CATDOLL : CATDOLL: How many silver carp should be stocked per acre of water? Any suggestions?

1. How many silver carp should be stocked per acre of water? Any suggestions?

How many silver carp should be stocked per acre of water surface? Any suggestions? First of all, it is certain that this issue cannot be simply generalized. Silver carp and bighead carp can not only be used as cage fish species, but also in some larger water bodies, they are often used as the main fish species. As the main species or intercropping species, the stocking density must be different. In addition, there are many factors that affect the stocking density of silver carp in the hall, such as fish species specifications, water quality conditions, water depth, expected market specifications, our feeding and management level, etc. The following list is based on general conditions only, and orange sweat farmers can adjust it according to actual conditions.

There is a summer bloom for silver carp farming, and about 150,000 silver carp can be raised per acre of water. Monoculture is the main method, and polyculture is not recommended. Generally speaking, aquaculture should be divided into ponds (reduced density) for about a month.

After reaching the size of inches, silver carp can enter the large fish breeding stage. The stocking density at this stage is usually 5000-10000 per fish. Mixed breeding can be advocated at this stage. When mixed stocking, the main fish should account for about 60% of the total stocking. This breeding stage is usually a breeding cycle (from stocking to wintering). Explain why there is such a large adjustment space in this stocking density. Give a simple example. If you want to have a larger pond, put as little as possible. If you want to make the size of the pond smaller, please put it more appropriately. Similarly, if our management is a little more extensive, we should reduce it, manage it more carefully, and put it in a more appropriate place.

Silver carp is rarely raised alone in pond farming. It is mainly used as a breeding variety. Generally speaking, silver carp accounts for about 20% of the total production. Of course, the number of stockings should also account for about 20% of the total stocking, mainly large fish. Taking grass carp as an example, traditional culture believes that "three grass carps and one silver carp, three silver carps and one bighead carp". Fish ponds are mainly farmed with grass carp, and generally there are about 600 grass carps per mu. Therefore, according to this calculation, about 200 silver carps can be raised, of course 150 silver carps and 50 bighead carps. However, due to the significant increase in the per mu yield of fish ponds, coupled with a large amount of artificial feed, the water quality of fish ponds has become more fertile, so the stocking of silver carp should be appropriately increased.

Silver carp is the main stocking species, commonly found in large water bodies such as lakes and reservoirs. Generally speaking, large species of silver carp are mainly raised, with a stocking capacity of about 100 to 300. In short, silver carp prefers deep, wide waters with richer water quality, which is also more suitable for the growth and high yield of silver carp.

As the main fish species, one acre of water surface should be stocked with 300-350 silver carp, which is the most appropriate range. Since silver carp and the other four major carps do not live in the same water layer area, they can be mixed with the four major carps to increase the total fish production per unit area and economic benefits. Silver carp mainly feeds on natural plankton, and plankton must be cultivated during the breeding process. Secondly, it is also necessary to feed some fine feed appropriately, such as refined feed such as yellow dregs mealworms, bloodworms, and earthworms. The feed must be diversified. Feeding a single feed may cause malnutrition to the silver carp.

It is recommended to stock 15-20 jin of silver carp per mu of lobster pond, and it is best if the silver carp fry is about 1 jin. There is a reason for this. The silver carp fry is recommended to be about 1 jin, not too small, because if the silver carp is too small, it is easy to be eaten by crayfish. If the size is too large, the breeding cost will be higher, so the size should be appropriate when stocking.

About 300 fish are more suitable. You must pay attention to the water quality and pH value, and also control the temperature of the hemisphere.

2. How many carps and bighead carps can be raised in 5 mu of land?

Semi-intensive breeding mode: 500 grass carp, 200 carp, 100-150 silver carp, 3 aerators, 0.5-1.5Kw, water level 1M-1.5M. Stocking at 10 degrees water temperature at the beginning of the year, and catching at the end of the year. The grass carp is 4 jin, the carp is 2 jin, and the silver carp is about 4 jin. The total yield per mu is 3000-3500 jin. It is not profitable!

3. How much fish can be raised in an eight-mu fish pond, including grass carp, carp, and silver carp? How much fish can each produce in a year? I hope friends who raise fish can tell me. (Conventional breeding)

Let me analyze this for you. Silver carp eats zooplankton while bighead carp eats phytoplankton. In the pond, phytoplankton is eaten by zooplankton. 10kg of phytoplankton can be exchanged for 1kg of zooplankton. The ratio of silver carp to bighead carp can be decided by you. The recommended stocking size is more than half a catty. The feces of grass carp acts as fertilizer for the water. There are many factors involved, so it is difficult to give an approximate number.

4. Can catfish be raised in the 100-acre Shanquan reservoir?

Customize the breeding plan (especially the species) according to the local market or your own sales channels. It is a pity to only raise silver carp. If you want to raise them well, you must spend a lot of money to adjust the water. It is recommended to semi-intensively raise grazing fish, such as grass carp, carp, etc. (I have never raised catfish, but it should be OK). Raise silver carp by feeding and fertilizing the water, and then adjust the water. You can use lifting nets to catch grazing fish and silver carp, but it must be during the feeding season. Also, you can use lifting nets to clean up wild fish during the feeding season, and wild fish must be cleared, otherwise it will increase the feed coefficient and reduce the output of silver carp.
