What we know about homing

• Capable of precise navigation at multiple spatial scales

• Open ocean to freshwater
• Within freshwater system
• Site of incubation

• Homing confers an evolutionary advantage, just as migration does

• Allows for local adaptation
• Improves likelihood of successful reproduction
• Evident in many species – mountain whitefish, northern pikeminnow, largescale suckers

Notes:

Salmon are renowned for homing and migration. From 1940-1999 >3000 adults passed Roza only 4 times. Since 2000 it has happened 8 times.
