Fisheries Science and Technology Helping Shandong Aquaculture to Increase Production and Increase Efficiency

Shandong Shengcheng Aquatic Products Bureau has made the micro-hole efficient aeration technology of ponds as one of the main technologies for households in science and technology. The leading group of fishery science and technology households in Luancheng City has combined local conditions to promote the increase of production and efficiency of aquaculture in Luancheng through promotion and application. .

Take Anren Township Anqi Fisheries Technology Demonstration Park as an example, the demonstration households in the Park ordered a comparative analysis from the reconstructed microporous aeration type aerator to achieve significant results. He has 7 mu of squid farming water. In the past, he used 2 alternate 1.5 kW and 2 sets of 3 kW impeller aerators to raise and raise them with alternate booting method. After 20 hours of booting, he can meet the needs of pond cultured fish, and the power consumption reaches 90 degrees. The same water surface using microporous aeration aerator, only a 2.2 kilowatt blower, the boot 20 hours can make the pool of dissolved oxygen up to 3.0mg / L, and the upper and lower water temperature uniformity, which will help eat fish growth. Through comparative tests, it is concluded that each turn on machine saves 46 degrees of electrical energy compared with the impeller type aerator. According to the oxygen increase date of 150 days, the electricity charge is 0.55 yuan/degree, and 20 hours of operation per day can save electricity 6900 degrees, and the operating cost can be saved over 3700 yuan. , Energy conservation of more than 50%, and has played a role in inhibiting pathogenic bacteria, activating the pond water quality, maintaining the stability of pond water quality physical and chemical factors, reducing the risk of disease, fishery drugs can reduce the use of more than 50%. The good quality of water caused by high dissolved oxygen can not only increase the stocking density of cultured aquatic organisms, but also increase the aquaculture production, with an average yield of more than 20-30%.

Today, micropore aeration and aeration has been greatly promoted in the Anqi Demonstration Park. The installed area has reached 300 mu. This alone has enabled the entire demonstration park to achieve an increase of 150,000 yuan, which has increased production and efficiency.
