Rice paddy field key technologies

Loach is a kind of aquatic animal with delicious taste, high nutritional value and strong adaptability, which is quite popular among consumers. Muddy aquaculture has gradually emerged, but the use of paddy fields for breeding mud loach is rare. This article gives an introduction to the main technical measures for the breeding of loach in paddy fields for farmers' reference.

1. The choice of rice fields

We should select paddy fields with good water source conditions, loose and fertile soil, strong water retention and fertilizer retention, and easy management. At the same time, it is necessary to increase the height of the field ridges. Before the locust seedlings are stocked, sufficient organic fertilizer should be applied, and the rice fields should be fully sterilized with quicklime.

2. Choose a good seed

Variety has a direct impact on production. Therefore, we should choose to have fast-growing, strong fertility, disease-resistant loach seed.

3. Stocking time and density

After paddy field transplanting, it can be stocked with 10 kg of muddy broodstock per acre, and can produce about 75 kg of mud per acre without feeding. It should be noted that it is not appropriate to breed other fish at the same time in farmed, muddy rice fields.

4. Field management

In order to control the paddy fields with muddy rice, special personnel should be responsible for the management, and high-efficiency and low-toxicity pesticides should be used for pest control of rice, which can be applied according to the conventional dosage. It should be done by spraying deep water and spraying upwards when spraying pesticides. Since muddy loaches inhabit mud, in general, it is much safer to use pesticides and chemical fertilizers in the paddy fields where the cultivation is carried out than in paddy fields. However, the use of toxaphene, carbofuran, quick lime, and tea cakes must be prohibited. During the hot season, the field is properly filled with deep water to adjust the temperature of the water to prevent the mud from burning. In peacetime, it is necessary to constantly check the rehabilitation of fishing facilities and timely blocking of loopholes to prevent poultry from eating mud in the fields.

5. Fry hatching

Muddy breeding season is generally between April and September each year. In the early days, eggs are spawned in the early morning on sunny days, and eggs are laid in the late afternoon or early evening. The eggs are small and transparent and sticky.

Before the oviposition estrus occurs, a certain amount of brown pieces, willow roots or aquatic plants should be timely inserted into the rice paddies to facilitate the adhesion of muddy eggs. After the oviposition is basically completed, it is best to collect the fish nests with muddy eggs. In the fish pond in Tianjiao, let it hatch. This will reduce the harm of predators in the field and help increase the hatching rate.

6. Harvest method

Mudworms are difficult to catch because they live in mud. However, depending on the characteristics of the muddy habits in different seasons, the following methods can be used for harvesting: In winter, several piles of pigs and cow dung are piled up in the deeper layers of the mud in the field to induce the muddy to be concentrated in the dung heap for multiple fishing; In spring, the water inlet and outlet are opened, and bamboo rafts are installed. The loach will naturally enter with water; in autumn, all the water in the fields will be drained and re-sunshine, and the surface will be covered with a thin layer of water until the loach has been removed from the mud. After it came out, it was arrested.
