A few days ago, the author learned from the Fujian Academy of Agricultural Sciences that China's fish oral vaccine key technology has achieved breakthroughs, and its industrial prospects are broad, which will also bring about the speed of healthy aquaculture.
Recently, the expert group on marine and aquatic diseases from the National Aquatic Animal Pathogen Database and Guangdong, Shanghai and Fujian believes that it has broken through the key technologies of China's fish oral vaccine industrialization, which will transform and upgrade the sea freshwater aquaculture industry and reduce antibacterial chemicals. Use, reduce drug residues, improve food safety, increase farmers' income, and open up broad prospects.
Since 2004, the Institute of Biological Sciences of Fujian Academy of Agricultural Sciences has been dedicated to the innovative exploration of fish clinical medicine, and has created a process for the preparation of vaccines for fish immune stimulating compounds, and obtained three national invention patents.
It is understood that fish immunization usually uses injection, bath and oral inoculation. However, injection has problems that are difficult to operate, time-consuming and labor-intensive, and bath immunization is suitable for the fry stocking stage. Oral immunization is simple and inexpensive. It can overcome the drug resistance caused by antibacterial drugs and drug residues in fish, and help food safety.
The research and application of oral and freshwater fish oral vaccines in China is in its infancy. The breakthrough and promotion of key technologies for fish oral vaccine industrialization will transform and upgrade the healthy aquaculture industry, reduce the use of chemical agents, promote the development of related industries, and increase farmers' income. Open up broad prospects.
Basically there are two types of Diameter Tape Measure, one is Pipe OD Tape Measure Diameter Circumference, another is ID (Inner Diameter) PP Tape Measure
Pipe OD Tape Measure Diameter Circumference
Product Description:
The 2-meter Pipe OD Tape Measure Diameter Circumference is made of reliable material to satisfy precise diameter measuring requirement.The reading for the perimeter, accurate to 1 mm. The tape is double sided with circumference (measures in cm & inch) and diameter (measures in inch & inch) on the either part. Pipe od tape measure adopts fiberglass tape to deliver water and stain proof effect and to ensure that it is of good elasticity for diameter measuring. The retracting mechanism is built in the durable ABS case, thus service life is extended. Wintape provides the diameter tape measure with other patterns and offers customized logo for you.
ID (Inner Diameter) PP Tape Measure
Product Description:
Inner diameter tape measure is made of PP material that is of excellent stress tensile strength and high elasticity. The scale numbers are already been calculated so the tape gives you the result directly without calculating. The practical ID measuring tape can be adopted in various ways such as pipe and container measuring. The double sided inner diameter measuring tape makes number reading easier and more convenient.
