Breeder Wei Hongqing, male, 44, senior high school culture, Sanbao Village, Gubao Town, Gaochun County, Nanjing, engaged in crab breeding production in the township of Gu Bai Town, covering an area of ​​35 acres. At the beginning of 2007, 14880 deer crabs, 260 pounds of green saplings, and 80 pounds of white maggots were planted. In May, 800 carp seedlings were introduced, and the size was about 5cm/tail, and 28,000 jins of snails were fed in batches, and 800 jin of acre was given. Feed 25,000 jins of small miscellaneous fish, 1,000 jin of pellet feed, and 3,000 jin of feed for wheat, corn, soybean meal and other agricultural products. In the pond, planted Vallisneria, Elodea, and Hydrilla verticillata. At the end of the year, 13,000 adult crabs were caught, and the survival rate was 87%. The average size was 0.405 catties per catty, 5260 catties were produced, the average sale price was 58 yuan/catty, and the crab’s income was 336,200 yuan. Shrimp income 23,200 yuan (of which the previous quarter income of 13,000 yuan, the next quarter income of 10,200 yuan), carp income of 7,000 yuan, other fish income of 5,000 yuan, total income of 336,200 yuan, a total investment of 125,400 yuan, gross profit of 210,800 yuan, Mu Mao Lida 6022 yuan. In recent years, the whole river crab culture in the united area of ​​Cooper has maintained high aquaculture efficiency every year and has rich aquaculture experience. Through exchanges with the model household Wei Hongqing, I think that all the production and management measures in the breeding process are in place and worth learning. Among them, the following three aspects of concrete work are experienced: 1, in the purchase of crab seed is very particular about, careful and meticulous. In the past few years, he has purchased fresh crab seedlings as a good choice for locally grown quality seedlings. When buying, he chooses a high-quality nutrient accumulation, a healthy, strong, disease-free, non-disabled, bright-colored, and neatly-ordered high-quality crab. In place. 2. Pay attention to the construction of the pond's ecological environment. In the past year, 70 pounds of Vallisneria seeds had been sowed, water peanuts had been set around the pond, and Elodea had been transplanted on both sides of the ring. On April 1st, Putianhuan was planted with leafy black algae, separated by 1.5 m, and the young grass was 810 cm high. 20 pounds, 15 pounds/mu of calcium superphosphate, 10 pounds/acre of urea at the beginning of May, and dismantled the net ring in June, and the water grass coverage rate reached 70% in the high-temperature season ponds. 1:1. On March 1st, 15,000 jin of big snail was released, and on May 10, 6,000 jin of snail was released. In August, 8,000 jin of snails were placed in two batches, and the snails were put into use. Through the above measures, the water body of the pond itself was further improved. The purification capacity further improved the pond's breeding ecological environment and the ecological balance was in a virtuous circle. 3, prevention and treatment of disease measures are effective. In December 2006, the pond was dredged and exposed to sunlight. In January 2007, Quantang disinfected with 7,000 kg of quick lime. During the first three rounds of crab shelling in the breeding process, an insecticidal disinfecting operation was conducted after each end. About 10 days in the summer, it is necessary to use a modified base and microecological preparations at regular intervals. The above prevention and control measures are conducive to achieving the efficacy of killing pathogens and improving the sediment quality of the pond and optimizing the soil structure. The prevention is the main method, the prevention is more important than the treatment, and the prevention and treatment of the disease is effective.
