Problems solved by technology

[0003]Currently, the production of crabs cannot meet the market demand. Although many provinces and cities across the country are developing crab breeding projects, the technology of artificial crab breeding is still far behind Insufficient, people's experience in artificial crab breeding is not perfect
As a result, the size of crabs is relatively small, generally 50-100g, which does not meet the needs of consumers

Embodiment Construction

[0021] The culture method of crab comprises the following steps.

[0022] (1) Choose a pond; choose a water area with good water quality and no pollution, surround it with a fence, and build a pond.

[0023] (2) It is advisable to desilt the dry pond in November to December every year, and it is advisable to leave silt with a depth of 13 to 15 cm. After exposure to the sun, it is thoroughly disinfected with 120Kg / mu of quicklime.

[0024] (3) Set up a plastic shed above the pond.

[0025] (4) Breed small fish in the pond.

[0026] (5) Lay an aeration pipe at the bottom of the pond, the aeration pipe is connected to the aerator, and oxygen is supplied to the pond through the aerator.

[0027] (6) Put photosynthetic bacteria in the pond water; absorb toxic substances in the water through photosynthetic bacteria.

[0028] (7) Plant duckweed, water peanut and Manjianghong in the pond.

[0029] (8) Place 2 crock pots per square meter in the pond.

Abstract

A fresh water crab culturing method belongs to the field of animal culture and especially relates to a crab culturing method. A fresh water crab culturing method with fast crab growing speed and high crab quality is provided. The technical scheme of the fresh water crab culturing method is that a pond is chosen; the pond is pumped and cleaned from November to December each year; after exposure to the sun, 120 kg quicklime is spread on each mu for disinfection; oxygenation pipes are paved on the bottom of the pond; the oxygenation pipes are connected with an oxygenation machine; photosynthetic bacteria is placed in water in the pond; water plants are planted in the pond; a pottery jar is placed in the pond; juvenile crabs are put into the pond in early March; during crab culture, baits are placed once in the morning and evening each day; bait weight weighs 4% to 5% of crab weights; and when the crabs weigh 100 to 150g, the crabs can be caught and sold on the market.

Description

Technical field [0001] The present invention is an animal breeding field, especially the breeding method involving a crab. Background technique [0002] Crab, also known as river crab, is a freshwater crustacean animal. It grows in freshwater. The crab meat is delicious and nutritious.Among the current aquatic products, crabs are one of the most tight aquatic products, with large sales and stable markets. [0003] At present, the production of crabs cannot meet the needs of the market. Although many provinces and cities in the country are developing crab breeding projects, there are many shortcomings of artificial cultivation of crabs, and people's experience in artificial crabs is not perfect.As a result, the specifications of crabs are small, generally 50 to 100g, which does not meet the needs of consumers. Invention content [0004] The present invention is a breeding method of freshwater crab with fast and high crab quality for the above problems. [0005] In order to achiev...
