At present, the spring shrimp in Rudong area has entered the stage of shrimp production. Shrimp farming should not only be able to raise, but also be able to sell. At present, the common problems are more soft-skinned shrimps, poor body color and low survival rate during long-distance transportation. As a result, the shrimp that farmers have worked so hard to raise is underpriced and cannot be sold at a good price, resulting in economic losses. So, in the later stages, what needs to be paid attention?

[Voice of the First Line] A shrimp agent told me that they were rushing to pull the shrimps raised in this way.

1. pay attention to top dressing and maintain fertility

Some breeding friends think that there is no need to supplement fertilizer in the later period. In fact, the later the more careless. Moderate fertility can provide sufficient oxygen for the water body, and the abundance of algae can bring the stability of various indicators of the water body, and at the same time can absorb a large number of harmful substances. In addition, the losses caused by the late inverted algae are often very huge. Therefore, in the later stage of breeding, recommendDiatom WangTop dressing. Diatom Wang is rich in algae growth nutrients and small peptides, excellent water solubility, with a significant role in rapid water fertilizer.

2. prevention of bottom heat and hypoxia

Later, the weather was hot and the temperature in the shed was higher. The later stage of the flushing caused a large amount of organic matter in the bottom of the enrichment, organic matter oxidation decomposition consumes a large amount of oxygen at the bottom, so that it is easy to cause the bottom of the "oxygen debt", "bottom heat" phenomenon, shrimp feeding slow, no feeding, bait waste, sub-salt high situation. recommend useThe bottom is changed to white and black., can quickly act on the bottom of the pool, on the one hand, absorb all kinds of nutrient-consuming substances, on the other hand, can quickly and continuously release oxygen, effectively reducing the occurrence of "swimming pond" caused by hypoxia.

Supplement of 3. calcium

With the increase of the size of shrimp in the later period, the demand for calcium in the process of shelling and hard shell also increases, and the growth of algae in water also needs a large amount of calcium. In addition, the most important thing is that the hardness of the shrimp shell is directly related to the price and yield per mu. The same specifications of shrimp, hard shell prices and production will be higher. Therefore, the late calcium problem should not be underestimated. RecommendHigh calcium hard shell treasure, feed additive grade calcium element, after scientific compounding, calcium and phosphorus double supplement, into the water immediately, after use to achieve rapid hard shell, component has, naturally high yield.

4. improve body color

The body color of shrimp is often neglected by farming friends. The quality of the body color when selling shrimp is also one of the indicators selected by the intermediary. The body color of shrimp with high yield and good selling price tends to be cyan. Shrimp body color is determined by the type of pigment cells under the epidermis, different pigment cells contain different pigment particles, such as blue, black, yellow, red and so on. Shrimp with higher astaxanthin, the darker the body color, the redder the body color after cooking, the more popular with consumers. Astaxanthin, on the other hand, cannot be produced by itself and must be ingested by the outside world. Therefore recommendNatural AstaxanthinIts rich astaxanthin comes from nature, which is more easily absorbed by prawns and has a more obvious effect. At the same time, astaxanthin itself is recognized as the fourth generation antioxidant, and its antioxidant capacity is 550 times that of vitamin E. Later add astaxanthin shrimp, anti-stress ability is stronger, long-distance transport survival rate is naturally high.
