Australian freshwater lobster, also known as red lobster, belongs to the family of decapod crayfish. It is a large freshwater crayfish, native to Australia. In recent years, this kind of shrimp has been introduced to Guangdong Province for trial planting, and has achieved the success of artificial breeding and adult shrimp culture. At present, it is being promoted inside and outside Guangdong Province. Recently, Zhanjiang Special Aquatic Products Co., Ltd. took the lead in carrying out indoor factory breeding of Australian freshwater lobster fry in China, and successfully bred more than 400,000 shrimp fry for farmers in the whole province and rural areas of Shanghai, Jiangsu and Zhejiang, thus solving the seedling problem for the development of this shrimp.

Australian freshwater lobster is called freshwater lobster because it is very big, looks a bit like sea lobster, and only lives in fresh water. Its individual generally weighs100 ~ 200g, and the largest individual in Australia can reach 500g. Beautiful appearance, brown-green body color, head, chest, abdomen evenly connected, wrapped by a hard shell, there are 5 pairs of chest feet, wrapped by a hard shell. The first pair of pectoral feet are particularly developed and become powerful claws. Male claws are more developed than female claws, with 1 bright red film ribbon on the outside, 6 tentacles on the head and 5 tail fans on the tail.

According to research, Australian freshwater lobster is one of the rare economic shrimp species in the world. It is naturally fond of the dark and afraid of light. It is good at crawling and not good at swimming. Usually they hide in deep caves during the day and start to move after sunset in the evening. Most of them gather in shallow water to crawl for food and find a mate. If frightened, they will quickly flee back to deep water. Its life needs fresh water, like fresh water, slightly salty, like upstream; Strong adaptability, the water temperature can survive at 15 ~ 35℃, and can endure the harsh climate environment. Under normal circumstances, I can spend the Xia Dong normally, and when the environment is not suitable, I can climb the land near the pond to live. This kind of shrimp is omnivorous, eating both animal bait and artificial feed, which can be intensively raised or coarsely raised. According to the culture of the invention, the shrimp grows fast, the survival rate is high and the yield is high. It can be matured after one year of cultivation in South China, and can be harvested and marketed in the same year of stocking. Artificial cultivation management is good, and the yield per mu can reach more than 400 kg.

Australian freshwater lobster is big and fat, rich in nutrition, tender and crisp in meat, delicious and sweet in taste and unique in flavor, which is deeply loved by diners at home and abroad. What's even more rare is that Australian freshwater lobsters can be listed in the winter after the harvest of China shrimp, Penaeus monodon, Moji shrimp and white shrimp, so the supply is very good. In addition, it is resistant to live, suitable for long-distance transportation, can supply live shrimps in markets, restaurants and restaurants, and can also be exported to the international market, so freshwater lobster culture in Australia has a good development prospect.

Red claw crayfish

English name: Red claw

Common name: freshwater lobster, crayfish

Origin and delivery date:

Originated in Australia, it has been exported to Britain, France, Spain, South Africa, Zimbabwe, Japan, Southeast Asia and other countries since the late 1980s.

Introduction:

The whole body of red crayfish consists of three parts: head, chest and abdomen. The head and chest each have 20 knots, 13 knots. Head breastplate protects internal organs. There is a frontal sword extending forward in front of the head breastplate, and there are 3 ~ 4 thorns on both sides. There are four ridges arranged along the longitudinal axis of the body on the back of the head breastplate. The eyes have stalks and protrude outward. There are five pairs of feet on the head and chest, 1 pair is thick claws, and there are bright red and beautiful patches on the outside of the male big claws. The second and third pairs of feet are claw-shaped, and the fourth and fifth pairs of feet are claw-shaped. The abdomen has seven sections, which are covered with crustaceans, but the joints are connected by fibrous membranes and can move flexibly. There are 1 pairs of appendages under the second to fifth abdominal segments, which are called abdominal feet or swimming feet. The sixth appendage of the abdomen extends backward, which widens the caudal foot and forms a caudal fan with the caudal segment. It is a fast moving organ of crayfish. There are 3 pairs of antennae, 1 pair of big antennae and 2 pairs of small antennae at the front end of the head and chest. Red crayfish can live in rivers, lakes, reservoirs and ponds, lurk in hidden places in the water during the day, come out for food in the evening and before dawn, like to move at night, and live and crawl on the seabed. Often crawling in the cracks between bricks and gravel or lurking in natural caves and artificial caves in ponds, it has the ability to dig holes in the soft bottom of ponds. Sometimes it will climb or crouch along the pool wall in the roots and dense leaves of aquatic plants.
