Breeding loach can choose abandoned ponds or rice fields as breeding sites, and need to introduce pollution-free, nutrient-rich river or lake water into the pond during breeding, and can also provide fishmeal, rice bran and other food for loach, and at the same time, in the process of breeding, copper sulfate ferrous sulfate mixture needs to be regularly put into the loach fish to make the healthy growth of loach.

1. Breeding sites

Farming loach fish requires the selection of suitable premises. Loach fish can be cultivated using abandoned ponds, and at the same time, the water in the pond needs to be drained before breeding, and the well water and outlet in the pond are covered with barbed wire, and then sprinkled with quicklime into the pond for disinfection, and the loach can be farmed.

2. Aquaculture water source

When breeding loach fish, it is also necessary to choose the right water source, tap water contains chlorine, which is not suitable for breeding loaches, so it is best to use the breeding loach without being polluted. Trace elements are abundant in river or lake water, and after introducing water into the pond, it is necessary to fertilize the water to increase the amount of plankton in the water.

3. Suitable feed

When breeding loach fish, it can be provided with fly maggots, fish meal, rice bran and wheat bran, vegetable cakes and other feed, and when feeding, it is necessary to put the appropriate feed according to the season, generally in May and June, it can provide 4% of the total weight of the loach fish, and in July and August, it is necessary to provide 8% of the total weight of the feed.

4. Disease prevention

The accumulation of feces discharged by loaches in the pond will produce harmful gases, resulting in bubble disease in loaches, so in order to prevent loaches from becoming diseased, it is necessary to regularly use wooden sticks to stir the water at the bottom of the pond to discharge harmful gases, and at the same time, copper sulfate ferrous sulfate mixture can be poured into the pond to make loach fish grow healthily.

<>1. Preparation for breeding: The depth of the pond is between, the pH value of the silt at the bottom of the pond is neutral, the pond wall is tamped, and the disinfection work is done

2. Stocking: In the middle of May, loach seedlings are stocked, and about 50,000 loach seedlings are raised in ponds per mu.

3. Feeding: In May and June, feed 4% of the total weight of loaches, and in July and August, feed 8% of the total weight of loaches.

4. Disease prevention: regularly stir the bottom of the pond to discharge harmful gases.

1. Preparation for breeding

1. The depth of the pond is between, the pH value of the silt at the bottom of the pond is neutral (pH is 7), the pond wall of the pond should be tamped, and the water can not leak, it is best to build a drainage outlet and water inlet in the pond, and at the same time each mu of pond is equipped with 1 aerator.

2. 20 days before stocking loach seedlings, clean the pond with quicklime, and at the same time plant water spinach, lotus root, callus white, water hyacinth, water peanuts, etc. in the pond to help improve water quality.

3. 10 days before stocking loach seedlings, sprinkle an appropriate amount of amino acid fertilizer to remove weeds in the pond. 2-3 days before stocking loach seedlings, kill dragonfly larvae, water centipedes and other natural enemies.

2. Stocking and feeding

1. In the middle of May, loach seedlings are stocked, and about 50,000 loach seedlings are cultivated per mu of ponds.

2. Put 6 buckets of loach feed on the side of the pool, each barrel is filled with 5kg of special extruded feed for loaches, and after feeding for 3 consecutive days, the feed in the bucket is used up, and then 5kg of feed is loaded again to continue feeding. At first, the diameter of the feed is about the same, and after 10 days of feeding, the diameter of the feed is used, and then the diameter of the feed is fed after another 10 days, until the end of the month.

3. After a month of raising, feed with a special feeding machine, the feeding time is between 7-8 o'clock in the morning, and 2 feeding machines should be set up per mu of pond. In May-June, feed 4% of the total weight of loaches, and in July-August, feed 8% of the total weight of loaches.

3. Disease prevention

Regularly stir the bottom of the pond with a wooden stick to discharge the harmful gases from the bottom of the pond, and at the same time, copper sulfate ferrous sulfate mixture can be poured into the pond.

Fourth, temperature

The living water temperature of loaches is 10-30, and the optimal water temperature is 25-27.

Loach fish are farmed as follows:

1. It is best to choose wild artificial trapping for loach seedlings, the size of about 10g is appropriate, strong and not injured, because it is soilless breeding, so the water quality requirements are relatively high, and it is better to replace the flowing water in time.

2. In the breeding pond of loach fish, you can plant some aquatic plants floating on the water surface, used to give loaches summer shelter, aquatic plants can also swim in the sail group to purify water quality, in order to maintain the oxygen content of the car in the water, the coverage area of aquatic weeds should not exceed 70%, and the aquatic weeds should be fixed with a shelf, otherwise the follow-up management will affect the water quality habitat effect.

3. Attention should be paid to the feeding time and amount of loach feed, and the amount should be observed daily and adjusted in time.
