Abstract
현행의 재래식 물차에 의한 활어 수송방법은 활어의 수용량이 15~20%(하절기에는 수온이 높기 때문에 수송밀도가 낮고, 동절기에는 수온이 낮기 때문에 수송밀도가 높음)이므로 수송경비가 많이 드는 단점이 있다.The current method of transporting live fish by conventional water trucks has a drawback in that the live fish capacity is 15-20% (the transport density is low because the water temperature is high in summer, and the transport density is high because the water temperature is low in winter). .
활어를 저온대량으로 수송하기 위해서 활어 수송차에 냉각장치를 장착하는 방법이 연구 및 실용화가 시도되고 있으나, 냉동기의 모타를 구동시키기 위한 보조엔진의 장착뿐만 아니라 수송중에 흔들림에 견디는 전용 냉각장치의 개발등의 기술적인 문제는 물론이고 과다한 설치비등의 문제로 아직 실용화 단계에 이르지 못하고 있다. 본 발명 방법은 활어 수송차의 활어창내의 해수를 저온으로 낮추는 방법으로 활어창에 해수, 얼음, 소금을 넣어서 저온으로 냉각시킨 다음에 활어를 수납한다. 활어의 수납방법은 현행의 활어수송차의 활어창에 2단의 칸을 만들어서 각 칸마다 대량 수납되도록 한다. 그리고, 활어창의 온도를 활어의 일반 수송수온 보다 5~15℃ 낮은 상태를 유지하여(계절에 따라서 해수온도가 다름), 활어를 저온의 활어창내에 넣거나, 수송후 활어창에서 상온수(常溫水)로 옮길 때의 감온 및 승온시에 활어의 쇼크사를 방지한다.In order to transport live fish at low temperatures, research and practical use of a cooling device in a live fish transport vehicle have been attempted. However, not only an auxiliary engine for driving the motor of the refrigerator but also a development of a dedicated cooling system that withstands shaking during transportation Of course, due to the problems of the technical problems and excessive installation costs, it has not reached the stage of practical use. The method of the present invention is a method of lowering the seawater in the live fish window of the live fish transport vehicle to a low temperature to store the live fish after cooling to low temperature by adding sea water, ice and salt to the live fish window. The storage method of live fish is to make two stages in the live fish window of the current live fish transporter so that each compartment can be stored in large quantities. The temperature of the live fish window is maintained at a temperature of 5 to 15 ° C. lower than the general transport water temperature of the live fish (sea water temperature varies depending on the season), and the live fish is put in a low temperature live fish window, or at room temperature after the transport. To prevent shock of live fish at the time of temperature reduction and temperature rise.
본 발명 방법은 활어 수송차에 냉각장치를 장착하지 않고 활어를 대량 수송이 가능하므로, 냉각장치 설치비 및 수송 경비의 대폭적인 절감효과가 있기 때문에 양식 업자 및 유통업자의 경쟁력 향상에 크게 기여 할 것이다.Since the present invention is capable of mass transportation of live fish without installing a cooling device on a live fish transport vehicle, it will greatly contribute to improving the competitiveness of aquaculture farmers and distributors because there is a significant reduction in the installation cost and transportation cost of the cooling system.
Description
본 발명은 주로 횟감용으로 공급되는 각종 활어(活魚)를 수송함에 있어서, 냉각된 해수에 활어를 고밀도로 수송하는 방법을 채용하여 최대의 운송 효율을 높일 수 있도록 한 것이다.The present invention is to improve the maximum transport efficiency by adopting a method for transporting live fish in a high density in the cooled sea water in transporting various live fish mainly for the sashimi.
생활수준의 향상 및 양식 기술의 발달로, 최근 활어의 소비량이 급격히 증가하고 있으며, 앞으로도 그 소비량은 더욱 증가할 것으로 예상된다. 그런데 활어를 생산지에서 소비지까지 운송함에 있어서는 주로 재래식 활어수송차를 이용하는 방법을 채택하고 있는 실정인 바, 재래식 활어 수송방법은 수송차의 활어조 내에 물과 활어를 내입하고 봄베(산소공급기)에서 연속적으로 산소를 공급하면서 수송하고 있다.With the improvement of living standards and the development of farming techniques, the consumption of live fish is increasing rapidly, and the consumption is expected to increase further in the future. However, in transporting live fish from the place of production to the place of consumption, the conventional live fish transporting vehicle adopts a method of adopting a conventional live fish transport method, in which water and live fish are introduced into a live fish tank of a transport vehicle and oxygen is continuously supplied from a bomb (oxygen feeder). We are transporting while supplying.
