Description

Technical Field

[0001] The invention relates to the technical field of freshwater marine aquaculture, and in particular to a new inland freshwater marine aquaculture model. Background Art

[0002] The key to marine aquaculture is to maintain good water quality. Water quality indicators such as pH, ammonia nitrogen content, nitrite, etc. need to be tested regularly to ensure that they are within a safe range. Use filters and other water purification equipment to reduce suspended matter and harmful substances, adjust the temperature of the aquarium according to the habits of different species, and ensure that sufficient light is provided to support the growth of corals and other marine life. From the existing technology, common marine aquaculture can only be carried out near the sea, and freshwater oceans cannot be carried out inland. The few freshwater oceans simply set up a filtration system. After long-term use, the water quality is easy to deteriorate and it is not easy to carry out aquaculture. For this reason, we propose a new model of inland freshwater marine aquaculture. Summary of the invention

[0003] In view of the shortcomings of the prior art, the present invention provides a new inland freshwater marine aquaculture model, which has the advantages of land freshwater ocean and long-term stable water quality.

The water pipes are equipped with water pumps. The fish pond uses the water pipes to introduce water into the purification pool and the ecological pool respectively. The purified water in the purification pool is introduced into the ecological pool through the water pipes. The output end of the ecological pool is connected to the thermostat through the water pipe, and the thermostat re-introduces the water into the fish pond through the water pipe; Step 3: Prepare seawater in the seawater regulating pool, which is directly connected to the ecological pool through a water pipe; Step 4: Lay filter material in the ecological pool and add filter screen in the purification pool; Step 5: Test the water quality in the seawater transfer tank, purification tank, ecological tank and fish pond after one week of circulation; Step 6: After the water quality test is normal, add the aquaculture in batches; Step 7: Maintain equipment and record the growth of plants.

[0005] Preferably, the preparation of seawater in step 3 comprises the following steps: S1: Prepare artificial sea salt and fresh water. Use pure water that has been exposed to the sun. S2: Calculate the appropriate ratio of artificial sea salt to fresh water, and record the weight of sea salt and the volume of fresh water; S3: Pour the weighed sea salt into the fresh water and stir thoroughly until the salt is completely dissolved; S4: Use an accurate buoyancy hydrometer or optical hydrometer to measure the salinity of seawater to ensure that it is close to natural seawater; S5: Control seawater temperature to meet the needs of marine life; S6: Keep the prepared artificial seawater static for 12 hours and then test it again.

[0006] Preferably, in step one, the number of purification pools is half of the number of fish ponds.

[0007] Preferably, in step one, the purification tank comprises a dry-wet separation tank and a purification tank, the dry-wet separation tank uses a metal screen to separate seawater particles, and the separated seawater flows into the remaining purification tank.

[0008] Preferably, in step 4, the number of ecological ponds is three quarters of that of fish ponds, and the ecological ponds include brush ponds, multi-level ecological ponds and clear water ponds.

[0011] Preferably, in step S3, the sea salt is added to the fresh water and the stirring time is 0.5-2h.

[0012] Preferably, in step S5, the temperature of the seawater is adjusted to 20-25°C.

[0013] Preferably, in step one, the seawater regulating pool, purification pool, ecological pool and fish pond are all paved with anti-corrosion materials, and the overall frame is made of 316 grade stainless steel. Beneficial Effects

[0014] 1. In the present invention, by setting up a seawater regulating pool, a purification pool, an ecological pool and a fish pond, the purpose of cultivating seawater products inland is achieved. The seawater regulating pool is established to facilitate the allocation of seawater. The purification pool includes a dry-wet separation pool. The filter net inside the dry-wet separation pool is used to filter the particulate matter inside the fish pond to reduce the toxic substances in the seawater.

[0015] 2. In the present invention, a brush pool is set up in the ecological pool. The brush pool is convenient for intercepting the total microorganisms in the seawater pool, and the gaps between the brushes effectively cultivate nitrifying bacteria, which is convenient for eliminating ammonia nitrogen substances in seawater, improving water quality, and stabilizing the water body. The filter material in the ecological pool provides a place for nitrifying bacteria, and seawater plants are cultivated in the ecological pool, so that the prepared seawater is closer to natural seawater.

[0043] Compared with Examples 1, 2, and 3, in Examples 1 to 3, seawater in the same fish pond was selected for detection, and algae were cultured in three types of seawater. The state of the algae was observed to roughly determine the water quality problem. The growth of algae can reflect the health of the water quality, thereby indirectly evaluating the water quality of the sea tank. The state of the algae is shown in Table 1. The concentration of organic matter is detected in the three types of seawater, and the content of organic matter is indirectly understood by testing the concentration of inorganic phosphorus (PO4), because there are many types of organic matter in natural seawater, and inorganic phosphorus is one of them. The comparison of the concentration of inorganic phosphorus (PO4) is shown in Table 2. Finally, the three types of seawater are tested with test paper. The test paper test uses a seven-in-one water quality test paper to easily detect key water quality indicators such as pH value, hardness, and nitrate concentration. The three experiments all use a one-month cycle. The experimental results show that in the breeding process, purification pools and ecological pools are indispensable.
