Pond fish tips:

1, thoroughly clean the pond disinfection, a full bottom fertilizer. Before the fish species in the pond, to dredge the injection and drainage channels, clear the pond too much silt. Water depth of 20 cm, per mu fish pond with 100 kg of lime with water disinfection, kill pests, germs and microorganisms, and then apply 500 kg of rotted human and animal manure as a bottom fertilizer. Then store water 2 to 2.5 meters deep, to be 1 week after the disappearance of the drug before releasing the fish.

2, increase the stocking specifications, put "catty fish species". Large specification fish species have a high survival rate, and can ensure that the commercial specifications of the pumping out of the pond. Therefore, the best stocking specifications are 200 to 400 grams of grass carp, bighead carp 100 to 300 grams, carp 50 to 150 grams.

3, reasonable with mixed farming, the implementation of three-dimensional fish. In order to make full use of the water space and natural bait, must be on, in, under the water layer of three-dimensional farming bighead carp, tilapia and other "fertilizer fish" and grass, carp, pomfrets and other "eating fish". Each mu stocking "catty two fish species" 1200 ~ 1500, of which grass carp accounted for 40%, bighead carp accounted for 40%, carp, crucian carp, pomfrets, tilapia accounted for 20%, the total stocking per mu of about 150 kilograms.

4, feeding mixed feed, adhere to the fine management. According to the physiology of fish, life needs, the use of wheat bran, rice bran, soybean cake flour, lees, minerals, vitamins and fish medicine, made of mixed (mixed) feed feeding, improve the efficiency of feeding. Feed 1500 kilograms per mu per year. At the same time, planting ryegrass, sudangrass, salvage fine green peppermint, duckweed feeding grass carp, fed 2 to 3 times a day. 5, timely and skillful fertilizer, cultivate natural bait. When the temperature is low, it is advisable to fertilize the water, cultivate the plankton suitable for "fertilized fish" to feed on, and promote the rapid growth of bighead carp. Apply fertilizer every 2-3 days, 100-150 kilograms of well-rotted human and animal manure per mu each time. In summer, the temperature rises, the application of farmyard fertilizer is easy to flood the pool, can be changed to the application of chemical fertilizer, every 5 to 7 days to apply, each time per mu of chemical fertilizer 2.5 to 5 kilograms.　　The company's website is a good place to find out more about the company's products and services.

6, set of specification fish species, phased capture large stay small. Scientific design of fish stocking, set of stocking, between the number of times and the number of fishing, the implementation of rotating catch and release, three times a year to catch the big stay small, can start catching 500 to 600 kilograms, to achieve a balanced listing, the remaining fish after the fall and out of the pond. the end of July began to set of 6 to 10 cm of small fish species, for the second year to cultivate the large size of the fish in preparation for the species.

7. Sprinkle drugs in turn, timely prevention and treatment of fish disease. High-temperature period every half-month per mu with lime 10 kilograms, or 90% crystal trichlorfon 250-350 grams of mixing slurry splashing, while in the fish floating bait table hanging bleach or copper sulfate, ferrous sulfate medicine basket, food field disinfection. Grass carp enteritis season, every 100 kilograms of grass carp with 0.5 kilograms of garlic mixed with bait feeding, feeding for 3 to 6 days, to prevent grass carp enteritis disease.

Pond conditions

High-yield ponds are generally about 10 acres in area, with a depth of water of about 2.5 meters. Because of the high yield pond plankton and suspended organic matter rich, photosynthetic effective radiation is generally rarely able to penetrate to the water layer below 0.5 meters, should be mechanically oxygenated or refilled with more dissolved oxygen in the new water, in order to improve the dissolved oxygen conditions near the bottom of the water, to improve the amount of stocking and production. The soil quality of the pond is generally sandy loam. Water quality requires slightly alkaline (pH 7-8.5), hardness 5-8, transparency of about 30 cm, dissolved oxygen 3-6 mg / liter. Before stocking should be removed from the pool of excessive silt, repair embankment and lime and other drugs to kill pests and diseases.
