摘要

TLDRThe video provides a detailed procedure for blood collection from fish, beginning with the preparation of heparinized needles and an anesthetic solution. Fish are anesthetized in the solution, after which blood is collected from the dorsal aorta or posterior cardinal vein using an aspirated tube. Blood glucose levels are measured using a glucometer, and proper post-collection care is given to ensure the fish stabilize and recover.

心得

  • 🧪 Needles prepared with glass capillary.
  • 💧 Anesthetic solution included tricaine.
  • ⏳ Fish soaked in anesthetic for 2 minutes.
  • 🩸 Blood collected from specific sites.
  • 📏 0.3 microliters of blood needed for testing.
  • 🔬 Blood glucose measured using a glucometer.
  • 🕊️ Fish gently returned to water post-collection.
  • 💨 Oxygen supplied until fish recover.

    Needles were prepared with a 1mm outer diameter glass capillary, with tips cut and heparinized using saline. Fish were anesthetized in a solution for two minutes prior to blood collection from the dorsal aorta and posterior Cardinal vein. A glucometer was used to measure blood glucose after collecting a specific volume of blood, followed by care to stop any bleeding and ensuring the fish returned to a clean tank with oxygen supply until recovery.
