Description

[Background Art] [0002] Fishery farming system Preventing From Red Tide Damaging [

The present invention relates to a red tide damage prevention aquaculture system, and more particularly, to a red tide damage prevention aquarium system that operates to prevent the supply of seawater when a red tide occurs and to maintain aquaculture environment of aquaculture water.

The method of onshore aquaculture is a technology that is widely used and widely used by fishermen because it is convenient to supply appropriate water temperature according to abundant water source and fish species. However, in the above-mentioned on-shore aquaculture method, since the sea water is directly taken from the sea and adjusted to a suitable temperature for the culture and supplied to the tank, the problem of water quality and temperature control of the supply water becomes the most important problem. Changes in water supply temperature due to rapid changes in seawater temperature also cause the production rate to drop or the growth rate to deteriorate. For example, in the case of flounder culture, the optimum growth temperature is 17 ° C to 19 ° C. Therefore, even when the temperature of the feed water reaches 21 ° C, anomalies occur in the seedling culture in the water tank and the growth rate of the fry is about 50% lower than that of the optimum growth temperature. In addition, inadequate water temperature can cause the fish to lose their ability to defend the fish. In addition, according to the research report, it has been shown that there is a difference in the food intake of the fry depending on the change of the water temperature, so that it affects the growth rate. For example, it has been reported that the flounder that grows optimally at 17 ° C slows down at low temperatures (about 14 ° C) and does not eat about half of the feed at 15 ° C at high temperatures (above 20 ° C).

In this way, the water temperature in the water tank in the aquarium forms a significant influence on the growth of the fish. Accordingly, in the winter when the present temperature is lower than the proper temperature, the seawater is heated by the boiler and supplied to the water tank. In summer, the water is heat-exchanged with the relatively low temperature groundwater by adjusting the water temperature to the proper temperature. Is being used.

FIG. 1 is a schematic view of a conventional water supply system for an aquaculture farm. As shown schematically in FIG. 1, the system includes a pump 10 for introducing seawater from the sea, A heat exchanger 20 for first preheating or precooling the feed water by exchanging heat with the wastewater discharged from the culture water tank T while passing filtered water through the filter 11, A heat pump 30 for heating / cooling the feed water to a temperature suitable for the culture by exchanging heat with the coolant while passing the preheated / precooled feed water passing through the heater 20 and the heat pump 30, (T) for storing the wastewater discharged from the aquaculture tank (T), filtering the wastewater discharged from the aquarium (T), passing the heat exchanger (20) and the heat pump (30) W).

In the coastal waters of Korea, red tide phenomenon has occurred since May every year, causing serious damage to the aquaculture industry. In the case of red tide, there has been a problem that the aquaculture fish are killed by the seawater flowing into the aquaculture tank. There is a need for development of an aquaculture system.

It is also possible that the seawater discharged through the discharge pipe 241 is supplied to the aqua regulating tank 210. The dissolved oxygen amount of the seawater is measured in the dissolved oxygen amount measuring sensor 243 from the seawater flowing through the discharge pipe 241.
