| Species | Development state | Trait | Primary Data | Secondary Data |
| Oncorhynchus gorbuscha | Spawning conditions | Spawning season | Pacific salmon spawn in fall (though this may be as early as July or as late as February, depending on species and region) whereas the Pacific trout species (formely in the genus Salmo) spawn in spring. | ['February', 'April', 'May', 'June', 'July', 'October', 'November', 'December'] |
| Oncorhynchus gorbuscha | Spawning conditions | Parity | All members of the genus Oncorhynchus(including anadromous and non-anadromous forms) die after spawning, and this is true with three exceptions. Firstn the Pacific trout species, are all iteroparous. Second, male masu salmon (O. masou) that mature in fresh water as parr are capable of surviving, migrating to sea, and spawning in subsequent season, though anadromous males and females are semelparous. Third, under experimental conditions male chinhook salmon can mature as parr, survive spawning, grow, and spawn again the following year, and even a third year. | Iteroparous |
| Oncorhynchus keta | Spawning conditions | Spawning season | Pacific salmon spawn in fall (though this may be as early as July or as late as February, depending on species and region) whereas the Pacific trout species (formely in the genus Salmo) spawn in spring. | ['February', 'April', 'May', 'June', 'July', 'October', 'November', 'December'] |
