Algal bloom threat to fishing on North Shore

INCREASING accumulations of algal bloom along Noosa North Shore beaches has made fishing all but impossible at any other time than the full tide.

Teewah fishing expert Lindsay Dines first warned of the threat last month fearing there would eventually be a repeat of the infestation of Laguna Bay that started in the summer of 2002-03 and continued for three years.

Mr Dines said there had been a marked increase in the bloom from the Third Cutting north. "There are thick patches of hincksia and plenty of it,'' he said.

"The fact it's here now and we are heading into drought means we are in trouble. The guys on the beach were saying it is unfishable unless on full tide.

"Unless we understand the causes and do something about it, hincksia may become a permanent feature. It has the potential to become a major problem.''

Lloyd Consulting Environmental Services head Trevor Lloyd is a water quality expert who helped established the SEQ Healthy Waterways program. He agrees that the hot, dry conditions were ideal to trigger a bad plume.

Mr Lloyd said phosphorus and iron content in the water may also act as triggers.

Noosa Council last month began gathering information about the nature and scale of algae accumulations at Noosa.

At that point the Healthy Waterways Coastal Algae Working Group had no reports of coastal algae blooms in south-east Queensland.

Environmental services head Ben McMullen said at the time it was too early to determine council's response.
