Culture techniques of Pelteobagrus fulvidraco how to raise Pelteobagrus fulvidraco

Pelteobagrus fulvidraco, presumably many friends living in rural areas are quite familiar with this kind of fish, and can often be seen in some small ponds in rural areas. With the wide understanding of Pelteobagrus fulvidraco, it is quite popular in the market. Many people want to cultivate this kind of fish, but they don't know much about its breeding methods.

How to raise Pelteobagrus fulvidraco

I. Pond conditions

At the bottom of the pond, it is best to use a mixture of sediment as the bottom of the pond, the pond must have a drain and irrigation outlet, or there may not be, but there must be a drain, and then the amount of water must be sufficient. The whole pond must be carried out for two weeks before the fish are released. First clean the fish pond and disinfect the water quality.

Aquaculture management

1. When it was fed some time ago, its main food source was to hunt small organisms and zooplankton in the pond, and when it was not enough to meet the growth needs of yellow fish, it could be fed artificially, and some fresh bait could be prepared twice a day.

2. Make an inspection every morning and evening to check the water quality, fish fry and food intake, clean up the excess and remaining bait, and then change the water according to the pollution and transparency of the water. generally, there is no special case is to change the water once a fortnight or so, and then use quicklime or bleach for disinfection.

3. It is necessary to prepare for overwintering at the end of autumn, and when the water temperature drops below 10 degrees after winter, it is necessary to do a good job of heat preservation, and at the same time disinfect the water quality in the pond. Bleach is also used for disinfection, and measures should be taken to sweep snow, replenish water and prevent diseases around the pond during the winter.

Culture techniques of Pelteobagrus fulvidraco

1. Pond conditions: Pelteobagrus fulvidraco has poor tolerance to hypoxia, so it has higher requirements for ecological conditions. it is necessary to choose a pond with sufficient water source, fresh water quality and convenient injection and drainage, with an area of 2-5 mu, flat bottom, silt 10-20 cm, water depth 1.5-1.8 m, and the pond inlet is filtered with 30-mesh sieve silk mesh to prevent the entry of wild miscellaneous fish and other enemy organisms.

2. Clear the pond to cultivate water: drain the pond water half a month before stocking, sprinkle and disinfect the whole pond with quicklime 125-150 kg / mu plus crystal trichlorfon 1.5 kg / mu, disinfect 5-7 days and inject about 80 cm of fresh water. 200 kg of fermented chicken manure or cow dung and dung per mu are used to cultivate water, and the seedlings can be released after 7-10 days.

3. Fish stocking: generally, Pelteobagrus fulvidraco summer flower fingerling is released in June, which requires strong physique, no disease or injury, neat specification, 2-4 cm yellow catfish summer flower, and the stocking quantity is 150000-20000 pieces / mu. A week after laying the fry, about 200 silver carp and bighead carp fry of about 20 centimeters per mu were put in to regulate the water quality, and the fry were soaked in 3% salt water for 15 minutes.

4. Daily management: the fish species keep a water depth of 70-80 cm when they just go into the pond, and then gradually deepen to 1.5-1.8 meters with the increase of water temperature. Control the water fertility of the pool, keep the transparency at 30-40 cm, and add new water regularly, generally every 10-15 days. To adjust the water quality of the pond, 10 kg / mu of quicklime was sprinkled once a month, and chlorine dioxide, a fungicide, was used to disinfect the water regularly once a month.

Feeding methods of Pelteobagrus fulvidraco

1. Feeding principle: it should be flexibly mastered according to scientific stocking quantity, water quality and different seasons, giving priority to uniform feeding and adequate feeding, not uniform feeding, and feeding as far as possible in accordance with the "four determinations" and "four looks" principles of scientific fish culture.

2. Feeding amount: the feeding amount of Pelteobagrus fulvidraco fingerling put into the pond was less at the beginning, and the scene of group feeding could not appear until 3-5 days later. It is generally believed that if winter fillet fry are put in, the feeding amount before April is 1% Mel 3% of body weight, and the peak growing season is 5% Mel 8% of body weight.

3. Feeding times: twice a day, one in the morning and one in the afternoon. If there is a floating head in the pond before the wee hours of the morning, in the case of increasing oxygen, the feeding time should be postponed appropriately, such as the original feeding at 8:00-8: 30 is changed to 9:00-9: 30.
