The culture of lobsters in ponds is easy to feed and manage, the source of feed is wide, and the yield is high. The average yield per mu is around 3500-5500 yuan, but the following farming techniques need attention. The aquaculture facility pond area is suitable for 4-10 mu, with a depth of 1-1.5 meters and a slope ratio of 1:2.5. The bottom of the pool is flat, and the bottom soil is made of loam, and the slope is harder. The pond has good water retention and the water level is easy to regulate. Lobsters have a good ability to escape and they must do a good job in preventing escape facilities. Usually use plastic film or calcium plastic plate, along the pool around the use of bamboo piles or stakes support fenced escape. Before stocking, prepare shrimp seedlings 20-30 days before stocking, drain the pool water, remove excess silt, and renovate pool drains. Use 75 kg of quicklime per acre or bleaching powder, bleaching powder and other drugs to completely clear the pond for disinfection. Per-mu application of fermented livestock manure 500-600 kilograms, cultivating rotifers and Cladocera, copepod plankton, shrimp shrimp seedlings provide a suitable food. In the pond, aquatic plants such as Hydrilla verticillata, Malay's Okra, and Elodea are planted. The area of ​​aquatic plants accounts for 2/3 of shrimp pond area. At the same time, set up nets, or set up bamboo tubes, plastic tubes, etc., to provide lobsters with habitat, shelling and shelter. Shrimp seedlings can be reared in various breeding modes. The first is the summer stocking mode. The first batch of juvenile shrimps hatched in the year of stocking was mainly stocked, and the stocking time was in mid-late July. The juvenile shrimps had a size of 0.8 cm or more. 3-40000 fish rearing per acre. The second is the autumn stocking mode. The large size shrimp or shrimp species cultivated in the year of stocking were the main species, and the stocking time was from mid-August to September. The specifications of shrimps are 1.2 centimeters in size, 2.5-3 million fishes per acre, 2.5-3 centimeters shrimps, and 1.5-2 million fishes per acre. At the end of the year, a small part of the market can reach the market specifications. Most of them will be listed on the market from June to July in the following year. The commercial shrimp will weigh 25 grams and produce 300-500 kilograms per mu. The third is the winter and spring stocking mode. It is generally stocked in December or March-April. In the year of stocking, shrimps that do not meet the marketing specifications are mainly based on the specifications of 100-200 eggs per kilogram, and stocking of 1.5-2 million fishes per acre. After winter and spring breeding, it will be listed on the market from June to July. The commodity shrimp can weigh up to 30 grams and produce 400-500 kilograms per mu. Shrimp seedlings require regular specifications, with juvenile shrimps having a size of 0.8 cm or more and shrimps having a size of about 3 cm. The specifications of the shrimps stocked in the same pond should be the same, and should be enough at a time. Must be physically strong, with full appendages, no disease, no injuries, and strong vitality. Shrimp seedlings should be cultivated artificially. If it is a wild shrimp species, it should be domesticated after a period of time and then stocked, so as not to fight each other. It is worth noting that the winter restocking is carried out on a sunny morning, and summer and autumn retreats are conducted on sunny days in the morning or on rainy days to avoid sun exposure. Shrimp were bathed with 3%-5% saline before bathing for 10 minutes to kill parasites and pathogens. Shrimp species purchased from foreign countries should be treated slightly before they are stocked due to long periods of time away from the water. Shrimp seeds soaked in the pool for 1 minute, put it aside for 2-3 minutes, and then soaked for 1 minute, so repeated 2-3 times, so that the shrimp body surface and suck cavity water after the sucking enough to raise the survival rate. The lobster ponds are properly mixed with some squid to improve the water quality and make full use of the feed resources. The scientific feeding of lobsters is omnivorous and bulimia. For feed feeding, we must grasp the following three points: First, according to the nutritional needs of the lobster at the same stage of development, do a good job of feed combination and feeding. Lobster young shrimp, larva stage, with rotifers, Cladocera, copepods and aquatic insects larvae, etc., shrimp stage is to eat animal feed, plant feed. After the shrimp and shrimp species are stocked, they must timely apply fertilizer and fertilize water quality. In the fast-growing stage of lobsters in August-October, feed more bran, bean cake, and green feed to feed animal feed. From November to December, the lobsters were mainly fed with animal feed before winter. The second is feeding according to the lobster's habits and feeding characteristics. Lobsters are more likely to feed at night and have food and gluttony habits. Feed feeds must adhere to feeds once a day in the morning and in the afternoon, mainly in the afternoon, accounting for 70% of the total feeding amount; adopt qualitative, quantitative, timed feeding methods, feed enough feed, ensure that each shrimp is fed Eat enough to avoid competing for food. The third is based on the weather, changes in water quality and shrimp feeding activities reasonable feeding. The suitable water temperature for lobster growth is 20-32°C. In August-October, the lobster has a large amount of food intake, daily feeding amount can be arranged according to 6%-10% of the pool shrimp weight, and dry feed or compound feed can be arranged by 2%-4% according to the weather, water quality and shrimp activity. Foraging conditions increase or decrease. Continuous rainy weather or excessive water quality, can be fed less, when the weather is fine, more appropriate feeding; a large number of shrimp shelling less feeding, after shelling and more feeding; shrimp less feeding season, when normal growth more feeding . It is necessary to allow shrimp to eat well, but also to reduce waste and improve feed utilization. Daily management establishes a patrol pool inspection system, patrols the pool on a daily basis, and takes countermeasures in case of abnormalities. Control water quality, keep the amount of dissolved oxygen in shrimp ponds above 5 g/l, pH 7-8.5, and transparency about 40 cm. Change the water every 15-20 days, change the water every time by 1/3. Sprinkle lime water every 20 days and use 10 kg of lime per acre. Keep the water level stable and do not flicker. Strengthen the management of habitats and shelling sites, and keep more aquatic plants in the shrimp ponds. When large quantities of shrimp are shelled, no interference is allowed. After shelling, high-quality palatable feed is added immediately to prevent mutual killing and promote growth. Intensive inspections in flood season, prevent shrimp escape, and do a good job in the prevention and treatment of enemy pests. The fishing and transportation of commercial shrimp can be concentrated in June-July and November-December, firstly caught by the ground cage net, hand-cutting net and other tools, and finally the dry pool can be captured. It is also possible to catch large, small, and perennial fish; commercial shrimp is usually shipped in foam plastic boxes, or it can be shipped in plastic bags or shipped in refrigerated trucks. Keep the shrimps moist during transport and do not squeeze them to increase the survival rate. The fish species that can be mixed with lobster include squid, squid, oysters, crab, and shrimp. Polyculture fish should not be cultured in polyculture ponds, and grass carp and carp that feed on aquatic plants should not be excessive.
