1. Pond construction: Ponds for breeding silver carp require sufficient water resources. What is the maximum area of ​​the pond?

Pond construction for silver carp breeding requires sufficient water source. How much pond area should be controlled? In Guangxi, silver carp and bighead carp are also called standard fish and bighead carp. These two fish have similar appearance and common feeding habits. They are mainly based on floating microorganisms in drinking water. Two of the four most common freshwater fish swim in the water to feed. They are easy to raise, cheap and profitable. The main skill is to disinfect the pond with wax, master the water quality concentration, stocking density, feeding method, daily manual management, etc., which can be said to be a business method that is sure to make money. The technical methods for breeding silver carp and bighead carp are as follows.

Master this good method of breeding silver carp and bighead carp, so that you can breed big fish, bighead carp and long silver carp pond specifications; breeding silver carp and bighead carp requires a large area, preferably more than 2 acres, with a water depth of more than 1.5 meters. Before stocking, use the dry winter to split the bottom of the pond. You can also sprinkle quicklime powder to disinfect pathogens, and before the beginning of spring, add animal manure per acre to mature and ferment, about 500 pounds per acre, and then fill the pond with water, and you can breed fish.

Stocking density; generally, silver carp and bighead carp in aquaculture are mixed with other fish, such as grass carp, herring, tilapia, carp, dace, etc. Therefore, the stocking density of silver carp and bighead carp should be 3 jin/cubic water. If silver carp and bighead carp are mainly supplied with other small fish, it should be 5 jin/cubic water. The number ratio of silver carp and bighead carp can be 6:4 or 7:3. The fish must live in the pond or be pumped in with water. The fish cannot be separated from the fresh water. It is also the best way to add oxygen. If it is a dead pond, the breeding density is low. Dead ponds are not suitable for investment. Only free-range breeding methods can be adopted, and the yield is very small. In addition, too much manure cannot be thrown in, and it is easy for fish to die due to lack of oxygen.

Frying time; People usually raise silver carp and bighead carp around the Qingming Festival, and winter fish can also be released. Both fish are not afraid of cold and can safely overwinter in the south. As long as the water depth is not lacking in oxygen, they can also safely overwinter in the north. Try to enlarge the fry as much as possible, and the weight should be about 100 grams. Feeding and management; Silver carp and bighead carp mainly feed on plankton in the water, and the water quality of the fish pond requires green and fertile. Put as much mature feces as possible, the pond water is fat green, the water is 20-30 cm, and the visibility can also be fed. The feed is usually fed with other fish, and the fish and other excreted feces plankton in the water produce a large number of living streams of microorganisms, silver carp and bighead carp fish need to provide nutrition, and reproduce with circulation. In order to increase the growth rate of silver carp and bighead carp and obtain a higher utilization rate, it is necessary to feed them regularly, fixedly, and quantitatively, and feed them twice a day.

2. Generally, how deep is the water best for fishing silver carp and bighead carp in rivers and ponds in summer and autumn?

Silver carp are all on the surface, so you can start fishing from about one meter. Choose the fishing spot on the leeward side, because there are more floating things here, and there are more food for silver carp and bighead carp here, so you can make fewer nests. There are many videos on fishing for silver carp and bighead carp, you can watch and learn.

3. Teacher! How deep does the water in the outdoor pond need to be? Is there anything I should pay attention to? Thank you!

The water depth of pond aquaculture should not exceed one meter. Of course, it depends on what kind of fish you are raising. If it is circulating water aquaculture, the maximum depth can reach three meters. Pond aquaculture is generally made into a pot bottom shape. The surroundings are high and the middle is the lowest, which is convenient for sewage filtration.

4. How to raise fish in a 10-acre fish pond with a depth of 5 meters

1. Determine the main fish and supplementary fish. The main fish not only account for a large proportion of the stocking volume (weight), but are also the main objects of feeding, fertilization and feeding management. Supplementary fish are farmed fish that play a supporting role. They can make full use of the leftover bait and feces of the main fish and the natural bait in the water to grow well. Determine the main fish and supplementary fish according to market demand, bait source, pond conditions, and fish species source.

2. Polyculture type

(1) The fish farming type mainly focuses on herbivorous fish. This type of farming mainly feeds herbivorous fish with grass, and uses the feces and leftover bait of grass carp and Wuchang fish to raise and breed fish. Since the bait is easy to obtain, the output and economic benefits are high, which is more suitable for the characteristics of fish farming in our city. The types of fish farming mainly based on grass carp and Wuchang fish, grass carp, silver carp and bighead carp, grass carp and black carp, etc.

(2) The type of fish farming that mainly breeds omnivorous fish, such as carp and crucian carp, with grass carp, silver carp and bighead carp as the main fish.

(3) The type of fish farming that mainly relies on filter-feeding fish, such as silver carp and bighead carp, with appropriate co-breeding of fish that feed on organic detritus, such as crucian carp and silver carp.

5. How deep should you fish for bighead carp in the beginning of winter?

This depends on the place, the temperature, the wind, whether it is sunny or cloudy, daytime or nighttime, how deep the water is at the fishing spot, etc. It cannot be generalized. If it is in the south, such as southern Guangdong, you can catch bighead carp at the summer depth during the day, without adjusting the depth. The basic rule is: deep in winter when the temperature drops, shallow in summer (hot days); deep in strong winds, shallow in no wind; deep in the daytime, shallow at night.
