Goldfish are suitable for survival in shallow water. According to information, it is more beautiful to culture goldfish in small water bodies than to culture them in ponds. Paddy farming goldfish is an ecological breeding model, and the profit per mu is at least 3,000 yuan, which is easy to form. After years of trials in the Chaoyang Municipal Fisheries Institute and Aquatic Technology Promotion Station, the soil organic matter content in the cultivated layer of cultivated goldfish has increased, and goldfish in paddy fields are good projects for the development of high-efficiency agriculture.
1. The choice of rice fields
In 2001, 20 acres of paddy fields were selected for the Chaoyang Aquatic Products Breeding Ground. Among them, 4 acres of goldfish were bred into four pools with an area of ​​one acre each. 16 acres of rice were grown as control fields.
2. Paddy field construction
In the field project, a ditch with a depth of about 0.5 m and a width of about 1.0 m is dug around each rice pond with a slope ratio of 1:2.5 and the slope is tamped. There is a “Ten†ditch in the center of the paddy field, and the aquaculture ditch accounts for the area of ​​rice paddies. 15%.
Anti-escape facilities The ponds in the original rice fields shall be raised by 20-30 cm in height to ensure that the accidental accidents such as rainstorms cause the water to escape the fish, and at the same time use screens to prevent escape at the entrance and exit of rice fields.
3. Rice cultivation techniques
On June 10, rice was transplanted and the rice fields were planted with the same amount of basal fertilizer before transplanting. Application of ammonium bicarbonate 50 kg / mu, compound fertilizer 20 kg / mu. Selecting a rice with good traits, the rice harvesting period is approximately the same as the harvesting period of the fish, and the planting density on both sides of the ditch is appropriately increased.
4. Fish fry stocking
The paddy field was disinfected and water was injected 10 days before the seedlings were released, and 20 g/m3 of quicklime was used to sprinkle the fish ditch to kill germs and enemy pests.
The seedlings were planted and returned to their seedlings. After the rice seedlings were returned to green, they were brought back from Jinzhou on June 27 and returned to Jinzhou with good-looking, well-balanced goldfish seedlings (weights of 2-3 grams per tail). They were placed in paddy fields after malachite green disinfection. Flow gold blisters put 10,000 seedlings per acre, 9,000 pearls, 8250 red heads, and 7750 tails of ink.
5. Management
The feed was fed in the ring ditch to construct 2-4 bait stations, training the goldfish to eat, and selected squid species grain feed, crude protein was about 34%. Two shots per day, at 10 and 15 o'clock, daily feeds accounted for 4% to 5% of the fish's body weight, which took 1 hour to finish, and the bait station was cleaned daily.
Water quality management adjusts the depth of water according to the needs of rice fish. From transplanting to tillering, shallow irrigation is required to promote rooting and tillering, and rice is gradually increased in water level after the tillering till the growing season. In particular, fresh water or appropriate amount of water should be constantly added to maintain fresh water quality in summer. Water transparency is maintained at about 30-40 cm.
Rice disease prevention and treatment
Control of rice tsutsugamushi with 200ml/mu 18% insecticide water and 1125 kg of water spray once; control rice sheath blight, rice smut with synergistic jinggangmycin 250ml/mu water spray once; organophosphorus pesticides disabled , The general medication before the field surface water, up to 20 cm deep, timely change of water after spraying.
Fish disease prevention and control of gutters in the ring gully every 15 days, the amount of 10 kg / acre. Feed the bait once every 7 days. Helminthic disease was found on July 3, and treatment with 0.7*10 negative 6-point copper sulfate was effective.
Rice fertilization
Ammonium bicarbonate should not be used after the fry is released to prevent death from fish poisoning due to ammonia poisoning. Apply a small amount of fertilizer to the principle of applying fertilizer once a month, 4-5 kg/mu, and compound fertilizer 150 kg/mu. The fertilizer was withdrawn directly to Tanaka.
Day-to-day management will be conducted once in the morning and at night. Attention should be paid to observing the abnormalities of goldfish activities to prevent ducks, snakes, rats, frogs, and birds from entering the rice fields and preying on goldfish.
6. Harvest
On September 27, 2001, goldfish were caught and 300 kg of bait were fed to produce 33,000 goldfish. The average yield was 8,250 fish per mu and the survival rate was 94.3%.
On October 7, rice was harvested, and 4 acres of paddy fields that harvested goldfish harvested 2020 kg of rice, and 16 acres of paddy fields without goldfish harvested 7440 kg of rice.