그러나 이러한 재래식 방법에 있어서는 활어의 수송량이 전체량(물+활어)의 15~20%(어종이나 계절에 따라서 약간의 차이가 있으나, 하절기에는 수온이 높기 때문에 수송밀도가 낮고 동절기는 수온이 낮기 때문에 수송밀도가 높다) 정도에 불과하며, 나머지(80~85%)는 물이므로 수송경비가 증가하게 되고, 이러한 수송경비의 과다는 결국 활어 생산자나 소비자의 경제적 부담을 가중시키는 요인이 된다.However, in the conventional method, the transport volume of live fish is 15 ~ 20% of the total amount (water + live fish), but there are some differences depending on the species and season.However, because the water temperature is high in summer, the transportation density is low and the water temperature is low in winter. The transport density is high), and the rest (80-85%) is water, which increases transportation costs, and the excess of these costs adds to the economic burden on live fish producers and consumers.
특히, 하절기에는 수온의 상승을 막기 위하여 얼음주머니를 수송차의 활어조에 넣어서 수송 중에 해수의 온도상승을 막기도 하나, 이러한 방법은 0℃인 얼음이 활어에 직접 닿게 되므로 저온의 스트레스에 의한 치사율이 증가하며 바람직한 수송방법이라 할 수 없다.In particular, in summer, ice packs are put in live tanks to prevent rises in water temperature, which prevents the rise of seawater temperature during transportation.However, this method increases the mortality rate due to low-temperature stress because ice at 0 ° C comes in direct contact with live fish. It is not a preferred transportation method.
본 발명은 이러한 종래의 비효율적인 수송방법을 개선하여, 활어 수송효율을 월등히 향상시킬 수 있게 한 것으로, 이하 본 발명의 방법을 상술하면 다음과 같다.The present invention is to improve the conventional inefficient transportation method, it is possible to significantly improve the live fish transport efficiency, the following detailed description of the method of the present invention.
어류는 변온동물로서 환경온도를 낮추어 가면 호흡량 및 운동량이 점차 감소하게 되므로 고밀도로 수송이 가능하다. 활어를 저온 고밀도로 수송하기 위한 방법으로 수송차의 활어조 내의 물을 냉각하고 수송 중에 저온을 유지하기 위하여 수송차에 냉각장치를 장착하는 방법이 연구 및 시도되고 있으나, 수송차에 냉각장치의 장착을 위해서는 냉동기의 모터를 구동시키기 위한 보조엔진의 장착뿐만 아니라, 수송 중에 유동성(흔들림)에 견디는 전용 냉각장치의 개발 등 기술적인 문제점이 따르고 과다한 설치비 등의 문제로 아직 실용화 단계에 이르지 못하고 있다.Fish is a transgenic animal that can be transported at a high density because the respiration and exercise volume gradually decreases when the environment temperature is lowered. As a method for transporting live fish at low temperature and high density, researches and attempts to install a cooling device in a transport vehicle to cool water in a live fish tank of a transport vehicle and to maintain a low temperature during transportation have been conducted. In addition to the installation of an auxiliary engine for driving a motor, technical problems, such as the development of a dedicated cooling system that withstands fluidity (shake) during transportation, are accompanied by technical problems, such as excessive installation costs have not yet reached the practical stage.
본 발명은 수송차에 냉각장치를 장착하지 않고, 냉각된 해수를 수송차의 활어조에 넣거나, 활어조에 해수, 얼음, 소금을 넣어서 해수를 저온의 수송온도로 냉각시킨 후에 활어를 내입하고 수송하는 방법으로써, 본 발명은 활어조의 해수온도를 활어의 일반수송 수온보다 5~15℃ 낮은 상태로 유지하여 운송함에 특징이 있다. 이러한 저온수송은 고밀도의 수송이 가능할 뿐만 아니라 장시간의 수송기간 중에도 폐사율이 거의 없이 대량의 활어를 수송할 수 있다.The present invention is a method of inserting and transporting live fish after cooling the seawater to a low temperature transport temperature by putting the cooled seawater into the live fish tank of the transport vehicle, or by putting the seawater, ice and salt into the live fish tank, The present invention is characterized in that the seawater temperature of the live fish tank is maintained at 5 ~ 15 ℃ lower than the general transport water temperature of the live fish. Such low temperature transportation is not only capable of high density transportation but also can transport large quantities of live fish with little mortality even during long transportation periods.
이하 본 발명의 수송방법에 대하여 기술한다.Hereinafter, the transportation method of the present invention will be described.
