<p class=MsoNormal>It appears that there is a possible bloom of <i>Cochlodinium</i>
sp. in Sinclair Inlet (central Puget Sound, near Bremerton) presently, based on
sampling information provided by American Gold Seafoods. Also there
are some <i>Heterosigma</i> cells in the water of North Puget Sound, north of
Cypress Island. Presently the tides are extreme which may help
attenuate blooms, but if the warm weather continues, as predicted, by next week
there could be significant blooms of these or other HABs. <o:p></o:p></p>

<p class=MsoNormal>The gymnodinioid (unarmored) dinoflagellate<i> Cochlodinium cf.
polykrikoides</i> is a serious wild and farmed fish killer and has been known
to occur in British Columbia where it killed farmed fish a few years ago.
Nicky Haigh reports that it is often seen in mid to late July in the NE
Vancouver Island area and on the West coast of Vancouver Island from mid-August
to October. It is widely geographically distributed and is notorious for
killing fish in Japan and Korea and seems to have expanded throughout the
western Pacific in recent years. It was apparently responsible for the
recent massive blooms and fish kills of the Persian (Arabian) Gulf too. Nicky
reports that at 2000 cells per ml it will kill fish in British Columbia but
that the identity is not exactly known for this region. See <a
href="http://www.pices.int/publications/presentations/PICES_15/Ann15_W4/W4_Matsuoka.pdf">http://www.pices.int/publications/presentations/PICES_15/Ann15_W4/W4_Matsuoka.pdf</a>
for an informative presentation from a recent PICES meeting on this genus. <o:p></o:p></p>

<p class=MsoNormal>Because of these observations I suggest that those of you who
can, keep an eye on your local waters for unusual occurrences and blooms and
share your observations with all of us on SoundHAB. As we learned
in 2006, bloom succession sometimes involves multiple harmful species and there
is a need to react rapidly to characterize these events. There is
also a need to collect specimens for positive identification, if possible. <o:p></o:p></p>
