What Is Tea Saponin?
Tea saponin is a kind of glycoside compounds extracted from tea tree seeds. It is a kind of natural surfactant with good performance.
What Is Tea Saponin Used For In Aquaculture?
1.It is a environmentally friendly pond cleaning agent.
The fish poisoning effect of tea saponin has been used in aquaculture as a pond cleaning agent for fish ponds and shrimp ponds to remove the predatory fish. Tea saponin can not only be used as a cleaning agent before breeding. And it can also be used to kill enemy fish in the breeding process. It has been applied to shrimp ponds with hundreds of hectares of coastline in the three major sea areas of the East China Sea, the Yellow Sea and the Bohai Sea, and good results have been achieved.
The fish venom activity of tea saponin increases with the increase of water temperature, so the death rate of fish is also accelerated when the water temperature is high. Tea saponin will be hydrolyzed under alkaline conditions and lose its activity. Seawater is slightly alkaline, so tea saponin will naturally degrade and lose its activity after 48 hours in seawater, so it will not pollute seawater.
According to research, the mechanism of tea saponin's fish poisoning, one is to destroy the fish gill tissue, and the other is to cause hemolysis. The first is to destroy the fish gill tissue, and then the gills enter the microvessels, thereby causing hemolysis, resulting in the death of fish poisoning.
Tea saponin has no effect on prawns that also breathe through gills. The reason is that shrimp gills are cuticle areas developed from cuticles. The epidermis is mainly composed of chitin and protein, which is related to the structure and composition of fish gills. On the other hand, the oxygen-carrying carrier in fish blood is heme, and its core is iron ion, while the oxygen-carrying carrier in shrimp blood is hemocyanin, and its core is copper ion.
Tea saponin only produces hemolysis on red blood cells (including nucleated fish blood, chicken blood and non-nucleated human blood), but has no effect on white blood cells. Therefore, tea saponin has toxic effects on fish, but not on prawns. The mechanism of hemolysis is believed to be caused by changes in the permeability of cholesterol-containing cell membranes caused by tea saponin, initially by destroying the cell membranes, which in turn leads to cytoplasmic extravasation, and finally disintegrates the entire red blood cells.
2.It is a new generation of environmentally friendly aquaculture raw materials.
Tea saponin can promote Shelling of prawns stimulates the growth of prawns. At the same time, it can also kill nematodes and polycondensates attached to crabs, turtles, sea cucumbers, etc., to achieve the purpose of prevention and control. With the gradual prohibition of chemical fish drugs in my country, there are A new generation of environmentally friendly fish medicine formulated with tea saponin will surely be recognized by more and more farmers.
Instructions:
1) Use a mixture of 100 grams of saponin with 20 liters of water, 1 liter per square meter.
2) Increase the water level by 30 cm, add 25 kg/ha to dissolve first, let it stand for 2~3 days, then take out the water, then clean the pond, then fill it up, and start breeding.
3) After the pond has been harvested and cleaned accordingly, dissolve 500 grams of tea saponin in a bathtub with 100 liters of water, or in 5 buckets of 20 liters each, these 500 grams are used for each hectare that will be prepared .
