Problems solved by technology

Folk medicine in my country believes that loach has the effects of strengthening yang and diuresis, treating tuberculosis, and appetizing. The cultivation of loach will have a series of problems such as low survival rate and poor quality of loach in actual operation. At the same time, slow reproduction is relatively slow. Criticism of farmers' breeding enthusiasm

Embodiment 1

[0043] The artificial multiplication method of one generation of paraloach hybridization comprises the following steps:

[0044] parental breeding

[0045] 1. Basic conditions of the pond

[0046] Choose a place with convenient transportation, good water quality, neutral or slightly acidic soil, loamy soil, clay or loess to build the parent pond of paraloach. The pond requires a quiet environment, sufficient water source, and no air pollution, with an area of ​​1000m 2 , east-west direction, the depth of the pond is 100cm, the water level is maintained at 60cm, the depth of silt at the bottom of the pond is 10cm, the drainage system is installed, the water inlet is 0.3m above the water surface, and the drain is equipped with an escape filter.

[0047] 2. Fertilization in clear ponds

[0048] Before the parental ponds are stocked, there are 10 deep water bodies in the ponds, which are disinfected with quicklime, and the dosage is 100kg / 667m 2 After the water is melted, the w...

Embodiment 2

[0079] The artificial multiplication method of one generation of paraloach hybridization comprises the following steps:

[0080] parental breeding

[0081] 1. Basic conditions of the pond

[0082] Choose a place with convenient transportation, good water quality, neutral or slightly acidic soil, loamy soil, clay or loess to build a large scale paraloach parent pond. The pond requires a quiet environment, sufficient water source, and no air pollution, with an area of ​​2000m 2 , east-west direction, the depth of the pond is 200cm, the water level is maintained at 80cm, the depth of silt at the bottom of the pond is 20cm, the drainage system is installed, the water inlet is 0.5m above the water surface, and the outlet is equipped with an escape filter.

[0083] 2. Fertilization in clear ponds

[0084] Before the parental ponds are stocked, 20cm deep water bodies are left in the ponds, and they are disinfected with quicklime at a dosage of 150kg / 667m 2 After the water is melte...

Abstract

An artificial propagation method for paramisgurnus dabryanus first-filial generation relates to the technical field of aquiculture and comprises the following steps: parent cultivation, pond management, artificial propagation, egg laying and hatching and in-time fishing. The artificial propagation method has the benefits that the production resource is fully utilized, special equipment is not required, raising pollution is avoided, the raising technology is standard and normalized, feeding is scientific and normalized, the technology is novel, the aquiculture quality is improved to a great extent, and accordingly, the profit is increased.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to a method for artificial propagation of the first-generation hybridization of Paraloach chinensis. Background technique [0002] Loach is a fish belonging to Cyprinidae, Loachidae, and Loach, and belongs to small economic fish. Loach has high economic value, tender, light and delicious meat, and has nourishing and medicinal value, so it has always been loved by people. It is widely sold in Korea and Japan. Loach mostly inhabits shallow waters such as ponds, ditches, and paddy fields with still water or slightly flowing water. The living environment is not strict. In addition to breathing through the gills, it can also breathe through the skin and intestines. It is an omnivorous fish with partial animal bait. Loach is not only nutritious and delicious, but also has a variety of medicinal effects, so it is called "ginseng in water". Loved by the majority of consumers, the d...
