The Zhuhai Aquatic Technology Promotion Station of Guangdong Province had previously applied the enzyme fermentation technology test in the fish and shrimp polyculture model of the non-pollution breeding base of Tilapia tilapia and achieved success in that year. Two experimental ponds increased shrimp harvest by 1,200 yuan per mu, while the control ponds had no income.
Lin Youxing, a farmer, introduced that he had adopted a fish-patch polyculture model for 6 years. Before using water for fermentation of enzymes, the cost of using other water-transfer products per mu was over 1,000 yuan per year. However, the survival rate of shrimp is still low. . After the use of enzyme bacteria products to divert water, not only the water transfer costs are saved by 2/3, but also the survival rate of shrimps is significantly improved, and the shrimp is released 15-20 days earlier. Tilapia has fewer diseases, rapid growth, and high efficiency.
Enzyme bacteria transfer water polyculture effect is good
In the polyculture model of tilapia and Penaeus vannamei, the survival rate of the shrimp is often low, the yield is low, and the success rate of breeding is low. Today, through the promotion and application of enzyme bacteria technology, the success rate of fish and shrimp polyculture has been greatly improved.
