Title: Larval Sampling
Weighted, small mesh nets (left and right side of the boat attached to winches) are lowered to the bottom of the river near potential spawning sites. After a set period of time, the nets are raised and the contents are hand-picked for any Acipenseriformes (sturgeon and paddlefish) larvae. Samples are preserved for laboratory identification and genetic analysis.
