How to raise the fish salvaged from the Songhua River

1. Mixed culture. Pelteobagrus fulvidraco is cultured in other fish ponds, and some wild miscellaneous fish and shrimp in the pond can be used. There is no need to feed Pelteobagrus fulvidraco separately. If you put 100 fish species with specifications of about 35 grams per mu, you can get 10mur15 kilograms of commercial Pelteobagrus fulvidraco. The stocking specifications of yellow croaker species should not be too small, and other ferocious carnivorous fish, such as big mouth catfish and snakehead, should not be raised in the pond. 4. Water quality management.

2. Pelteobagrus fulvidraco mostly lives in the shallow waters around the lake and rivers entering the lake, especially in still water or slow-flow shoals, where there is more humus and mud.

3. It is called silver scale. Because the skin is yellowish green, the white tooth is called Pelteobagrus fulvidraco. It belongs to the specialty of Nenjiang River and Songhua River Basin and is a variety of Pelteobagrus fulvidraco.

4. The scientific name of the fish is Pelteobagrus fulvidraco. This kind of fish gets its name because its sound is similar to "Gah ah". There are many local common names, such as Gaya Zi, yellow wax fish, spike fish, yellow dinned fish, yellow wax socks, Yuyangsi, Gapi spring fish and so on. Different regions have different names, such as "Anniu" by Shanghainese, "Wang Nailtou" by Suzhou, "Gayazi" by northeastern people, and Ang thorn fish by Ningbo people.

5. The scientific name of Gayazi fish is silver scale, because its skin is yellowish green. Gaya Zijian is called Pelteobagrus fulvidraco, while the white one is called Pelteobagrus fulvidraco. Baiga manuscript friend Ziyazi is a specialty of Nenjiang and Songhua River basins and a variety of Pelteobagrus fulvidraco. They belong to the class bony fishes, the subclass Orthoptera, the catfish order, and the family Carpinidae.

Culture techniques of Pelteobagrus fulvidraco

Pay attention to the regulation of water quality and the prevention and treatment of diseases: Pelteobagrus fulvidraco has higher requirements for water quality, keep the transparency of water 35 to 45 cm, PH value 5 to 8, change water once a month, install an aerator in the pond, turn on the machine regularly or irregularly, increase the dissolved oxygen in the water, avoid or reduce the phenomenon of floating head or flooding pond, so that the growth of Pelteobagrus fulvidraco is normal.

Cultured Pelteobagrus fulvidraco can choose pure animal feed, including shrimp, small miscellaneous fish, earthworms and other common feed to ensure that the feed has a certain amount of protein, fat and vitamins, and other formula feed can be added appropriately. In the daily feeding, a reasonable proportion can be made according to the weight of the fish and the kinds of raw materials. In the artificial feed, fish meal, vegetable cake, bean cake, secondary powder, rice skin bran, food inducement and growth promoting additives can be added properly.

Aquaculture technology: pond culture. If the artificial breeding seedlings are put in, if the natural seedlings are put in, the growth rate will be slow, the specification is not neat, and the survival rate is low. Mixed breeding. Yellow spicy Ding is raised in other fish ponds. Water quality management. Yellow chili Ding is less resistant to hypoxia than conventional fish, likes clean water, should be injected with new water regularly, and the pond water should not be too alkaline. Prevention and treatment of fish disease. Yellow spicy Ding has strong disease resistance, and there is generally no serious disease in breeding.

Seedling cultivation: 10 ~ 120000 seedlings per mu (1 mu = 667m2), which can be fertilized and watered down the pond to cultivate biological bait, and can also be sprinkled with soybean milk, peanut cake or egg yolk. After raising to the specification of 3cm and 4cm, it was cultivated in separate ponds, 30,000 to 40,000 per mu, and then entered the stocking stage after being raised to the specification of 6cm.

