Problems solved by technology

[0003] Although a complete breeding technology system has been established for shrimp farming, most of the farming techniques are still traditional techniques, that is, open, static water breeding, relying on a large number of water changes to improve water quality and relying on drugs to prevent and control diseases, but a large number of drugs will inevitably affect Water quality, and then rely on a large number of water changes to maintain water quality. After a large amount of medication, the shrimp system will be weakened. A large number of water changes will also lead to a large amount of nutrient loss, which will easily lead to a decrease in the survival rate of shrimp. Therefore, the traditional shrimp farming process is a Vicious circle, not ecological farming

Embodiment approach 1

[0017] Whole Pond: Thoroughly remove the silt in the pond and fill in cracks and holes.

[0018] Clear pond: 10 days before the shrimp seedlings are stocked, mix an appropriate amount of shrimp and crab protective agent with 10 times the concentration of 8‰ salt water according to the size of the pond, stir and dissolve, and let it stand for 1 hour and then sprinkle it on the whole pond to kill Predators of fish, frogs, leeches and other shrimps.

[0019] Plant submerged plants: plant 4 submerged plants per square meter in the shallow water area around the pond, such as Elodea or shrimp algae, hay grass, Hydrilla verticillium, and Malayan eye vegetable, to ensure that the submerged plants cover the entire pond at 40 %; On the one hand, submerged plants can provide habitat and shelling environment for shrimps, and can also be used as natural bait for shrimps; Provides shaded habitat for shrimp when high.

Abstract

The invention relates to the field of freshwater farming of penaeus vannamei boone and discloses an ecological freshwater farming method for the penaeus vannamei boone. The method mainly comprises the steps of performing a pond, cleaning the pond, planting submerged plants, injecting water, cultivating water fleas, desalinating fry, performing fry stocking, performing reasonable feeding and alternately catching the penaeus vannamei boone out of the pond. Compared with the prior art, chemicals are basically not used in the whole farming process, water is not changed in quantity to guarantee that the farmed penaeus vannamei boone is high in survival rate, high in disease resistance and growth speed and more delicious in taste, and therefore high economic benefits can be achieved.

Description

technical field [0001] The invention relates to the freshwater culture field of Penaeus vannamei, in particular to a freshwater ecological culture method of Penaeus vannamei. Background technique [0002] Commonly known as white-legged shrimp and white-legged shrimp, it is one of the three largest shrimps in the world today. The meat is delicious, and the processed meat rate can reach as high as 67%. It has a wide temperature range and can grow at 18-32°C. It is also wide and can grow under the condition of salinity 1-40‰. It is an excellent desalination cultured species. Penaeus vannamei is active at night and prefers to be quiet and afraid of being startled. [0003] Although a complete breeding technology system has been established for shrimp farming, most of the farming techniques are still traditional techniques, that is, open, static water breeding, relying on a large number of water changes to improve water quality and relying on drugs to prevent and control disease...
