Nicola Moss, The Canary Test - Levels of Tolerance. Synthetic polymer on canvas. 92 x 102cm. ©2010.Earlier in the year I was on an outing with the Redlands Bushcare Creek Crew group and took part in an activity of fresh water fish identification. At a site along Hilliards creek we set traps and identified several species of both exotic and native freshwater fish. We received information and identification brochures that listed various species in a range from most sensitive to most tolerant. I thought of this as being a bit like the 'canary test'. Species that could survive in the creek conditions gave an indication of the overall water quality. This work depicts a native Fly-specked Hardyhead fish.
