What is the price of herring in 2019? What are the breeding techniques?

Herring is a large economic fish, only distributed in the plain area south of the Yangtze River in China, rich in a variety of minerals, is the top grade of freshwater fish. What about the price of herring in 2019? What are the breeding techniques?

The price of herring in 2019

In the herring market, it is mainly divided into three species: freshwater herring, black carp and Chinese dace, and the prices of these three species will be slightly different in different producing areas.

The above prices are all reference prices, and the specific prices are subject to the actual local prices.

II. Culture techniques of herring

1. Water conditions

Aquaculture had better be close to areas with sufficient water sources to ensure that the water sources are pollution-free. The supporting facilities for electric power and irrigation should also be fully prepared, and it is best to be equipped with pumping, oxygen and other equipment at the pond mouth. The best area of the aquaculture pond is 0.3 to 0.7 hectares, ensuring the light and ventilation of the pond, the final trimming of the bottom is regular and flat, and the best water depth is 2 meters.

2. Pond disinfection

Do a good job in the cleaning, cleaning and disinfection of the pond in the dry season, such as properly cleaning the silt and other sundries in the pond, but keep 0.1 meter thick silt at the bottom of the pond, and then repair and strengthen the pond embankment to ensure reasonable water quality and water quantity inside the pond during the culture period. After the cleaning and disinfection work is finished, it should be exposed to the sun for about 20 days, and then 120 kilograms of quicklime per mu with water will be configured into a solution to sprinkle every corner of the pond. Finally, the sludge in the pond is turned over with relevant tools to further integrate the lime solution with the sludge, so as to eliminate bacteria and other harmful substances as much as possible.

3. Bait cultivation

About 9 days before fish stocking, organic fertilizer should be applied at the bottom of the pond, generally using a mixture of quicklime and chicken manure as organic fertilizer to ensure that the amount of organic fertilizer per mu is about 280 kg. Two days later, amino acid fertilizer and water ointment was applied to the pond to ensure that the dosage was 1 kg per mu. The main function was to cultivate benignant plankton such as cumulus, and to provide sufficient bait for fish released in the later stage. During the actual culture period, amino acid fertilizer and water ointment should be applied every 11 days, and 0.8 kg per mu should be applied to replenish the nutrition of plankton in pond waters, improve its breeding speed and expand its distribution area.

4. Feed

Pellet feed for herring is more suitable for pond culture because this kind of feed has higher protein content and fuller particles. The number of feeding should be about four times a day, and the amount of feeding should not exceed 5% of the overall weight of the herring. In addition, different live biological baits can be fed according to different seasons. In early April, live snails can be put into the pond with a quantity of 300 kg per mu, and a replacement will be made in August according to the amount of 200 kg per mu.

5. Disease prevention and treatment

Herring has a strong ability of disease resistance, so as long as we adhere to the policy of giving priority to prevention and supplemented by treatment, the incidence of herring can be greatly reduced. Chlorine-containing preparations and other common disinfection agents can be used regularly to spray the pond area in all directions, which can not only effectively regulate the water quality, but also prevent bacterial diseases of herring. Feeding bait made of traditional Chinese medicine and multivitamins to the pond can effectively prevent diseases such as Gill rot and enteritis of herring. If the disease of herring is found, it should be diagnosed immediately, prescribe the right medicine to the case, and use drugs to avoid high toxicity.

Herring, as one of the important farmed species of freshwater fish, plays an important role in freshwater fish culture in China. And herring has the fastest growth and the highest price among the four domestic fish, so it is favored by farmers and consumers, and has important economic value.
