Embodiment 1

[0047] 1. Constructing a pond culture system for crucian carp with attachment substrate ecology

[0048] In December 2013, a pond of 8.3 mu was selected (east-west orientation, length 92m, width 60m), the water depth was 2.0m, the pond was equipped with a feeding machine and an aerator, and 100-150kg / mu of quicklime was used to clear the pond.

[0049] The following positions in the pond do not set up attachment bases: within the range of oxygenation with a radius of about 15m from the center of the aerator (set up the aerator in the center of the pond); Feeding platform, set feeding machine); 14m from the east side of the pond, and within 10m from the south and north sides.

[0050] Insert poles and pile at the corresponding positions on the south and north sides of the pond, and drive 28 piles on each side with an interval of 1.0m; pull iron wires between the north and south piles, with a total of 28 rows of iron wires (17 rows and 11 rows on the east and west sides of the a...

Embodiment 2

[0059] 1. Constructing a pond culture system for crucian carp with attachment substrate ecology

[0060] In January 2014, a pond of 10 mu was selected (east-west orientation, length 103m, width 65m), the water depth was 2.0m, the pond was equipped with a feeding machine and an aerator, and 100-150 kg / mu of quicklime was used to clear the pond.

[0061] The following locations in the pond are not provided with attachment bases: within the aeration range with a radius of about 20m from the aerator as the center (the aerator is set in the center of the pond); Feeding platform, set feeding machine); within 10m from the east, south and north sides of the pond.

[0062] Insert poles and pile at the corresponding positions on the south and north sides of the pond, and drive 25 piles on each side with an interval of 1.3m; pull up iron wires between the north and south piles, with a total of 25 rows of wires (16 rows on the east and west sides of the aerator and 9 rows); the iron wire...

Embodiment 3

[0071] 1. Constructing a pond culture system for crucian carp with attachment substrate ecology

[0072] In January 2014, a 7-acre pond (east-west orientation, length 83m, width 56m) was selected, with a water depth of 2.2m. The pond was equipped with a feeding machine and an aerator, and 100-150kg / mu of quicklime was used to clear the pond.

[0073] The following locations in the pond are not provided with attachment bases: within the range of oxygenation with a radius of about 15m centered on the aerator (set up the aerator in the center of the pond); Feeding platform, set feeding machine); 10m from the west side of the pond, and within 11m from the south and north sides.

[0074] Insert poles and pile at the corresponding positions on the south and north sides of the pond, and drive 32 piles on each side, with an interval of 1m; pull iron wires between the north and south piles, with a total of 32 rows of wires (16 rows on the east and west sides of the aerator). 20cm away...

Abstract

The invention discloses a substrate ecological crucian pond culturing method and relates to the technical field of aquatic product culture. The method comprises the following steps of building a substrate ecological crucian pond culturing system, breeding crucian, managing culturing and catching fish products, wherein the first step comprises substeps of pond preparation, substrate set, pond interc-breeding group formation. Compared with a traditional culturing mode, life habits of cultured fishes are employed and substrate is arranged in the pond to build substrate ecological crucian pond culturing method; a problem of water quality degradation due to high density of culture can be effectively controlled, so crucian can be less attacked by diseases; inter-breeding fish substrate foods can be provided by the substrate, so cost is reduced; benefits can be increased for inter-breeding fish products; greener and healthier ecological breeding model can be achieved; and high quality of crucian and Plagiognathops microlepis can be realized.

Description

technical field [0001] The present invention relates to the technical field of aquaculture, and in particular to a culture method for crucian carp in a substratum ecology. Background technique [0002] Crucian carp is one of the freshwater cultured fishes with steady and continuous growth in aquaculture production. Today, crucian carp is mainly cultured in two high-density cultures: monoculture of crucian carp and mixed culture of crucian carp (according to the ratio of 80:20, mainly crucian carp, mixed with a small amount of silver carp and bighead carp). Farming mode. High-density breeding of crucian carp leads to deterioration of water quality and frequent occurrence of diseases, which are the main problems restricting the development of crucian carp breeding industry. [0003] There are still many deficiencies in the existing crucian carp farming model: [0004] 1. The area of ​​the breeding pond is large, and the input cost is high, which increases the risk of breedin...
