The drought tolerance of Australian freshwater lobster is second only to crab. It is convenient for long-distance transportation of live shrimp. If the transportation volume is large or the transportation distance is long, baskets and boxes made of wicker or bamboo or foam boxes with holes on all sides will be used for shipment. Wash the shrimps before transportation and clamp them with pliers. Each box can hold 10- 15kg. Put a small amount of aquatic plants on it and clamp the lid with wire. Sprinkle a small amount of clean fresh water on the way to keep the commercial shrimps in the box moist. Handle with care when transporting. When the temperature does not exceed 28℃, the transportation survival rate reaches 100% within 24 hours. After the commercial shrimps arrive, the freshwater lobsters should be dispersed in cement or ice bucket or cold storage tank at 8- 10℃ and soaked in water to keep moist. Do not concentrate a large number of lobsters in water containers to avoid suffocation and death due to excessive density.

A female Macrobrachium australis only lays eggs 3-4 times a year. In theory, the maximum number of seedlings hatched can reach 800, but in fact, there are only 200-300 seedlings, and finally only 100 seedlings are formed. In other words, thousands of females are needed to breed 6,543.8+0,000 seedlings. Rare things are more expensive. Generally speaking, the big seedlings with a body length of 3cm are around 2 yuan/Tail, and the price is relatively high. In addition to Jiangsu and Zhejiang, many places are raising seedlings. As far as I know, there are seedlings in Dongguan, Shantou, Qingyuan, Jiangmen, Zhuhai and other places in Guangdong, but the scale is small, so the price of seedlings is not cheap, but it has been in short supply.

At present, there are two main modes of freshwater crayfish culture in Australia. One is to breed Penaeus vannamei, with hundreds of prawns mixed per mu, and the breeding effect is very good; The other is to raise Australian green shrimps, with 2000 ~ 3000 seedlings per mu, and some silver carp and bighead carp in ordinary ponds, and the effect is also good. Australian blue lobster is more suitable for soil pond culture, but not for high-rise pond covered with plastic film or cement, because it grows slowly in cement pond. At present, there is no complete technical system or operating rules for farming operation, and now farmers basically rely on their own farming experience to raise.

In the breeding cycle, 2cm seedlings in the south can reach the commercial specifications (more than 75g/ tail) in 4 ~ 5 months, and the time in the north is longer. It is safe to bear the low temperature above 7℃. Now the data says that it is above 3℃, which is actually very dangerous. Its adaptive high temperature range is 36℃-38℃, but this temperature will affect its reproduction, and the female shrimp may give up hatching. The optimum breeding temperature should be 28℃ to 30℃. I think farming in the south may have more advantages than farming in the north.

If the survival rate of Australian blue lobster can reach 80%, it is an ideal state. In 20 13, the price of commercial shrimp was 30~40 yuan /500g, and this year it rose to 50~60 yuan /500g due to the overall price increase of Penaeus vannamei. According to the calculation of 3000 animals per mu, 75g/ animal can be raised. Ideally, if the yield per mu exceeds 200kg and the price is 50 yuan /500g, the output value per mu will reach more than 20,000 yuan. Its breeding cost is about 10~ 15 yuan /500g, of which seedlings account for about half of the breeding cost, and the profit is still considerable after eliminating the cost.
