Species | Development state | Trait | Primary Data | Secondary Data |
Oncorhynchus gorbuscha | Egg | Temperature for incubation | The embryos were incubated at 15°C for 10 days until epiloby was complete, then the temperature was lowered 0.5°C every 2 days until a 9°C incubation temperature was obtained, and the embryos were maintained at 9°C until hatching | 15.0 °C |
Oncorhynchus gorbuscha | Larvae | Temperature during larval development | Once hatching was complete, the temperature in the incubator was increased 0.5°C every 2 days until a target of 13.5°C was reached, and then the alevins were maintained at this temperature until 50% had the yolk sac completely covered wtih chromatophores | 0.5 °C |
Oncorhynchus keta | Egg | Egg size after water-hardening | Water hardened diameter means range between different populations from 7.89 to 8.59 | 7.89 mm |
Oncorhynchus keta | Egg | Incubation time | In Central coast: time to 50% hatching 186.8 [At 2.2°C], 124.5 [4.1°C] and 69.3 [8.1°C] | 50.0 days |
Oncorhynchus keta | Egg | Temperature for incubation | Highest embryo survival rates for most stocks were recorded at an incubation temperature of 8°C, while the lowest were at 2°C | 8.0 °C |
Oncorhynchus keta | Larvae | Initial larval size | Alevins hatchings at 8°C were the longest 22.9 mm, those at 4°C slightly shorter (22.5), and those at 12°C (22.2), and 2°C (20.6) | 22.9 mm |
Oncorhynchus keta | Larvae | Temperature during larval development | As with the embryo, the highest alevin survival rates were recorded at an incubation temperature of 8°C, while the lowest were recorded at 2°C | 8.0 °C |
Oncorhynchus keta | Larvae | Full yolk-sac resorption | In Central coast: time to 50% emergence 327.6-186.8 [At 2.2°C], 204.1-124.5 [4.1°C] and 132.3-69.3 [8.1°C] | 257.2 °C * day |
Oncorhynchus keta | Female | Age at sexual maturity | Range from 2 to 6 yr, with 3 and 4 yr being the dominant ages of maturity [Both sex] | 2.0 year |
Oncorhynchus keta | Female | Length at sexual maturity | In Central coast, for females, mean size of 49-53.5 [Age 3], 53.1-59 [Age 4] and 63.2 [Age 5] | 51.25 cm |
Oncorhynchus keta | Male | Age at sexual maturity | Range from 2 to 6 yr, with 3 and 4 yr being the dominant ages of maturity [Both sex] | 2.0 years |
Oncorhynchus keta | Male | Length at sexual maturity | In Central coast, for males, mean size of 49.2-56.7 [Age 3], 53.8-61.3 [Age 4] and 66.8 [Age 5] | 52.95 cm |
Oncorhynchus keta | Male | Male sexual dimorphism | Males had larger heads, thicker caudal peduncles, and larger dorsal fins than females, but females had larger anal fins than males | Absent |
Oncorhynchus keta | Spawning conditions | Spawning migration distance | Habitat ranging from tidal areas, to small streams only a few kilometres in length, to the mainstreams of large rivers over 200 km from salt water | 200.0 km |
Oncorhynchus keta | Spawning conditions | Homing | Return to spawn to their natal streams | Present |
Oncorhynchus keta | Spawning conditions | Spawning season | As early as July in northern and central areas of British Columbia and as late as January in the southern region | ['January', 'July'] |
Oncorhynchus keta | Spawning conditions | Spawning water type | Habitat ranging from tidal areas, to small streams only a few kilometres in length, to the mainstreams of large rivers over 200 km from salt water | No category |
