The paddy field can raise loach, make full use of paddy field resources, can play a utilitarian role of killing two birds with one stone.

Starting rice loach farming. After mechanized cultivation, paddy fields should be fully fertilized with bottom fertilizer, preferably farmyard fertilizer, with less or no chemical fertilizer. Loach seedlings can be stocked in the paddy field after transplanting. The water inlet and outlet are equipped with a double-layer mesh fence to prevent leakage. The water depth can be about 10 centimeters shallow at the beginning when the rice seedlings grow taller, and the water level is 20-30 centimeters. The stocking density of rice field breeding loach. Loach seedlings with body length of about 3 cm should be stocked with 0.1-0.2 kg per square meter, i.e. 30-50 tails. About 20,000 to 25,000 loaches per mu. Selection and placement of bait for rice-farming loach. Loach are particularly fond of fish. If a single high-protein feed is fed for a week, it will cause loaches to aggregate in the paddy field, increase the number of intestinal respirations, and lead to a large number of loach deaths. Therefore, attention should be paid to the combination of high protein feed and fiber feed. Feeding. The water level should be controlled to regulate the water temperature to prevent the high temperature from harming the fish. Emphasize the prevention and treatment of diseases to ensure the survival rate. There are mainly parasitic diseases, water mold and bacterial diseases, the specific control methods can be found online.

Paddy loach bait feeding amount. The feeding amount is 2% of body weight when the water temperature is 15℃, and gradually increases to 10-15% with the rise of water temperature. The bait should be made into lumps or chunks of sticky bait and spread evenly in the paddy field. Breeding of loaches in paddy fields should be prevented from escaping. If there is fresh water flowing into the field, loaches will escape against the flow, so be careful to plug the leakage on rainy days. Yield of loach breeding in paddy fields. After feeding for 4 months, the adult loach can produce up to 500-800 grams per square meter, and the mu yield is about 300-450 kilograms. Rice-farmed crayfish and rice-farmed land ducks have formed a successful model and have been popularized to a certain extent. Previously, raising loach in paddy fields was once popular, but in the end, due to various reasons, the benefits are not good. Although it is still on the upswing, the scale is manageable.

In short, aquaculture of loaches in paddy fields is a new mode of culture. The current cultivation technology is very mature, suitable for rice-producing areas of farmers to increase production and income. Paddy loach farming is a high-investment, high-risk industry, be careful when entering the industry. It is best to go to the farming loach rice farmers on-site observation, and then decide whether to do.
