Australian freshwater lobster, also known as red crayfish, is a large freshwater crayfish, which belongs to the family Decapoda, and is native to Australia. In recent years, this shrimp has been introduced to Guangdong Province for trial culture, and has successively achieved the success of artificial propagation of seedlings and adult shrimp culture. At present, it is being promoted in and out of Guangdong Province. Recently, Zhanjiang Special Aquatic Products Co., Ltd. took the lead in indoor factory breeding of Australian freshwater lobster fry in China, and successfully bred more than 4, shrimp fry for rural farmers in the province and Shanghai, Jiangsu and Zhejiang to solve the seedling problem for the development of this shrimp.
Australian freshwater lobster is called freshwater lobster because of its large size, somewhat similar appearance to sea lobster and only living in fresh water. Its individual generally weighs 1 ~ 2 grams, and the largest individual in Australia can weigh 5 grams. Its appearance is beautiful, its body color is brown-green, its head, chest and abdomen are evenly connected, and it is covered by a hard shell, and it has 5 pairs of chest feet, which are covered by a hard shell and 5 pairs of chest feet. The first pair of chest feet is particularly developed and becomes a powerful claw. The male's claw is more developed than the female's, and there is a bright red membrane band on the outside of the claw, while its head has 6 tentacles and its tail has 5 tail fans, so the Australian freshwater lobster looks mighty and powerful.
According to research, Australian freshwater lobster is one of the rare economic shrimp species in the world. It is naturally fond of darkness and afraid of light, good at crawling and not good at swimming. Usually they hide in deep-water 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 their spouses. If they are frightened, they quickly flee back to deep water. Its life requires fresh water, likes fresh water and fresh water, is slightly salty, and likes to go upstream; Strong adaptability, the water temperature can survive at 15 ~ 35℃, and it can tolerate harsh climatic environment. Under general conditions, it can spend the summer and winter normally, and when the environment is not suitable, it can climb up the pond to live on land. This kind of shrimp is omnivorous, eating both animal bait and artificial feed, which can be cultivated intensively or coarsely. According to the culture, the shrimp grows fast, has a high survival rate and high yield. It can be matured after being cultured in South China for one year, and can be harvested and marketed in the same year of stocking. The artificial culture management is good, and the yield per mu can reach more than 4 kilograms.
Australian freshwater lobster is big and fat, rich in nutrition, tender and crisp in meat, delicious and sweet, and has a unique flavor, which is very popular among diners at home and abroad. What is even more rare is that Australian freshwater lobsters can be arranged to be listed in the winter after the harvest of China prawns, Penaeus monodon, Moji prawns, white prawns and other marine prawns, so the goods are in good demand. In addition, it is resistant to live, suitable for long-distance transportation, can supply live shrimp 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.
