How much do Australian freshwater crayfish seedlings cost?

Good breeding varieties - Australian freshwater lobster Australian freshwater lobster, also known as red claw crayfish, belongs to the family of Decapoda, and is a large freshwater crayfish native to Australia. In recent years, the shrimp has been introduced and tested in Guangdong Province, and has achieved success in artificial breeding of seedlings and adult shrimp breeding. It is currently being promoted in and outside the province. Recently, Zhanjiang Special Aquatic Products Co., Ltd. took the lead in the country to successfully carry out indoor factory breeding of Australian freshwater lobster seedlings, and bred more than 400,000 shrimp seedlings for rural farmers in the province and Shanghai, Jiangsu, and Zhejiang to raise them, solving the seedling problem for the development of the shrimp. Australian freshwater lobsters are called freshwater lobsters because they are large in size and look a bit like sea lobsters, and they only live in fresh water. Their individuals generally weigh 100 to 200 grams, and the largest individuals in Australia can weigh up to 500 grams. It has a beautiful appearance, brown-green body color, evenly connected head and chest and abdomen, a hard shell on the outside, and 5 pairs of thoracic feet. The first pair of thoracic feet is particularly developed and becomes a powerful claw. The male claw is more developed than the female claw. There is a membranous bright red band on the outside of the claw. There are 6 tentacles on its head and 5 tail fans on its tail. Therefore, the Australian freshwater lobster looks majestic and beautiful, and therefore has ornamental value. According to research, the Australian freshwater lobster is one of the world's precious economic shrimp species. It likes darkness and fears light by nature. It is good at crawling and living in the clear, but not good at swimming. It usually hides in deep water caves during the day and starts to move in the evening after the sun sets. Most of them gather in shallow water to crawl and forage for food and mates. If frightened, they will quickly escape back to deep water. It requires fresh water to live, likes fresh running water, and is slightly salty. It also likes to swim upstream. It has strong adaptability and can survive in water temperatures of 15 to 35 degrees Celsius. It can tolerate harsh climates and environments. It can survive summer and winter normally under normal conditions. When it encounters an unsuitable environment, it can also climb onto the pond to live on land. This shrimp has a mixed diet, eating both animal bait and artificial feed. It can be raised intensively or roughly. According to breeding, the shrimp grows fast, has a high survival rate, and has a high yield. It can reach sexual maturity in one year of breeding in South China. It can be harvested and put on the market in the same year it is released. If the artificial breeding is well managed, the yield per mu can reach more than 400 kilograms. Australian freshwater lobsters are large and plump, rich in nutrients, tender and crispy, delicious and sweet, and have a unique flavor. They are quite popular with diners at home and abroad. What's more rare is that Australian freshwater lobsters can be listed in the winter after Chinese shrimps, giant tiger shrimps, black shrimps, white shrimps and other marine shrimps are harvested and put on the market, so the goods are in short supply and the price is good. In addition, it is durable and suitable for long-distance transportation. It can be supplied live in markets, restaurants and hotels, and can also be exported to the international market. Therefore, Australian freshwater crayfish farming has a good development prospect. Red claw crayfish English name: Red claw Common name: freshwater crayfish, crayfish Origin and production period: Originally from Australia, since the late 1980s, it has been exported to many countries such as the United Kingdom, France, Spain, South Africa, Zimbabwe, Japan, and Southeast Asia. Introduction: The entire body of the red claw crayfish consists of the cephalothorax and abdomen covered with chitinous carapace. There are 20 segments in the body, and 13 segments in the cephalothorax. The cephalothorax protects the internal organs. There is a forehead sword extending forward in front of the cephalothorax, with 3 to 4 spines on each side. There are 4 ridges on the back of the cephalothorax arranged along the longitudinal axis of the body. Both eyes are stalked and protruding. There are 5 pairs of walking legs on the cephalothorax. The first pair is a thick and large claw. The male's large claw has a beautiful membrane-like bright red patch on the outside. The second and third pairs of walking legs are in the shape of claws, and the fourth and fifth pairs of walking legs are in the shape of claws. The abdomen has 7 segments. Although it is covered with a carapace, the intersegments are connected by fibrous membranes, which can move flexibly. There is a pair of appendages under the second to fifth abdominal segments, called gastropods or swimming feet. The appendages of the sixth abdominal segment extend backwards and widen to form a tail foot, which forms a tail fan with the tail segment, which is the crayfish's fast movement organ. There are also 3 pairs of antennae at the front of the cephalothorax, 1 pair of large antennae and 2 pairs of small antennae. Red claw crayfish can live in rivers, lakes, reservoirs, and ponds. They lurk in hidden places in the water during the day and come out to forage in the evening and before dawn. They like to move at night and live a bottom-dwelling crawling life. They often crawl in the gaps between bricks, tiles and gravel or lurk in natural and artificial caves in ponds. They have the ability to dig holes in the soft bottom of ponds. Sometimes they also crawl along the wall of ponds or lurk in the roots and dense leaves of aquatic plants.

The current market price is 1.5 yuan/tail for 2-3cm; 2.5 yuan/tail for 5-8cm. Almost all the seedlings on the market are 2-3cm. Cultivation of too small requires very high technology; while the cultivation cost of 5-8cm is high, but the survival rate is high.
