Problems solved by technology

[0003] A few points should be paid attention to in the cultivation of freshwater lobster: Do not raise too many bottom fish, and remove miscellaneous fish before placing lobster seedlings and during lobster breeding to prevent lobsters from being swallowed; Lobster farming will reduce the size and output of lobsters and increase the cost of farming; lobster seedlings should not be selected from natural bred lobsters in chai ponds and reed ditches, and it is not suitable to breed lobsters in fish ponds, which will affect the size and output of lobsters and waste water resources, not easy to produce economic benefits
[0004] At present, some freshwater lobster breeding methods are unscientific, resulting in freshwater lobsters containing antibiotics, hormones and other drugs, excessive heavy metals, and even parasites and pathogenic bacteria, posing a threat to people's health

Embodiment 1

[0018] Choose a pond with sufficient water source and no silt. The depth of the pond is 1m. Set up an insulation shed on the top of the pond, and set up 0.5m high anti-escape facilities around it. Set up 3 water inlets and outlets in the pond, and set up a 30-mesh filter at the inlet and outlet. Insect water, remove the natural enemies of lobsters, and expose to the sun for 3 days to get vacant ponds.

[0019] Put 0.5m deep water into the vacant pond, plant reeds after disinfection, and throw in slow-release nutrients. Among them, the coverage area of ​​aquatic plants accounts for 30% of the pond area, and the slow-release nutrients are attapulgite stick soil and hydroxyphosphorus The mixture of limestone and fermented organic fertilizer, the weight ratio is 3:2:1, place a small shelter, adjust the water temperature of the pond to 15°C, the dissolved oxygen to 6mg / L, and the pH value to 6.5 to obtain a cultivation pond.

Embodiment 2

[0022] Choose a pond with sufficient water source and no silt. The depth of the pond is 1.5m. Set up an insulation shed above the pond, and set up 0.5m high anti-escape facilities around it. Open 4 water inlets and outlets in the pond. The water of the pond worm was removed from the natural enemies of the lobster, and it was exposed to the sun for 5 days to obtain an empty pond.

[0023] Put 1m deep water into the empty pond, plant water hyacinth after disinfection, and throw in slow-release nutrients. Among them, the covered area of ​​aquatic plants accounts for 40% of the pond area, and the slow-release nutrients are attapulgite stick soil, hydroxyphosphorus The mixture of limestone and fermented organic fertilizer, the weight ratio is 3:2:1, place a small shelter, adjust the water temperature of the pond to 25°C, the dissolved oxygen to 8mg / L, and the pH value to 7.5 to obtain a cultivation pond.

Embodiment 3

[0026] Choose a pond with sufficient water source and no silt. The depth of the pond is 1.2m. Set up an insulation shed on the top of the pond, and set up 0.5m high anti-escape facilities around it. Set up 3 water inlets and outlets in the pond. The water for pond worms was removed from the natural enemies of the lobster, and it was exposed to the sun for 4 days to obtain an empty pond.

[0027] Put 0.7m deep water into the empty pond, plant Elodea after disinfection, and throw in slow-release nutrients. Among them, the covered area of ​​aquatic plants accounts for 35% of the pond area, and the slow-release nutrients are attapulgite stick soil, The mixture of hydroxyapatite and fermented organic fertilizer, the weight ratio is 3:2:1, place a small shelter, adjust the water temperature of the pond to 20°C, the dissolved oxygen to 7mg / L, and the pH value to 7 to obtain a cultivation pond.

Abstract

The invention discloses a pollution-free fresh water lobster breeding method which includes the steps that a pool is prepared, a greenhouse, an anti-theft facility and a water inlet / outlet pipe with a filtering screen piece are configured, water is injected after sunshine, water plants are planted after disinfection, slow-release nutrient substance and small shelters are put into the pool, the water temperature, dissolved oxygen and PH value of the pool are adjusted, then young lobsters are put into the pool, feeding is conducted according to different periods of the young lobsters, the water quality is improved at a fixed period, young grass carp and screws are put into the pool, and pollution-free fresh water lobsters are obtained. By means of the pollution-free fresh water lobster breeding method, an excellent growth environment is provided for the lobsters through algae, the slow-release nutrient substance and the small shelters, microorganism reagents and vitamin complex are put into the pool at a fixed period, the lobsters are fed according to different growth periods, quick growth of the lobsters is promoted on the basis of guaranteeing healthy and pollution-free lobsters, and the yield of the lobsters is increased.

Description

Technical field: [0001] The invention belongs to the technical field of lobster cultivation, and in particular relates to a method for cultivating pollution-free freshwater lobsters. Background technique: [0002] Freshwater lobster, commonly known as crayfish, belongs to the lobster family Arthropoda phylum Decapodidae. It has a thick head and chest, a hard shell, and delicious meat. It is a nutritional and nourishing food with low fat, low cholesterol, and high protein. Freshwater lobster not only has a large body and plump meat, but also has the characteristics of short growth cycle, high yield, and strong adaptability to miscellaneous food, which is especially suitable for artificial commercial farming. [0003] A few points should be paid attention to in the cultivation of freshwater lobster: Do not raise too many bottom fish, and remove miscellaneous fish before placing lobster seedlings and during lobster breeding to prevent lobsters from being swallowed; Lobster far...
