Embodiment 1

[0036] Such as figure 1 As shown, the environment-friendly group bream breeding mode schematic diagram provided by the present invention, the specific breeding method is as follows:

[0037] 1. Pond settings

[0038] Choose a 5-mu pond (east-west direction) with a water depth of 2.0 m. The pond is equipped with a feeding machine and an aerator, and 100-150 kg / mu of quicklime is used to clear the pond.

[0039] 2. Set up biological floating bed

[0040] The following positions in the pond are not equipped with biological floating beds: within the aeration range with a radius of about 20 m from the center of the aerator (the aerator is set in the center of the pond); Build a feeding platform and set up a feeding machine). When the water temperature is 24-30 ℃, put the biological floating bed in the test pond. The biological floating bed includes a bracket and a floating bed unit. The material of the bracket is made of wood, bamboo or plastic, and the material of the floating ...

Embodiment 2

[0058] In the present embodiment, adopted biological floating bed provided by the present invention, see figure 2 , image 3 and Figure 4 The biological floating bed includes a bracket 1 and a floating bed unit 2, wherein the floating bed unit 2 is surrounded and fixed by the bracket 1, and the floating bed unit 2 is provided with a plant planting area 3, and the plant planting area 3 is provided with a through hole, and the bracket 1 The vertical height is greater than the vertical height of the floating bed unit 2. The interior of the bracket 1 is hollow, and the inside and outside of the bracket 1 are provided with a grid hole 4 communicating with the inside and outside. The upper surface of the bracket 1 is provided with a plug-in plate 5 that can open or close the grid hole 4 , The upper surface of the bracket 1 is provided with a feeding hole 6 . A water inlet 7 is arranged on one side of the lower end of the bracket 1 , and a water outlet 8 is arranged on the other ...

Abstract

The invention discloses an environment-friendly ecological breeding method for megalobrama amblycephala. The method comprises the steps that firstly, pond setting is arranged, the depth of water in a pond ranges from 1.5 m to 2 m, and sludge at the bottom of the pond does not exceed 25 cm; then, a bio-floating bed is placed in the pond; after the bio-floating bed is put in, biotic communities are bred in the pond in a mixed mode, the megalobrama amblycephala is mainly bred in the pond, and meanwhile other fishes are bred in a mixed mode; then the fishes in the pond are fed with feed, water quality of the pond is regulated and controlled in real time during breeding, and healthy growth of the fishes is guaranteed. According to the method, the bio-floating bed is arranged in the megalobrama amblycephala breeding pond, so that the productivity of periphytic algae is improved, nutritional matter in the breeding water is absorbed, the content of N, P and other nutritive salt in the breeding water is reduced, and the water environment is improved. In addition, aquatic plants growing on the bio-floating bed provide green feed for the megalobrama amblycephala, the feed coefficient is reduced, and the breeding yield is increased.

Description

technical field [0001] The invention relates to an environment-friendly method for ecological cultivation of bream, belonging to the technical field of aquaculture. Background technique [0002] The mode of aquaculture in our country has gradually transitioned from the original extensive farming mode to the intensive farming mode. Intensive farming is a high-density farming system characterized by high input of artificial bait. Compared with the traditional farming model, intensive farming has the advantages of high output per unit of water body, short breeding cycle, and high labor efficiency. However, in this intensive and high-density farming, the amount of residual bait and excrement exceeds the natural decomposition ability of microorganisms in the farming pond, which often breaks the micro-ecological balance of the water body, leading to deterioration of water quality, serious pollution, and even death of aquaculture animals. Mass deaths occur frequently. At present...
