Pond breeding method for crayfish procambrarus clarkii

Abstract

The invention relates to a method for cultivating the Krause's crayfish in pool, which comprises that preparing the pool, cultivating parental crayfish, cultivating the parent crayfish by itself and cultivating the seed. The pool preparation comprises that 1, cleaning the pool; 2, embedding organic fertilizer into the bottom and stacking the fertilizer at the slope; 3, filling water; 4, planting grass; 5, arranging tubular hidden material. And the cultivation of parental crayfish comprises that 1, disinfecting the parental crayfish; 2, cultivating the parental crayfish; 3, strengthening the cultivation. The self-cultivation of parental crayfish comprises that crossing, laying eggs, and cultivating the seed. The seed cultivation comprises that 1, spraying biological organic fertilizer into the water; 2, putting artificial feed; 3, cultivating the mature parental crayfish; 4, taking off. The invention can cultivate benthic organism to feed the parental crayfish, seed or the like, to improve efficiency and reduce pollution.

Description

technical field

[0001] The invention relates to a method for cultivating freshwater economical shrimps. Background technique

[0002] Procambarus clarkii is native to North America and is commonly known as freshwater crayfish. It belongs to Arthropoda, Crustacea, Crustacea, Decapod, Cricketidae in classification. It was introduced to my country in 1929 and has been widely distributed in my country. Due to the rapid growth of the market consumption and export processing quantity of Procambarus clarkii, the number of its wild resources is decreasing sharply. Therefore, increasing the production of Procambarus clarkii through artificial breeding has become an important way to meet the needs of processing, export and consumption markets. one of the important ways. At present, the pond culture method of Procambarus clarkii usually includes the preparation of the pond before stocking, stocking of broodstock, self-propagation of broodstock and larvae to grow into four major steps....

Embodiment 1

[0015] A method for cultivating Procambarus clarkii in ponds is as follows: before breeding broodstock, the ponds are exposed to the sun for 1 to 2 months, and are leveled, repaired and sterilized with 75 to 100 kg of quicklime. After clearing the pond, bury poultry and livestock manure into the bottom of the pond to a depth of 5 to 30 cm, and use 50 to 1,000 kg / mu of fertilizer. Gradually flow into the pool, the amount of fertilizer is 50-200 kg per mu. After the fertilization is completed, water can be injected, the water injection volume is 10-30 cm, and aquatic plants such as Elodea and water peanuts are planted at the bottom of the pond. The coverage rate of aquatic plants is not less than 20% of the total area of ​​the pond. It is a pollution-free plastic tube with an open end. The middle part of the plastic tube is divided into left and right sections by a partition. Such a plastic tube can form two independent shrimp nests to reduce investment costs. The amount of pla...

[0017] A pond culture method of Procambarus clarkii is as follows: before stocking the broodstock, the pond is exposed to the sun for 1 to 2 months, soaked with 15 to 30 kg / mu of tea dregs and soaked in water, and then sprinkled in the whole pond to kill the remaining viruses and Trash fish. After the clear pond is completed, the pig manure is buried at the bottom of the pond at a depth of 5 to 30 centimeters, and the amount of fertilizer per mu is 50 to 1,000 kilograms. After the fertilization is completed, water can be injected, the amount of water injection is 10-30 cm, and aquatic plants are planted at the bottom of the pond. The coverage rate of aquatic plants is not less than 20% of the total area of ​​the pond. Simultaneously throw in single-section bamboo tubes with openings at both ends, and the throwing amount is 100-1000 / mu. During the breeding period, the water level of the pond was controlled above 60 cm. Before stocking the broodstock shrimps, soak them in pota...

[0019] A method for cultivating Procambarus clarkii in ponds comprises: exposing the pond to the sun for 1 to 2 months before stocking the broodstock, and cleaning and disinfecting the pond. After the clear pond is completed, bury the chicken manure into the bottom of the pond at a depth of 5-30 cm, and use 50-1,000 kg of fertilizer per mu. Into the pool, the amount of fertilizer is 50-200 kg per mu. After the fertilization is completed, water can be injected, the water injection volume is 10-30 cm, and aquatic plants are planted at the bottom of the pond. The coverage rate of aquatic plants is not less than 20% of the total area of ​​the pond. . During the breeding period, the water level of the pond was controlled above 60 cm. Before stocking the broodstock shrimps, soak them in potassium permanganate solution with a concentration of 10-30 mg / L for 5-10 minutes to kill parasites and bacteria; stock the broodstock shrimps with 50-70 kg per mu, and the daily feeding amount i...
