Crayfish surveys and field work

by Martin Asmus

Hi, my name is Martin Asmus and I am a technician at Charles Sturt University, Wagga Wagga, NSW, Australia. Being a keen fisher and ecologist I quickly realised that the poor Murray Crayfish needed some attention in terms of research. In 1997 I started a two year study of Murray Crayfish. This study examined the effects of recreational fishing on population parameters of Murray Crayfish ( Euastacus armatus ) in the Murrumbidgee River. A population survey was conducted over the two years at 12 sites along the river ( about 410km's ) In addition, a recreational fisher survey was undertaken to assess crayfishing habits of fishers and their knowledge of current NSW Fisheries regulations concerning Murray crayfish. The following photos were taken during the survey.
