Paddy field cultivation of ornamental fish

<

Rice field fish farming: According to the rice-fish symbiosis theory, the planting and breeding industries are skillfully combined in paddy fields to achieve the purpose of raising fish in rice, increasing rice production, and harvesting fish. There are several varieties of ornamental fish in paddy fields:
1. Red peony root and red lotus root have dual values ​​of food and ornamental. Its characteristic is that the body size of red dragonfly is similar to that of high-type heterotrophic silver crucian carp, and it is red and bright in color.
2. Red lotus root, orange color, in addition to the chest was pale white, without any noise, short and high body, back and wide, thick, short head and tail, the shape of "purse."
3. All of them have the same common features. They are highly adaptable and able to tolerate hypoxia. The water temperature can be ingested at about 10°C to 32°C, and the water at pH 6.5 to 8.5 can also grow and multiply. From April to July in the reproductive season, eggs are sticky and produced in batches, and they are extremely attractive in gold fish tanks.

First, select good paddy fields to choose ventilation, water sources sufficient and non-polluting, water quality in line with fishery water standards, energy irrigation, drought, dry rain, flooding, soil is loam or clay, water, fertilizer retention performance, field area In 1 mu ~ 5 acres is appropriate.

Second, rice field project
1. Heightening and strengthening of field ridges: Field ridges reinforced before transplanting are generally 50 centimeters high and 40 centimeters wide (depending on the need for flooding). They are strong and effective.
2. Excavation and fishery slip: The fishery slip covers about 5% of the total area. It can be built on the edge of the inlet or at the field corner. It is excavated into a rectangle with a depth of 80 cm. It is connected with the fishing ditch, and is caught in the fishing slip 1/3. Shade, to benefit from high temperatures in the summer to avoid the shade cooling.
3. Excavation of fish ditch: After planting seedlings and turning green, excavation is carried out according to the size and shape of the plots, and excavation trenches are excavated in the form of “field” or “well”. The depth and width of the fishing ditch are each 30 cm. ~40 cm.
4. Make a note, drain outlet, install the barrage. Corresponding to the inlet and outlet, the barrage net is made of wood piles with metal nets or polyethylene nets and other dense mesh materials. The height should be 20 cm higher than the field ridge, and it should be installed and fixed in a curved shape with the convex surface facing the water flow. If there are many debris, or set up a double barrage, the fish will be trapped inside and the outer layer will be blocked.

三、Preparatory work before stocking
1. After 15 days of stocking, 10 kg to 15 kg of lime water per acre is used to clean the fish ditch and fish, and 50 kg of rot manure is applied to cultivate natural plankton such as plankton and rice paddies The water must be filtered through sieve nets to prevent wild fish from entering.
2. After restocking, strengthen management, and sooner or later must inspect the fields, apply water and fertilize as appropriate, and apply 10 kg to 20 kg of fermented pig cow dung every week. If necessary, feed some bean cake, bran and other fine ingredients.
3. The amount of stocking should be increased or decreased according to the specific conditions such as paddy field conditions, the amount of bait fertilizer, and management level. Use 3% to 4% saline solution for dipping and sterilizing the seed each time.

Four, rice field cultivation seed three-level seedlings
1. Early and mid-season rice transplants are mostly planted in the beginning of summer and small full season. The newly hatched fry can be cultivated into summer flowers. The stocking rate per acre is approximately 20 days from the spawning of red earthworms and red lotuses to early and medium rice transplants. There are 25,000 Hung Hom and 35,000 red purse. Cultivate 20 days to develop 1-inch summer fish species, you can field farming.
2. Mong species fish summer solstice, disease prevention measures to keep up. The first division is generally in mid-May, such as seedlings turn green after each acre should be put 1 inch summer fish species 10000 ~ 15,000 tail, after about 50 days of cultivation. Generally can grow to more than 2 inches.
3. The summer heat and the summer heat rise, and the feeding and management should be serious. The second subculture will be carried out and transferred to the middle paddy field. There should be 5000 to 8,000 tails per acre. After 60 days of cultivation up to 3 inches to 4 inches, can be marketed as aquarium fish.
4. The temperature of the autumn dew equinox is reduced, and careful management improves production. The unsold fish species were reared to the late rice field for the third time, with about 3,000 tails per acre. This way, they have been reared until the late rice is harvested to cultivate large-scale ornamental fish species and food fish.

V. Cultivating fish species Rice field management
1. Fish farming Rice paddy fields have less pests and diseases, and often do not need to fight pesticides. If individual pests and diseases meet the prevention and control targets, pesticides can be sprayed on paddy fields. Usually, they are selected for their low toxicity, convenient use, high efficiency, low toxicity, and low residue. When pesticides are applied, they must strictly control the capacity of the pesticides, deepen the field water, or apply pesticides while entering and leaving the water. Take a rice field twice and apply half at a time to allow the fish to leave automatically. Powdered pesticides were applied when the dew had not yet dried in the morning, and milk (oil) pesticides were sprayed in the evening. When the spray was applied, the sprinklers turned upward and swept across the rice stems and leaves. If the phenomenon of poisoning of dead fish is found, the pesticide application should be stopped immediately and new remedies should be taken in time by adding new water.
2. Fishery rice fields should pay attention to the use of chemical fertilizers: based on the main fertilizer, chase fertilizer can take a small number of times, block and deep application and other methods, the general application of urea 5 kg, 4 kg of superphosphate safe dosage .
3. In order to ensure the safety of fish, the fish can be concentrated in a wide ditch or in a fishery during the application of fertilizer. When the toxicity disappears, the fish can be returned to the rice field.
4. Frequently dredge the fish ditch, overhaul the fishing grate, add new water in the hot season, remove and bury the dead fish, and record the water temperature, food intake, dissolved oxygen, survival rate and disease conditions.

Sixth, prevent disease and eliminate pests to drive away and destroy the enemy of fish, such as water birds, voles, otters, squid, water snakes, otters and so on. Grass ash can be used to kill the green mud moss and water net algae. Each month, 10 kilograms of calcareous pulp is spilled every acre to prevent fish diseases and rice pests and diseases. Fish farming rice fields are regularly filled with fresh water to regulate water quality. No chickens, ducks, geese, etc. are allowed to enter.

VII. Harvest After the harvest of the late-season rice, most red locusts and red pods grow into large-sized fish species, which can be sold in large quantities as ornamental fish. This fish is easy to raise, and it is very beautiful in the fishing tank and aquarium, so the price is high. At the same time, it can be sold as a species of fish to the various ponds for raising, to achieve product specifications for food sales, but also on the dinner.
