Culture method for tilapia breeding based on bio-flocculation technology

Abstract

The invention discloses a culture method for tilapia breeding based on a bio-flocculation technology. According to the bio-flocculation technology, through assimilation and absorption of microbial communities to inorganic nitrogen in aquaculture water, cordate houttuynia in the floating bed can absorb and assimilate excess nitrogen, phosphorus and organic matter in the pond culture process to purify the water in the pond. The formed bio-flocculent can be used as feed protein, so that secondary utilization of bait protein is realized, the growth of tilapia is promoted, and the utilization efficiency of bait is improved. In addition, cordate houttuynia as a medicinal plant can provide food for tilapia in the process of culture, which is conductive to the improvement of the immune performanceof the fish body. By combining the advantages of the bio-flocculation technology and the cordate houttuynia floating bed technology, an obvious regulation effect is achieved on the water quality of pond culture, and water self-purification is promoted. Moreover, the non-specific immunity of tilapia can be obviously improved to a certain extent, and the yield of tilapia can be increased.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to a method for cultivating tilapia based on biofloc technology. Background technique [0002] With the rapid development of my country's tilapia farming industry, farming models are becoming more and more diverse. In 2012, the adult fish breeding area in the main tilapia producing areas in my country was about 1466.67 km 2 , of which ponds accounted for 83%, and reservoirs accounted for 8%. At present, pond aquaculture mostly adopts high-density, high feeding rate, and high water consumption to obtain high profits. This not only pollutes and wastes water resources, but also increases the incidence of diseases. It has become a sustainable development of pond aquaculture in my country. biggest obstacle. [0003] Ecological floating bed technology is a relatively new in-situ restoration and control technology for water bodies. Using ecological floating bed technology, aquatic p...