[1. 수송차 활어조 내의 해수온도 강하방법][One. Method of lowering seawater temperature in live fish tank]
현행의 활어 수송물차의 활어조에 처음부터 냉각된 해수를 넣거나, 수송차의 활어조에 해수, 얼음, 소금을 같이 투입하고 해수를 냉각시킨다. 이때 활어조 내의 해수온도는 활어의 일반수송 수온보다 5~15℃ 낮게 설정한다(어종 및 계절에 따라서 다소간의 차이가 있을 수 있다).In the live fish tank of the current live fish tanker, the seawater cooled from the beginning is added, or the seawater, ice, and salt are put together in the tank of the truck, and the sea water is cooled. At this time, the seawater temperature in the live fish tank is set to 5 ~ 15 ℃ lower than the normal transport water temperature of live fish (may vary slightly depending on fish species and season).
참고로 해수와 얼음의 희석비율에 따른 온도강하도와 소금첨가량의 바람직한 실시예를 나타내면 다음과 같다.For reference, a preferred embodiment of the temperature drop and salt addition amount according to the dilution ratio of sea water and ice is as follows.
[2. 활어의 수납방법][2. How to store live fish]
활어의 수송방법은 활어조 내에 활어를 고밀도로 수송하기 때문에, 현행의 방법으로 수납하면 활어조 저면(底面)에 위치하는 활어는 압사 또는 스트레스를 많이 받아서 치사율이 높다.Since live fish are transported at high density in live fish tanks, live fish located at the bottom of live fish tanks are subject to high pressure or stress and have a high mortality rate.
본 발명에서는 현행의 활어 수송물차의 활어조 내에 상하 2단으로 단을 만들어서, 각 칸마다 상하 독립적으로 활어를 고밀도로 수납하여 수송한다.In the present invention, the stage is made of two stages up and down in the live fish tank of the current live fish transport vehicle, and the live fish is stored at high density independently of each space and transported.
이때 상하 활어조에는 수량(水量) 대비 100% 정도의 활어를 내장하여 운송할 수 있다.At this time, the up and down live fish tank can be transported by embedding about 100% of the live fish.
[3. 활어의 수납방법][3. How to store live fish]
현행의 활어 수송물차의 활어조 내에 상하 2단의 칸을 만들고, 냉각된 해수를 넣거나 얼음으로 해수를 냉각한 후에 활어를 수납하여 수송한다. 이 방법은 현행의 활어 수송물차의 수온보다 5~15℃ 낮게 수온을 결정하여 수송함으로써, 활어에 영향을 주지 않고 대량 수납 및 수송이 가능하다.In the live fish tank of the current live fish transport vehicle, two spaces above and below are made, and the seawater is cooled or iced, and the live fish is stored and transported. This method determines and transports the water temperature 5 to 15 ° C. lower than the current temperature of the live fish transport vehicle, thereby enabling mass storage and transportation without affecting the live fish.
[4. 수송 중에 활어조 내의 수온 유지방법][4. How to maintain water temperature in live fish tanks during transportation]
장시간의 수송 중에 활어조 내의 수온상승을 막기 위해서는 축냉재팩(縮冷材 pack)을 사용하여 온도상승을 막을 필요가 있으나, 국내에서의 활어 수송시간은 대체로 7~8시간 정도이면 전국 전지역을 커버하기에 충분하고 또한 수송 도중 외부에서 침입하는 열에 의한 수온상승은 크게 높지 않으므로(실험결과 최대로 약 2℃ 정도 상승), 단기간 수송시에는 축냉재팩의 사용을 고려하지 않아도 된다.In order to prevent the temperature rise in the live fish tank during long time transportation, it is necessary to use the cold pack to prevent the temperature rise, but the live fish transportation time in Korea is about 7-8 hours to cover the whole region. In addition, since the temperature rise due to heat invading from the outside during transportation is not very high (up to about 2 ° C as a result of the experiment), it is not necessary to consider the use of a cold storage pack for short-term transportation.
이하, 본 발명자가 소속하고 있는 부경대학교 수산과학대학 식품공학과에서 실험한 냉각해수를 사용한 활어의 고밀도 수송방법에 관한 연구 실시예를 기술하면 다음과 같다.Hereinafter, a research example of a high density transport method of live fish using cooling seawater, which was tested in the Department of Food Science and Technology, College of Fisheries Science, Pukyong National University, to which the present inventor belongs, is as follows.
