Karlista<br>Yes, it is a mixotrophic organism (feeds by ingestion, also by photosynthesis). This is a versatile little bugger. There is a good summary of what is known on wikipedia, see <br><a href="http://en.wikipedia.org/wiki/Akashiwo_sanguinea">http://en.wikipedia.org/wiki/Akashiwo_sanguinea</a><br>
<br>I don't have the answers to all your questions. Not sure when it will die off - your guess is as good as anyone's - but colder water temps and rainy weather should guarantee its demise.<br><br>Take care, Vera<br>

There is another bloom of this critter and our PSP count went from <38 last week to 51 on the 5th.<br>
I counted 2 Alexandrium on week before.<br>
Count on the 5th in WW was 280,000 c/l and in 10 X 466000 c/l ( and I counted to samples just to make sure - and cleaned the slide carefully between.)<br>
Doe the Akashiwo eat everything else?<br>
Has this count been seen before in QMH?<br>
Any idea of what it takes for it to survive this long or what happens when it dies off or when it will die off?<br>
Karlista?<br>
