The yield per mu of fish ponds is as high as more than 1000 jin.

The yield per mu of fish culture in fish ponds is generally about 1000 jin, and the high yield can reach about 4000 jin, and different fish species and feeding methods will affect the yield. Pond fish culture generally adopts the mode of mixed culture, and the density of fish culture is determined according to the specifications of fish species, but it should be noted that about 10-15 minutes should be soaked in 4% saline solution before release.

I. yield per mu of fish culture in ponds

1. In general, the yield per mu of fish cultured in ponds is about 1000 jin, but the yield per mu is also different due to different species of fish. When stocking grass carp, silver carp, dace, bighead carp and so on can be properly mixed. Before stocking, all fish species should be soaked and disinfected with 4% salt water solution for about 10-15 minutes.

2. According to the example of 1 mu, the stocking density of grass carp with 250,500g per mu and 1000-1250 grams per mu is 400ind and 300g / mu respectively.

3. The stocking density of mud carp is 1500 per mu, the stocking density is 100g per mu, the stocking density is 100g per mu, the stocking density is 200g bighead carp, and the stocking density is 20 per mu.

4. When stocking, it can be divided into 3 specifications: 1-3 taels, 5-7 taels and up to 1 jin. Fishing can be done about 5 times a year, the average weight is about 3 jin, and the yield per mu can reach more than 4000 jin.

Profit analysis of fish culture in 10 mu fish ponds

According to the unit of one mu of fish ponds and the yield of 800 jin per mu as an example, according to the availability of fertilizer, feed and fish species in rural areas, the yield of silver carp per mu is generally 350 jin and that of eating fish is generally 450 jin.

Details: 50 jin of carp, 1 jin each, 50 jin silver carp, 3.5 jin each, 100 jin crucian carp, 0.8 jin each, 300 jin grass carp, 6 jin silver carp, 300 jin silver carp, 2 jin silver carp, 300 jin silver carp, 2 jin silver carp

The total estimated revenue is 3002.5 yuan, 504.5 yuan, 4505 yuan, 3225 yuan.

The total income of 10 mu fish ponds is 100.3225 yuan = 32250 yuan.

It is estimated that in mu, 3 jin of silver carp, 0.2 jin, 15 fish, 5.5 jin carp, 0.1 jin, 55 carp, 14 jin crucian carp, 0.1 jin, 140 fish, 34 jin silver carp, 0.2 jin, 170 fish, 52.5 jin grass carp, 0.7 jin, 75 fish.

Total input: 37 jin of silver carp, 72 jin of eating fish, a total of 109 jin. At the end of the year, the net weight gain of silver carp was 313 jin, and that of eating fish was 378 jin.

The price of fish seed: calculated according to the price of fish species this year, it is 341.6 yuan, 32.8 yuan, 52.55.5 yuan, 5.55 yuan, 144 yuan, 435.05 yuan.

The input of fish fry in 10 mu fish ponds is: 435.05 yuan * 10 million 4350.5 yuan.

According to the high-quality fertilizers and feed on the market, it is estimated that the annual input of fertilizer is 281.7 jin, 281.7 yuan. The feed is 756jin, 1200 yuan. According to the general rule, it requires 50 yuan per mu for water and electricity and 70 yuan per mu for medicine.

A total of 2036.75 yuan needs to be invested in fish species, feed, fertilizer, water, electricity and medicine per mu, and the return rate of investment in fish culture is about 60%.

10 mu of fish ponds need to be invested: 2036.75 yuan * 100.60 yuan 12220.5 yuan. Through the analysis of the above results, the profit of fish culture in 10 mu fish ponds is 32250-4350.5-12220.5-15679 yuan.
