Evaluation of the Reproductive Success of Lake Sturgeon at the Drummondville Spawning Ground in Spring 2017
The evaluation of reproductive success is based on the estimation of the number of eggs deposited on the spawning ground in relation to the number of larvae that have drifted.
First, we defined the area and the spawning period and captured eggs using an egg sensor and a drift net. Then, we carried out a sturgeon capture-mark-recapture campaign to estimate the size of the spawning contingent. Finally, we caught drifting larvae.
