Fish Tagging Services

Biomark employees have tagged more than 1 million fish for hatcheries and environmental studies that monitor fish movement. Fish are tagged using the body cavity technique with single use needles to reduce the risk of disease transmission.

The size of the project determines the equipment used and size of the crew. Given our experience with tagging, we are very efficient and effective in our process. For example, a crew of four can tag 5,000 fish in one day.
