Fresh water crab culturing method

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.