[(1) 저장 온도의 영향][(1) Influence of Storage Temperature]
어류는 주위 환경의 온도가 낮아지면 호흡량 및 운동량이 감소하지만 어느 한계온도 이하가 되면 저온쇼크(shock)로 인하여 치사(致死)하게 되므로, 치사하지 않고 장기간 견딜 수 있는 한계온도의 결정을 위하여, 고급 횟감으로 소비가 많은 넙치를 시료로 하여 공기 주입을 하면서 치사시간을 관찰하였다. 그 결과, 0℃에서의 생존시간은 9시간, 3℃에서는 36시간, 7℃에서는 122시간, 15℃에서는 160시간이었으나, 5℃에서는 다른 온도보다 길어서 205시간(약 8.5일) 후에 치사하였다.When the temperature of the surrounding environment decreases, the respiratory volume and the amount of exercise decrease, but when the temperature falls below a certain limit temperature, it is dead due to low temperature shock. Lethal time was observed while injecting the flounder with high consumption as a sample. As a result, the survival time at 0 ° C. was 9 hours, 36 hours at 3 ° C., 122 hours at 7 ° C., and 160 hours at 15 ° C., but was killed at 205 hours (about 8.5 days) at 5 ° C., longer than other temperatures.
이때에 5℃보다 저온에서는 저온쇼크에 의한 치사로 판단되며, 5℃보다 고온에서는 장기간 저장에 의한 해수 중에 유해물질의 생성(암모니아 및 아질산염) 및 pH 감소에 의한 결과로 판단된다.At this time, it is judged to be fatal due to low temperature shock at a temperature lower than 5 ° C, and to a result of generation of harmful substances (ammonia and nitrite) and pH reduction in seawater by long-term storage at a temperature higher than 5 ° C.
[(2) 온도차에 의한 영향][(2) Influence by temperature difference]
활어를 저온 수송시에 서식온도와 수송온도차가 너무 크면 저온 및 고온 쇼크를 받게되므로 어종 및 온도차에 따른 쇼크 정도를 관찰하여 표 1에 나타내었다.When live fish are transported at low temperatures, if the difference between the incubation temperature and the transport temperature is too high, they receive low temperature and high temperature shocks.
상기 표 2에서 보면, 온도차 10℃에서는 전 어종 모두 큰 변화가 없지만, 온도차 15℃에서 오징어는 저온 및 고온 쇼크를 많이 받으면 치사하는 경우가 발생하였다. 넙치 및 우럭도 약간의 쇼크는 받는 것으로 판단된다.In Table 2, the temperature difference of 10 ℃ all the species do not have a big change, but when the temperature difference 15 ℃ receives a lot of low temperature and high temperature shock occurred a case of death. The flounder and Uruk are also believed to receive some shock.
상기 실험으로부터 얻어진 결과는 활어를 저온고밀도 수송시 수송온도가 활어의 일반 수송온도보다 5~15℃ 정도(어종 및 계절에 따라 차이가 있음)낮은 것이 가장 바람직하였다.The results obtained from the above experiments were most preferred that the transport temperature of the live fish at low temperature and high density is about 5 ~ 15 ℃ lower (varies depending on fish species and season) than the normal transport temperature of live fish.
(3) 저온(10℃), 고밀도(50%) 수용과 회복시의 혈액성분의 변화(3) Changes in blood composition at low temperature (10 ℃) and high density (50%) acceptance and recovery
저온(10℃), 고밀도(50%) 저장시에 활어는 스트레스를 받으며, 스트레스 정도가 크면 치사하게 된다. 저장 중에 혈액성분의 변화량을 살펴보면 다음과 같다.Under low temperature (10 ℃) and high density (50%) storage, live fish are stressed. The changes in blood components during storage are as follows.
상기 표를 살펴보면 Glucose, LDH 및 GPT값이 저장기간이 길어질수록 그 값이 증가하였으며, 저장 중에 스트레스를 받는 것으로 판단된다. 그러나, 18시간 저장 후에 상온(20℃), 저밀도(5%)의 해수에 넣고 회복을 시켰을 때 수분 후(數分後)에 유영(遊泳)하였으며, 18시간 동안 받은 스트레스로 인한 혈액성분의 변화도 약 4시간 후에는 거의 정상상태로 회복되었으며, 치사하는 경우는 거의 발생하지 않았다.Looking at the table, the value of Glucose, LDH and GPT increased as the storage period increased, and it is judged that the stress during storage. However, after 18 hours of storage, they were placed in seawater at room temperature (20 ℃) and low density (5%), and then recovered after a few minutes of swimming. After about 4 hours, the condition was almost normal, and death was rarely occurred.
