Juvenile Lake Sturgeon

A researcher holds a juvenile lake sturgeon (Acipenser fulvescens). This ancient order of fish, the Acipenseriformes, is imperiled in all areas of its historic range because of overfishing and human-caused habitat loss and pollution. Sturgeon do not reach maturity until they are 15 or 20 years old, and their young have a very low survival rate
