First, the pond water requirements

1, pond requirements

Pond culture of Pelteobagrus fulvidraco, the body of water to have a certain depth, must reach more than 2m, and to ensure that the water quality up to the standard, sufficient water, the bottom of the pond is flat, able to drain and irrigate, and the bottom is good. In general, Pelteobagrus fulvidraco likes clear and clean water, the transparency of the pond water should be maintained at more than 35cm, and the water body is best to have live water flow all year round. The pond area should be suitable and equipped with mechanical equipment such as oxygenator, pumping machine, bait casting machine and breeding fishing boat.

2. Strictly clear the pond

Whether it is a brand new pond or not, it must be strictly cleared and disinfected. The old pond to remove too much silt, retain the bottom mud about 10cm, the new pond requires a flat bottom, bottom mud leveling. Lime can be utilized to clear the pond dry, 150kg of lime per mu, fully mixed with the bottom soil and lime, the presence of pathogens in the pond, wild fish and other impurities completely removed.

3, timely water injection

After 7-10 days of pond disinfection, the pond is sufficiently exposed to the sun, can be injected into the high-quality aquaculture water, and set up a corresponding density of filters at the water inlet, to prevent the wild fish, hostile organisms and insect eggs into the pond. In addition to this injection of about 80cm of water, into the small fish and shrimp water test, to ensure the safety of the pond can be added to more than 2 meters of water, ready to stocking Pelteobagrus fulvidraco species.

4, full base fertilizer

In the stocking of fish species before, according to the pond water conditions, a one-time full base fertilizer, the whole pond evenly sprinkled, in order to cultivate water plankton, the specific dosage can be based on the actual conditions of the fish pond to decide, generally can be 150-200kg per acre dosage of fermented and rotted organic manure fertilizer.

Second, the fish fry put

1, fish fry requirements

more varieties of Pelteobagrus fulvidraco on the market, no matter what varieties to choose, should be selected from the formal Pelteobagrus fulvidraco breeding farms of the fish, try to choose the artificial breeding of the good fish, which not only ensures the purity of varieties and the growth rate, but also to improve the survival rate. This will not only ensure the purity and growth rate of the species, but also improve the survival rate. General requirements for individual specifications in the 10-15cm, weight 15-35g appropriate, fish species specifications, relatively good health, relatively fast growth.

2, stocking time

Pelteobagrus fulvidraco stocking time is generally in the second half of April each year, but the temperature varies from place to place, the specific to the actual situation prevail. Only the temperature conditions allow, the water temperature stabilized at about 10 ℃, can be stocked, in order to artificially extend the growth time.

4, stocking density

The stocking density of Pelteobagrus fulvidraco needs to be flexibly mastered according to the culture conditions, culture mode, bait supply, fish species specifications and management level, etc. If the main culture of Pelteobagrus fulvidraco, the general can be stocked with 2500-5000 tails of fish species of 15-35g per tail per acre, and the specification can be appropriately diluted when larger, and at the same time, it can be paired with bighead carp, bighead carpet fish species of about 200 tails; if the mixed culture mode is used, it can be used to stock the Pelteobagrus fulvidraco. If you use mixed culture mode, you can set up Pelteobagrus fulvidraco in other culture pools, and set up 100-150 fish species with more than 30g per mu.

4, Notes

Before putting the fish fry, we must put the fish seeds to test the water for more than 12 hours, no problem before putting the seeds, so as to avoid accidents. Before the fish seed into the pond, you need to use 5% salt water solution to disinfect the body by dipping for 10-15 minutes to avoid bringing pathogens and other harmful organisms into the pond.

3, feed feeding

1, bait requirements

Pelteobagrus fulvidraco breeding can choose a purely animal feed, including small shrimp, small fish, earthworms and other common feeds to ensure that the feed has a certain amount of protein, fat, vitamins, and may be appropriate to add other feed. In the daily baiting, it can be reasonably proportioned according to the weight of the fish and the type of raw materials to be put in. In the artificial feed with, can be appropriate to add fish meal, vegetable cake, soybean cake, the second powder, rice bran, enticement to promote the growth of additives.

2, reasonable feeding

The amount of bait should be based on the number of fish, feeding, water quality, water temperature, weather and so on, Pelteobagrus fulvidraco because of the small individual, slow feeding, feeding should pay attention to? The first thing you need to do is to start feeding as early as possible, and to feed less and more often. Before and after April, the daily feeding 2 times, baiting 1%-3% of the weight of the fish; May-September, the daily feeding 3-4 times, baiting 3%-5% of the weight of the fish; after October, as the weather turns cooler, the fish body weight, you can feed 2 times a day, the baiting amount of 1%-2% of the weight of the fish.

3, taming methods

Natural wild Pelteobagrus fulvidraco prefers daytime and nighttime feeding, so it must be tamed and trained to adapt to daytime feeding, which generally requires about 1 week of taming. When domestication, can be sprinkled along the edge of the pool along the edge of the minced fish, about 2 consecutive days to be fish species successively swim to feed, and then gradually add processed bait in the minced fish and fixed-point put, and then switch to the whole artificial feed fixed-point, regular, quantitative feeding.

Four, feeding management

1, water quality regulation

Pelteobagrus fulvidraco prefers fresh water environment, the water quality should be observed at any time, to maintain the water quality fresh, it is necessary to change the water on a regular basis. 5-June generally can be changed once a month, each time the injection of new water of 30cm or so; July-September generally every half-month water change, each time the injection of new water about May-June can generally change the water once a month, each injection of new water about 30cm; July-September generally every half a month to change the water, each injection of new water about 15cm, throughout the year to maintain the depth of water at about 2m.

2, timely oxygenation

Ponds should be according to the weather, water quality, scientific boot oxygen, sunny days adhere to the early morning and afternoon boot 1 hour, rainy, hot weather to advance oxygen, increase the number of times and time to boot, so that the water body dissolved oxygen concentration of more than 3mg/L.

3, the water is the most important part of the water, but the water is also the most important part of the water, the water is the most important part of the water.

3, disease control

Pelteobagrus fulvidraco is more resistant to disease, if you can control the water quality according to the requirements, and do a good job of routine disinfection and prevention, there are generally very few diseases, so in the prevention of disease should be carried out ? The main focus is on prevention. Approach, half a month available lime regulation to improve water quality, but also can use chlorine preparation for water disinfection. Once the disease occurs, it is necessary to timely diagnosis and treatment, as soon as possible symptomatic medication.

4, strengthen the management

Adhere to day and night pond patrols, careful observation of fish feeding, activities and growth, once found hidden trouble, should be excluded in a timely manner. Minimize the number of pedestrians, animals, etc. into the breeding area to disturb the fish, to avoid the occurrence of stress.
