Problems solved by technology

Scientists from Osaka University in Japan found that astaxanthin in shrimp can help eliminate the "jet lag" caused by jet lag. Due to the high value of lobster, there will always be a shortage of supply in the market, so the artificial breeding of lobster It is currently on the rise, but the lobster farming technology is still relatively traditional, and the survival rate of farming is extremely low, which severely criticizes the farmers' desire and enthusiasm for farming.

Embodiment 1

[0020] A technical method for cultivating freshwater lobsters in ponds, comprising the following steps:

[0021] (1), Pond conditions:

[0022] Choose a place with ventilation and sunshine, soil quality and water retention, and no pollution to the water source to build the pond. The size of the pond is 10 mu, the water depth reaches 1.5 meters, the bottom of the pond is flat and set as a sandy mud bottom, the slope ratio of the pond to dam is 1:4, and some parts are planted in the pond Aquatic plants or put stones, bricks, tiles, the area accounts for about 1 / 3 of the total water surface.

[0023] (2), stocking of shrimp seedlings:

[0024] Before stocking, disinfect the clear pond with 150 kg / mu of quicklime, enter the water after 3 days of disinfection, and use 500 kg / mu of fermented and decomposed organic fertilizer and water after 10 days. Select the shrimp seedlings with a body length of 5 cm, strong physique, and no disease. The density is 3000 tails / acre, and the seed...

The technical method for culturing the freshwater crayfish in the pond has the advantages of fully utilizing production resources, and being free of professional equipment and cultivating pollution, standard and norm in breeding technology, scientific and norm in feeding and novel in co-culture technique, improving the quality of aquaculture to the largest extent and the benefit of crayfish.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to a technical method for cultivating freshwater lobsters in ponds. Background technique [0002] Lobster is a general term for 19 species of lobsters belonging to 4 genera of the cetaceae Decapod Lobster family Arthropoda. Also known as prawns, faucet shrimps, shrimp heads, sea shrimps, etc. It has a thick head and chest, a hard shell, colorful colors, a short abdomen, a body length of 20 cm to 40 cm, and a weight of about 0.5 kg. It is the largest type of shrimp. The heaviest can reach more than 5 kilograms, known as the lobster tiger. The body is thick and cylindrical, the back and abdomen are slightly flat, the carapace is well developed, thick and spiny, and there is a pair of powerful spines on the eyes in the center of the front edge, with closed gill chambers. The important astaxanthin in the lobster is scientific One of the strongest antioxidants ever found, the dark...
