1. What is integrated shrimp pond farming? What is the significance of integrated farming? What are the main integrated farming methods?

1. Integrated shrimp pond farming is a diversified, three-dimensional farming method, including multi-crop farming, multi-species rotation farming, and multi-species mixed farming. This farming model can make use of the biological and ecological characteristics of fish, shrimp, crab, shellfish, and algae, such as their different habitats, feeding habits, etc., to scientifically adjust the structure of farming species and the farming cycle, so as to make full use of the potential of water bodies and baits, learn from each other's strengths and weaknesses, and promote the virtuous cycle of substances and energy in water bodies, build a scientific mechanism for ecological disease prevention, better play the productivity of water bodies, and improve the ecological and economic benefits of shrimp ponds.

2. Especially in the current situation where shrimp diseases are rampant, it is more practical to carry out comprehensive breeding according to local conditions. Among the comprehensive breeding of shrimp ponds, polyculture is the most representative.

3. The main ones include polyculture of shrimp and fish, polyculture of shrimp and shellfish, polyculture of shrimp and crab, polyculture of shrimp and sea cucumber, polyculture of shrimp and algae, and even polyculture of shrimp, fish and crab.

2. What are the breeding models for Penaeus vannamei in saline-alkali land?

There are two main modes of breeding white shrimp in saline-alkali land: ecological polyculture and intensive breeding. The ecological polyculture mode is mainly suitable for large areas of water, or large ponds (kiln pits) that cannot be converted into small areas. It mainly feeds on plankton in natural waters and fish leftovers, and is mixed with crabs, fish, clams and other species. The intensive breeding mode is suitable for breeding ponds with complete supporting facilities and standardized breeding management.

The intensive culture of white shrimp depends on the saline-alkali water quality. Generally, the stocking density of shrimp seedlings is 25,000 to 40,000 per mu, and the culture output is 200 to 300 kg per mu. In terms of the species, the polyculture mode of white shrimp can be mixed with pike, tilapia, crabs, clams and some freshwater fish. The polyculture mode helps to reduce the spread of shrimp diseases; fish feed on different water layers and different types of natural bait organisms, which helps to maintain the ecology of the breeding pond and improve the overall economic benefits of the pond. In terms of the breeding mode, you can breed shrimp as the main species and mix other fish, or you can breed shrimp as the main species.

The mixed farming form is a model based on the cultivation of whiteleg shrimp. The stocking density of shrimp should not exceed 40,000 per mu. A small amount of freshwater silver pomfret, pike and tilapia and other fish can be stocked. The stocking capacity of large-sized fish seedlings is preferably 20 to 30 per mu. If silver carp and bighead carp are stocked, the stocking capacity of seedlings can be appropriately increased, and it is preferably not more than 50 per mu.

For example, if the polyculture model is mainly based on the cultivation of freshwater fish such as tilapia, the stocking density of shrimp should be 3,000 to 5,000 per mu. However, when polyculture, attention should be paid to the stocking specifications, quantity and stocking time of different types of fish. It is recommended to stock fish when the shrimp fry grows to more than 4 cm.

3. Is shrimp farming risky?

1. Investment is risky. There are many risks in investing in shrimp farms, such as being easily affected by unfavorable weather such as external cooling and rainfall. Once improperly managed, shrimps will have a high incidence rate, low yield, and poor sales channels. 2. For shrimp farms, because the factory-based circulating water aquaculture model maintains a constant temperature and is not affected by unfavorable weather such as external cooling and rainfall, shrimps grow faster, have a lower incidence rate, and have a higher breeding density in this breeding environment, which effectively increases the yield of shrimps. Whether in terms of hardware equipment such as pond facilities and aerobic conditions, or in terms of breeding concepts and medication habits, we still follow the breeding routines of the four major carps. These old routines have buried hidden dangers and risks in freshwater shrimp farming and have long been abandoned by coastal shrimp farmers.
