The correct application of shrimp stocking operation method is an important part of raising the survival rate of green shrimp and raising the yield of shrimp culture. Here are some views on how to properly apply the shrimp farming practices.

First, it must be done after raising oxygen

In the autumn, when the shrimps are stocked, they are in the high temperature season. The seedlings and seedlings generally end in the early morning to early morning. However, at this time, it is the time when the water in the pond is most deprived of oxygen. If no oxygenation measures are taken in advance, the shrimp ponds should not be used. Will inevitably lead to shrimp seedlings are not strong, "set foot seedlings" and more, which is extremely wrong, for this purpose, requiring the seedlings to pull seedlings before the water must be oxygenation, specific methods: First, flushing more than 2 hours, the second is Casting a quick-improving oxygen booster, an aerator for aerators, and a quicker tank than shrimp, until most of the shrimp in the cage can “fight water” before they can develop seedlings. Conditional response to shrimp seedlings in advance to pull the net to practice seedlings.

Second, we must increase the oxygen transport of living water, and strive to reduce the phenomenon of low survival rate of shrimp due to improper transport methods.

In the survey, we found that most farmers used dry baskets, basins, foot buckets, manure buckets, sieves, and Other tools for dry transport. There were many seedlings inside, and the stacking pressure was severe. Then they were transported by hand, motorcycles, tractors or even tricycles. When a farmer in Nangang Township was transporting seedlings in spring, the shrimps were spread on the bow and transported to Tangtou, causing all the shrimps to die. This was wrong. The majority of farmers should transport water by means of a live water boat or a vessel equipped with water and set a seedling box for aeration. Even if the shrimps of neighboring ponds are transported with a washbasin or the like, the containers should be smooth and the shrimps should not be placed too thick.

Third, must be done before the first oxygen increase seedlings

Under normal circumstances, ponds with monoculture of penaeid shrimp incubate about a week in advance to produce fertilizer and water. There are more plankton and algae in well-watered ponds. These ponds often don’t have enough oxygen in the water during the morning hours. Oxygen should also be added in time to allow the shrimp seedlings to enter a good water environment during operation and transportation frightened, which is conducive to rapid recovery of constitution. If river crabs or other species have been cultivated in the original pond, oxygenation should be added in time. The method of aerating oxygen is mainly flushing water, opening an aerator, or applying aeration oxygen.

In addition to the above three methods must be done, but also pay attention to the following matters: 1 buy seedlings should choose sunny weather, avoid fog, hot days. 2 To purchase seedlings, one must pick the "head-up seedlings" in cages, and resolutely do not take "settle seedlings", and the specifications should be large and well-proportioned. 3 When the seedlings are released, people need to stand in the water and do not stand on the shore and fall down to prevent shrimps from being planted in the mud. 4 should pay attention to the water temperature difference should not be too large. 5 Want to fertilize underwater ponds and avoid clearing (white) water.

Drum type pre cleaner is the main and primary machine in high capacity grain cleaning industry. Drum type pre cleaner is used to remove big, small impurity from grain seeds. At the meantime, drum type pre cleaner removes the light impurity by connecting air dust cleaning system. Base on the different cleaning aim, drum pre cleaner can be single drum sieve or double drum sieves. So the big straw, long branches, sands, smashed seeds, dust, etc all can be removed by drum type pre cleaner. Precleaner is fit for all type grain seed cleaning, as maize, soya bean, wheat, oat, etc. Its cleaning capacity ranges from 20-200 ton per hour. Base on different raw material, different capacity requirement, we will suggest suitable sieves.

Drum type pre cleaner is driven by gear motor and adopts chain transmission. This construction ensures its stable working performance. There is a sieve brush equipped and brush the rotation sieves. This effectively prevents grain seed clogging in sieve holes. Drum pre cleaner has a full-closed cover. This avoids dust leakage during operation and protects working environment. On top of the pre cleaner, there is an opening to connect the air suction system. At bottom of drum type pre cleaner are the impurity and clean outlets. So drum pre cleaner is always placed on a platform or a higher frame to collect the finished grain.

With good cleaning effect and user friendly feature, pre cleaning machine is widely used in heavy duty Grain Cleaning Plant, as grain supply center, big farm, seeds company.
