Problems solved by technology

In crayfish farming, during the peak growth season, especially in summer, the water temperature is high, the remaining feed is not easy to remove, and the water quality is easy to deteriorate, which affects growth or causes diseases
For example, the outbreak of cyanobacteria and viral diseases caused by food pollution in water quality in summer is an important reason for the death of crayfish, causing many farmers to waste feed and spend a lot of money on water transfer and treatment

Embodiment 1

[0085] A method for ecologically mixed cultivation of squid and crayfish, the cultivation method comprising the steps of:

[0086] (1) Pond preparation

[0087] The pond is rectangular, with an area of ​​10 mu, running north-south, with an aspect ratio of 4:3. An inland beach is set in the middle of the pond, and a ring ditch with a depth of 0.5 m is set around the inland beach for concealed shelling of crayfish and high-temperature summer escape. . A water inlet and a water outlet are arranged at the bottom of the pond mouth, and the water inlet and the water outlet are arranged diagonally, and the water outlet is lower than the water inlet, so as to facilitate the discharge of sewage at the bottom of the pond. The depth of the pool is 1 m, and the slope ratio of the pool wall is 1:2.

[0088] (2) Preparation of facilities

[0089] Facility preparations include anti-escape facilities and oxygenation facilities. The anti-escape facilities are wooden pile enclosure structure...

Embodiment 2

[0106] A method for ecologically mixed cultivation of squid and crayfish, the cultivation method comprising the steps of:

[0107] (1) Pond preparation

[0108] The pond is rectangular, with an area of ​​45 mu, running north-south, 245 m long and 123 m wide. An inland beach is set in the middle of the pond, and a ring ditch with a width of 3 m and a depth of 0.5 m is set around it. The water inlet and outlet are arranged at the bottom of the pond mouth. The water inlet and outlet are arranged diagonally, and the outlet is lower than the water inlet. 1 m, pool wall slope ratio 1:2;

[0109] (2) Facility preparation

[0110] Facility preparations include escape prevention facilities and oxygenation facilities. The escape prevention facilities are wooden pile enclosure structures inserted symmetrically on the inner side of the pool ridge with a plastic film sandwiched between them. The height of the wooden piles is 40 cm, and the spacing is 50 cm, and the height of the plastic...

[0127] A method for ecologically mixed cultivation of squid and crayfish, the cultivation method comprising the steps of:

[0128] (1) Pond preparation

[0129] The pond is rectangular, with an area of ​​30 mu, running north-south, and an old pond with an aspect ratio of 4:3. An inland beach is set in the middle of the pond, and a ring ditch with a width of 3 m and a depth of 0.5 m is set around it. The outlet, the water inlet and the outlet are arranged diagonally, and the outlet is lower than the water inlet, the depth of the pool is 1 m, and the slope ratio of the pool wall is 1:2;

[0130] (2) Facility preparation

[0131] Facility preparations include escape prevention facilities and oxygenation facilities. The escape prevention facilities are wooden pile enclosure structures inserted symmetrically on the inner side of the pool ridge with a plastic film sandwiched between them. The height of the wooden piles is 40 cm, and the spacing is 50 cm, and the height of the plas...

Abstract

The invention discloses an ecological mixed aquaculture method for bitterling and crayfish. The aquaculture method comprises the following steps of preparing a pond, preparing facilities, establishing an ecological environment, stocking the bitterling, stocking the crayfish, feeding baits, carrying out disease control and prevention, catching and harvesting. The invention provides a bait matching method for crayfish aquaculture; the bitterling and the crayfish are mixed in the same water body and water layer serving as natural live baits for ecological mixed aquaculture, so that the bait matching problem for the crayfish is solved, the environment is stabilized, and the purpose of healthy aquaculture of an ecological cycle is achieved. Through implementation of the invention, the method has the advantages of practical technology, low cost, environmental-friendly aquaculture and capability of effectively improving the yield and the composite economic benefit of the crayfish.

Description

technical field [0001] The invention relates to a method for polyculture of aquaculture species, in particular to a method for ecologically mixed culturing of squid and crayfish, and belongs to the technical field of aquaculture. Background technique [0002] The squid belongs to the subfamily Acheilognathinae (Cyprinidae) of Cypriniformes (Cypriniformes). Other freshwater basins other than the Heilongjiang water system in China. The squid is a natural wild fish with rich natural resources. Its meat is delicious and easy to catch. It is a large number of fish catches, and it is some small fish that people like to eat. There are many types of scallops, such as scallops chinensis and scorpion scorpions, which are famous native ornamental fish in China. Their beautiful shapes and bright colors are deeply loved by the majority of ornamental fish breeding enthusiasts. Seaweed entered Europe as an ornamental fish in the 1960s and was known as the Chinese rainbow. Anchovy is an ...
