Technique of duck-fish-rice farming combined

Many households in the regions, especially the Mekong River Delta, have experience in raising ducks in combination with stocking fish in rice fields, bringing benefits to diversify products in rice fields, increasing crops, reducing chemical fertilizers due to compensation. with duck manure source. Ducks and fish also eat insect and pestilent insects, which have increased economic efficiency, improved rice quality, etc.

Prepare rice fields

Fields must have strong banks, not landslides. High shore field, higher than the water level at the highest of 0.5m. The water level in the field is often 30-35cm. There are ditches around the field. The canal is 1-1.2m wide, 1 meter deep and has fish ponds equal to 7-8% of the field area for fish to live, keep fish, avoid sunshine for fish and harvest mature fish. It was time to harvest the fish to put fish, in the field, into this pond to catch.

On the surface of the pond, make a barn to trap ducks at night and do not release ducks into rice fields because of bad weather. Food spilled ducks, duck manure is fish feed. Clearing the bush in the field, killing snakes, snakehead fish, etc.

Fish farming

The depth of paddy rice fields is not susceptible to weather and sunlight. It is necessary to select fish that can tolerate heat, alum, accustomed to living and searching for prey in the bottom layer. 8cm, tilapia and hibiscus 3-5cm. One crop per year, stocking one crop of fish, the number of fish / m ² with fish such as hanks is about 30%, carp 30%, tilapia 40%. The type of heavy alum fields only stocked 30% tilapia, 50% deep-sea fish.

Breeding and dropping ducks

Laying ducklings :

Super meat duck breeds: 40-50 heads / 1,000m ² rice fields. Super egg duck breed: 60-70 heads / 1,000m ² rice fields. Coop 3-4 sheds / m ² floor.

Meat ducks :

The first week of duckling in a shelter. The second week of feeding the ducks to the floor. 20 heads / m ² in the first 4 weeks, 10-12 children / m ² 5-10 weeks old. Drop ducks to the field 60-80 heads / 1,000m ² .

Method of releasing ducks into rice fields:

In the first month, from the time of transplanting the rice is not released, but only to release the fish into the field.

After the first month, when the rice starts to bloom, then the root system grows firmly, then release the duck into the field. In the period of flowering, only grazing ducks in the part of the ponds and ditches surrounding the fields, in the field, only fish take advantage of the pollen source of falling rice and other microorganisms.

During the rice harvest period, release ducks into the field to take advantage of spilled paddy and other bait. After harvesting the rice, it will continue to keep fish for a while and then harvest the fish.
