Algal Bloom at Esperance’s Port Beach

The Shire of Esperance is warning people to avoid contact with a sporadic algal bloom occurring at Port Beach, Esperance.

The Esperance Shire chief executive officer Matthew Scott said the bloom was likely to be Trichodesmium erythraeum – or more commonly referred to as red tide of sea sawdust.

“This type of algae can be identified by a yellow – brown surface scum with an oil slick appearance, and as it decomposes surrounding waters may take on a pinkish tinge and take on a pale green colour,” Mr Scott said.

Trichodesmium algal blooms have occurred at various locations along the West Australian coastline and tend to be transported by ocean currents subject to wind and tide movements.

Recreational activities such as swimming, wading, canoeing, shellfish collection in affected waters should be avoided, particularly where algal scumming or discolouration is visible.

Contact with algal scum can result in skin irritation and a rash may develop in sensitive people. Pets should also be kept away from water during the bloom.

Shire environmental health officers are monitoring the situation and signage has been placed in affected areas, however given the blooms movement with the prevailing winds we are seeking the assistance of the Esperance community to stay away from the bloom. Signs will be removed once the bloom has dispersed.

For further information contact The Shire’s Environmental Health Services on 9071 0600.
