As the failure rate of conventional shrimp farming has gradually increased in recent years, the share of shrimp farming in winter and spring has also been increasing. Even many farmers have abandoned the normal summer season and only raise winter and spring. . Due to the external environment of low temperature, shrimps in winter and spring are mostly concentrated in factories in Shandong and southern sheds, but it is also the reduction of farmers and their time to market that led to higher prices than others. Due to the relatively low temperature in winter and spring, it has also increased the difficulty of farming. North and south farmers will build insulation sheds and boilers, but some problems are still handled improperly. 1. Due to the low temperature, algae are difficult to reproduce and extremely unstable. Many farmers have the phenomenon of submerged algae after the replacement of water. Algae not only play a role in insulation but also reduce the stress of shrimp. 2. The prawn's physique is weak and growth is slow. Many prawn's oyster shells are small and slow, feeding is difficult and susceptible to disease. 3. Hypoxia can easily cause hypoxic stress in shrimp. The most important thing for shrimp aquaculture is stability. Both environmental and management needs to be stable. Under hypoxic conditions, the growth of shrimp or the success rate of clam shells will be affected because low dissolved oxygen is the cause of most shrimp diseases. The necessary conditions are that many harmful anaerobic microorganisms cannot fully reproduce if the dissolved oxygen is sufficient, while shrimp can grow normally. 4. The ventilation in the pond is also more critical. Ventilation can increase the amount of dissolved oxygen on the surface of the pond water, reduce the pressure in the shed, maintain the stability of the temperature in the shed, and increase the propagation speed of the algae. 5. Breeding density, lack of algae decomposition ability, poor oxygen production capacity, and instability of hydration index, especially sub-salt can easily increase. Shrimp need to be carefully maintained in winter and spring, and high yields need to bear high risks. 1. The use of algal peptide + algal fertilizer + cream experts, specifically for low temperature difficult fertilizer and rich in algae species, long-lasting fertilizer. 2. Regularly splashing and feeding Jinwei'an + ionized calcium / liver Shukang / CB vitality, etc., to improve the prawn's constitution, reduce the occurrence of stress, shorten the shell phase. 3. The winter aquaculture is best installed at the bottom of the oxygen tube, the use of aerator, the first oxygen, the outside air must be drawn into the aerator before, reduce the concentration of carbon dioxide in the water. 4. Regularly exchanging water, use detoxifying stress serum + Weidi + stealing Kangkang to prevent toxins from rising. All the above links are the most important concerns for shrimp breeding in winter and spring. Reasonable and regular use of drugs, early detection, and early treatment can eliminate most of the disease problems and provide escort for winter and spring shrimp farming, and increase the success rate of breeding.
