Embodiment 1

[0020] A kind of culture method of mandarin fish comprises the following steps:

[0021] (1) Select a breeding pond: select a pond with a depth of 1.8m, an area of ​​2 mu, and less silt at the bottom of the pond, drain the water in the pond, expose the bottom of the pond to the sun for 10 days, and lay sandy loam with a thickness of 10cm on the bottom of the pond , and grow aquatic plants. The aquatic plants are snapdragon and cress, covering 14% of the total area of ​​the pond. Pretreatment is carried out on the breeding pond before putting in fish fry. The pretreatment is as follows: inject 20cm deep water into the pond, add 4g / L bleaching powder and 20g / L salt, put in quicklime after 7 days for disinfection treatment for 9 days, and the water surface per square meter Sprinkle 80g of quicklime; add water to a depth of 0.8m, put fertilizer into the water after 3 days in the air, and cultivate zooplankton such as rotifers and cladoceras as natural bait. The fertilizer is the...

Embodiment 2

[0026] A kind of culture method of mandarin fish comprises the following steps:

[0027] (1) Select a breeding pond: select a pond with a depth of 2.3m, an area of ​​4 mu, and less silt at the bottom of the pond, drain the water in the pond, expose the bottom of the pond to the sun for 15 days, and lay sandy loam with a thickness of 15cm on the bottom of the pond , and grow aquatic plants. The aquatic plants are Elodea and Erythrina, covering 20% ​​of the total area of ​​the pond. Pretreatment is carried out on the breeding pond before putting in fish fry. The pretreatment is as follows: inject 30cm deep water into the pond, add 6g / L bleaching powder and 25g / L table salt, put in quicklime after 10 days for disinfection treatment for 9 days, and the water surface per square meter Sprinkle 90g of quicklime; add water to a depth of 0.9m, put fertilizer into the water after 5 days in the air, and cultivate zooplankton such as rotifers and cladoceras as natural bait. The fertiliz...

Abstract

The invention relates to the technical field of fish culture, and in particular relates to a breeding method for mandarin fish. The method comprises the following specific steps: (1) selecting a breeding pond: selecting the pond with less sludge at the bottom of the pond, discharging all water in the pond, exposing the bottom of the pond under the sun, spreading sandy loam at the bottom of the pond, and planting aquatic plants; (2) throwing fry: selecting the mandarin fish fry with healthy and strong physique and regular specifications, performing immersion disinfection by using a saline solution, and stocking the disinfected fry; (3) throwing bait: before the bait fish enter the pond, performing immersion disinfection on the bait fish by using a saline solution, and throwing the disinfected bait into the pond; and (4) performing daily management: inspecting the pond every day, observing activity and food intake situations of the mandarin fish, pouring new water every week, and preventing and controlling fish diseases, wherein prevention is first, the prevention and control are combined, and early diagnosis and early treatment are performed. According to the method provided by theinvention, all water in the breeding pond is discharged, and the pond is exposed under the sun, so that bacteria can be effectively killed; when the fry are thrown, the fry are sterilized and the baitis disinfected, so that possibility of diseases of the fry can be effectively reduced, and a survival rate of the fry can be improved; and the method can be widely promoted, and better guarantee market supply and demand of the mandarin fish.

Description

technical field [0001] The invention relates to the technical field of fish farming, in particular to a method for cultivating mandarin fish. Background technique [0002] Mandarin fish is also called mandarin fish, seasonal flower fish, etc. It is a delicacy on the table and is favored by consumers for its tender meat, few spines, delicious taste and rich nutrition. The artificial breeding of mandarin fish generally adopts polyculture or special culture. The survival rate of mixed cultured mandarin fish summer flowers of about 3cm is low, generally only about 20%-40%, but due to the small amount of stocking, the growth rate is faster. The survival rate of breeding in special ponds is high, but the technical requirements are also high, and the stocking density is high, which affects the growth rate. Also do not have a kind of simple, standardized mandarin fish breeding method at present. Contents of the invention [0003] In order to solve the above problems, the invent...
