Embodiment 1

[0027] Embodiment 1: a high-yield and high-efficiency fish farming method in Shantang Reservoir, comprising the following steps:

[0028] (1) Breeding location and breeding conditions: The place is located in the Shibei Reservoir Aquaculture Demonstration Base of Liuzhou Tianzhirun Agricultural Development Co., Ltd., located in Xinnantun, Shibeiping Town, Liubei District, Liuzhou City. The Shibei Reservoir is a small (two) type reservoir with a total area of ​​300 mu. The dam was reinforced in the winter of 2013, and then carried out breeding and transformation in the winter of 2014. The bottom of 100 mu of water surface was dug to a depth of 1 meter, and the bottom of the remaining 200 mu of water was excavated. Obstacle removal and leveling treatment, the surrounding slopes are reinforced, and the average water depth is 3.5m. The bottom mud of the reservoir is red loam and pond embankment, sandy mud bottom, with an average thickness of 17cm. The water sources are natural ra...

Embodiment 2

[0048] Embodiment 2: a kind of high-yield and high-efficiency fish farming method in Shantang reservoir, its concrete steps are identical with embodiment 1, and difference is: the overwintering large-scale tilapia fingerling adopts the following method to cultivate:

[0049] ①Construction of overwintering ponds and stocking of fry: select ponds with a size of 3-10 mu as overwintering ponds and build overwintering greenhouses. Light-transmitting film tilapia overwintering greenhouse construction method (Chinese Patent No. ZL201310408941.4) construction, and set up aerators at the same time: equipped with 2 impeller-type aerators (power 1.5KW), 1 waterwheel-type aerator (power 1.5KW), 1 set of microporous aeration facilities (power 3.0KW); then use Guangxi Academy of Fishery Sciences "Guifei No. 1" tilapia fry to stock 5 to 100,000 fish fry with an average size of 2.13cm / Acres are put into overwintering ponds for cultivation and overwintering in greenhouses.

Abstract

The invention relates to a high-yield and high-efficiency fishery breeding method for hilly pond reservoirs. Firstly, breeding conditions are transformed, wherein transformation measures of conductingdredging and deep digging, leveling and obstacle removal on the bottoms in front of dams of the hilly pond reservoirs and reinforcing protection slopes around a reservoir area are adopted, partitionfencing isolation breeding facilities are arranged, anti-escape facilities are reinforced and improved, and ground-cage fishing nets are fixedly arranged; an impeller-type, waterwheel-type and microporous oxygen aeration combined oxygen aeration mode is configured; then two interbreeding modes including the mode of mainly breeding large-sized tilapia mossambica species and interbreeding carps andthe mode of mainly breeding large-sized tilapia mossambica species and interbreeding carps, grass carps and the like are adopted. A new breeding mode is put forward for high-yield and high-efficiencyinterbreeding of the hilly pond reservoirs, and a feasible scheme is put forward for the high-efficiency utilization of the star-studded hilly pond reservoirs. According to the method, the comprehensive mode of breeding condition transformation, species interbreeding, water quality monitoring and product monitoring is adopted, a demonstration mode of a high-yield and high-efficiency ecological breeding technology for the hilly pond reservoirs is put forward through summarization and conclusion, and reference is provided for comprehensive development and utilization, ecological fishery breedingand dual use of water in the hilly pond reservoirs.

Description

technical field [0001] The invention relates to a fishery breeding method, in particular to a high-yield and high-efficiency fishery breeding method for a mountain pond reservoir. Background technique [0002] Shantang Reservoir plays an important role in the development of economy and society, especially in the development of agricultural production in various places. Shantang, as a small or micro water conservancy infrastructure in mountainous areas, has many points and a wide area, that is, it is scattered and unevenly distributed. Most of them were built in the 1960s and 1970s, and played an important role in farmland irrigation and agricultural production in various places. Due to insufficient investment, poor management, and disrepair, its functions and benefits have been greatly reduced. The vast majority of Shantang reservoirs often face conflicts in the management of water conservancy projects, resulting in extensive breeding, and the economic benefits have been lo...