(4) 저온 고밀도 수용 및 회복시의 근육성분의 변화(4) Changes in muscle composition at low temperature and high density
저온(10℃) 고밀도(50%) 저장시에 받은 스트레스에 의하여 혈액성분 뿐만 아니라 근육성분도 변화하였다.In addition to blood components, muscle composition was changed by stress received at low temperature (10 ℃) and high density (50%) storage.
상기 표 4에 나타낸 바와 같이, 젖산(Lactate)의 생성량이 증가하고 핵산 관련물질 전체량에 대한 ATP값의 비율(활력도)도 감소하여 스트레스를 받고 있음을 나타내었으며, 약 4시간의 회복시간 후에는 거의 정상상태로 회복하였고 치사하는 활어는 없었다.As shown in Table 4, the production amount of lactic acid (Lactate) is increased and the ratio (activity) of the ATP value to the total amount of nucleic acid-related substances is also reduced, indicating that the subject is stressed, and after about 4 hours of recovery time. Was almost normal and there were no dead fish.
(5) 어종에 따른 현재 수송방법 및 본 발명에 의한 수송온도 그리고 수송율의 비교(5) Comparison of current transport method according to fish species, transport temperature and transport rate according to the present invention
현행의 수송물차에 의한 수송방법은 어종 및 계절에 따라서 악간의 차이는 있지만 대체로 활어의 수송율이 15~20%인데 비교하여, 본 발명의 수송방법에서는 수송온도를 낮추고 활어조 내에 2단으로 칸을 만들어서 수납함으로써 수송율을 3~4배까지 높일 수 있었다.The current transportation method is different between the species according to the fish species and season, but in general, the transportation rate of the live fish is 15-20%, in the transportation method of the present invention, the transport temperature is lowered and the two stages in the live fish tank By making and storing, the transportation rate could be increased by three to four times.
참고로 종래의 수송방법과 본 발명의 수송방법에 따른 수송률을 비교하면 다음과 같다.For reference, the transportation rate according to the conventional transport method and the transport method of the present invention is as follows.
이상과 같이 본 발명은 종래 활어수송차에 보조엔진의 추가장착, 전용냉각장치 개발기술 및 설치비용 등으로 냉각장치의 장착이 어렵기 때문에 실용화되지 못하고 있는 활어의 저온고밀도 수송방법을, 본 발명에서는 활어조에 해수, 얼음, 소금을 넣어서 해수를 냉각시킨 후에 활어를 고밀도로 수송함으로써 수송설치비 뿐만 아니라 수송경비의 대폭적인 절약이 가능한 장점이 있다.As described above, the present invention provides a low-temperature, high-density transport method for live fish that has not been put to practical use because it is difficult to install a cooling device due to the additional installation of an auxiliary engine, the development of a dedicated cooling device, and the installation cost. After seawater, ice and salt is added to the seawater to cool the seawater, the live fish is transported at a high density, so that there is a significant saving in transportation costs as well as transportation installation costs.
그리고, 수송 전에 활어를 냉각된 활어조에 넣거나 수송 후에 저온의 활어조에서 상온수(常溫水)로 옮길 때, 고온 및 저온쇼크를 받지 않도록 온도를 5~15℃ 정도로 설정하면, 활어가 치사하지 않을 뿐만 아니라 수송 후 2~4시간이 지나면 활어는 원래의 상태로 회복된다.When the live fish is placed in a cooled live fish tank before transportation or when the fresh fish is transported from a low temperature live fish tank to normal temperature water, if the temperature is set at 5 to 15 ° C. so as not to be subjected to high temperature and low temperature shock, the live fish will not be killed. Two to four hours after transportation, the live fish returns to its original condition.
따라서, 본 발명의 방법에 의한 활어 수송방법은 종래의 수송방법에 비교하여 고밀도수송이 가능하므로 활어 수송능률을 종래보다 3~4배 정도 높일 수 있을 뿐만 아니라, 현행의 활어 수송차의 활어조를 상하 2단의 적층구조로 구성하면 수송량의 증대효과를 가져올 수 있으며, 이로 인해 수송경비의 절감효과를 가져와 양식업자 및 유통업자의 경쟁력 향상에 크게 기여할 수 있는 산업적 효과가 따른다.Accordingly, the live fish transportation method according to the present invention can increase the live fish transportation efficiency by 3 to 4 times as compared to the conventional transport method, and also raises and lowers the live fish tank of the current live fish transport vehicle. Composed of a multi-layered structure can increase the amount of transportation, resulting in a reduction in transportation costs, and has an industrial effect that can greatly contribute to the competitiveness of aquaculture farmers and distributors.
