Fish breeding high yield technology
In order to better tap the potential of pond cultivation, increase the yield, increase economic efficiency. From April 2005 to the end of February 2006, an average mu yield of 3,700 kg and a profit of 12,000 yuan were obtained in a 36-mu aquaculture pond. Obtained the ideal result, now introduces its high-yielding aquaculture technology as follows:
First, change the original pond into two ponds. Please use a loader to shovel mud from the bottom of the pond. Deepen the pond to increase the water storage capacity so that the water depth can reach an average of 1.8 meters. Rebuilt 60 cm 80 cm three-dimensional light ditch more than 500 meters, divert water directly to the fish pond, surrounded by a mesh fence to isolate theft.
Second, the pool hardware facilities supporting the configuration of a set of 3kW power generation group, 6 aerators, three automatic feeders.
三ã€Preparatory work before stocking
1. Virus poisoning 15d-20d before laying seedlings, drain the pool water, sprinkling the ground with 80g-100g quick lime per square meter, and then enter the water 20cm-30cm, turn the bottom mud with a rake, after thorough disinfection can enter Shui Fei Tang.
2, water quality training After 7d-8d water quality culture, pool water transparency in the 20cm-30cm, the water was yellow-green or yellow-brown, indicating that the pond has been rich in basic bait, can be put on seedlings.
Fourth, the release of fry
On April 8, 2005, 3.2 million fish were released, and 45,000 tilapia heads were released a week later. At the beginning of May, 2400 florets with a specification of 0.1 kg/tail were released.
V. Daily management
24h was on duty management, often patrol pond. Check whether there is any clogging in the drainage and drainage products, remove obstructions in time, and ensure the smooth flow of water. Check whether there is residual bait, in order to adjust the amount of feeding on the day, whether there is no oxygen deficiency in the evening or night, and timely start the oxygen-increasing equipment. Check for diseased fish and dead fish, remove diseased fish and dead fish in time, and take measures for symptomatic control.
Feeding adheres to the principle of “four rulesâ€, that is, timing, quality (guarantee of feed quality, careful and detailed allocation of feed), and quantitative (quantitative value per pond, but according to the fish’s eating and feeding conditions, the amount of feeding should be adjusted appropriately. In order to avoid wasting feed, polluting the water), positioning (the location of each feeding is not changed).
Sixth, the sale of fish species According to the breeding situation, round-fishing, large-scale species of fish sold in time to maintain a reasonable density of fish ponds.
VII. Production of Feed and Feed The production of feed is provided by the self-made formula, and the feed mill takes it on behalf of the feed. The feed protein is 32%. According to the weather and the time the fish eats, the amount fed is 3%-5% of fish's body weight. Feeder feeders were used for feeding.
VIII. Disease Prevention and Control Fish disease prevention and control is based on the principle of “prevention as the main, comprehensive preventionâ€. During the entire culture period, water bodies should be disinfected periodically. Disinfection should be conducted 30 days after seedlings are planted, and once every 15 days and then after 20 days, disinfectants have bromine. Chlorohexaine, dibromohydantoin, chlorine dioxide, potassium permanganate, etc., as well as regular feeding baits, and vitamin c vitamin e and so on.
Nine, benefit analysis
1. 33,000 yuan/year of fish ponds, 6,000 yuan for fry, 25,000 yuan for depreciation of fixed assets, 200 tons of feed, 2,850 yuan/ton for feed, 570,000 yuan in total, 35,000 yuan for personnel salaries, and 30,000 yuan for other personnel. A total of 699,000 yuan was invested.
2. There were 44 tons sold in production, the average selling price of grass carp was 9.5 yuan/kg, and the average carp was 7.5 yuan/kg, totaling 378,000 yuan. The existing pond is 90t-100t and its specification is 1kg/tail of grass carp, 1.5kg/tail of carp and 0.5-0.5kg/tail of silver carp. Calculated according to 95t, according to 8 yuan / kg, total 760,000 yuan. A total of 1.138 million yuan.
3, profits to achieve a total profit of 439,000 yuan, 1 mu profit of 12,000 yuan.
X. Summary Achieving high and stable production of fingerlings in ponds. According to the farming situation, there are four points: First, adequate water supply; second, reasonable feed formulation; third, scientific management; and fourth, complete hardware facilities.
