The cost and output profit of raising mackerel in ponds

The stocking scheme of fish fingerling is 2000 fish / mu.

Pond conditions: average water depth of aquaculture water body 1.8m~2.2m, silt thickness 15~25cm.

The main fish culture: mackerel.

Set of fish culture: silver carp, silver carp, yellow plate Diao, crucian carp.

1. Mackerel: the specification of fish species is 15kg / mu, and the quantity is 2000 / mu.

2. Silver carp: the size of fish species is 0.3kg / mu, and the quantity is 80 / mu.

3. Silver carp: the specification of fish species is 0.4 to 0.6 jin per mu, and the quantity is 30 fish per mu.

4. Yellow board Diao: fish species specification 10~12cm/ tail (25 tails / jin), quantity per mu 200 tails / mu.

5. Crucian carp: the size of fish species is 0.1 to 0.3 jin per mu, and the quantity is 100 fish per mu.

Fish stocking input: 1074.00 yuan / mu (stocking density 2410 pieces / mu)

1. Mackerel: the specification of fish species is 1525 / jin, with an average of 20 / jin; the quantity put in per mu is 2000 / mu; the price of fish is 6.5yuan / jin (transportation arrival price)

2000 tails / mu / 20 tails / jin = 100jin / mu × 6.5yuan / jin = 650.00 yuan / mu.

2. Silver carp: the size of fish species is 32.5 taels per tail, with an average of 4 taels per mu; the quantity put in per mu is 80 taels per mu; the price of fish fry is 3.0 yuan / jin (transportation arrival price)

80 tails / mu × 4 tails / tail = 32 jin / mu × 3.0 yuan / jin = 96.00 yuan / mu.

3. Silver carp: the specification of fish species is 46.6 taels per tail, with an average of 5 taels per mu; the quantity put in per mu is 30 taels per mu; the price of fish fry is 4.5 yuan / jin (transportation arrival price)

30 tails / mu × 0.5 jin / tail = 15 jin / mu × 4.5 yuan / jin = 68.00 yuan / mu.

4. Yellow board Diao: fish species specification 10~12cm / tail (25 tails / jin); quantity per mu 200 pieces / mu; fish fry price 15.0 yuan / jin (transportation arrival price)

200 tails / mu / 25 tails / jin = 8 jin / mu × 15.0 yuan / jin = 120.00 yuan / mu.

5. Crucian carp: fish species specification 1: 3 taels / tail, average 2 taels / tail; quantity 100 pieces / mu; fish seed price 7.0 yuan / jin (transportation arrival price)

100tails / mu × 2 tails / tail = 20jin / mu × 7.0yuan / jin = 140.00 yuan / mu.

The total of 5 items is: 650,96,68,120,140 = 1074.00 yuan / mu.

Facility, management, labor cost: RMB 2000.00 / mu

1. Pond rental cost: 800.00 yuan / mu.

2. Manpower wage cost: 400.00 yuan / mu.

3. The cost of adding oxygen, adding water, flushing and replenishing water and electricity in the pond is 500.00 yuan / mu.

4. The cost of water improvement, disinfection, insecticidal, disease treatment and medicine in the pond is 300.00 yuan / mu.

The total of 4 items is: 800, 400, 500, 300 = 2000.00 yuan / mu.

Commercial fish output: 13674.00 yuan / mu (cumulative output is about 2810 jin / mu)

1. Mackerel: 2000 / mu x 90% survival rate = 1800 / mu

A, 1800 tails × 40% × 1.0jin / tail = 720jin / mu

720 tails × 1.0jin / tail = 720jin × 5.0yuan / jin = 3600.00 yuan / mu

B, 1800 tails × 60 × 1.3jin / tail = 1080 tails (yield 1404 jin / mu)

1080 tails × 1.3jin / tail = 1404 jin × 5.0yuan / jin = ¥7020.00 yuan / mu

2. Silver carp: 80 tails / mu × 95% survival rate = 76 tails / mu; (yield 304 jin / mu)

76 tails × 4.0jin / tail = 304jin × 2.5kg / jin = 760.00 yuan / mu

3. Silver carp: 30 tails / mu × 95% survival rate = 28 tails / mu; (yield 140 jin / mu)

28 tails × 5.0jin / tail = 140jin × 5.0kg / jin = 700.00 yuan / mu

4. Yellow board Diao: 200 tails / mu x 80% survival rate = 160 tails / mu; (yield 128 jin / mu)

160kg × 0.8jin / tail = 128jin / mu × 8.0yuan / jin = 1024.00 yuan / mu

5. Crucian carp: 100 fish / mu x 95% survival rate = 95 fish / mu; (yield 114 jin / mu)

95 tails × 1.2jin / tail = 114jin / mu × 5.0yuan / jin = 570.00 yuan / mu.

A total of 5 items: 360070207607001024570 = 13674.00 yuan / mu (the total yield is about 2810 jin / mu, including 720 kg / mu, 1404 jin / mu, 444jin / mu, 128jin / mu).

Safety Analysis of Biological load of Fish in Pond from June to November

Since late August, the fish has been caught with a set net, and the biological load of the fish in the pond has been controlled at about 1600-1800 jin. The mackerel is a culture species that is not tolerant to hypoxia, so it is necessary to strengthen pond water quality management, water oxygen content regulation and pest control, and increase the use of oxygen-increasing machinery to prevent hypoxia, flooding ponds and outbreaks of diseases and insect pests.

Feed cost: 7368.00 yuan / mu

1. The mackerel is calculated according to the feed coefficient 1.61.8kg (1.6kg / kg of feed for growing fish), and the feed price is 3400kg / ton (1.7kg / jin).

The feed consumption of mackerel is as follows: 2124 jin fish-100jin fish species = 2024 jin fish × 1.8jin feed / jin fish = 3823 jin feed × 1.8yuan / jin feed = ¥6882.00 yuan / mu.

2. Crucian carp ingested the residual bait at the bottom of the pond and also ate the formula feed. The feed coefficient was calculated according to the feed coefficient of 1.4kg / kg (1.4kg / kg / kg for growing fish), and the feed price was 3400kg / t (1.7g / kg / jin).

Crucian carp feed consumption: 114jin fish-20jin fish species = 94jin fish × 1.6jin feed / jin fish = 150jin feed × 1.6kg feed = ¥270.00 yuan / mu.

3. Yellow plate diggers eat residual ears and algae at the bottom of the water, and also eat part of the fodder. The feed coefficient is 0.8 kg 1.0 for growing fish, and the feed price is 3400 yuan per ton (1.7 yuan 1.8 yuan per jin).

Yellow plate Diao consumes feed: 128jin fish-8jin fish seed = 120jin fish × 1.0kg feed / jin fish = 120jin feed × 1.8yuan / jin feed = ¥216.00 / mu.

The total consumption of feed for 3 items is 688227021607368.00 yuan / mu.

Comprehensive cost per mu: RMB 10442.00 / mu

Fish species 1074 + facilities, management, manpower 2000 + feed 7368 = 10442.00 yuan / mu

Comprehensive benefit per mu: RMB 3232.00 / mu

The total output is 13674 yuan / mu-the total input is 10442 yuan / mu = 3232.00 yuan / mu.
