Li Fulin, the owner of “Lan Shu Chai Farm†in Shanmen Village, Hualong Town, Panyu District, Guangzhou City, Guangdong Province, used “enzyme bacteria†to raise the fish to a weight of nearly 5 pounds a year, leaving everyone on the scene wondering.
Nutrition, improve feed utilization.
In 2012, when Li Fulin, the owner of “Lan Shu Tsai Farm†in Shanmen Village of Hualong Township, Panyu District, Guangzhou City, Guangdong Province, was learning how to reduce the cost of fish farming, reduce the disease, and turn culture into a profiteer, he learned of an enzyme called “enzyme bacteriaâ€. "Aquatic microbial product can help him solve the above problem.
Under the guidance of Dongguan Kaidewei Company, from March 2012, he used the Sancaixing No. 1 enzyme product to cultivate algae before entering tilapia, and continued to use enzyme bacteria from standard seedlings to cultivation. Products, according to water quality or use No. 1 or No. 2, so that the fish always maintain healthy and rapid growth. Finally, Li Fulin's 24 mu of ponds have a total income of 288,850 yuan for fish, 10,1800 yuan for feed and enzyme bacteria, and 1,87,050 yuan for gross profit. The average income per mu is 7,793 yuan. A total of 67,485 kilograms of feed was used. The pure feed tilapia was 38,900 jin and the grass carp was 7,800 pounds. The feed conversion coefficient was 1.45, and the cost per catty of fish was 2.06 yuan.
The enzyme used by Li Fulin is a kind of aquatic microbiological preparation. According to Cai Gong, senior aquatic engineer of Dongguan Kaidewei Agricultural Technology Co., Ltd., the reason why the enzyme can reduce the feed coefficient, save costs, and reduce fish disease is because of the following: effect:
Direct nutrition
Enzyme bacteria and its fermented material itself are rich in protein, amino acids, vitamins, biological enzymes and various growth factors. Fish can directly eat long meat.
Balanced nutrition
No matter what the recipe is or what the feed is, how much nutrients cannot be balanced or lack will affect the digestion and utilization of feed. For example, the actual utilization rate of the feed currently being cast is generally only 25%, and 75% will be discharged into the water body with the feces. This not only wastes costs but also causes pollution to the water body. Enzyme bacteria and its ferments can reach equilibrium
Complete decomposition
Enzyme bacteria have 24 kinds of beneficial bacteria that can form a complete decomposition chain in nature. From the macromolecular matter to the decomposing to the small molecule material is used by the fish. For example, cellulose and hemicellulose are decomposed into starch or sugar, and then converted into amino acids, fatty acids and other substances for use by fish through the transformation of enzymes. In addition, the enzyme bacteria expel the nutrients discharged with the feces, so that the fish can be reused.
Promote digestion
After the enzyme bacteria are ingested by the fish, some bacteria can settle in the intestinal tract of the fish to form intestinal bacteria, which can help digest feed nutrients and remove harmful residues of the fish.
Conversion utilization
For example, ammonia nitrogen can be converted into enzyme bacteria protein and bacterial components through absorption, so that non-biological or even harmful substances can be converted and utilized.
