How much is the sweet-scented osmanthus fish "one of the four famous freshwater fish" per jin? What are the stocking skills?

Sweet-scented osmanthus fish, as "one of the four famous freshwater fish", are welcomed because of their delicious taste and meat. Breeding sweet-scented osmanthus fish has also become a way to get rich. So how much is the sweet-scented osmanthus fish per jin? What are the stocking skills?

How much is the sweet-scented osmanthus fish per jin?

Mandarin Fish's market price is not stable, and its price will change due to different regions and production problems, but in general, Mandarin Fish's market price is about 30-60 yuan per jin. In addition, Mandarin Fish's price is also affected by market demand and supply. For example, when Mandarin Fish is farmed in the north, natural cinnamon fry caught in the south or artificially cultivated osmanthus fry are mostly purchased. The seedlings of the north can not meet the needs of production, and Mandarin Fish seedlings still have a series of problems during transportation, which will affect the growth quantity of Mandarin Fish, so Mandarin Fish in the north sells more expensive. while the south uses artificial breeding technology and good breeding technology, higher output, so generally speaking, the price of Mandarin Fish in the south is cheaper than that in the north.

2. Stocking skills of osmanthus fish

1. Preparation before stocking

Check whether the inlet and outlet are in good condition before stocking to prevent leakage. Secondly, it is necessary to observe the situation of stocking water, especially to understand the situation of escaping fish in ponds, so as to determine the species and quantity of stocking; finally, the water body should be improved. For example, the water body is generally turbid, there are many dirt in the water, the water quality is very poor, and the germs are easy to reproduce. Chemical water waves such as quicklime or inkstone are applied to clarify the water body and purify the water quality. If the water body is too thin, it is necessary to apply fertilizer and cultivate natural bait in the water.

2. Stocking operation

In order to reduce the stocking death and ensure the stocking effect, fish species should be restocked. The selected fish species require scale fins to be neat, leaping forcefully, swimming lively, physically hypertrophic, disease-free and injury-free. Fish that are thin, slow to respond, hyperemia on the body surface and mechanical damage should be removed. The stocking species can be determined according to the source of the fish species and the needs of effective culture, but the stocking scale should be much better, and the stocking density can be released persistently, so as to make the adult fish meet the commercial specifications at the end of the year, reduce the adverse effects caused by the short growing period, and ensure the benefit of culture. During stocking, the fish must be disinfected with medicine and then put into the water body to prevent the fish from entering the pond with disease and causing the spread of fish disease. Generally, 3~5min can be soaked in 2%-3% saline or 1-2mg/L crystal trichlorfon.

3. Management after stocking

After stocking, baiting, fertilization and water quality regulation should be done according to the species and quantity. Fish disease prevention and other work. Feed is generally based on concentrate to speed up the growth of fish. The daily feeding amount should be 5%-8% of the total fish in the pond, with a little surplus after feeding. If there are more fertile water fish such as silver carp and carp in the pond, more fertilizer can be applied, and a small amount of fertilizer should be applied for many times. The organic fertilizer should be fully fermented and applied into the water body with 50 kg per 667m2. Ammonium bicarbonate (per 667m25~8kg) or urea (per 667m23~5kg) can be used to pour wine in the whole pond to improve the water quality. Within 7 ~ 10 days after being raised, 0.3m/L and 1m/L were sprinkled to kill bacteria, and crystal trichlorfon (0.4mg/L) could be used at intervals. The mixture of copper sulfate (0.5mg/L) and ferrous sulfate (0.2m/L) sprinkles wine to kill parasites and effectively prevent the occurrence of fish disease.
