Embodiment 1

[0016] Silver carp, silver carp and shrimp are mixed in a fish pond of 70 mu. In the early stage of breeding, a large amount of plankton is cultivated with Zhonghua Pei water as bait, and water nutrients are added to the water body every 3 days during the breeding process. Put 50 silver carp per mu, 30 silver carp per mu, 2,000 giant giant rosenbergii per mu, and 20,000 vannamei shrimp per mu. The transparency of the water body is controlled at 28 cm. Feed silver carp with small pellets of extruded feed. In the middle and late stages of the culture stage, some shrimp feed is used for culturing Macrobrachium rosenbergii. The cost of breeding a catty of silver carp is 2 yuan, a catty of silver carp is 1 yuan, a catty of Macrobrachium rosenbergii is 4 yuan, and a catty of vannamei is 2 yuan. The profit per mu is 6,000 yuan.

Embodiment 2

[0018] Silver carp, silver carp, and shrimp are mixed in a 60-acre fish pond. In the early stage of breeding, a large amount of plankton is cultivated with Zhonghuapei water as bait. During the breeding process, water nutrients are added to the water body every 8 days. Put 300 silver carp per mu, 60 silver carp per mu, 5,000 giant giant rosenbergii per mu, and 30,000 vannamei shrimp per mu. The transparency of the water body is controlled between 25 cm and 32 cm. In the middle and late stages of the breeding stage, small-grained extruded feed was used to feed silver carp. Shrimp feed is used to accelerate the growth rate of Macrobrachium rosenbergii and Penaeus vannamei in the middle and late stages of the culture stage. The cost of breeding a catty of silver carp is 2.2 yuan, the cost of a catty of silver carp is about 0.8 yuan, the cost of a catty of Macrobrachium rosenbergii is 4.5 yuan, and the cost of a catty of vannamei is 2.2 yuan. The profit per mu is 7,000 yuan.

Embodiment 3

[0020] Mixed breeding of silver carp, silver carp and shrimp in a fish pond of 80 mu. In the early stage of breeding, a large amount of plankton was cultivated with Zhonghuapei water as bait. During the breeding process, water was put into the water body every 3-8 days Nutrients. Put 200 silver carp per mu, 50 silver carp per mu, 4,000 giant giant rosenbergii per mu, and 25,000 vannamei shrimp per mu. The transparency of the water body is controlled at 30 cm. Feed silver carp with small pellets of extruded feed. In the middle and late stages of the breeding stage, some shrimp feed is regularly put in to accelerate the growth rate of Macrobrachium rosenbergii and Penaeus vannamei. The cost of breeding a catty of silver carp is 2.5 yuan, the cost of a catty of silver carp is about 1.1 yuan, the cost of a catty of Macrobrachium rosenbergii is 4.8 yuan, and the cost of a catty of vannamei is 2.5 yuan. The profit per mu is 8,000 yuan.

Abstract

The invention discloses a spotted silver carp, white silver carp and shrimp intercropping method. The method comprises the steps that spotted silver carps, white silver carps and shrimps are cultured in water in a mixed mode, a large number of plankters are cultured by a water nutrient in the earlier cultivation stage to be used as bait, and the water nutrient is put into the water regularly or irregularly in the cultivation process. According to the spotted silver carp, white silver carp and shrimp intercropping method, due to comprehensive resource utilization, scientific and reasonable allocation and reasonable cultivation density, the cultivation cost is greatly reduced, economic benefits are improved, the an-risk capacity is strong, and sustainable development is achieved; large-scale standardized development is facilitated, and the brand industry with influences is built.

Description

technical field [0001] The invention relates to the field of fish and shrimp farming, in particular to a method for nesting carp, silver carp and shrimp. Background technique [0002] The output of existing large water surface cultured silver carp and silver carp is low, and output value is low, and benefit is not high. The cultivation of silver carp in large water surfaces is mainly to put some low-quality chemical fertilizers and livestock and poultry manure, which pollutes the water quality a lot. There are also some large water surfaces where full-price compound feed is used. Due to the difficulty in fishing and management, the cost of breeding is also high, so the investment is large, the risk is high and the income is low. [0003] Due to the higher and higher requirements for water quality and environment, the high-pollution breeding model is unsustainable, and the use of full-price compound feeds in large-water surface breeding requires large investment, high risks,...
