1, breeding conditions: in the less silt, water supply, sufficient dissolved oxygen, easy to drain the place to build a pond, and do a good job of disinfection, and build a good pond fish house, feed warehouse, feeding canopy, and so on.
2, fry placement: choose a robust, well-proportioned fry placement, after the "water test" before the release of seedlings.
3, feed feeding: feeding high-protein feed, generally using conventional methods to raise grass carp to more than 2 pounds, and then transferred to the drift pool for three consecutive months to feed broad beans.
4, daily management: carefully patrol the pond, keep the water quality fresh, and do a good job of fish disease prevention and treatment.
First, breeding conditions
Crisp Anhui fish farming should generally be less silt, water, fresh water, dissolved oxygen, easy to drain the place to build a pond, must be stocked with quicklime or bleach on the pond disinfection treatment. In addition, it is necessary to build a good pond fish house, feed storage, feeding canopy table.
Second, the fish fry put
Selection of robust, well-proportioned, disease-free fry put, the number should be moderate, not too dense. After? The water test? After that, then put the fry.
Third, feed feeding
1, in the process of crunching should be fed with high-protein plants, it is best to grind fava beans into powder feeding, but also to feed some of the green material, so that it feeds itself. Feeding broad beans need to be soaked and germinated, after rinsing clean and odorless before feeding. Generally, the grass carp is raised to more than 2 pounds by conventional methods, and then transferred to the drift pool for 3 consecutive months to feed broad beans to the fish to make them brittle.
2, the daily feeding amount of 3% -5% of the weight of the fish, in the baiting process, should follow the ? Four fixed?
Four, daily management
1, to maintain the breeding of fish pond water depth of 2.5 meters, the transparency of the pond water should be maintained at 25-30cm, depending on the water quality of the appropriate amount of sets of water change. Do a good job of fish disease prevention and treatment, generally available 0.8mg / l of copper sulfate, ferrous sulfate (5:2) combination of the whole pool sprinkled, or trichloroisocyanuric acid 0.4mg / l or chlorine dioxide 0.2mg / l, once a month, the above drugs are used alternately.
2, frequent pond inspections, check whether the water inlet and outlet is perfect, there are no loopholes, to observe whether the fish activity is normal, as well as growth and water quality changes. From time to time, the weight of the fish body can be tested by sampling, so as to estimate the total weight of the fish, so as to grasp the amount of bait. The fish pond should be strictly guarded to prevent theft and burglary, and reduce the impact of human factors on the project test.
