Embodiment 1

[0025] Present embodiment provides a kind of method of cultivating freshwater perch seed, comprises the steps:

[0026] (1) The pretreatment of holding pond temporarily: select salinity to be in the temporarily holding pond of 5 ‰, drop into water quality improving agent in holding pond temporarily, put in once every 5 days, every 15 kilograms of fish puts in 4g water quality improving agent;

[0027] (2) Temporary raising: put the perch fry with a body length of 1.5-2 cm into the temporary raising pond, and add Chinese medicine extract every day for the first 3 days of feeding;

[0028] (3) Feeding food: when the fry are temporarily raised, it is necessary to increase oxygen in the pool water; on the second day after stocking, some red worms are fed, and then artificial feed is put in. The daily feeding amount of artificial feed accounts for 10% of the total fish weight. 0.5%, the artificial feed is mainly made of the following raw materials in parts by weight: 25 parts of so...

Embodiment 2

[0034] Present embodiment provides a kind of method of cultivating freshwater perch seed, comprises the steps:

[0035] (1) The pretreatment of temporary raising pond: select the temporary raising pond with salinity as 4 ‰, drop into water quality improving agent in temporary raising pond, put in once every 5 days, put in 5g water quality improving agent for every 20 kilograms of fish;

[0036] (2) Temporary raising: put the perch fry with a body length of 1.5-2 cm into the temporary raising pond, and add Chinese medicine extract every day for the first 3 days of feeding;

[0037] (3) Feeding food: when the fry are temporarily raised, it is necessary to increase oxygen in the pool water; on the second day after stocking, some red worms are fed, and then artificial feed is put in. The daily feeding amount of artificial feed accounts for 10% of the total fish weight. 0.1%, the artificial feed is mainly made of the following raw materials in parts by weight: 20 parts of soybean m...

Embodiment 3

[0043] Present embodiment provides a kind of method of cultivating freshwater perch seed, comprises the steps:

[0044] (1) The pretreatment of temporary raising pond: select the temporary raising pond with salinity as 7 ‰, put into the water quality improving agent in the temporary raising pond, put in once every 5 days, put in 2g water quality improving agent for every 10 kilograms of fish;

[0045] (2) Temporary raising: put the perch fry with a body length of 1.5-2 cm into the temporary raising pond, and add Chinese medicine extract every day for the first 3 days of feeding;

[0046] (3) Feeding food: when the fry are temporarily raised, it is necessary to increase oxygen in the pool water; on the second day after stocking, some red worms are fed, and then artificial feed is put in. The daily feeding amount of artificial feed accounts for 10% of the total fish weight. 0.8%, the artificial feed is mainly made of the following raw materials in parts by weight: 20-30 parts of...

Abstract

The invention discloses a method for cultivating freshwater weever fries, and belongs to the technical field of aquaculture. The method includes the following steps: pretreating a holding pond; putting the weever fries, 1.5-2 cm in length, into the holding pond, and adding traditional Chinese medicinal extraction liquid everyday 3 days before feeding; during temporary breeding of the fries, increasing oxygen in pond water frequently; on the second day for free-range breeding, feeding some blood worms, and feeding artificial feed, wherein the daily feeding amount of the artificial feed accountsfor 0.1-0.8% of the total fish weight; after breeding the fries in the holding pond for 20-30 days, breeding fishes with the body length of more than 5 cm in a large pond. The method has the advantages that the special breeding feed is used for raising, the nutritive value of cultivated weevers is high, all nutrition requirements for high-density culture of the freshwater weevers can be met, cultivated objects grow rapidly, and the feed conversion rate and the cultivation efficiency are high.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to a method for cultivating freshwater perch fry. Background technique [0002] Sea bass contains nutrients such as protein, fat, carbohydrates, and vitamin B 2 , niacin and trace amounts of vitamin B1, phosphorus, iron and other substances, have high edible and medicinal value. From the living habits of perch, we can know that perch can live in both sea water and fresh water, so it is called freshwater perch. In recent years, desalinated perch fry have been successfully scaled in freshwater fish ponds, becoming a large-scale freshwater cultured high-quality economic fish after tilapia, and the main cultured species in freshwater farming areas, effectively improving the efficiency of freshwater farming and driving poverty Development of aquaculture in mountainous areas. [0003] Freshwater perch has the characteristics of fast growth, wide adaptability, strong disease resista...