Ponds: for breeding Pelteobagrus fulvidraco, we should choose rivers and ponds with adequate water sources and convenient drainage and irrigation. Mixed culture: silver carp, bighead carp and bait fish can be put in the pond. Water quality: the water needs to be changed every half a month or so to keep the water clean. Disease prevention: antibiotics should be put into the feed to prevent Pelteobagrus fulvidraco from being infected with rotifer, water mold and so on.

How to raise gaga fish?

The main results are as follows: 1. There are more low-value wild mixed fishes in river ditches, and mixed culture of Pelteobagrus fulvidraco can save artificial bait. Large water surface mixed culture of Pelteobagrus fulvidraco has high population yield, which does not affect the yield of the main species and does not need additional bait.

2. Fish culture methods Pond selection and cleaning disinfection choose fish ponds with good water quality and adequate water sources, with a water depth of more than 5m and an area of 2 to 10 mu. For ponds whose bottom silt exceeds 10cm, excessive silt must be removed. After removing too much silt, do not immediately inject water, but should be exposed in the sun for several days, and then clean up and disinfect.

3. Mixed culture. Pelteobagrus fulvidraco is cultured in other fish ponds, and some wild miscellaneous fish and shrimp in the pond can be used. There is no need to feed Pelteobagrus fulvidraco separately.

It is distributed in Pearl River, Minjiang River, Xiangjiang River, Yangtze River, Yellow River, Haihe River, Songhua River and Heilongjiang River in China. it has high edible value and economic value. The scientific name of fish species is Pelteobagrus fulvidraco.

2. Galea is a kind of catfish. The catfish, also known as Pelteobagrus fulvidraco, belongs to the family Siluridae. This kind of fish may have different names in different regions, such as yellow bone fish, yellow girl and so on. The fish has a yellow body and has long tentacles and dorsal fins. They mainly live in freshwater environment, such as rivers, lakes and other waters. Garfish is a kind of benthic fish, which likes to live in the bottom waters.

3. Gayu is a river fish. Pelteobagrus fulvidraco (Pelteobagrus fulvidraco, Pelteobagrus fulvidraco), Pelteobagrus fulvidraco, Pelteobagrus

I have not done any research in this area either. It seems that apart from carp feed and dog food, it is also a favorite food for fish. Occasionally feed some boneless fish, snake meat, mice and other fresh food, will win the love of the fish. I hope my answer will be helpful to you.

The mixed culture of parent fish pond can not only make full use of the water space of parent fish pond and improve the utilization rate of parent fish pond, but also eat some small wild fish competing with parent fish for oxygen consumption. Mixed culture of Pelteobagrus fulvidraco in adult crab ponds can make full use of natural bait biological resources in crab ponds. The mixed culture of Pelteobagrus fulvidraco can save artificial bait.

Natural wild Pelteobagrus fulvidraco must undergo domestication training and generally need to be domesticated for about a week. During domestication, a fixed feeding signal such as tapping on the feed bucket is used to carry out fixed-point and regular feeding training, first using bait to attract fish species along the edge of the pool, waiting for the fish to swim one after another for about 2 days to feed, and then slowly adding artificial feed into the bait, fixed-point into the pool fixed place, and finally make Pelteobagrus fulvidraco develop the habit of fixed-point and regular feeding. Reasonable feeding.

When breeding fish, first of all, we need to choose a suitable pond and clean up and disinfect. The ideal pond should be located in a place with sufficient water source and good water quality, with a water depth of more than 5 meters and an area of usually 2 to 10 mu. For ponds with more than 10 cm of silt at the bottom, excessive silt should be removed. After removing the silt, let the pond be exposed to the sun for a few days before cleaning and disinfection. Then there is the stocking of fish species and the collocation of species.

The scientific name of the fish is Pelteobagrus fulvidraco. Also known as Huang Zi Ding, Ga Yazi, Huang Gu Zi, yellowfin fish, yellow thorn bone, spike fish, catfish beard and so on. The quack fish can make a quack sound by rubbing and colliding with the bones on the back, so it is called the quack fish. Gayu likes low light and is afraid of strong light, so it often sleeps during the day and goes out at night to find food, resting underwater during the day and looking for food at night.
