CATDOLL : CATDOLL: I want to rent a pond to raise some silver carp. How many silver carp should be raised per acre of water?

Regarding silver carp farming, the first thing that comes to mind is fertilizer farming. In fact, many waters themselves store a lot of nitrogen, phosphorus, potassium and other nutrients. Natural nitrogen, phosphorus and other nutrients in the surrounding environment usually gather repeatedly in the breeding waters through rainwater, and as long as they are properly "fertilized", they can be filled. Today, we talk about algae growth conditions and fertilizers, which can turn these nutrients into fish production. There are a lot of fish in the reservoir, and the water quality has not deteriorated, but last month, 60,000 kilograms of fish were caught in the nets. For example, in the 500-acre reservoir in Neijiang, mackerel accounted for half of them. The owner of the reservoir said that the feeling is that the reservoir has been the best since Huabai, and the reason for the increase in production is that a large number of beneficial microorganisms have been invested.

We do not blindly advocate fertilizers and fish farming, but advocate the supplementation of beneficial microbial fertilizer water, maximize the use of light energy, achieve high yields while protecting water resources, and realize economic and environmental value.

Most of the algae species on the market are actually nutrients that promote bird growth, not actual bird seeds. The most commonly mentioned bird species on the market are chlorella and dry powdered algae. If it is truly alive chlorella, it will be exposed to light during storage, and the chlorella will photosynthesize and consume nutrients. After the nutrients are used up, the shelf life will be shortened by about 1 or 2 months. This is a defect in the sales and use of chlorella, so it is best to keep low light during storage.

For new ponds such as ponds with good surrounding water quality, it is most cost-effective to collect surface water and introduce algae species in this way. Supplement the nutrients needed to promote algae growth. For example, the most economical and fast method is to equip algae fertilizers and phosphorus fertilizers, as well as appropriate amounts of nitrogen fertilizers and amino acids. On this basis, adding activators or algae promoters, carbon source peptides, lactic acid bacteria, etc. can achieve the purpose of rapid algae cultivation. If it is planted in a seedbed, mature and fermented organic matter can be supplemented with base fertilizer. If the water color becomes lighter, sugars and amino acids, EM bacteria can be added to accelerate the reproduction of algae in the water body.

When using live chlorella algae, pay attention to the shelf life. When applying, add aromatic peso to ensure the normal growth of chlorella. As for dry powder bird species, no company that makes seaweed powder has been found in China. The so-called dry powder algae species are actually nutrients and algae promoters. You will find that after putting it into the pond, the color of the water will become better, which actually promotes the growth of unicellular algae in the water body.

When it comes to birds, it's all about light. Algae grow through photosynthesis. While diatoms have a lower light requirement, the light requirements of green algae and others are much higher. That said, these algae always tend to the middle and upper layers of the water. In order to absorb more light. If the water clarity is low, a coagulant such as Detox Turbidity Clear or Black Carbon can be used to add clarity.

For silver carp culture, about 150,000 silver carp can be stocked per 100 mu of water surface. Single stocking is the main method, and mixed stocking is not recommended. Generally, the ponds should be divided after about one month of culture. The water source and water quality of the pond environment for silver carp culture should be close to lakes, reservoirs, rivers, and channels. Silver carp is a pelagic fish that feeds on plankton throughout its life. It mainly eats zooplankton in the fry stage, and gradually turns to phytoplankton when it grows to more than 1.5 cm.

Large water areas are generally more than 10000 mu, mainly for raising silver carp, the best size is more than 200g/tail, the survival rate is high, the ratio is 1:3, and about 100 to 200 fish are released per mu. Some reservoirs and lakes have thin water quality and more floating organisms, so the stocking amount of silver carp can be appropriately increased.

About 150,000 silver carp can be raised per mu of water. It is mainly based on single breeding, and it is best not to mix them. Pants add beneficial microbial fertilizers to the water, maximize the use of pure and durable light energy, achieve high yields while protecting water resources, and realize economic and environmental values.
