If the water is five meters deep, there will be many kinds of fish, shrimp, crabs, frogs and so on. The key is whether you have mastered the technology of aquaculture, which is actually quite simple. Now is the best time to breed aquatic products. If you plan to raise it, buy the strain liquid of fry and cultured bacteria and make preparations in advance.

(A) the role and mechanism

EM ecological probiotic stock solution can inhibit pathogenic microorganisms and harmful microorganisms, adjust the ecological environment of aquaculture, increase dissolved oxygen in water, promote the activation and growth of normal flora and beneficial algae in aquaculture ecosystem, and maintain the ecological balance of aquaculture. Feeding with bait can directly enhance the absorption function, disease prevention ability and anti-stress ability of fish, and promote healthy growth. Photosynthetic bacteria in EM ecological probiotic stock solution can also utilize hydrogen sulfide, organic acids and nitrogen in water, and also have denitrification effect to eliminate ammonium nitrite in water, thus purifying excreta and residual bait in aquaculture ponds, improving water quality and greatly reducing fish and shrimp diseases. Microecological agents with antagonistic properties are applied to aquaculture water or added to feed to kill or inhibit pathogenic microorganisms and provide a good living environment for cultured animals. It can prevent the accumulation of toxic substances amine and ammonia and protect the body from poisoning.

1, stimulate the immune system and improve immunity. Eliminate pollutants and purify the environment.

2. Increase the number of beneficial microorganisms. There are many zooplankton and beneficial algae on the water surface, especially red worms, which cover the water surface continuously.

3. Stabilize and improve water quality. The water body is bright in color, tasteless, non-corrosive, and has no odor such as hydrogen sulfide and ammonia. The visibility is long and stable at 25- 1250px, and the water change time can be extended by more than 2 times.

4. Fish and shrimp manure, impurities at the bottom of the pond and leftovers will not turn into silt and present loose sand.

5, promote growth, and the weight gain rate is obviously improved. Practice has proved that in the same environment, after using the original solution of EM ecological probiotics, it can be put on the market in advance, the average yield per mu is increased by 20%-35%, the spawning amount is increased and the spawning time is prolonged. Good hatching rate; The bait is tasteless, which improves the culture environment.

(2) Method of use

1, pond treatment

Before the pond is filled with water 1 week, the pond is disinfected and purified with 100-300 times of Yi Fuyuan EM ecological probiotic stock solution and an insect repellent made of EM ecological probiotic stock solution instead of lime and bleaching powder. 0.5- 1 kg per square meter. The preparation method of the insect-proof liquid: the probiotic stock solution, vinegar, Chinese liquor (above 30℃) and water are mixed according to the ratio of1:1:1:1:. The EM ecological probiotic stock solution and water are made into diluent, sealed in plastic containers (glass bottles are not allowed), and fermented for 2-3 days at ambient temperature above 25 degrees. After the gas is inflated, the lid is opened and deflated, vinegar and white wine are added, stirred evenly and sealed, and then fermented for more than two weeks. Gas will be produced during fermentation. When the container expands, the lid will loosen the air and then seal it until no gas is generated. You can smell the sweet and sour vinegar, which means that the fermentation has been completed and you can use it. Keep it closed in a cool place, usually for 6 months.

2. Purification of water

3- 10 days before stocking, the water surface was sprinkled with Yi Fuyuan EM ecological probiotic stock solution. Depending on the water quality, 15 days 1 time, 1 month 1 time. Where the water quality is poor, the watering time should be shortened appropriately; The proportion can be one millionth of the total water, or 2-4 kilograms per mu of water surface (depending on the depth of the pool water). In order to spray evenly, the original solution of EM ecological probiotics should be diluted before use.

3. Feed treatment

The feed can be fermented with Yi Fuyuan EM ecological probiotic stock solution, and the fermented feed is evenly mixed into fish feed according to the proportion of 5-7% for feeding. You can also use 300 times EM diluted solution of ecological probiotics to mix in the feed before feeding. Fermentation material production: weighing feed raw material 150kg, EM ecological probiotic stock solution 1kg and water 35-45%. Production method: EM ecological bacteria are prepared and fermented into liquid diluent of EM bacteria, then added into the required water and stirred evenly, and then added into the feed raw materials evenly, so that the water content of the solid feed reaches 35-45%, which can be dispersed at the touch of hands. Firstly, aerobic fermentation is adopted, and after the feed temperature reaches 40-50 degrees, it is put into a plastic container for closed fermentation, and the ambient temperature is above 25 degrees Celsius, 65438. Sealed for 6 months.

4. Pellet feed

According to the total amount of pellet feed of 1: 200 em, the original ecological probiotic solution was sprayed evenly and fed immediately.

5, organic fertilizer and manure treatment

Organic fertilizer (grass liquid fertilizer) and manure to be put into water should be treated with EM ecological probiotic stock solution first, and then put into water after fermentation. For the fermentation method, see (3) Production of fermentation materials.

6. Prevention and treatment of fish diseases

In case of fish flooding, 2-3 kg/mu of EM ecological probiotic stock solution can be evenly sprinkled on the water surface, and the fish can get better and return to normal in 3-5 hours. After that, it can be poured again every 1-2 days. Individual fungal fish diseases, bacterial enteritis, gill rot, printing diseases, etc. Can be taken out and directly smeared with EM ecological probiotic stock solution 10-50 times.
