| Species | Development state | Trait | Primary Data | Secondary Data |
| Oncorhynchus keta | Female | Absolute fecundity | Average 2-3, range 0.9-8.0 | 2.5 thousand eggs |
| Oncorhynchus keta | Spawning conditions | Spawning migration distance | Most chum salmon spawn above the saltwater zone but within 200 km of the sea, although some chum salmon have been reported to migrate up to 322 k upstream to spawn | 200.0 km |
| Oncorhynchus keta | Spawning conditions | Spawning migration period | Chum salmon are the last of the Pacific salmon to return to their natal streams, usually leaving the marine waters in summer and fall to begin their upstream migration | ['July', 'August', 'September', 'October', 'November', 'December'] |
| Oncorhynchus keta | Spawning conditions | Homing | Return to the stream in which they hatched | Present |
| Oncorhynchus keta | Spawning conditions | Spawning period duration | The time spent by adults in freshwater (time of stream entry to death) to be 11 to 18 days | 11.0 weeks |
| Oncorhynchus keta | Spawning conditions | Spawning depth | The average water depth over chum salmon redds in Oregon streams was 30 cm, whilein Washington streams it ranged from 23 to 46 cm | 30.0 m |
| Oncorhynchus keta | Spawning conditions | Spawning substrate | Gravel substrate | Lithophils |
| Oncorhynchus keta | Spawning conditions | Spawning site preparation | The female chum salmon excavates the redd in gravel by turning to one side and rapidly flexing her body, creating water current and removing gravel with the caudal fin | Susbtrate chooser |
| Oncorhynchus keta | Spawning conditions | Mating system | After the depression is complete, the female and dominant male enter the redd and simultaneously extrude eggs and milt. Not all eggs are deposited at one time, as multiple egg pockets are made | No category |
| Oncorhynchus keta | Spawning conditions | Parity | Die after spawning | Semelparous |
