Embodiment 1

[0024] The inventor puts sweet-scented osmanthus fish, silver carp, silver carp, and dace in the net cage at the same time, and feeds the floating water feed twice a day, puts in nutrients once every 5 days, throws biological bacteria once every 8 days, and kills them every 13 days. Insects once, disinfected every 18 days. Put 500 silver carp per mu. The size of silver carp is 0.8-1.2 catties. Through the cultivation of silver carp, on the one hand, it has obtained good economic benefits, and on the other hand, it has provided a large amount of organic matter and bait to the water body. , put 2 million dace fry per acre to cultivate, use dace as bait for osmanthus fish, and stock 500 osmanthus fingerlings per mu, the size of osmanthus fish is 6-8 cm. Then put 50 silver carp per mu. The size of silver carp is 11-13 centimeters, and they are used to eat macromolecular algae to regulate water quality. And install an impeller type aerator every 50 mu in the water. The annual outp...

Embodiment 2

[0026] Inventor puts silver carp into net cage simultaneously, drops dace, sweet-scented osmanthus fish, silver carp in large water surface. Feed silver carp with floating feed 3 times a day, add nutrients once every 7 days, put biological bacteria once every 12 days, kill insects once every 16 days, and disinfect once every 22 days. Put 800 silver carp per mu. The size of silver carp is 0.8-1.2 catties. Through the cultivation of silver carp, on the one hand, it has obtained good economic benefits, and on the other hand, it has provided a large amount of organic matter and bait to the water body. , put 2.1 million dace fry per mu to cultivate, use dace as the bait of sweet-scented osmanthus fish, and stock 800 sweet-scented osmanthus fish fingerlings per mu, the size of sweet-scented osmanthus fish is 6-8 cm. Then put 45 silver carp per mu. The size of silver carp is 11-13 centimeters, and they are used to eat macromolecular algae to regulate water quality. And install an imp...

Embodiment 3

[0028] In April 2014, the inventor used an 80-acre fish pond to conduct experiments. First, the fish pond was cleared, and then the water was cultivated, and 160 million dace fry were released in three times, once every 15 days. Eight days after dace fry, 50,000 osmanthus fingerlings were released at one time, and the size of the osmanthus fingerlings was 6 cm. In another 15 days, 40,000 silver carp with an average size of 1.2 catties and 4,000 silver carp with an average size of 13 cm were released. Afterwards, the floating feed was fed three times a day. A total of 100 tons of floating feed was fed in a year. Water nutrients were added every 7 days. A total of 12 tons of water nutrients were used in a year. Bacillus was used to improve water quality every 10 days. A total of 500 catties were used in one year, and the insects were killed every half a month and disinfected every 20 days. Equipped with 4 impeller aerators. The monthly electricity consumption is about 1,500 yu...

Abstract

The invention discloses an efficient mixed culture method for mandarin fish, spotted silver carp, silver carp and dace. The method comprises the following steps: performing mixed breeding on the mandarin fish, the spotted silver carp, the silver carp and the dace; feeding floating feedstuff regularly or irregularly; feeding water nutrients and biological bacteria regularly or irregularly; killing insects regularly or irregularly; sterilizing regularly or irregularly. The efficient mixed culture method is scientific and reasonable; by virtue of the efficient mixed culture method, culture risks are reduced, the fish quality is improved, the mandarin fish culture cost is 4-5Yuan per jin and is reduced by about 5 times in comparison with that in the prior art, and the spotted silver carp culture yield is greatly increased; the flesh quality of the spotted silver carp is improved, so that the spotted silver carp is more fresh and delicious in taste and free from off flavor; the problem that the spotted silver carp cannot conveniently appear on the market at any time is solved, the spotted silver carp yield is greatly improved, and the spotted silver carp can appear on the market at any time according to the market quotation.

Description

technical field [0001] The invention relates to a fish breeding method, in particular to a high-efficiency nested breeding method for sweet-scented osmanthus carp, silver carp, silver carp and dace. Background technique [0002] Due to the rising rent of fish ponds and the increasing pollution of water quality, the cost of breeding is high and the benefit is low, and the benefit is less than 20%. The breeding method is unscientific and there is no comprehensive utilization of waste into treasure. It is about 21 yuan per catty, while our breeding cost is 4 to 5 yuan per catty, which is about 5 times lower. There are many diseases. Due to the high density of sweet-scented osmanthus fish breeding and poor water quality, a large number of diseases are caused, and sometimes the whole army will be wiped out. Due to the poor water quality of the cultured sweet-scented osmanthus fish, more and more medicines, and more and more drug residues, the meat quality of the sweet-scented os...
