00:00For months, South Australians have been witnessing the devastation of the ongoing algal bloom,
00:08with researchers across the country working tirelessly to understand more about it.
00:12The fact that there were people reporting respiratory symptoms was a sign that there might be something more.
00:19Now, a new study from the University of Technology Sydney has identified
00:23Karenia cristata as a species generating harmful brevatoxins, responsible for the shutdown of some shellfish production.
00:31There's five species of Karenia that we found in this bloom,
00:34and generally across the entire period, Karenia cristata was the dominant one.
00:39The findings, now being peer-reviewed, challenge previous beliefs that Karenia mikimotoi was the dominant strain.
00:46Karenia blooms everywhere in the world tend to be mixed.
00:50Blooms with different Karenia species present.
00:53The government says it's another piece in an ongoing puzzle.
00:56Nearly every week we learn something new,
00:58so this is just another important clarifying piece of information for us to consider.
01:03It doesn't change the health advice at all.
01:05The latest algal bloom data shows no Karenia detected at 14 of 21 metropolitan sites,
01:11with low levels at the remaining seven.
01:14Good signs at the moment.
01:15We still need to make sure that we keep our foot on the accelerator
01:19in terms of surveillance.
01:21But, Professor Steer says, at offshore sites including in the Gulf St Vincent,
01:26Southern Fleurieu and Franklin Harbour,
01:28Karenia is still at moderate to high levels.
01:31Scientists agree it's an evolving situation.
01:34For all the incredible information which is out there,
01:37it's not enough to say this is exactly what's going to happen next.
01:40The latest findings, just the beginning,
01:43in what's likely to be an ongoing surveillance and research effort
01:46for waters here and abroad.
01:48End abroad.
01:49End abroad.
01:50End abroad.
