False spawning

False spawnings can occur several times prior to an actual spawning. Males may release sperm during a false spawning.

False Start
A male Sockeye Salmon (Oncorhynchis nerka) spawning before the female has completed digging the redd. The female is probing with her anal fin as part of this process.

False spawning
A female Coho Salmon (Oncorhynchus kisutch) exits her redd as three sneaker males including a jack (nearest fish, just entering the fray) commence to false spawn. The alpha male is poking over the female's caudal peduncle from her right side in background of shot.

False spawning
Multiple male Coho Salmon (Oncorhynchus kisutch) piled up next to a nearly completed redd pocket following a false spawning. The female has moved off to the side (left side of frame) while the alpha male is downstream (in background) having left the fracas. The heavely spotted fish located above and upstream of the pile-up is a jack.

False spawning
An attempted start to spawning by the female Sockeye Salmon (Oncorhynchus nerka) is preempted by the alpha male charging after a sneaker male.

False spawning end
With at least six males piled up on her redd as a false spawning comes to an end, the female Coho Salmon (Oncorhynchus kisutch) has shifted to a higher position.
