In response to months of improved beach conditions and latest monitoring trends, the State Government is now in a position to adjust some of its Algal Bloom Summer Plan response measures. Water testing results show the vast majority of South Australia’s coastline continues to record zero or low levels of the Karenia algae species, building on the encouraging monitoring data over the past three months.

Public consultation is now open on proposed changes to blue swimmer crab rules in the West Coast bioregion to make the rules easier to understand and to provide better fishing experiences for recreational fishers.

A Lancelin based shark fisher says there has been no commercial fishing in the West Coast bioregion between Lancelin and Tims Thicket (south of Mandurah) for nearly 20 years ... Mr Stokke, who also partners with his brother in a western rock lobster boat, said he thought the ban was probably targeting the wet liners but they (the shark fishers) were thrown under the bus with them.

Preparations for a large-scale limestone shellfish reef – the first delivered under the Malinauskas Government’s Summer Plan – are underway on the Yorke Peninsula, in one of the biggest marine restoration projects ever undertaken in South Australia.

Michelle Daw. Stansbury oyster growers have cautiously welcomed the reopening of their harvesting area, which had been shut since early May. Growers were informed of the reopening mid-afternoon on Wednesday, December 31 — too late for them to sell for the lucrative Christmas and New Year's Eve markets.

Six hi-tech monitoring buoys which will automatically detect future harmful algal blooms before they reach our shores are being deployed across South Australian waters. The state-of-the-art oceanographic moorings are equipped with specific sensors for early detection of key harmful algal bloom (HAB) species such as Karenia.
