본 발명은 새우 치어의 양식방법에 관한 것으로, 더욱 상세하게는 새우 치어의 양식기간을 단축시키고 생존률을 향상시키는 효과를 나타내는 새우 치어의 양식방법에 관한 것이다.
The present invention relates to a method of breeding shrimp, and more particularly, to a method of breeding shrimp that shortens the breeding period and improves the survival rate of the shrimp.
새우는 갑각류에 속하는 동물로서, 크기에 따라 대하, 중하, 젓새우 등으로 분류된다. 대하나 중하는 단백질이 풍부하고 고소한 맛이 나기 때문에 식재료로써 인기가 높다. 그런데, 이러한 대하나 중하는 수요에 비해 공급이 크게 부족한 실정이며, 시장에서 거래되는 새우는 대부분 양식에 의해 조달되고 있다.Shrimp are crustaceans belonging to crustaceans, depending on the size of the shrimp are classified as large, small and small. It is very popular as a food ingredient because it has a rich and sweet taste. However, there is a considerable shortage in supply compared to the demand for these types of shrimp, and shrimp traded on the market are mostly procured by farming.
통상적으로, 새우 양식장은 해안지역에서 땅을 파거나 폐 염전을 양식장으로 전환하여 3,000평 내지 20,000평의 규모로 크게 형성된다. 새우 양식장은 제방 또는 통행용 둑에 의해 경계가 구분되는 장방형으로 되어 있으며, 내부에 해수가 채워진다. 통행용 둑의 적어도 어느 한 곳에는 해수를 유입하기 위한 수로가 갑문을 통해 연결될 수 있다.Traditionally, shrimp farms are largely formed on a scale of 3,000 to 20,000 pyeong by digging the land in the coastal area or converting the lung tidal field into a farm. Shrimp farms have a rectangular shape that is bounded by a bank or a traffic dam, and the inside of the shrimp is filled with seawater. At least one of the navigational dikes can be connected to the waterway through a gate to introduce seawater.
그리고 양식장 내부에는 용존산소 조절 목적으로 다수의 수차가 설치되며, 이와 같은 양식장에서는 인공부화장에서 부화된 새우 치어(치하)가 봄철에 입식되어, 수온에 따라 대략 100일에서 180일의 기간 동안 생육된 후 가을에 출하되는데, 종래에 양식장에서는 입식되는 치어의 생존률이 40~50%를 나타내어 손실률이 지나치게 높고, 새우 치어야 양식기간이 길어 생산성이 저하되는 문제점이 있었다.A number of aquariums are installed in the farm for the purpose of controlling dissolved oxygen. In these farms, the shrimp hatchlings incubated in artificial hatcheries are stocked in spring and grown for about 100 to 180 days depending on the water temperature However, in the past, the survival rate of the stocked poultry was 40 to 50% in the poultry farm, so that the loss rate was too high and the poultry farming period was long.
또한, 종래에 새우 양식장에는 지속적으로 새우 배설물, 사료 찌꺼기, 탈피된 껍질, 새우 사체 등 오염물질이 축적되는데, 일반 어류를 양식하는 소형 양식장의 경우 펌프에 의해 물 교환이 수시로 이루어지는 것과 달리, 새우 양식장은 넓이가 넓고 수량이 많아 물 교환을 하는 것이 사실상 불가능하며 자연증발에 따른 감소량을 보충하는 수준에 그치고 있다. 이에 따라, 새우 양식장에서는 축적되는 오염물질을 계외로 배출할 수 있는 마땅한 방안이 없으며, 양식장 수질은 시간이 경과함에 따라 크게 악화되는 문제점이 있었다. 또한, 기존 새우 양식의 경우 치어의 치사율이 거의 절반에 달하며, 각종 바이러스 및 병균에 의해 성체의 품질 및 크기가 자연산 새우에 비해 미달하는 경우가 많고, 출하시까지 양식 기간이 길어 생산성이 떨어지는 단점이 있다.
In addition, contaminants such as shrimp excrement, feed residue, peeled shell, and shrimp carcass are accumulated in shrimp farms conventionally. In case of a small farm where general fish farming is carried out, water is frequently exchanged by a pump, It is virtually impossible to exchange water because of its large area and large quantity, and it is only at the level of compensating for the decrease due to natural evaporation. As a result, there is no proper way to discharge the accumulated pollutants from the shrimp farm, and the quality of the shrimp is deteriorated over time. In addition, in case of existing shrimp farming, the rate of frying is almost half, and the quality and size of adult is less than that of wild shrimp due to various viruses and germs, and the productivity is low due to long cultivation period have.
