For the profit of mandarin fish culture, 80% of bait is the biggest cost.

According to the calculation of cultivating one mu of mandarin fish, the profit is about 20, 000 yuan, and the mandarin fish culture is mainly divided into early cinnamon, middle cinnamon and late cinnamon, the price of early osmanthus is about 40 yuan per jin, and the profit per mu is about 20, 000 yuan. The price of Chinese osmanthus is about 35 yuan per jin, the profit per mu is about 17500 yuan, the price of late cinnamon is about 50 yuan per jin, and the profit per mu is about 25000 yuan. Bait is the largest input in the process of mandarin fish culture. The proportion can reach more than 80%.

Mandarin fish culture is mainly divided into early cinnamon, middle cinnamon and late cinnamon. Early cinnamon is generally released at the end of March or early April, and fish is released from August to September; Chinese cinnamon is generally released from May to July, and fish is sold from October to December; late cinnamon is generally released from August to September, and fish is sold from April to August of the following year.

The cost of raising mandarin fish

The cost of mandarin fish culture includes buying seedlings, buying bait fish, renting venues, breeding tools, and so on. Only by choosing high-quality seedlings to develop relatively high-quality mandarin fish can economic benefits be improved. The price of mandarin fish will be different if the time period is different.

The general fry is about 3-10cm, the early mandarin fish is about 0.20-0.25 yuan per centimeter, and the middle and late mandarin fish is about 0.13-0.15 yuan per centimeter. During the culture period, the early mandarin fish should be released in April, about 2000 seedlings per mu, about 4000 seedlings per mu in June, and 5000 seedlings per mu in the evening.

Among them, the largest cost of culture is the input of bait fish, if the cost of bait fish can be controlled down, then the profit of mandarin fish culture will be high. Because the bait given to the bait fish in the market is different, so the meat quality and quality are also different. at present, the bait fish needed for a jin of mandarin fish in the market is about five jin, while some farmers give fish larvae of mud carp seed to the mandarin fish, which can reduce the cost of mandarin fish by about 4 yuan per jin.

The profit of raising mandarin fish

Early osmanthus: the price of early osmanthus is relatively high, but it can only be sold before September before it can be sold at a high price. The price is generally about 40 yuan per catty, so early osmanthus is mainly released early, with a lower density, about 2000 tails per mu. If the density is low, the yield can be increased, and the profit per mu can reach about 20, 000 yuan.

Zhonggui: the price of Zhonggui is the lowest among the three, and the price is stable at about 35 yuan. If you deploy your own bait fish, the cost will be reduced a lot. If you release fish fry early, the more important thing for culturing Zhonggui is to reduce the cost. The profit per mu can reach about 17500 yuan.

Late cinnamon: late cinnamon is the most expensive of the three, and the price is about 50 yuan, but it takes a long time for late cinnamon culture, the cost will be relatively high, and it is easy to lead to poor physique of mandarin fish, and the probability of infection is high. Therefore, during the period of late cinnamon culture, the daily management should pay more attention than usual. Under normal circumstances, the profit per mu can reach about 25000 yuan.

Several points that should be paid attention to in daily management

1. Disease control. In fact, the incidence frequency of mandarin fish is not very high, the major impacts are water quality disease, rotten Gill, hemorrhagic disease, enteritis and so on, in which the harm of virus disease is relatively great, so we should pay attention to prevention to ensure the quality of mandarin fish.

2. Inspection and inspection. Always inspect the pond to see if there are dead fish, and fish them out and sell them in time, because dead mandarin fish can also be sold, but the price is half that of live mandarin fish. Observe whether the amount of bait fish is sufficient and whether the mandarin fish is active.

3. Water quality management. Because mandarin fish have relatively high requirements for water quality environment, the common water quality is high in ammonia nitrogen, water mixture, high nitrite and so on.
