How much does Australian lobster cost per jin? Detailed explanation of farming techniques
The scientific name of the Australian lobster is the Australian rock lobster. It is a relatively large freshwater shrimp that is deeply loved by people because of its abundant meat and delicious taste. However, because the price is very expensive, many people only buy it to eat when it is in season. So approximately how much does Australian lobster cost per jin? What are the farming techniques?
1. Introduction to Australian lobster:
1. Where are Australian lobsters distributed?
Australian lobsters are mainly distributed in subtropical and tropical regions, and are generally more common on Tasmania Island in Australia. At present, farming has also begun in New Zealand, the United States, Africa, South Asia and other places.
2. What do Australian lobsters eat to grow?
Australian lobsters have omnivorous feeding habits. They eat animal feed, humus, and artificially compounded feed, so they are very easy to farm.
2. Approximately how much does Australian lobster cost per jin?
The market price of Australian lobster is very expensive, generally around 250-350 yuan per jin, but due to differences in market, place of origin and selling time, the price will vary to some extent. For example, at the Xinfadi Agricultural Products Wholesale Market in Fengtai District, Beijing, the price is about 260 yuan per jin; at the Beiyuanchun Wholesale Market in Urumqi, Xinjiang, the price is about 350 yuan per jin; if purchased in a hotel, the price is about 600-1000 yuan per jin; if purchased in a supermarket, the market price is about 400 yuan per jin; if purchased wholesale at the market, the market price is about 200-400 yuan per jin. Therefore, the specific price still needs to be checked at the local market.
3. What are the farming techniques for Australian lobster?
1. Site selection and construction: where is it suitable to grow?
Australian lobsters like to grow in places with clear water quality, no surrounding pollution, and slightly sloped terrain. Therefore, you can build a cement pond with a length-to-width ratio of 1:3, a size of 2000 sq m, and a height of 3 m. Then build a shade shed over the pond, place some old tires, broken tiles, and 10 cm of silt on one side of the pond, and dig a drainage ditch to ensure that the terrain has a certain slope, which is conducive to regulating water quality and disease prevention and control. Finally, put 70 cm of water in the pond, place some aquatic plants and a small-power aerator, and surround it with plastic netting.
2. Shrimp fry stocking: how many should be stocked per mu of land?
From early April to early June, you can go to the market to select some shrimp fry with a smooth and bright appearance, no damage, and healthy physique, and put them into the pond. Generally, for shrimp fry with a body length of about 1.5 cm, it is best to stock 5000 fry per mu of land. If the pond is built in a greenhouse, stock 300 per sq m.
3. Feed feeding: when is the best time to feed?
Australian lobsters have omnivorous feeding habits. They eat cooked corn, wheat, soybeans, fish meal, river snails, earthworms, aquatic plants, and so on, so there is no need to worry about food. When feeding, try to feed once each in the morning and in the evening every day, and each time feed 20% in the morning and 80% in the evening. After the shrimp fry grow up, increase the amount in a timely manner to prevent them from killing each other due to insufficient food. During the feeding period, constantly observe the shrimp's growth, water quality, temperature, and so on, so as to better manage the lobsters.
4. Farming management techniques: how to manage?
(1) Water quality requirements: Australian lobsters have high requirements for water quality, which generally must be clear, high in oxygen content, and pollution-free. Therefore, change the water once every half month, and every 15 days sprinkle about 20 g of quicklime into the pond for disinfection to regulate water quality.
(2) Check the growth situation at any time: every morning, walk around the pond to see whether there is bait. If there is, adjust that day's bait, and observe the lobster's growth situation. If there are changes, take timely countermeasures.
(3) Check the water temperature at any time: at noon every day, measure the water temperature and observe the changes in the water. If the temperature is not enough, take measures to remedy it.
(4) Rodent and disease prevention and control: during the farming of Australian lobsters, there will be rats, centipedes, red worms, and so on, so promptly eliminate rats and surround the area with protective netting to prevent the invasion of rats, centipedes, and the like. For shrimp that have already died, promptly remove them to prevent live shrimp from eating them and causing disease.
The above is a detailed introduction to the market price and farming techniques of Australian lobster. We hope it is helpful to everyone.
