Several models for efficient cultivation of ponds

According to the experience of pond culture in Baoyinghu Farm, Jinhu County, Jiangsu Province, the author proposed several highly efficient breeding models for reference.

One, fish and polyculture

Mainly fish, set turtles. Acres stocking species 100 kg; sets of 60-80 cubs, specifications 150-200 grams each. Per mu produce 400-500 kilograms of fish, 30-40 kilograms of glutinous rice, and 2000-2400 yuan of profit.

Second, carp polyculture

The main crickets are turtles, which include oysters, clams, grass carp and other fish. A total of 600-700 cubs are stocked on a mu, with specifications of 160-180 g/body; 25 kg of fish species. The yield per mu is 140-160 kilograms, the adult fish is 100 kilograms, and the profit is 2,500-3,000 yuan.

Third, fish and crab polyculture

Mainly fish, sets up crabs. Acres stocking species 75 kg; 200 young crabs, specifications 160-200 per kilogram. 300 kg of fish per mu, 20 kg of crabs, and 1800-2200 yuan of profit.

Fourth, the pond refined crab

There are 700 sticks of crabs in the mu, with specifications of 100-160 per kilogram. The yield of 40 kg per mu crab, the rate of recovery of 70%, the survival rate of 75%, 70% of the crab product rate, mu profit of 2600 to 3,000 yuan.

Fifth, fish and shrimp polyculture

Mainly fish, set up the green shrimp. Acres put 75 kilograms of fingerlings; shrimp l-1.5 million tails, specification 3000-4000 tails per kilogram, or 0.5-l kilograms. 300 kg of fish per mu, 20 kg of shrimp, and 1200-1500 yuan of profit.

Six, fish, shrimp, crab polyculture

25 kg of mu fish; 1 kg of spawning shrimp; young crabs

300, specifications 200-300 per kilogram. Per mu produce 100 kilograms of fish, 10 kilograms of shrimp, 25 kilograms of crabs, and profit of 2500-2800 yuan.

VII. The main breeding pond

A variety of 160-180 kilograms of heterotrophic silver carp was introduced, with a specification of 14-18 tails per kilogram; 400-450 kilograms of polyculture silver oysters, 1800-2000 yuan in profits.

VIII Pond fish and pig combination

Each 3-5 mu of breeding pigs, a pig producing 2,500 kg of pig manure, can produce 80-100 kg of fish, reducing the input of concentrate feed. Mu profit 1600-1800 yuan.

Nine, pond fish grass combination

Each mu of pond surface, with 0.3 acres of grass, planted fish like food of Sudan grass, ryegrass, bitter herbs and so on. One mu of pasture grass fresh grass yield up to 0.5-0.6 million kilograms, can produce 350-450 kilograms of fresh fish. Mu profit from 1800 to 2,000 yuan.

+, pond cultivation of crab species

Mu put into the late crab (larvae) 0.5-l kg. Mu production young crabs l. 5-30 thousand, mu profits above 10,000 yuan.
