Hydrobiology has recently conducted groundbreaking tests to determine the viability of hydroacoustics to identify elasmobranchs (sharks and rays), without requiring netting. Hydrobiology was commissioned by Rio Tinto Alcan (RTA) to undertake a survey of elasmobranchs (cartilaginous fish such as sharks and rays) near Weipa. Traditionally, surveys of this type are undertaken using methods which involve…
Hydrobiology and Sustainability Oceans have partnered to trial the use of hydroacoustics to monitor biomass in artificial reef systems – a necessity for evaluating the effectiveness of fisheries management plans. Monitoring artificial reefs is an important tool to determine the return on investment for fisheries management. However, common sampling methods are labour intensive, provide only…
Updates on projects in Queensland and the Northern Territory. Andy Markham has been assessing the response of streams in the Lockyer Valley to the devastating floods of 2011 and 2012. The floods triggered a new phase of erosion and sedimentation processes that have altered the morphology and hydraulics of the creeks. This information will be…
