Fish Need to Move! Learning About Fish Migration - American paddlefish

I have long been used by humans as a delicious source of meat. My eggs also have been sold as caviar, a gourmet food for people. Caviar is extremely valuable, which can make us the target of illegal fishing.  Our populations are declining dramatically because of loss of habitat, overfishing and barriers to fish movement, like dams. The construction of dams and reservoirs decreases water flow in the river and interrupts our life

cycle. We need large amounts of flowing water in order to spawn or reproduce.