본 발명의 목적은 새우 치어의 양식기간을 단축시키고 생존률을 향상시키는 새우 치어의 양식방법을 제공하는 것이다.It is an object of the present invention to provide a method of breeding shrimp that shortens the culture period of shrimp and improves the survival rate.

The method for culturing shrimp according to the present invention is characterized in that the method comprises the steps of (a) preparing a shrimp water producing step (S101) of injecting seawater into a water tank for shrimp cultivation equipped with a shading net, and (b) A first microorganism propagation step (S103) for propagating microorganisms by adding a microorganism growth agent, a first feed feeding step (S103) for feeding a shrimp feed to the cultured microorganisms through the first microorganism propagation step (S103) (S105), a shrimp frying step (S107) in which the shrimp fry is introduced into the aqua mixed with the feed water through the first feed feeding step (S105), the shrimp fry feeding step (S107) A second microorganism propagation step (S109) for propagating the microorganism by injecting a microorganism growth agent into the microorganism propagation step (S109), and a second feed introduction step for introducing the shrimp feed to the microorganism- (S111) , And the second microorganism propagation step (S109) and the second feed step (S111) are repeated a plurality of times, preferably six to seven times, at intervals of one week after the second feed feeding step (S111) .
상기 양식수제조단계(S101)는 해수를 차광망이 설치된 새우 치어 양식용 수조에 투입하고 산소를 주입하는 단계로, 일반 새우 양식장과는 분리되되, 일정한 크게로 양식된 새우 치어가 양식장으로 이동할 수 있는 배출구가 구비되며, 해수가 직사광선으로부터 차단될 수 있도록 차광망이 설치된 양식용 수조에 해수를 채운 후에 산소를 주입하여 새우 약식용 양식수를 제조하는 단계다. 이때, 새우 치어 양식용 수조는 차광망이 설치된 하우스 같은 공간에서 지표면 기준 상부인 지상에 설치될 수도 있으며, 지표면 기준 하부인 지하에 설치될 수도 있다.In step S101, the seawater is poured into a water tank for shrimp cultivation equipped with a light-shielding net, and oxygen is injected. The shrimp can be separated from a general shrimp farm, It is a stage to prepare seawater in the aquaculture tank equipped with the light-shielding net so that the seawater can be cut off from the direct sunlight, and then to inject the oxygen to produce the shrimp edible aquaculture water. At this time, the water tank for shrimp farming can be installed on the ground above the ground surface in the house-like space where the light-shielding net is installed, or may be installed in the ground below the ground surface.
상기 양식수제조단계(S101)는 15 내지 30일 동안 이루어지는 것이 바람직한데, 상기와 같이 15 내지 30일 동안 해수에 산소를 주입하게 되면, 해수에 미생물이 증식되어 양식수로 적한한 조건을 갖추게 된다.The water production step S101 is preferably performed for 15 to 30 days. When the oxygen is injected into the seawater for 15 to 30 days as described above, the microorganism is proliferated in the seawater and the condition is satisfied .
상기와 같이 수조에 차광망을 설치하는 이유는 양식수에 직사광선이 도달하게 되면, 수온상승으로 인해 용존산소량이 급격하게 즐어들고, 조류와 유해균이 증식되어 새우 치어의 폐사율이 향상될 수 있기 때문이다.The reason for installing the light shielding net in the water tank as described above is that when the direct sunlight reaches the aquaculture water, the dissolved oxygen amount rapidly increases due to the rise in the water temperature, and algae and harmful bacteria are proliferated and the mortality rate of the shrimp can be improved.
이때, 수조에 주입되는 산소는 새우 치어가 목표하고자 하는 크기로 양식될 때까지 지속적으로 이루어지는 것이 바람직하며, 산소의 주입이 지속적으로 이루어지면, 상기 제2사료투입단계(S111) 이후에도 양식수의 수질이 일정하게 유지될 수 있다.
At this time, it is preferable that oxygen injected into the water tank is continuously performed until the shrimp is cultured to a desired size. If oxygen is continuously injected, water quality of the aquaculture water after the second feeding step (S111) Can be kept constant.
상기 제1미생물증식단계(S103)는 상기 양식수제조단계(S101)를 통해 제조된 양식수에 미생물증식제를 투입하여 미생물을 증식시키는 단계로, 상기 양식수제조단계(S101)를 통해 제조된 양식수 100m3당 미생물 증식제 0.5 내지 1.5kg을 투입하고 5 내지 10일 동안 미생물이 증식되도록 하는 단계인데, 상기와 같이 미생물 증식제가 투입되면, 상기 양식수제조단계(S101)를 통해 해수에 증식되었던 미생물의 개체수가 급격하게 증가하게 된다.The first microorganism propagation step (S103) is a step of propagating microorganisms by injecting a microorganism growth agent into the aquaculture water produced through the aquaculture water production step (S101). The microorganism propagating step (S103) 0.5 to 1.5 kg of the microbial growth agent per 100 m 3 of the aquaculture water is added and the microbes are allowed to proliferate for 5 to 10 days. When the microbial growth agent is introduced as described above, the step (S 101) The number of microorganisms that have become microorganisms is rapidly increased.
