How to raise herring feed formula for herring

I want to raise fish, herring, fish, flower face, grass carp.

Herring is one of the main farmed fish of freshwater fish in China, and there are many farmers who breed herring, thenWhat kind of feed is used for herring farmingThis?

First, the introduction of herring

Herring is one of the four major carp in freshwater aquaculture in China, and the other three are grass carp, silver carp and bighead carp. Scattered filial piety.

The main growing area of herring is the plain area south of the Yangtze River in China, and the distribution of herring in the north of the Yangtze River is relatively scarce.

The shape of the herring is cylindrical, with a flat and round abdomen and no ventral ridges. The tail is slightly flattened. The snout is blunt, but more acutely protruding than that of grass carp.

Because herring is not very active by nature, it generally moves in the middle and lower layers of the water body, and its food is mainly snails, mussels, clams, clams, etc., in addition to artificial feed.

2. What kind of feed is used for breeding herring?

The commonly used feed for breeding herring is soybean cake, silkworm pupae, green hay, fish meal, barley and rapeseed cake and other mixed feeds that are matched together in different proportions. In addition, you can feed some screws, clams, young mussels, shrimp, earthworms, corn, sweet potatoes and potatoes. If you fish for herring, you can use nest material to lure fish, and the bait can be matched with the above.

The specific recipe is as follows:

1. 35% soybean cake fish meal, 1% yeast, no imitation machine salt, etc., the bait coefficient is;

2. 40% hay meal, 30% silkworm pupae, 10% vegetable cake, 20% barley, and the bait coefficient is 3;

3. 5% of fish meal, 35% of soybean cake, 18% of wheat bran, 15% of corn, 10% of soil surface, 5% of yeast, 10% of vegetable cake, 1% of multi-dimensional inorganic salt, 1% of soybean oil, crude protein, feeding varieties and methods: mainly herring, polyculture of silver carp, bighead carp, etc., feed coefficient.

1. Breeding pond: Generally speaking, herring is raised in a large area and can be used as an economic fish culture. Therefore, a breeding pond is needed, and the herring should be disinfected before being put in.

The location of the breeding pond also needs to be paid attention to, and try to choose a place with a good ecological environment and sufficient water sources. Also, it is better to be upwind as well as upstream of the water source.

2. Feeding: Breeding herring should be fed regularly. Generally speaking, it can be done twice a day, once at 8-9 a.m. and once at 2-3 p.m.

They can be fed some fish, shrimp and other meat, or they can be fed special feed. Rationing should be given at each feeding, and it is best to let them finish within hours and not overfeed them.

3. Water quality: When breeding herring, water quality is also an important factor. In general, it is best to keep the transparency of the water between 25-40 cm. If the water quality is relatively turbid, the water can be changed appropriately.

4. Oxygenation: Herring also has requirements for the amount of dissolved oxygen in the water. If the oxygen content in the water is insufficient, artificial oxygen can be used to supplement part of the oxygen.

5. Disease prevention and control: herring fish are sometimes more likely to get sick. Especially when the herring is still relatively young, it is more likely to get "hemorrhage", and 2-year-old fish are more likely to get "gill rot" and other diseases.

It is necessary to prescribe the right medicine according to the types of these diseases, and prevent and treat them in a timely manner to avoid further expansion of the harm.

1. Fish pond construction.

The location of the fish pond for herring farming is the basic condition for aquaculture, and we cannot choose the breeding site at will. In fact, the requirements for herring fish ponds are not high, as long as the transportation is convenient, the water source is sufficient, the water quality is pollution-free, and the feed resources are abundant. If it is an old pond, you only need to clean the fish pond; The new pond is to be dug and built by itself, generally depending on the scale of the culture.

Secondly, we need to arrange the drainage and water injection outlets, and at the same time the basic production equipment for breeding must be fully equipped, as well as aerators, feeding machinery, drugs, etc.

2. Disinfection of clear ponds.

Whether it is a new pond or an old pond, the fish pond needs to be cleaned and disinfected before breeding. The old pond needs to clean out the silt of the pond, and then disinfect it with about 100 kilograms of quicklime, and the water depth is controlled at about 30 centimeters when the pond is cleared. The new pond only needs to clean out some debris in the pond and then disinfect it with about 75 kilograms of quicklime.

After the pond is cleared, the pond water should be discharged, and then new water should be injected, and the seedlings should be put seven to ten days before the seedlings are released, and an appropriate amount of organic fertilizer should be applied to cultivate the fertilizer water.

3. Select seedlings and put seedlings.

When we select herring fry, we generally require the selection of robust, disease-free, mechanical damage-resistant, high-quality fry. The second is that the size of the fry should be neat, so that it is convenient for breeding and management. When stocking, the fry should first be soaked and washed with drugs, and then test-raised, and then put the fry into the pond after the trial-raising is successful.

When stocking, it is necessary to choose a time when the weather is fine, and it must not be carried out on a rainy day. The stocking density of herring culture can be 2,000 to 3,000 per mu when there is an aerator.

4. Bait feeding.

Herring is mainly fed with snails, which means that it is a carnivorous fish. In addition to snails, mussels, clams, clams, shrimp and insect larvae are all used as feed for herring. However, during the jade fry period, herring mainly feeds on zooplankton in the water.

When feeding the herring, we should feed it regularly, quantitatively, qualitatively, and positionally according to the herring's feeding situation and weather changes. Feeding is done four times a day from April to June, three times a day from July to September, and twice after October.

5. Water quality management.

After each feeding of the herring, we must clean up the remaining feed residue in time, otherwise it will pollute the water quality. Secondly, the aerator needs to be turned on at noon on a sunny day, in the morning on a cloudy day, and in the middle of the night on a continuous rainy day, otherwise the amount of dissolved oxygen in the water will be insufficient. Then we need to change the water at the right time, and each water change only removes one-third of the total water volume of the pond.

There is also a reasonable fertilization, to ensure the fertility of the water in the breeding pond, fertilization is mainly organic fertilizer, usually can also use a small amount of chemical fertilizer. Finally, it is possible to use the special microbial adjustment for fish farming to adjust the water quality and reduce the harmful substances in the water body.
