Larval Sampling
Detailed Description
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.