이때, 상기 미생물 증식제는 스테비아와 강황이 9:1의 중량부로 혼합되어 이루어지는 것을 사용하는 것이 바람직한데, 상기와 같이 스테비아와 강황이 9:1의 중량부로 혼합되어 이루어진 미생물 증식제가 함유되면, 상기 미생물 증식제를 먹이로 하여 새우 치어의 먹이로 적합한 미생물인 유익균의 증식 우점화가 이루어진다. 스테비아는 미생물 유익균 번식에 좋은 먹이가 되며, 강황은 치어에 각종 바이러스 및 병균으로부터 내성 및 면역력을 높여주는 기능을 하여 스테비아가 90% 이고, 강황이 10%일 때 미생물 성장면과 새우 면역력 제공면에서 가장 바람직하게 새우 치어 성장에 최적화된 미생물 양식수가 제조될 수 있다.At this time, it is preferable that the microorganism growth agent is a mixture of stevia and turmeric in a weight ratio of 9: 1. When the microorganism growth agent is mixed with stevia and turmeric in a weight ratio of 9: 1 as described above, The proliferation of the beneficial microorganism, which is suitable for the feeding of the shrimp, is fed to the microbial growth agent. Stevia is a good food for microbial breeding, and turmeric enhances tolerance and immunity from various viruses and germs in fry, so that 90% of stevia and 10% of turmeric are responsible for microbial growth and shrimp immunity Most preferably, microbial cell counts optimized for shrimp growth can be produced.
또한, 상기 미생물 증식제는 상기와 같은 유익균의 증식 우점화를 유도하여, 각종 잡균의 증식으로 인해 새우 치어가 폐사하는 것을 억제하는 역할도 한다.In addition, the microbial growth agent induces the propagation of the proliferation of the beneficial bacteria as described above, and also plays a role of inhibiting the death of the shrimp due to the proliferation of various germs.
상기 미생물 증식제의 함량이 0.5kg 미만이면 상기의 효과가 미미하며, 상기 미생물 증식제의 함량이 1.5kg을 초과하게 되면 상기의 효과는 크게 향상되지 않으면서 새우 치어의 양식비용을 증가시키게 된다.
If the content of the microbial growth agent is less than 0.5 kg, the above-mentioned effect is insignificant. If the content of the microbial growth agent exceeds 1.5 kg, the effect is not greatly improved but the cultivation cost of the shrimp is increased.
상기 제1사료투입단계(S105)는 상기 제1미생물증식단계(S103)를 통해 미생물이 증식된 양식수에 새우 치어용 사료를 투입하는 단계로, 상기 제1미생물증식단계(S103)를 통해 미생물이 증식된 양식수 100 중량부에 새우 치어용 사료 1 내지 2 중량부를 투입하여 이루어지는데, 상기와 같이 새우 치어용 사료가 함유되면, 상기 제1미생물증식단계(S103)를 통해 증식된 미생물과 새우 치어용 사료가 새우 치어의 먹이로 공급되며, 상기의 미생물과 사료를 먹이로 하게 되면 새우 치어의 성장속도가 빨라지기 때문에, 새우의 양식기간이 줄어들게 된다.The first feeding step (S105) is a step of feeding the shrimp feed to the aquaculture water in which the microorganisms have been propagated through the first microorganism propagation step (S103). In the first microbial propagation step (S103) And 1 to 2 parts by weight of feed for shrimp are added to 100 parts by weight of the proliferated aquaculture. When the shrimp feed is contained as described above, the microorganism propagated through the first microorganism propagation step (S103) Feeding of prawns is fed to shrimp fry. Feeding the above microorganisms and feeds will speed up the growth of shrimp fry, thus reducing the cultivation period of shrimp.

The shrimp feed consisting of the above ingredients is rich in nutritional ingredients to help the growth of the shrimp, allowing the shrimp to grow rapidly, To improve the immunity of the shrimp to reduce the mortality of the role is also.
상기 새우 치어용 사료의 함량이 1 중량부 미만이면 상기의 효과가 미미하며, 상기 새우 치어용 사료의 함량이 2 중량부를 초과하게 되면 상기의 효과는 크게 향상되지 않으면서 양식수가 오염도가 증가하여 새우 치어의 폐사율이 증가할 수 있다.
