Biography

Born and raised in Germany, Kilian moved to England to complete an interdisciplinary undergraduate degree in Ocean Science at the University of Plymouth. Discovering his love for marine biology during the Ocean Science degree he decided to specialize in the field by pursuing a Master of Research degree at the University of Plymouth in collaboration with the Marine Biological Association of the United Kingdom, focusing on the use of underwater video technology for the mapping of benthic assemblages in a marine spatial planning context.

This was followed by a position as a postgraduate research assistant at the University of Plymouth’s Marine Biology and Ecology Research center. He then moved to Hobart to undertake his PhD at UTas/CSIRO, again focusing on spatial ecology in a conservation/fisheries context by exploring novel methods for quantifying movement behavior of free-ranging fish from telemetry data. Since completing his PhD in 2013, Kilian has been employed as a postdoctoral research fellow at the IMAS Fisheries and Aquaculture Centre.

Research Themes

Kilian’s main research interest is in spatial marine ecology with a current focus on using telemetry technology to quantify the behavior of mobile marine species in a fisheries, aquaculture or conservation context.

In his current role as co-investigator and day-to-day coordinator of the Sense-T project “Sensing Macquarie Harbour - Salmon sentinels and sensor strings: real time environmental information and networking solutions to underpin a Decision Support System (DSS) for the Tasmanian salmon industry” Kilian is working on using cutting edge acoustic telemetry technology to make further improvements to sustainable aquaculture production in Macquarie Harbour and study the effects of low levels of dissolved oxygen on the behavior of salmon in aquaculture cages.

Sense-T Stage 2: Sensing Macquarie Harbour (2015 - 2016)$677,100
Description
This Sense-T project brings together the Tasmanian Salmonid Growers' Association, IMAS and CSIRO to collect and analyse data from salmon farms in Macquarie Harbour. Sensors will be attached to individual 'sentinel' fish in pens in addition to sensors in the environment. Data will be collected on fish behaviour as well as environmental conditions such as water temperature, dissolved oxygen and depth. This will: help to reduce feed wastage by ensuring fish are fed when environmental conditions are suitable; collect new or previously difficult to obtain information about the harbour environment and the impact of salmon farming on variables such as oxygen levels; improve the salmon industry's efficiency and productivity; provide real-time data to support decision-making; and, highlight areas where the industry could improve its environmental practices.
