Algal Bloom

The Hon. N.J. CENTOFANTI (Leader of the Opposition) (14:53): Final supplementary: is the minister concerned that there are no restrictions on oyster movement due to risks associated with Karenia algal movement between waters, given the minister's comments in regard to protecting the reputation of the oyster industry?

The Hon. C.M. SCRIVEN (Minister for Primary Industries and Regional Development, Minister for Forest Industries) (14:53): I thank the honourable member for her supplementary question. I think what needs to be taken into account is the assessment that was done in terms of other ways that Karenia could be moved. For example, we have not banned the movement of boats from an area that has Karenia to an area that does not have Karenia. There are many ways in the natural environment that Karenia can be spread. Karenia is present in many locations at any time, well before the algal bloom. It is a type of algae which is not unknown, in general terms, well before the algal bloom in South Australia eventuated.
