Having live fish in a tank is a sure way of attracting a crowd at an event. NFS coordinators would often bring along a Perspex fish tank with a diversity of fish – these could be native and exotic species relevant to the particular area, depending on the educational message of an event. Fish were sourced either from aquariums, or from the field locally with relevant government permits.
Field staff would often collect the fish prior to, or during an event, which also provided the opportunity for the public to see survey techniques in action. Seeing live fish and especially seeing fish collected from the water directly in front of people, was a particularly powerful tool to engage, enthuse and excite many audiences.