If the content of the shrimp feed ingredients is less than 1 part by weight, the above effect is insignificant. If the content of the shrimp feed ingredients exceeds 2 parts by weight, the effect is not significantly improved, The mortality of the fry may increase.
상기 새우치어투입단계(S107)는 상기 제1사료투입단계(S105)를 통해 사료가 혼합된 양식수에 새우 치어를 투입하는 단계로, 상기 제1사료투입단계(S105)를 통해 새우 치어용 사료가 혼합된 양식수 100 중량부에 새우 치어 3 내지 10 중량부를 투입하는 단계다.The step S107 of injecting the shrimp is a step of injecting the shrimp into the aqua-mixed water through the first feeding step S105, and the shrimp feed for the shrimp is fed through the first feeding step (S105) And 3 to 10 parts by weight of shrimp are added to 100 parts by weight of mixed water.
이때, 상기 새우 치어는 대하 치어 또는 흰다리새우 치어가 바람직하며, 1 내지 2밀리미터 길이의 치어를 사용하는 것이 더욱 바람직하다.At this time, the shrimp is preferably a shrimp or white-legged shrimp, more preferably 1 to 2 millimeters long.
상기 새우 치어의 투입량은 특별히 한정되지 않고 양식수의 수질유지 조건에 따라 결정되는데, 양식비용과 양식수의 수질유지에 적합하도록 3 내지 10 중량부를 투입하는 것이 바람직하다.The amount of the shrimp to be poured is not particularly limited and is determined according to the conditions for maintaining the quality of the aquaculture water. It is preferable to add 3 to 10 parts by weight of the shrimp so as to be suitable for maintaining the quality of the aquaculture water and the aquaculture water.
상기 새우 치어의 투입량이 3 중량부 미만이면 양식비용 대비 소득이 부족하게 되며, 상기 새우 치어의 투입량이 10 중량부를 초과하게 되면 양식수의 수질유지가 곤란하게 된다.If the amount of the shrimp is less than 3 parts by weight, the income of the shrimp is insufficient. If the amount of the shrimp is more than 10 parts by weight, it becomes difficult to maintain the quality of the aquaculture.
상기의 새우치어투입단계(S107)를 통해 새우 치어가 투입되면, 새우 치어가 미생물 및 사료를 먹이로 하여 성장하며, 새우 치어의 배설물은 양식수에 잔존하는 미생물에 의해 분해되어 양식수의 오염이 억제된다.
When the shrimp fry is introduced through the shrimp frying step (S107), the shrimp fry grows as food for microbes and feeds, and the excrement of shrimp fry is decomposed by microorganisms remaining in the aquaculture water, .
상기 제2미생물증식단계(S109)는 상기 새우치어투입단계(S107)를 통해 새우 치어가 투입된 양식수에 미생물증식제를 투입하여 미생물을 증식시키는 단계로, 새우 치어가 먹이로 잡아먹는 미생물의 개체수가 유지될 수 있도록 새우 치어가 투입된 양식수 100m3당 미생물 증식제 0.5 내지 1.5kg을 투입하여 이루어진다.In the second microorganism propagation step (S109), the microorganism propagating agent is added to the aquaculture water into which the shrimp is introduced through the shrimp frying step (S107), and the microorganism is propagated by the microorganism propagation step.

It is a condition for rapid growth.
이때, 외부의 조건변화나 온도상승으로 인해 양식수의 용존산소량이 상기의 범위를 벗어나는 경우 상기 수조에 주입되는 산소의 양을 조절하여 상기 범위의 용존산소량을 나타낼 수 있도록 하는 것이 바람직하며, 양식수의 pH가 7.5 내지 8.0의 범위를 벗어나는 경우에는 양식수에 탄산칼슘을 투입하여 양식수의 pH가 상기의 범위를 유지할 수 있도록 하는 것이 바람직하다.In this case, when the dissolved oxygen amount of the aquaculture water is out of the above range due to external condition change or temperature rise, it is preferable to adjust the amount of oxygen to be injected into the water tank so as to be able to show the dissolved oxygen amount in the above range. The pH of the culture water can be kept within the above range by adding calcium carbonate to the aquaculture water.
상기와 같이 제2미생물증식단계(S109)와 상기 제2사료투입단계(S111)가 일주일 간격으로 6 내지 7회 반복되면 새우 치어가 2 내지 10센티미터로 성장하게 되는데, 상기의 크기로 성장한 새우는 새우 치어 양식용 수조에 구비된 배출구를 통해 도4에 도시된 일반 양식장으로 이동한 후에 20 내지 25 센티미터로 양식하여 상품화한다.As described above, when the second microorganism propagation step (S109) and the second feed feeding step (S111) are repeated six to seven times at a week interval, the shrimp grows to 2 to 10 centimeters.
