The usually unheralded splendour of freshwater fish communities can be difficult to communicate to the broader community.  Underwater video footage can overcome this hurdle by shining a light on what lies beneath.  We have recently completed a short documentary and field guide depicting the fishes of the Indian Ocean Drainage Division (Pilbara Province).  The Pilbara Province extends from the De Grey River in the north, to the Irwin River in the south, and encompasses some of Western Australia’s largest rivers and spectacular gorges. The field guide and documentary depicts each of the native fishes that are found in freshwaters and includes some of the continents most threatened species, the region’s diadromous species and cave fishes, as well as highlighting the encroaching threat of feral invaders from the south. The Pilbara is divided into three sub-provinces, based on their aquatic fauna, and includes the Southern Pilbara Sub-province, the North West Cape Sub-province and the Northern Pilbara Sub-province, each of which contains endemic fishes and each with its own threats. These educational materials are useful tools for the wider community, including schools, and were funded through the Rangelands Natural Resource Management Program and the Western Australian Governments State Natural Resource Program. It is the second field guide and documentary for the freshwater fishes of WA, the first being a highly successful production focussing on the south-west ichthyological province which can be viewed at www.freshwaterfishgroup.com.  The south-west package has now been converted into 10 separate Teacher’s Guides (years 1-10) that directly link to the National Curriculum.
