Species Development state Trait Primary Data Secondary Data
Oncorhynchus keta Spawning conditions Nycthemeral period of oviposition Chum salmon seem capable of spanwing at any time during the day or night. Activty seems to be associated more closely with time to next spawning than with the light cycle, i.e. there is a repeated sequence of events leading to oviposition, and initiation of each sequences seems independent of the light cycle. Ambiguous
Oncorhynchus keta Spawning conditions Spawning site preparation Spawning behavior in both chum salmon and rainbow trout consists of a combination of nest building by the female and courtship display by the male, leading to deposition of fertilized eggs in the nest [more details provided in the article] No category
Oncorhynchus mykiss Spawning conditions Spawning site preparation Spawning behavior in both chum salmon and rainbow trout consists of a combination of nest building by the female and courtship display by the male, leading to deposition of fertilized eggs in the nest [more details provided in the article] No category
Oncorhynchus keta Spawning conditions Spawning water type The ability of chum salmon and rainbow trout to detect upwellling currents, and the reduction in digging variability associated with development of the nest, suggest that the current pattern around the nest provides important locative information for the females. Flowing or turbulent water
