Problems solved by technology

However, due to factors such as the soil quality, environment, and water source of the mud-bottom pond, the perch produced mostly has the muddy smell unique to freshwater fish, which does not meet the requirements for raw materials for aquatic product processing, and has become a bottleneck for the industrialization of freshwater aquaculture perch.
[0004] The grouper has a beautiful appearance, delicious meat and rich nutrition. It can be used as a commercial fish or as an ornamental fish. The wild grouper is relatively small and feeds on plankton and insect aquatic larvae attached to the stone wall. The growth rate is slow, but it is resistant to low oxygen and has strong disease resistance. If artificial breeding can be carried out, it will bring greater economic benefits

Embodiment 1

[0021] 1) Pond selection and treatment: The pond is rectangular in shape, north-south, and the depth of the pond is 2.4 meters. A water inlet pipe is arranged at the bottom of the pond, and the pond is disinfected. Disinfect the pond with quicklime and clean the pond with clear water. Layer 30cm thick pond silt, plant aquatic plants on the silt, and then put it into clean and pollution-free water;

[0022] 2) Pool water treatment: the water quality is controlled between pH 5 and 6.5, the water depth is 80cm when the fry are put in, and then water is added every 3 days, 10cm each time, so that the water depth reaches 200cm, and small rows are used for small feeding and multiple replacements. The method of water is used to control the water quality, and the mixed liquid is added and drained every day 2 months before the perch is listed. The mixed liquid is tea, agave, tangerine peel and water, which are steamed and boiled according to the mass ratio of 1:500, and boiled 3 times. ...

Embodiment 2

[0028] A culture method for freshwater perch, comprising the following steps:

[0029] 1) Pond selection and treatment: The pond is rectangular in shape, north-south, and the depth of the pond is 2.2 meters. A water inlet pipe is arranged at the bottom of the pond, and the pond is disinfected. Disinfect with quicklime and clean the pond with clear water. Layer 40cm thick pond silt, plant aquatic plants on the silt, and then put it into clean and pollution-free water;

[0030] 2) Pool water treatment: the water quality is controlled between pH 5 and 6.5, the water depth is 75cm when the fry are put in, and then water is added every 4 days, adding water 12cm each time, so that the water depth reaches 180cm, and small rows are used for small feeding and multiple replacements. The method of water is used to control the water quality, and the mixed liquid is added and drained every day 1.5 months before the perch is listed. The mixed liquid is tea, agave, tangerine peel and water, ...

Embodiment 3

[0036] A culture method for freshwater perch, comprising the following steps:

[0037] 1) Pond selection and treatment: The pond is rectangular in shape, north-south, and the depth of the pond is 2.6 meters. A water inlet pipe is arranged at the bottom of the pond, and the pond is disinfected. Disinfect the pond with quicklime and clean the pond with clear water. Layer 35cm thick pond silt, plant aquatic plants on the silt, and then put it into clean and pollution-free water;

[0038] 2) Pool water treatment: the water quality is controlled between pH 5 and 6.5, the water depth is 70cm when the fry are put in, and then water is added every 5 days, 15cm each time, so that the water depth reaches 200cm, and small rows are used for small feeding and multiple replacements. The water method is used to control the water quality. One month before the sea bass is listed, the mixed liquid is added and drained every day. The mixed liquid is tea, agave, tangerine peel and water, which ar...

Abstract

The invention discloses a breeding method of weever in fresh water. The method includes the following steps of (1) selection and treatment of a pond, wherein the pond is rectangular and is arranged inthe north-south direction, quick lime is used for disinfection, clean water is used for cleaning the pond, a layer of pond silt with the thickness of 30-40 cm is laid on the bottom of the pond, aquatic plants are planted on the silt, and then clean water free of pollution is put into the pond; (2) treatment of pond water, wherein the water quality is controlled within the pH range from 5 to 6.5,addition of mixed liquid and drainage are conducted every day 1-2 months before the weever can be sold in the market, and the mixed liquid is filtered liquid of tea leaves, maguey and pericarpium citri reticulatae which are stewed, filtered and cooled; (3) stocking of the weever; (4) feed feeding. The weever obtained by means of the method is delicious in taste and high in protein content, the mudsmell of the weever bred in the fresh water can be removed, and the requirements of processing raw materials are met.

Description

technical field [0001] The invention belongs to the technical field of freshwater fish cultivation, and in particular relates to a method for cultivating freshwater perch. Background technique [0002] Perch meat is fresh and tender, white in color and high in nutritional value. It is a high-quality raw material for processing high-value products. Bass grows in the waters between sea and freshwater, and it is a fish that can be reversed in sea and freshwater. 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] Most of the freshwater aquaculture in mountainous areas are relatively primitive mud-bottom ponds. The natural ecological environment of the ponds ...
