2. Waterproof plastic sheets are laid on the bottom of the pond, covering an area of 6670m2, with a unit price of 2 yuan /m2 and a cost of * * *13,340 yuan;
3. At least one intake gate and one drainage gate, and three sluice slots: outer (coarse screen), middle (gate) and inner (conical screen), at a cost of 1200 yuan;
The cost is * * * 14540 yuan.
(2) Configuration of hardware facilities: water pump, water inlet and drainage pipeline, aerator and cable.
1, diesel engine+water pump: 6000 yuan;
2. Water inlet and drainage pipeline: 200 yuan;
3. Water-wheel aerator (Fudi, Zhejiang): 1900 yuan/1.5kw, each set can accommodate 5-7 mu of high-density intensive shrimp ponds, with 2 sets for 3,800 yuan;
4. Cable: 1000 Yuan.
The cost is * * * yuan 1 1000.
(3), clear pond: substrate improver
20-30 days before sowing, the water is 20-30cm, and the whole pool is sprinkled with 50ppm of quicklime 1-2kg/m3 or bleaching powder (25-32% of available chlorine), and it is drained after 2 days, and the water is 60-80cm with 80- 100 mesh. Consumption of quicklime is 2668kg, and the price is 200 yuan/ton, * * * in 600 yuan.
(4) Fertilizer: chicken manure, inorganic fertilizer and biological bait.
Fertilize immediately after entering the water, according to the nitrogen-phosphorus ratio of 5:1,apply nitrogen fertilizer 1-2kg per mu, and then apply fertilizer every 2-3 days, and the dosage is 1/2; Chicken manure was fermented with quicklime and hung on the wall of the pond by sling method to prolong the fertilizer efficiency. Fermented chicken manure can be applied to the new shrimp pond at the rate of 0/5-20kg (dry weight) per mu/kloc. After 7- 10 days of culture, the transparency is 30-50cm, and the seedlings can be put in brown, tan or green. Consumption of nitrogen fertilizer 50kg, this * * * 500 yuan.
(5) Shrimp seedlings
Pollution-free shrimps should not exceed 180 yuan/10,000, and put10,000 per mu, with a cost of * * *18,000 yuan.
(6) Drugs for production: conventional disinfection drugs, water (bottom) improvers and microecological agents.
1, routine disinfection: 10- 15 days/time bleaching powder 1-2ppmpV iodine 1ppm, etc.
2. Water quality protection agent: 15 days/time zeolite powder, bentonite and medical stone powder (80- 120 mesh), 20-30kg/ mu; Dolomite 15-20ppm
3. Live bacteria preparation: such as Shuihubao 1- 1.5kg/ mu/15 days, the cost is about 3,000 yuan.
(7) Bait: compound feed, fresh fish and shellfish.
1, according to the feed coefficient of compound bait 1.2, the finished shrimp can be produced 10T (see "II, Benefit" for analysis), and the consumption of compound feed 12T is about 5000 yuan /T, and the cost is 60000 yuan. This is the estimated value of this cost, and a large number of fresh bait will be fed in the middle and late stage of breeding to save costs and improve the growth rate of shrimp.
2, fresh bait need disinfection before feeding. The cost is about 60000 yuan.
(8) Energy consumption
1, aerator: the seedlings will not be turned on for half a month; Disconnected at night from half a month to January, fully opened at night after January, disconnected during the day, and stopped when feeding 1-2h. The total power is 3kw, the breeding period is about 4 months, the startup time is 1500 hours, the cumulative power consumption is 4,500 kWh, the unit price is 0.6 yuan/kWh, and the electricity fee is 2,700 yuan;
2. Water pump: diesel engine uses diesel oil 1 barrel, and the cost is 8 180= 1440 yuan. The total cost is 4000 yuan.
(9) Labor: technicians and short-term workers.
1, * * * There are 3 technicians, who can manage at least 60 mu of shrimp ponds, and each person's annual salary is 20,000 yuan. 10 mu shall share the salary of technicians 10000 yuan;
2. In order to timely and professionally complete the installation and renovation of hardware facilities, the finished prawns leaving the pond, etc., it is necessary to hire local short-term workers to help, which can be calculated as 60 yuan/person/day, and 1200 yuan should be enough. This fee is * * * calculated as 1 1200 yuan.
(X) Others: shrimp nets and ropes, etc.
* * * Yuan 1000.
According to the above budget, it will cost * * * RMB 123840 yuan to complete the culture cycle of Penaeus vannamei every ten mu.
Second, the benefits
* * * Seeding1100,000, survival rate is 50%, and the specification of finished shrimp is 70-80 /kg. From this calculation, 6.7T of finished shrimp can be produced, and the purchase price should not be lower than 25 yuan /kg, and the sales income167,000 yuan.
Third, profits
To sum up, the net profit can be 43 160 yuan if the intensive culture of Penaeus vannamei per 10 mu is completed in the first year.
