Embodiment 1

[0008] Embodiment 1 of the present invention: a breeding technology for mud crabs, characterized in that the steps include: breeding equipment: select a location close to the sea, use a water pump to extract seawater, set up water treatment equipment and seawater boilers, and set up a breeding workshop. The heat preservation and shading breeding pool uses a cement pool, inflated and warming measures, and the breeding pool covers an area of ​​10 square meters; Breeding: Select the mated female crab, the carapace width of the back is more than 15 cm, and the weight is 250 grams. The depth of the breeding pool is 50 cm. For shelter, the breeding density is two per square meter, and the water is changed every day. It is transferred to the hatching tank for hatching, using spawning baskets, one female crab is placed in each spawning basket, the water depth is 30 cm, the water temperature is 26 degrees Celsius, the salinity is 2.6%, the light is 1000 lux, the dissolved oxygen per lit...

Embodiment 2

[0009] Embodiment 2 of the present invention: a mud crab breeding technology, characterized in that the steps include: breeding equipment: select a location near the sea, use a water pump to extract seawater, set up water treatment equipment and seawater boilers, set up a breeding workshop, and The heat preservation and shading breeding pool uses a cement pool, inflated and warming measures, and the breeding pool covers an area of ​​10 square meters; Breeding: Select the mated female crab, the carapace width of the back is more than 15 cm, and the weight is 250 grams. The depth of the breeding pool is 50 cm. For shelter, the breeding density is two per square meter, and the water is changed every day. It is transferred to the hatching tank for hatching, using spawning baskets, one female crab is placed in each spawning basket, the water depth is 30 cm, the water temperature is 26 degrees Celsius, the salinity is 2.6%, the light is 1000 lux, the dissolved oxygen per liter of wat...

Embodiment 3

[0010]Embodiment 3 of the present invention: a mud crab cultivation technology, characterized in that the steps include: cultivation equipment: select a location close to the sea, use a water pump to extract seawater, set up water treatment equipment and seawater boilers, and set up a breeding workshop. The heat preservation and shading breeding pool uses a cement pool, inflated and warming measures, and the breeding pool covers an area of ​​10 square meters; Breeding: Select the mated female crab, the carapace width of the back is more than 15 cm, and the weight is 250 grams. The depth of the breeding pool is 50 cm. Shelters, the breeding density is two per square meter, change the water every day, keep the water temperature at 31 degrees Celsius, and the salinity is 3%, and avoid large changes in salinity; spawning and hatching: after the body color of the female crab turns red, put It is transferred to the hatching tank for hatching, using spawning baskets, one female crab i...

Abstract

The present invention discloses a method of cultivating scylla serrata. The scylla serrata cultivation technology has the beneficial effects that (1) the present invention provides a method of systematically cultivating the scylla serrata; and (2) the key point of the scylla serrata cultivation technology is to control water temperature and salinity, and the health rate of the cultivated scylla serrata is high.

Description

technical field [0001] The invention relates to the field of biological breeding, in particular to a breeding technology for mud crabs. Background technique [0002] Scylla serrata belongs to Crustacea, Portunidae. It likes to live in caves in the shallow sea near the coast and in the sandy bottom of the estuary. It is ferocious and carnivorous, and its staple food is fish, shrimp and shellfish. The meat is delicious, nutritious, and has the effect of nourishing and strengthening the body. In particular, female crabs that are about to become pregnant will produce red or yellow cream in their bodies. This is called "cream crab" in southern China, and is known as "sea ginseng". Rich in warm shallow seas, mainly distributed in Zhejiang, Guangdong, Guangxi, Fujian and the coastal areas of Taiwan, especially in Jiangsu and Zhejiang. Nutritional analysis Scylla is rich in protein and trace elements, which has a good nourishing effect on the body. Contents of the invention ...
