Practical experience of culturing Pelteobagrus fulvidraco

Pelteobagrus fulvidraco, also known as yellow wax ding. Belong to omnivorous benthic fishes, like clusters, inhabit the bottom of the water body, feeding and activities under low light conditions.

The area of the fry culture pond is 10mur20 square meters, the water depth is 0.7 meters, it is rectangular, the bottom of the pond is flat, and the bottom is paved with tiles or flattened with cement.

The larvae that have just hatched their membranes can release 8000 fish per cubic meter of water, with a stocking density of 4000 fish per cubic meter of water, and 20003,000 fish fry per cubic meter of water.

Adhere to the "Siding" feeding principle, according to the size of the fish, feed natural feed and artificial mixed micro-pellet feed or artificial mixed powder feed.

The intensive cultivation of fish fry in the running water cement pond has a high stocking density and a lot of impurities and feces, so the dirt at the bottom of the pond should be sucked out regularly with a straw. Check whether the fish fry is sick every day, and timely measures should be taken to treat the disease.

Pelteobagrus fulvidraco ponds mainly raise Pelteobagrus fulvidraco adult fish with an area of less than 3 mu and a water depth of 1.5m. The sandy soil at the bottom of the pond is required to retain water and fertility. The import and export water should be protected against escape nets to prevent fish escape and carp and crucian carp from mixing into the fish pond.

Flatten the bottom of the pond and dig out a pit culvert of about 50 square meters at the bottom of the drain end, which is 25 centimeters deeper than other places, so as to facilitate adult fish fishing. Before releasing the seedlings, disinfect them with quicklime to remove wild miscellaneous fish.

The stocking density of fish fry is generally about 3 cm, with a stocking capacity of 5000 fish per mu, and a fish fry of about 5 cm per mu, with a stocking capacity of 45005500 fry per mu.

There are two kinds of feed for adult Pelteobagrus fulvidraco: pure animal feed and artificial compound feed. Pure animal feed: including small fish, shrimp, aquatic and terrestrial earthworms and so on. Artificial formula feed requires 38% crude protein.

Adhere to the "four fixed" and "four look" bait principle. The daily feeding amount depends on the relationship between the total body weight of Pelteobagrus fulvidraco and water temperature. When the water temperature is 10 ℃, 1.5 ℃, 2.5%, and 45% of body weight, respectively.

Do a good job in the daily management of pond, such as feed management, water quality management and fish disease prevention. Inspect ponds frequently, weed and decontaminate frequently, catch sick fish and dead fish, and keep records.

Pelteobagrus fulvidraco cage feeding cage feeding Pelteobagrus fulvidraco can be raised not only by large floating cages on large water surface, but also by small cages in ponds. Here, we mainly introduce the technique of setting up small cages in ponds.

The pond with net cage requires adequate water source and fresh water quality, with an area of 5muri 10 mu and a water depth of 2Mel 2.4 meters. Before setting up the cage, the pond should be thoroughly cleaned and disinfected with drugs such as quicklime or bleach.

The cage is made of polyethylene mesh, the mesh specification is 1 Mel 1.5 cm, and the cage size is generally 4 × 2 × 2 meters. The cage is fixed and shaped with 6 bamboo poles and inserted into the pond. The set area of the cage shall not exceed 50% of the total area of the pond.

The stocking time of Pelteobagrus fulvidraco is generally from the beginning of June to the end of July, the stocking specification is generally more than 5 centimeters, and the stocking density is generally 600 fry of Pelteobagrus fulvidraco with more than 5 centimeters per square meter. Fish fry should be strictly disinfected during stocking to kill parasites and pathogenic bacteria on the body surface.

Feed. Feed should be given strictly in accordance with the "Siding" feeding method, and should not be fed with rotten and deteriorated feed. Pure animal feed can be kneaded directly into a ball and fed; compound feed can be fed by a small amount of times. The daily dose is 2 Mel 3 times, and the feeding amount is 4% of the fish's body weight.

The ponds with cages should be filled with new water regularly and sprinkled with quicklime to improve the water quality. Inspect the cage twice a day in the morning and evening to check whether the cage is damaged; the cage should be regularly sprinkled with 0.04% iodized salt and 0.04% baking soda mixture for disinfection; remove the residual bait in time; clean the net clothes regularly to maintain a good exchange of water in the cage.
