Problems solved by technology

It is delicious, nutritious, and has high economic value. Due to the high value of adult crabs, there will always be a shortage of supply in the market. Therefore, artificial breeding of adult crabs is currently on the rise, but the breeding technology of adult crabs is still relatively traditional. The survival rate of breeding is extremely low, which seriously criticizes the farmers' desire and enthusiasm for breeding

Embodiment 1

[0024] A technical method for growing crabs in paddy fields, comprising the following steps:

[0025] (1), field engineering:

[0026] ①. Choose a field with a quiet environment, sufficient water source, good water quality, no industrial pollution, convenient drainage, no flooding, no drought, and strong water retention. The ridges are solid and not collapsed, with a width of 1.5 meters. With an area of ​​8 mu, dig a ring ditch 2 meters away from the inner side of the ridge, 1 meter wide, 1.0 m deep, and a slope of 1:1.2. Dig a "ten" or "well" shaped box ditch. The box ditch is connected to the outer ring ditch, and the box surface is planted Rice and crabs are raised in the ditch. At one end of the field, build a temporary pond with a depth of 1.5 meters and occupy 5% of the field area. Field works account for 15% of the paddy field area. The inlet and outlet outlets are arranged diagonally, and aquatic plants are planted in ditches and pools, and the coverage is controll...

Embodiment 2

[0040] A technical method for growing crabs in paddy fields, characterized in that: comprising the following steps:

[0041] (1), field engineering:

[0042] ①. Choose a field with a quiet environment, sufficient water source, good water quality, no industrial pollution, convenient drainage, no flooding, no drought, and strong water retention. The ridges are solid and not collapsed, with a width of 3.0 meters. With an area of ​​10 mu, dig a ring ditch 3 meters away from the inner side of the field ridge, 2 meters wide, 1.0 m deep, and a slope of 1:1.2. Dig a "ten" or "well"-shaped box ditch. The box ditch is connected with the outer ring ditch, and the box surface is planted Rice and crabs are raised in the ditch. At one end of the field, build a temporary pond with a depth of 1.5 meters and occupy 5% of the field area. Field works account for 20% of the paddy field area. The inlet and outlet outlets are arranged diagonally, and aquatic plants are planted in ditches and po...

Abstract

The invention relates to a paddy field adult crab breeding technical method and belongs to the technical field of aquaculture. The method includes the steps of field engineering, crab larvae putting for breeding, feeding and management, disease prevention and timely crabbing. The paddy field adult crab breeding technical method has the advantages of being making full use of production resources, needing no professional equipment, being free from breeding pollution, standard in breeding technology, scientific and standard in feed feeding and novel in polyculture technology, greatly improving the quality of aquaculture and accordingly increasing the earnings of adult crabs.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to a technical method for cultivating adult crabs in paddy fields. Background technique [0002] Adult crabs, also known as "hair crabs", are crustaceans in the phylum Arthropoda. The carapace formed by the combination of the head and the chest is square and hard. There is a pair of eyes on the front of the body, and two pairs of very sharp crab teeth on the side. The first pair of appendages of the crab are called chelicerae, and the surface is covered with fluff; behind the chelicerae, there are 4 pairs of walking legs, with flat sides and longer; the abdominal limbs have degenerated. Male and female adult crabs can be distinguished from their abdomen: the abdomen of the female is round, and the abdomen of the male is triangular. It is delicious, nutritious, and has high economic value. Due to the high value of adult crabs, there will always be a shortage of supply in the m...
