Freshwater lobster culture cost

The improved variety has the advantages of fast growth, wide adaptability, high yield, strong stress resistance, large number of eggs, large individual and so on. After several years of observation, experimental breeding and testing of relevant departments, as long as the variety is pure, combined with the company's most new culture technology, breeding freshwater lobster has considerable economic benefits and rich profits. Put 80 kilograms of shrimp per mu as an example.

Economic benefit analysis

The amount of input per mu is 80kg / mu × 60 / kg = 4800 / mu.

Female-to-male ratio per mu: according to the natural female-male ratio, there are generally more females than males.

Survival rate: general shrimp transport survival rate of 95%, feeding survival rate of 80%.

The number of eggs: 200-600 eggs per female shrimp each time, the natural fertilization rate is 80%, the hatching rate is 40%, the survival rate is only 10% in the natural environment, and the number of eggs laid is 2-3 times a year, which varies according to the natural temperature in different regions.

Commercial shrimp weight: the common individual weight is generally 50-100g, taking the minimum value, the yield per mu is about 400 kg. There are many uncertain factors in yield above (number of female shrimps per mu) (minimum number of eggs per mu) (minimum number of eggs per year) (minimum number of eggs per year) (natural minimum survival rate) (minimum weight of individual). If the simulated ecological environment is good and the bait is sufficient, the unit yield will gradually increase. According to the test results of our company, the lowest yield is 300kg/ mu and the highest yield is 500kg/ mu, but it does not rule out the influence of natural disasters and improper human operation on the yield per mu.

The output value per mu is 400kg × 30 yuan / kg = 12000 yuan / mu.

The above prices refer to Wuhan Dadongmen Market in June 2006, the lobster sales in the peak season is 30 yuan / kg, the normal sales of farmers are different from wild fishing, for every year in late autumn and early winter, the off-season price is expected to be higher. And it does not include the profit distribution of filter-feeding and herbivorous fish in ponds. If the average price of adult fish per mu is more than 6 yuan / kg, the increment per mu is more than 1800 yuan, and the output value per mu is more than 10, 000 yuan.

Input-output ratio

According to the price of 2 yuan / kg of agricultural by-products of bran and bran in 2006, the feed coefficient is 2. The feeding cost of yield per mu is 400 kg × 2 yuan / kg × 2 × 1600 yuan / mu, and the average annual management fee per mu is 500 yuan. The average amount of seed and seedling per mu is 80 kg × 60 yuan / kg = 4800 yuan.

The total investment is 1600 yuan, 500,000 yuan, 4800yuan, 6900 yuan.

Net profit per mu: 12000,1800-6900006900 yuan per mu.

If the off-season sale is carried out by hoarding, the annual price of lobster in autumn and winter is between 24mur40 yuan / kg, and the net profit per mu is between 10, 000 yuan and 20, 000 yuan. If the water surface of farmers is more than 5 mu, the annual income is more than 5-100000 yuan, and its economic benefit is 10 times that of conventional fish culture.
