Table 1.
The observed frequencies of diploid and spontaneous triploid salmon according to sampling source and genetic background
Data source | Diploid (n) | Triploid (n) | Total (n) | % Triploid |
---|---|---|---|---|
Samples from farms | ||||
Aqua Gen AS | 1635 | 37 | 1672 | 2.2 |
Salmobreed | 783 | 19 | 802 | 2.4 |
Mowi | 609 | 11 | 620 | 1.8 |
Unknown | 1062 | 15 | 1077 | 1.4 |
Farms total | 4089 | 82 | 4171 | 2.0 |
Samples of recaptured escapees | ||||
Recaptured freshwater | 376 | 4 | 380 | 1.1 |
Recaptured saltwater | 586 | 5 | 591 | 0.8 |
Escapees total | 962 | 9 | 971 | 0.9 |
All samples combined | 5051 | 91 | 5142 | 1.8 |
Note, escapees are not assigned to genetic strain and therefore represent an unquantified mixture of fish from all strains. Fish of “unknown” strain sampled on commercial farms represent an undocumented mixture of all strains.
Samples collected in the period 2007–2014.
