1. Pond conditions The area of â€‹â€‹ponds mixed with shrimps and shrimps is best managed between 5 and 6 acres. The pool depth is 1.2 to 1.5 meters and the water depth is 0.8 to 1.0 meters. The pond slope ratio is 1 to 3, and the ponds are firm. In order to prevent escaping and fleeing, we can use iron sheet or concrete tile to set off the escape wall. When the escape prevention wall is set, it is required to be buried 20cm underground and 30cm above the ground. There are a few cement tiles in the north side of the poolside block as a feed station. Set it along the side of the pond, half in the water and the Other half on the water. The pond requires easy injection and drainage, and the aquaculture water source should meet the national fishery water standards.
2. Preparation before stocking In addition to the new pond, the old pond must completely drain the pool water and remove more than 15cm of sludge, and then disinfect it with quick lime 100kg/mu dry pond. After clear pond 3 days after injection of 80cm water injection, 80 mesh filter shall be applied to the inlet to prevent the entry of harmful organisms into the shrimp pond. In order to supplement the biological feed of earthworms, live snails (100kg/mu) should be placed before stocking, allowing them to reproduce and grow.
3, kind of stocking
3.1 Stocking specifications and density Density of stocking is carried out according to the cultivation method of the year, and the stock size of stocking should be not less than 250g, so that when the food is stopped in autumn, about 0.6kg of high-quality goods can be listed. Stocking density is 150/mu.
3.2 Stocking time and method of stocking time East China and Central China are generally from mid-May to early June, South China is in early May. The water temperature of the pond at the time of stocking is required to be above 25Â°C, and the weather should be selected with good eyesight. The stocked quail species require uniform specifications, no disease or injury, and the oysters can be sterilized with 4% salt water for 10 minutes before stocking.
4. The species of stocks for shrimp stocking and stocking is best local Qinghe shrimp which is produced by the local people. The specification of shrimp species requires 1.5cm or more, and the stocking quantity is 60,000 tail/mu. Restocking time in early July, shrimp species can be deepened after pooling to 1m.
5. Routine management The daily management is mainly based on shrimp, and the shrimp is fed with commodity shrimp according to the conventional feeding amount. After stocking, some fresh live fish such as small ragfish and pig liver can be put in stocking. After one month, they can gradually stop feeding. Afterwards, they use bait shrimp and breeding snails as baits. During the breeding period, lime was properly applied to maintain the pH of the pool water between 7.0 and 7.5. Appropriate exchange of new water, changing the amount of water is generally 1/5 of the original pool of water. Take a daily tour of the pond, observe the activities of the shrimps and cockroaches in the pool, check the barriers in and out of the water outlets, and the changes in water quality. The patrol pond should make records and discover problems and deal with them in time.
6, fishing and temporary shrimp farming can be based on market conditions and growth specifications to take the combination of catching and centralized fishing, while the catch is to wait for the catch of shrimp after the dry pool catch. Due to the concentration of earthworms, if they can not be sold off once, they can be raised temporarily. The ground can be covered with 25cm thick moist sand at home or in the warehouse, and can be buried in the sand, usually at room temperature 15 When stored around Â°C for more than 30 days, during the period according to the market conditions at that time gradually listed on the market.
Introduction of New Bucket Elevator:
The New Bucket Elevator is a new type developed model compare with Dty Bucket Elevator.
Its design similar with Japanese Satake Type, with lot of advantages. it is widely used for continuous vertical lifting for granular materials, such as wheat, maize, sesame, kidney beans, chia seed, quinoa seed etc. It extensively applies for the lifting of bulk stocks in feeding stuff plant, flour mill, and grain depot of different scale.
Advantages of New Bucket Elevator:1. High-efficiency
2.Very Low breakage
3.Mobility and Flexibility
4.10 tons/h available
