In the video below, a female Chum salmon excavates a nest (redd) during courtship with a male salmon in preparation for eggs and sperm to be deposited

 

In the video below, the dominant male chases off another male after much competition and then returns to the nest (redd). However, the female in the above video gave up on this nest and moved upstream during the nearly half hour that the two males fought. Notice early in the video that the dominant male grabs the caudal peduncle (narrow tail region before the tail fin) of the other male with its hooked jaws that have developed during the transition from adult ocean salmon to an adult spawning salmon
