Problems solved by technology

[0002] At present, in the breeding process of juvenile lobster, in order to improve the survival rate and growth rate of juvenile shrimp, a lot of preparation work will be done before the juvenile shrimp is stocked, from water quality to the adaptability of the juvenile shrimp itself, but the survival rate of juvenile shrimp is still It is very low, generally around 60%, and it is difficult to reach 80%, which brings great economic losses to farmers. Therefore, improving the survival rate of juvenile shrimp is a major problem that needs to be solved urgently in the current lobster farming process

Embodiment 1

[0018] An efficient breeding method of lobster juvenile shrimps specifically includes the following steps:

[0019] (1) Shrimp pond construction: the pond ridge of the shrimp pond is constructed with cement, and a medicine cave is set up on the pond ridge, and the mud ridge is built along the pond ridge, 1.6~1.8m away from the pond ridge, and the particle size of the medicine cave is 1.2~1.4cm Zeolite, adsorb toxic substances, clean water quality;

[0020] (2) Pond water disinfection: 2 days before the stocking of juvenile shrimp, inject river water into the shrimp pond, with a water depth of 0.7m, a water temperature of 28~30℃, and a dissolved oxygen content of 7~8mg / L. After that, the pond will be cleared every 30 days. Then sprinkle 22kg / mu of dry lime, disinfect the dry pond for 20 hours and then wash the dry pond clean. Use a filter with a pore size of 0.2cm when filling the water. Sprinkle the disinfectant evenly in the water every 5 days. 10g / mu, disinfect regularly to inhi...

Embodiment 2

[0030] An efficient breeding method of lobster juvenile shrimps specifically includes the following steps:

[0031] (1) Shrimp pond construction: the pond ridge of the shrimp pond is constructed with cement, and a medicine cave is set up on the pond ridge, and the mud ridge is built along the pond ridge, 1.6~1.8m away from the pond ridge, and the particle size of the medicine cave is 1.2~1.4cm Zeolite, adsorb toxic substances, clean water quality;

[0032] (2) Pond water disinfection: 2 days before the stocking of juvenile shrimps, inject river water into the shrimp pond with a water depth of 0.8m, a water temperature of 28~30℃, and a dissolved oxygen content of 7~8mg / L. Afterwards, the pond will be cleared every 33 days. Then sprinkle 23kg / mu of dry lime, disinfect the dry pond for 21 hours and then wash the dry pond clean. Use a filter with a pore size of 0.3cm when filling the water. Sprinkle disinfectant into the water evenly every 5 days. 11g / mu, disinfect regularly to inhibi...

Embodiment 3

[0042] An efficient breeding method for lobster juvenile shrimps specifically includes the following steps:

[0043] (1) Shrimp pond construction: the pond ridge of the shrimp pond is constructed with cement, and a medicine cave is set up on the pond ridge, and the mud ridge is built along the pond ridge, 1.6~1.8m away from the pond ridge, and the particle size of the medicine cave is 1.2~1.4cm Zeolite, adsorb toxic substances, clean water quality;

[0044] (2) Pond water disinfection: 3 days before the stocking of juvenile shrimps, river water is injected into the shrimp pond, the water depth is 0.9m, the water temperature is 28~30℃, and the dissolved oxygen content is 7~8mg / L. After that, the pond will be cleared every 35 days. Then sprinkle 24kg / mu of dry lime, disinfect the dry pond for 22 hours and then wash the dry pond clean. Use a filter with a pore size of 0.4cm when filling the water. Sprinkle disinfectant into the water evenly every 5 days. 12g / mu, regular disinfection ...

Abstract

The invention discloses an efficient breeding method for young lobsters, comprising the steps of: (1) constructing a lobster pond; (2) sterilizing water in the pond; (3) breeding young lobsters; (4) feeding the young lobsters with a young fodder; and (5) performing daily management. By adopting the efficient breeding method for young lobsters, the immunity of the young lobsters can be strengthened, the morbidity rate is reduced to 3%, and the survival rate reaches 92%; comprehensive management is performed from five aspects of construction of the lobster pond, sterilization of pond water, breeding of young lobsters, feeding with the fodder and daily management, the lobster pond is provided with agent holes for placing zeolite, and medical stone is added to the clay ridges, so that toxin can be adsorbed and water can be cleaned; the pond is cleared and disinfected within a fixed time, so that germs are killed thoroughly; the young lobsters are disinfected before being bred and fed with a special fodder for lobsters three times, and planktons are not bred, so that scientific proportioning of the young lobster fodder is ensured, the water is clean, and reproduction of pathogenic microorganisms is inhibited; the pond is inspected every day to discover and early treat symptoms, thereby avoiding high loss and improving the economic income by 16.4%.

Description

Technical field [0001] The invention mainly relates to the field of breeding technology, in particular to a method for efficiently breeding lobster juveniles. Background technique [0002] At present, in the breeding process of lobster juvenile shrimp, in order to improve the survival rate and growth rate of juvenile shrimp, a lot of preparation work is done before stocking of juvenile shrimp, from water quality to the adaptability of juvenile shrimp itself, but the survival rate of juvenile shrimp is still It is very low, generally around 60%, and it is difficult to reach 80%, which brings great economic losses to farmers. Therefore, improving the survival rate of juvenile shrimp is a major problem that needs to be solved urgently in the process of lobster breeding. Summary of the invention [0003] In order to make up for the defects of the prior art, the purpose of the present invention is to provide an efficient breeding method for lobster juveniles. [0004] An efficient breed...
