Pond renovation
Eradicate the weeds around the pond, remove excess silt at the bottom of the pond, level the bottom of the pond, reinforce the pool, block the loopholes, dredge into the drain, and inspect the electrical and mechanical equipment such as distribution lines, bait feeders, aerators, and pumps.
Pond disinfection
Let the bottom of the pool freeze in the winter and disinfect it with quicklime or bleaching pond. The dosage is 75kg/mu -100kg/mu and 5kg/mu, respectively. The method is to splash the whole pond with water, so as to kill pathogens. Wild fish. Usually, the quick disinfecting effect of quicklime is better. It not only can adjust the pH value, but also can improve the effect of the bottom material. It can create a good growth environment for the growth of fish, and it can also increase the calcium ion content in the culture water to meet the growth of fish. Quality needs. Maintain an excellent water quality environment.
Fertilizer fertilizer
After the disinfectant drug property disappears, the base fertilizer is injected 7 days to 10 days before the release of the seedlings, and the organic manure produced by mixing animal manure (preferably chicken manure), quicklime and phosphate fertilizer is applied to the bottom of the pool. The dosage is 200kg/mu -300kg/mu, and then the water is injected into the pond to 0.8m - 1.0m (The inlet should be set with 30 mesh sieve to prevent the wild fish and fish eggs from entering) to cultivate plankton The organisms, a week later, can see large amounts of plankton in the pond's body of water. After 3 days to 4 days, EM fungus and unicellular algal activin were applied to enhance the effect of water and water purification.
Fish selection
Fish stocks should be selected based on factors such as pond conditions, feed sources, farmers' technology, and local market needs. In short, based on the actual situation, it is necessary to determine the mode of stocking and reasonably mix stocking species in order to achieve higher aquaculture production and better aquaculture efficiency.
Fish quality
Fish of the same age should have neat specifications, strong physique, plump muscles, bright color, complete scales and fins, no injuries, no sickness, lively swimming and strong back-watering ability; At first, it seems that only the tail is not visible; the fish tail is not bent after leaving the water; the mouth and lid do not open, and the beating ceases; the fish body surface and the silk have no parasites, and the fish body surface and scales are intact. no damage.
Restocking mode
Adhere to highlight the principle of main breeding and scientific breeding. The general main fish culture accounts for 70%-80%, and fish rearing accounts for 20%-30%. When the main fish culture is determined, the fish is mixed with the mixed fish species according to the actual situation. Make full use of plankton and other natural baits in aquaculture waters to increase aquaculture production per unit area and increase aquaculture efficiency. Therefore, the matching fish species should be determined by the main species of fish, usually filter-feeding carp is used as a mixed-cultivation object, while oysters, oysters, and grass carp are the second-selected species, and the rest of the matched fish species should be treated as the main-cultivation. Fish may vary in size, fish with similar or identical food habits should be as few as possible with polyculture or not with polyculture. It is necessary to increase the stocking ratio of large-scale fish species as far as possible so as to reach the commodity specifications as soon as possible, mention the sales in the morning, reduce the density of fish ponds, and increase the breeding efficiency.
Fish disinfection
Curcumin is a yellow pigment extracted from the rhizome of turmeric. Curcumin has long been used in food industry as a Natural Pigment. It is stable to reducing agents, has strong coloring power and does not fade easily, but is sensitive to light, heat and iron ions. Mainly used for dyeing canned, intestinal products and sauces. Curcumin also has important economic value and a wide range of pharmacological effects, such as hypolipidemic, anti-oxidation, anti-inflammation, anti-atherosclerosis and so on.
