| Bloom event dates (yyyy/mm/dd): | ||
| Quarantine levels dates (yyyy/mm/dd): | First detection: 2015-04-29, | |
| Additional date-related information: | Bloom had two peaks - May-June and August | |
| Causative organism known: | Yes | |
| Causative Species/Genus: |
Pseudo-nitzschia sp.
(unknown cells/L)
ID of P. australis being causative species for DA toxin was not able to be confirmed. Several different Pseudo-nitzschia species observed |
|
| Co-Ocurring Species/Genus: | ||
| Chlorophyll concentration, if known: | µg/l | |
| Additional bloom information: | The bloom continued and expanded along the entire coastline, appearing to peak around June 17, 2015. The entire west coast was closed throughout June. Levels were decreasing by June 29th. Domoic acid levels in mussels were 10X less than those reported in the US in razor clams probably due to the rapid depuration rates in mussels compared to razor clams which are the standard test organisms for CFIA in Canada. | |
