Atlantic Salmon Smolt Data from the Margaree River, Nova Scotia

PURPOSE: To estimate the abundance of Atlantic salmon smolts in the Margaree River watershed.

DESCRIPTION: A rotary screw trap (RST; also known as a smolt wheel) is used to perform a capture-mark-recapture experiment on the main stem of the Margaree River. Smolts are captured at the wheel, a subset are tagged (max 200 individuals daily) and released upriver. Individuals not tagged are enumerated and released at the wheel. A fraction of tagged individuals are recaptured at the wheel. Trap efficiency and smolt abundance can be calculated from this data.

USE LIMITATION: To ensure scientific integrity and appropriate use of the data, we would encourage you to contact the data custodian.
