ANGLERS are being asked to help scientists monitor harmful algal blooms with a new app. The Centre for Ecology & Hydrology keeps tabs on harmful blooms which can threaten public health as well as animals. The Centre is asking dog walkers, swimmers, boaters, anglers and anyone else near fresh water to record the presence of harmful algal blooms with the ‘Bloomin’ Algae’ app that it has created in collaboration with environmental and health agencies. App users submit a photo of the bloom to the Centre, adding details of what activity takes place at the location, so that potential risks can be assessed. The app includes an algal guide and all verified records can be easily viewed on an interactive map. Android users should search Bloomin’ Algae at play.google.com; Apple users at the iTunes app store.
