Embodiment 1

[0025] In a 50-acre pond, silver carp and silver carp are mixed in the water body, and the floating water feed is used to domesticate and feed the silver carp. Fish feed on algae, place net cages in the water body, breed soft-shelled turtles in the net cages, and feed soft-shelled turtles with cultured silver carp.

[0026] Put 500 silver carp per mu, the size of silver carp is 1-3 catties. When the silver carp is raised to 5 catties, it is sold.

[0027] 5,000 silver carp are put in every mu, 4 times a year, and the size of the silver carp is 3-5 cm. The silver carp is raised to about 3 taels, caught and fed to soft-shelled turtles, and 3000 jin of bait fish silver carp is cultivated per mu of water every year. Breeding 500 catties of soft-shelled turtles.

[0028] The cage is 8 meters long, 6 meters wide, and 3 meters deep. The cage is 1 meter above the water surface. The cage uses double-layer nets, with 3 cm mesh for the side net and 1.5 cm mesh for the bottom. And mak...

Embodiment 2

[0034] In the high-efficiency nesting method of silver carp, soft-shelled turtle and silver carp in 60 mu of ponds, silver carp and silver carp are mixed in the water body, domesticated and fed with floating water feed, and the water of the floating water feed Granules with a size of 0.8-1 mm are added to the water body once every 5 days. The silver carp feeds on algae, and a net cage is placed in the water body. The breeding cost of silver carp per catty is 0.5 yuan.

[0035] Put 550 silver carp in every mu, and the specification of described silver carp is 1-3 jin. Raise silver carp to 5-10 catties for sale.

[0036] 5,500 silver carp are released per mu each time, five times a year, and the size of the silver carp is 3-5 cm. If the silver carp is raised to 4 taels, it is caught and fed to soft-shelled turtles, and 3,500 jin of forage fish, silver carp, can be cultivated per mu of water every year.

[0037] Control the transparency of the water body to 20-30 cm.

[0038]...

Embodiment 3

[0043]In March 2013, the inventor used a 100-acre mountain pond to conduct an experiment. Firstly, the pond was cleared, and the miscellaneous fish were removed with tea bran. After 10 days, the algae were cultivated with Chinese culture water, and the transparency was adjusted to 30 cm. Put 300,000 silver carp down, the size is about 3 cm, and then release another 300,000 silver carp seedlings every 45 days, and after 3 days, put 50,000 silver carp with a size of 1.3 catties, and domesticate the silver carp with floating water feed, and after 7 days Eat normally. From May 15th to 25th, we put 40,000 Chinese soft-shelled turtles in 80 net cages. The size is an average weight of 1 catties. Mix and feed Chinese soft-shelled turtles, slowly reduce the feed to 10%, use 1600 catties of Chinese cultured water to cultivate algae every 5 days, and control the transparency of the water body at 20 cm to 30 cm. At the same time, three meals a day were given to the silver carp with 1 mm flo...

Abstract

The invention discloses an efficient intercropping method for spotted silver carps, soft-shelled turtles and silver carps. The efficient intercropping method comprises the following steps: mixing and culturing the spotted silver carps and the silver carps in a water body; domesticating and feeding the spotted silver carps with a water floating feed; feeding a water body nutrient for culturing algae at fixed period or occasionally, wherein the silver carps take the algae as a food; putting a net box into the water body and culturing the soft-shelled turtles in the net box; and feeding the soft-shelled turtles with the cultured silver carps. By the aid of the efficient intercropping method for the spotted silver carps, the soft-shelled turtles and the silver carps, the yield of the spotted silver carps is increased by more than 10 times and the mouth feel is very good; the culture cost of the soft-shelled turtles is obviously reduced and the mouth feel reaches the level of wild soft-shelled turtles; the diseases are obviously reduced. The culture benefits can be greatly improved by the technology. The water body is comprehensively utilized and the benefits are maximized.

Description

technical field [0001] The invention relates to the field of fish breeding, in particular to a high-efficiency nesting method for silver carp, soft-shelled turtle and silver carp. Background technique [0002] The current breeding technology of silver carp has low yield and poor quality, ranging from 200 to 400 jin per mu; it cannot be listed in a balanced and planned manner, and often misses the time when the fish price is good. The fishing cycle is long, each fishing takes more than 10 days, sometimes 60 days in large reservoirs. At present, there are two main types of silver carp farming: one is nest breeding in fish ponds, where 40 to 80 fish are raised per mu, and the output per mu is 200 to 400 catties. Not good, poor taste, low price. The other is large water surface fertilization and water farming. This kind of farming puts 20 to 60 tails per mu, and the yield is very low. Since most of the reservoir lakes with an area of ​​more than 1000 mu cannot be fertilized, ...
