Problems solved by technology

However, water resources are scarce at present, and in actual production, there is often no water to replace or the external water source is seriously polluted and is not suitable for aquaculture water; while ultrasonic treatment is too costly, it is not suitable as the best solution for aquaculture water treatment

Embodiment 1

[0014] The method for controlling cyanobacteria in aquaculture water bodies of the present invention includes the following steps:

[0015] (1) In the early stage of seedling release, use high-nitrogen and low-phosphorus fertilizers containing sodium silicate to cultivate the green algae in the cultivation water body to keep the water body suitable fertility;

[0016] (2) In the area north of the Yangtze River from May to July, use beneficial microorganisms with Bacillus as the main ingredient every 10 days, and the dosage is 2.0×10 9 CFU / m 3 , Use microbial methods to suppress the outbreak of cyanobacteria and maintain the dominant advantage of beneficial algae;

[0017] (3) In the area north of the Yangtze River from May to July, 1% Abamectin EC was used, and the dosage was 0.04mL / m 3 , Strictly control the number of zooplankton in the water, especially cladocerans, to prevent large zooplankton from eating beneficial algae.

[0018] After the above steps, the denitrification efficien...

Embodiment 2

[0020] The invention provides a method for controlling cyanobacteria in aquaculture water bodies, including the following steps:

[0021] (1) In the early stage of seedling release, use high-nitrogen and low-phosphorus fertilizer containing sodium silicate to cultivate diatoms in the aquaculture water body to maintain proper fertility;

[0022] (2) In the area north of the Yangtze River from May to July, use beneficial microorganisms with Bacillus as the main ingredient every 8 days, and the dosage is 1.0×10 9 CFU / m 3 , Use microbial methods to inhibit the outbreak of cyanobacteria and maintain the dominant advantage of beneficial algae;

[0023] (3) For the area north of the Yangtze River from May to July, use 1% abamectin EC, and the dosage is 0.02mL / m 3 , Strictly control the number of zooplankton in the water, especially cladocerans, to prevent large zooplankton from eating beneficial algae.

[0024] After the above steps, the nitrogen removal efficiency reaches 91%.

Abstract

The invention belongs to the technical field of aquaculture and particularly relates to a method for controlling cyanobacteria in aquaculture water. The method comprises steps as follows: in the early stage of seedling releasing, a high-nitrogen and low-phosphorous fertilizer containing sodium silicate is used for directionally culturing beneficial algae in the aquaculture water, so that the water has appropriate fertility; beneficial microorganisms mainly comprising bacillus are used every 7-10 days, cyanobacteria propagation is inhibited with a microorganism method, and beneficial algae take the dominant advantage; 1% abamectin missible oil is used, the number of zooplankton in the water is strictly controlled, and the condition that the beneficial algae are eaten by large zooplankton is avoided. According to the principle of ecological balance of the water, the beneficial algae in the water are cultured through the fertilizer, on the basis, propagation of cyanobacteria is inhibited regularly by using a microecological preparation, and the stability and the balance of algal phases and bacterial phases in the aquaculture water are achieved. Besides, the method has the characteristics of low cost, no environment pollution, high growth speed of culture animals, high survival rate, good benefits and the like.

Description

Technical field [0001] The invention belongs to the technical field of aquaculture, and particularly relates to a method for controlling cyanobacteria in aquaculture water bodies. Background technique [0002] Since the outbreak of cyanobacteria in Taihu Lake in Jiangsu and Dianchi Lake in Yunnan in 2007, people’s attention to the hazards of cyanobacteria has gradually increased. The outbreak of cyanobacteria is the result of eutrophication of water bodies and is extremely toxic. The cyanobacteria in cyanobacteria can quickly produce lethal factors and destroy culture. The gill tissue of the subject interferes with the normal progress of its metabolism, paralyses the nerves, and causes death. [0003] The main reasons for the outbreak of cyanobacteria are as follows: ①The imbalance of nitrogen and phosphorus ratio in the water body: most cyanobacteria have nitrogen fixation, and excessive phosphorus will cause cyanobacteria to become the dominant species; ②fast reproduction speed: ...
