Invention
[40] A better understanding of the present invention may be obtained through the following example which is set forth to illustrate, but is not to be construed as the limit of the present invention.
[41] Floating material of 1 kg of mackerel was washed, after which the mackerel was dehydrated and then sterilized using an infrared sterilizer. Subsequently, the mackerel was finely cut using a cutter and then mixed with 300 g of an agar solution, 70 g of brown seaweed and sea tangle, 50 g of yellow soil, and 40 g of additives (fish meal, oil cake, soybeans, minerals, vitamins, and vinegar), and stirred. The mixed and stirred feed was loaded into a mold and thus formed to a predetermined size and shape. The produced feed was dipped into an agar solution and then dried, thus coating the surface of the feed (with agar).
[42] The feed thus produced did not easily putrefy compared to conventional feed, had a high uptake rate by fish, and could be kept in cold storage, and thus could be stored for a long period of time.
[43] Although the preferred embodiments of the present invention have been disclosed for illustrative purposes, those skilled in the art will appreciate that various modifications, additions and substitutions are possible, without departing from the scope
and spirit of the invention as disclosed in the accompanying claims. Industrial Applicability
[44] As described above, the present invention provides a method of producing feed for farmed fish. According to the method of producing the feed of the present invention, resultant feed can exhibit excellent properties mentioned above and thus can be more widely used than conventional feed. In addition, since the production method of the present invention can be applied to production of feed of livestock, as well as farmed fish, it can have very wide applicability.
Claims
[1] A method of producing feed for farmed fish, comprising: removing floating material of fish for feed, washing the fish for feed, and then dehydrating it; finely cutting the fish; mixing the finely cut fish with an agar solution, sea weed, and yellow soil, with stirring; loading the mixture into a mold to form it into a predetermined size and shape; and dipping the feed mixture into the agar solution and drying it, thus forming a coating film on the feed to prevent dispersion of the feed in water due to penetration of water so as to prevent environmental pollution.
[2] The method according to claim 1, wherein the feed mixture comprises 100 parts by weight of the finely cut fish, 20-40 parts by weight of the agar solution, 3-15 parts by weight of the sea weed, and 2-10 parts by weight of the yellow soil.
[3] The method according to claim 1, wherein the sea weed comprises brown seaweed and sea tangle.
[4] The method according to claim 1, further comprising mixing the feed mixture with fish meal, oil cake, soybeans, minerals, vitamins, and vinegar.
[5] A method of producing feed for farmed fish, comprising removing floating material of fish for feed, washing the fish for feed, dehydrating the fish for feed, dipping the fish for feed into an agar solution, and drying it, thus forming a coating film on the fish for feed.
[6] Feed for farmed fish, comprising a feed mixture prepared by mixing and stirring finely cut fish for feed, an agar solution, sea weed, yellow soil, and additives and then forming the mixture into a predetermined size and shape, and a coating film formed on the feed mixture by dipping the feed mixture into the agar solution and drying it.
