On 22 Nov. 2009 between 1700–1900 hours, eight individuals of Cherax quadricarinatus were captured at Little Guilin
Lake along a 15–20 m stretch of shore (1°21'24.26"N 103°45'13.60"E to 1°21'25.61"N 103°45'14.41"E) at the public
fishing area opposite the main granite wall. At that time, the crayfish were emerging from their shelters between the
submerged granite boulders to forage. The animals were caught by recreational fishermen using a short fishing rod and
raw pig skin as bait. If an individual was observed to be emerging, it was presented with the bait and if it approached
