How to cultivate floral silver carp

Silver carp is widely favored by the public because of its large and delicious head, and its fish head is also used as the preferred material for famous dish Steamed Fish Head with Diced Hot Red Peppers, which has a great market prospect. Silver carp is a kind of aquatic fish, which is very suitable for breeding in fresh water and can bring good economic benefits for farmers. What are the breeding methods of silver carp? Many people don't know much about this, so let's learn about it with the editor.

How to raise silver carp

1. Preparation work: the water area of fish stocking is required to be 4Mu and the water depth is 1.5-2m. Appropriate amount of organic fertilizer should be applied to improve nutrition in water before stocking.

2. The stocking time and culture mode of fish species: generally from May to June, to avoid the peak of rotifer in the pond. The stocking method generally adopts mixed culture, which can give full play to the utilization rate of water body and the more economical utilization of food. Can breed a little silver carp and carp.

3. Daily observation: patrol the pond once a day to observe the dynamics of water color and fish, eliminate weeds and rotten debris in the water, clean the table and disinfect the table and food.

4. preventive measures: keep the stocking ponds hygienic; regularly draw nets to check the growth and disease of fish, so as to reasonably establish the amount of bait and the methods of prevention and control of fish diseases, and do a good job in the prevention and control of escape, theft, fish diseases and enemy diseases.

5. Feeding requirements: silver carp species mainly feed on plankton, and the pond water requires more fertile planktonic biomass. In addition to applying base fertilizer before stocking, green manure and cooked manure should be applied after summer stocking, and new water should be injected regularly to keep the nutrition balanced. Manual feeding should pay attention to timing, positioning, quality and quantity.

Culture techniques of silver carp

1. Set up fish ponds

If you want to cultivate silver carp in large quantities, you must establish a suitable fish pond. this kind of fish requires a relatively large fish pond area, preferably between 4 and 8 mu, with a water depth of more than two meters, and should be cultivated with organic fertilizer before releasing fish fry. Organic fertilizer can choose to apply cooked animal manure or cake fertilizer, but the fertilizer should be appropriate, not too concentrated.

2. Stocking fish fry

Cultured silver carp should be released every summer, which can be divided into monoculture or mixed culture. Huiyang, that is, when the fry of silver carp is put into the fry of other species, it can maintain the balance of ecological environment in the fish pond. conducive to the growth of all kinds of fish, but also can create higher economic benefits, silver carp is most suitable for farming with carp, silver carp and other fish.

3. Daily management

Silver carp usually take the plankton in the fish pond as the main food, so the water quality of the pond must be kept fertile and the number of plankton is high, so as to provide sufficient food for silver carp. In addition, during the period of breeding silver carp, when artificial feed is put into use, the principle of timing, quality and quantity must be maintained. Only in this way can the utilization rate of silver carp feed be improved.

4. Overwintering management

When the temperature drops obviously in late autumn and early winter, the activity of the silver carp will be reduced. when the temperature drops below 10 degrees, the silver carp will hardly eat. It is necessary to take out the lotus fish from the pond and concentrate them in the deeper fish ponds. If there are no conditions, it is necessary to sell all the silver carp fish after emptying and restocking the fry after the weather is warm in the coming year.

The difference between silver carp and silver carp

1. Water level difference

Silver carp: silver carp lives in the upper layer of the water and feeds on phytoplankton such as diatoms and green algae.

Silver carp: silver carp lives in the middle and upper layers of the water and feeds on zooplankton such as water fleas.

2. The difference between fish heads

Silver carp: the head of silver carp is relatively smaller than that of silver carp.

Silver carp: the head of silver carp can account for 1 stroke, 2 or more of the body.

3. The difference of body color

Silver carp: there are light black spots on the silver carp.

Silver carp: silver carp has all white scales and no black spots.

4. Abdominal difference

Silver carp: the abdomen of silver carp is angled, that is, there is an obvious crease in the center of the abdomen.

Silver carp: the abdomen of silver carp is smooth and has no crease.

5. Meat quality difference

Silver carp: the meat of silver carp is slightly loose, the taste is not as good as flower silver carp, and there are more small thorns, so it is not convenient to eat.

Silver carp: the meat of silver carp is delicate, and the fish head is rich in glial protein, which is most suitable for Steamed Fish Head with Diced Hot Red Peppers, garlic fish head and so on.

What kind of food does silver carp eat

The main results are as follows: 1. silver carp is a typical filter-feeding fish. it filters out the plankton in the water by the special structure of the gills, feeds on plankton for life, mainly eats zooplankton at the fry stage, and gradually changes to phytoplankton when it is more than 1.5 centimeters long. and like to eat grass carp feces and put chicken, cow dung, also eat soybean milk, bean dregs powder, wheat bran and rice bran, more like to eat artificial microparticle compound feed.

2. Silver carp are interested in sour food and have an appetite for bad food. Silver carp like to eat rotten food, often with grass carp to feed silver carp to eat grass carp feces, so there is a grass to raise three silver carp.

3. The diet of silver carp has obvious seasonality. In spring and autumn, in addition to plankton, a large number of spoiled baits are eaten. The lower the water level in summer, the greater the food intake, and eat less in winter.

At present, the culture of silver carp is still very promising in the market, and experienced farmers can consider it, which may bring relatively rich economic benefits. However, after all, the aquaculture industry has certain risks, so we must consider carefully before breeding.
