Review: Abdel Rahman El Gamal (Founder of the website)
A Passive Integrated Transponders “PIT” tag is biologically inert small glass-encapsulated electronic microchip with a standard length that ranges between 10 and 14 millimeters and about 2 millimeters in diameter. Because the PIT is inert and has no internal battery, it remains dormant until its circuitry is activated by a close-range, electromagnetic field generated by the reader (scanner) where the unique alphanumeric code is received from the tag and displayed on the scanner. The PIT is injected and pushed in the body cavity of tagged fish. Because the PIT tags can last through the life cycle of tagged fish, its use is justified in breeding programs. The tagged fingerlings as shown in the video are anesthetized. As shown in the video, potassium permanganate has been used to disinfect the needle and to clean the wound.
